The full range…<br />
…awaits visitors to the world’s leading trade fair for production<br />
technology in Hanover. EMO HANNOVER <strong>2023</strong> scores with<br />
a unique range of technology that covers the entire spectrum<br />
of production technology. From machining centers and lathes<br />
to cutting tools and clamping devices to measuring equipment<br />
and control systems. The show covers all the major topics in the<br />
industrial value chain, presenting current state of the art and<br />
possible future scenarios for the coming developments.<br />
It is important for visitors to filter through the innovations and<br />
new developments that can be used to advance their own<br />
manufacturing and production. This issue of hp tooling, with its<br />
extensive EMO section, aims to help. Readers of this issue will also<br />
find in-depth information on the three major trend topics at the<br />
show – digitalization, additive manufacturing and sustainability<br />
in production.<br />
One more word on sustainability: it not only affects production<br />
itself, but starts with the tool used, the coolant used and through<br />
every individual step. Circular economy is the key word. It<br />
can extend the life cycle of products and raw materials to the<br />
maximum, for example by sharing, leasing, recycling, repairing<br />
and refurbishing. When it comes to optimizing production<br />
processes, digitalization – also in combination with artificial<br />
intelligence – leads to higher quality and more cost-effective<br />
products.<br />
Irrespective of the current topics, EMO will show whether the full<br />
range will lead to full order books. Experts are expecting the first<br />
indications of whether or not the currently gloomy global business<br />
outlook in the machine and tool building sector will recover in the<br />
foreseeable future.<br />

The perfect connection<br />
Special tools from Horn<br />
It was autumn 1955 and the wind was blowing the last<br />
brown leaves from the trees. As Otto Dunkel watched his<br />
leaf rake doing its job, he had a brilliant idea. That was the<br />
birth of the wire spring contact. Today, ODU GmbH & Co.KG<br />
(Otto Dunkel) is one of the world’s leading companies for<br />
the development and production of connector systems. For<br />
the production of the high-end connectors, the company relies<br />
on precise Swiss-type turning machines and tools from<br />
Paul Horn GmbH. For about 20 years the two companies have<br />
been working together closely, to ensure that the demanding<br />
machining tasks are optimised for producing the perfect connector.<br />
The close partnership will continue, especially with<br />
regard to the machining of lead-free brass and other alloys.<br />
Similar to the individual twigs of his broom, Otto Dunkel<br />
divided the contact surfaces into individual springs, resulting<br />
in a multitude of contact points. The result was a revolution:<br />
constant contact resistance and consistent contact pressure.<br />
With this the weak point of message transmission systems,<br />
namely the unreliable plug-in contact, was finally overcome.<br />
Founded in 1942, the ODU group of companies now<br />
has 2,500 employees worldwide. The headquarters of the<br />
Bavarian company is located about 80 km east of Munich in<br />
Mühldorf am Inn. ODU supplies connector systems, among<br />
others, to the medical industry, the measurement and testing<br />
sector, industrial electronics, the military and the automotive<br />
industry. It is noteworthy that ODU developed the first highcurrent<br />
connectors for electromobility.<br />
For micro-machining and other cutting operations, ODU<br />
relies on tool solutions from Horn and machines from Tornos<br />
The S274 µ-Finish system is efficient for<br />
micro-machining of components<br />
Horn tools<br />
“In the past we often ground tools ourselves for machining<br />
special connectors. However, with quantities of<br />
several hundred thousand per year, we need process-reliable<br />
and productive tooling systems,” says ODU tool manager<br />
Tobias Fuchshuber. “Our cooperation with Horn has existed<br />
for about 20 years.” Horn field service representative<br />
Michael Götze has been involved from the beginning: “During<br />
this extended period we have been able to solve numerous<br />
machining problems at ODU. Its employees are always open<br />

The N105 broaching system can be adapted to<br />
many applications<br />
To ensure a good contact, a high surface finish is an<br />
important quality feature of a plug connector<br />
to new tool technologies and we often test new products there<br />
as a result.” ODU relies on numerous Horn tool systems.<br />
“The machining tasks at our company are very diverse. On<br />
more than 175 sliding-headstock lathes we machine micro<br />
components of a few tenths of a millimeter in diameter up<br />
to parts of 0 30 mm”, says Fuchshuber. Tools from Horn are<br />
used in all areas of production. From the µ-Finish system<br />
S274 for sliding-headstock turning of micro components to<br />
internal turning and grooving. At ODU 80 % of the material<br />
processed is brass. Aluminum, copper and stainless steel<br />
account for the remaining 20 %.<br />
It’s the surface that counts<br />
For contacts in particular, high surface quality is a decisive<br />
feature. For turning contact pins, ODU relies in part on the<br />
Horn tool system S274 in the µm finish variant. Grinding a<br />
sharp and almost flawless cutting edge on a tool requires a<br />
lot of know-how. Grinding wheels with the finest grits, special<br />
grinding techniques and a microscope with 400x magnification<br />
are necessary to ensure that the tool performs as<br />
required. Every batch of the µ-Finish system is subject to<br />
100 % inspection. Important criteria for quality assurance are<br />
the high-tolerance surface quality of the rake and flank surfaces,<br />
the center height and especially the sharpness of the<br />
cutting edge. Irregularities on the cutting edge of more than<br />
0.003 mm are considered to be out of tolerance.<br />
For the production of a coupling of a wire spring contact,<br />
Fuchshuber was looking for a new tooling solution. “The<br />
problem with drilling the component is the special shape of<br />
the base of the hole,” explains Fuchshuber. ODU manufactures<br />
the brass component in seven different variants from a<br />
bore 0 of 1.43 mm up to 3.6 mm. “Before we switched to the<br />
Horn tool, we pre-drilled the holes and then bored them out<br />
with a tool we ground ourselves,” says Fuchshuber.<br />
DS cutter of special shape<br />
In series production, however, problems arose due to impeded<br />
chip flow. In addition, there was potential for reducing<br />
the machining time further. With several hundred thousand<br />
parts per year, this was a decisive factor. Horn provided<br />
the solution with the DS milling system with internal coolant<br />
supply. The milling cutters are ground with a special<br />
shape. When plunging into the solid, a hole is produced with<br />
the same shape at the base. All of the seven cutter variants<br />
are ground with sharp cutting edges, which are uncoated.<br />
The changeover to the milling tools resulted in the saving of<br />
one process step and also in an increase in process reliability<br />
due to the controlled chip evacuation. In addition, the cycle<br />
time was significantly reduced. “Conversion of the seven tool<br />
variants only took about twelve weeks. The speed with which<br />
Horn reacts as well as the fast delivery noticeably shorten<br />
the time it takes to change over our machining processes,”<br />

The special tool for<br />
broaching the location key<br />
Broaching the location key was a<br />
challenge in the tool design<br />
says Fuchshuber. He relies on<br />
a Tornos DECO 10 sliding-headstock<br />
lathe to produce the component.<br />
Working closely together for 20 years:<br />
Peter Ortmaier, Tobias Fuchshuber and Michael Götze<br />
sources HORN/Sauermann<br />
Further special tools from Horn are<br />
used for machining a casing bushing. For<br />
two axial grooves, Fuchshuber relies on the<br />
Supermini system type 105. The grooves have 0 of<br />
11 mm and 7.7 mm. The special feature is that a thin-wall web<br />
of 0.2 mm must remain between the two grooves. The required<br />
tolerances are very tight. Here, too, a special tool optimised<br />
for machining brass is used. The tool is sharp, uncoated<br />
and has a polished rake face. Inside the turned part, a Supermini<br />
tool broaches a 20 mm long, 1 mm deep,<br />
fail-safe keyway in four strokes. The keyway<br />
ensures that the plug can be pushed into the<br />
socket in one orientation only. At the end of the<br />
groove, an internal recess serves as a relief for the<br />
broaching tool. This component is manufactured<br />
at ODU on Tornos DECO 13 and DECO 20 lathes.<br />
Broaching of a locating key<br />
“We were given the special task of producing a connector<br />
housing. We were required to broach a circular groove,<br />
rather than a linear one. However, a locating key with a width<br />
of 3 mm had to remain within 0 of 13 mm,” explains Götze.<br />
“We previously embossed the key from the outside but wanted<br />
to eliminate this operation,” adds Fuchshuber. The solution<br />
was a broaching tool of oval shape with the form of the<br />
key recessed on one side. During machining, first the inside<br />
is turned so that a ring remains. Then the tool enters<br />
the workpiece and commences the broaching process. Machining<br />
is started at one position. As soon as the diameter<br />
is reached, the spindle turns the workpiece through 90 °, a<br />
process that is repeated four times until the inner diameter<br />
is circular and the locating key remains in the correct position.<br />
The total machining time for the broaching process is<br />
around 20 s.<br />
The successful cooperation between ODU and Horn will<br />
continue to grow ever closer in the future, especially with regard<br />
to the machining of lead-free brass. The elimination of<br />
lead as an alloying element worsens the machinability of the<br />
material. This presents users as well as tool manufacturers<br />
with new difficulties. “Lead-free brass will present us with<br />
new challenges in the productive machining of our components<br />
in the near future. However, with tool partners such as<br />
Horn ready to assist, we see ourselves well looked after in this<br />
area,” says Fuchshuber. EMO <strong>2023</strong>, hall 8, booth A24<br />

Extensive portfolio for automated electrode production<br />
“Marathon” tools with a license for precision<br />
oil, ideally with internal shaft cooling at the<br />
same time. So surely a combination is out of<br />
the question.<br />
Not necessarily, because in the meantime<br />
there are very good filter systems for liquid<br />
cooling lubricants, making it an interesting<br />
option to wet-mill copper and graphite electrodes<br />
on the same machine. This results in<br />
users achieving maximum flexibility as well as<br />
better utilisation of the machines integrated<br />
into the automated system. In combination<br />
with ZECHA’s highly precise and reliable<br />
milling tools, this enables optimally calculated<br />
and safe production workflows and milling<br />
processes.<br />
Laser sharp and proven in mould making: the IGUANA series from<br />
ZECHA Hartmetall-Werkzeugfabrikation GmbH is the diamond coated<br />
solids carbide milling series with extremely sharp cutting edges and endurance<br />
Consistently high quality and maximum flexibility aren’t only<br />
key features in mould making. Maintaining maximum efficiency<br />
means one has to use high performance, high-end tools.<br />
Because once these are acquired, the next step comes: low manpower, automated<br />
production. Unthinkable? ZECHA Hartmetall-Werkzeugfabrikation<br />
GmbH is banging the drum for mixed machining with an intelligent tool<br />
selection.<br />
The mould making companies’ ability to compete depends completely on<br />
their automation. In addition to machining, this especially includes the clever<br />
connection and coordination of all manufacturing technologies needed for<br />
component production. This includes erosion, laser machining, as well as<br />
component cleaning and measurement. An essential aspect is the milling<br />
of usually very demanding materials – the perfect area of application for<br />
ZECHA Hartmetall-Werkzeugfabrikation GmbH’s high precision micro tools.<br />
It’s all in the mix<br />
At first glance some things just don’t seem to go together: who would ever<br />
think of machining graphite and copper on the same machine? “Most people<br />
immediately dismiss it.” according to Andreas Weck, application engineer at<br />
the company. “But the solution is mixed machining! This is the machining of<br />
different materials that usually aren’t machined with the same cooling lubricant,<br />
in this case combining graphite and copper electrode machining – two<br />
strategies that couldn’t be more different.”<br />
This is because graphite is usually dry milled on specially configured<br />
milling machines with particularly powerful extraction systems and the corresponding<br />
ventilation. Whereas copper is impossible to dry machine and<br />
therefore requires a differently configured milling machine with emulsion or<br />
Laser sharp and high precision<br />
IGUANA cutters are a good fit for all<br />
non-ferrous metals<br />
One tool series has already become the perfect<br />
partner in mould making in a very short time:<br />
the unique IGUANA cutter series. These solid<br />
carbide tools with up to three cutting edges<br />
have a sealed diamond coating resharpened<br />
by laser. Dennis Thiermann, application engineer<br />
at ZECHA, explains: “The coating process<br />
inevitably leads to a cutting edge radius<br />
of the same order of magnitude as the coating<br />
thickness, which can be considerably more<br />
than 0.01 mm. This is reworked by means of<br />
a laser either on the rake and flank surfaces<br />
or only on the flank surface. This gives us<br />
a consistently sharp cutting edge radius of up<br />
to 1 µm. At the same time coating defects, socalled<br />
clusters, are smoothed out.”<br />
Because of their sharp cutting edges,<br />
IGUANA tools have become standard when<br />
machining different materials, such as aluminum,<br />
copper, all types of brass as well as simple<br />
and fiber-reinforced plastics. These tools<br />
are even used in the machining platinum.<br />
In the meantime there are five sub-series.<br />
In addition to the original range layered on<br />
both sides, there are also tools with edge protection,<br />
helix or shank cooling as well as helix<br />
and shank cooling. These tools are available<br />
as ball, torus and end mills, the series with<br />
shank cooling as torus and end mills. Drills<br />
are also available. The new 935 series completes<br />
all of the copper electrode mould making<br />
needs by being available in the usual free<br />
lengths and corner radii.<br />

A top performance<br />
thanks to the lowest tolerances<br />
In many cases this technology has already been able to increase<br />
process reliability. “Above all, since the tool life and<br />
dimensional accuracy can maintain an excellent level over<br />
extremely long periods, users benefit straight away. In contrast<br />
to PCD tools, which are usually only available with<br />
one cutting edge in small diameters, IGUANA cutters have<br />
up to three cutting edges,” says Mr. Thiermann.<br />
The lowest possible production tolerances, such as an<br />
impressive 2 µm concentricity and form accuracy of +/-<br />
5 µm, optimise quality, especially when finishing fine surfaces.<br />
This often eliminates time-consuming remachining<br />
which in turn reduces process costs. Moreover, there is<br />
an upward trend in overall economic efficiency thanks to<br />
longer tool life and therefore few tool changes.<br />
Further strong tool partners<br />
Despite IGUANA’s strengths in mould making, there are<br />
still a few partners in the ZECHA product range capable<br />
of increasing ones possibilities. These include the graphite<br />
cutters and the steel cutters from the PEACOCK range (including<br />
CBN) and the new QUEEN BEE tools.<br />
PEACOCK tools are the multi-talents for hard and powder-metallurgical<br />
steels up to 70 HRC, such as cold and hot<br />
work steels, PM steels, special alloys or tungsten copper<br />
with more than 50 % tungsten content. There is an extensive<br />
range with mould-optimised total and free lengths.<br />
The F-series enable a very high metal removal rate and the<br />
whole tool series produces excellent surface qualities.<br />
capacity, they can withstand any marathon machining session –<br />
unmanned, overnight or even the entire weekend.”<br />
For hard cases: CBN<br />
Occasionally in mould making, hard and powder metallurgical<br />
steel of up to 70 HRC simply can’t be avoided. This requires<br />
a particularly tough cutting material to withstand the intense<br />
temperatures in the machining process. Cubic crystalline boron<br />
nitride (CBN) is the ideal counterpart for such tough jobs,<br />
as it combines a high hardness and fracture resistance, even in<br />
interrupted cuts, with high thermal and chemical resistance.<br />
“In a way, it’s a trick to heat up the material for machining,<br />
making it softer which leads to longer tool life.,” explains Mr<br />
Thiermann.<br />
At the same time, CBN has a very high density and resistance<br />
to cracking and diffusion. It enables a homogeneous and even<br />
cut, which also contributes to very good surface finishes. Overall,<br />
CBN cutting materials offer high reliability, tool life and<br />
accuracy when machining steels of up to 70 HRC<br />
High performance tool life champions<br />
Not wanting to worry about precision, tool life and quality in<br />
machining processes when mould making, it’s best to use tried<br />
and tested milling tools. In order to get the most in terms of<br />
efficiency, mixed machining and automation solutions show<br />
the road into the future. “And,” as Mr Weck states, “with our<br />
extensive tool portfolio, our tool users are well prepared for<br />
current and future challenges!”<br />
further information: www.zecha.de<br />
The QUEEN BEE 589 series ball and torus cutters<br />
promise process-reliable machining of steels up to 58 HRC,<br />
nickel based alloys, titanium and special materials up to<br />
1,800 N/mm 2 . The cost-optimised specifically for mould<br />
making adapted tools are available 0 0.8 to 12 mm. Solid<br />
tool properties, coupled with the latest coating technology,<br />
increase tool life and minimise tool changes. Furthermore,<br />
you get very smooth surfaces and less material adhesion.<br />
Maximum precision and cutting quality<br />
Both tool concepts, PEACOCK and QUEEN BEE, combine<br />
the performance potential of the latest solid carbide grades<br />
with finely tuned tool geometry and state-of-the-art PVD<br />
coating. The carbide offers a high level of hardness and<br />
toughness at the same time, making it very stable. Thanks<br />
to their optimised micro-geometry, these tools achieve low<br />
cutting forces and a smooth cut. The coatings possess an<br />
impressively smooth and homogeneous surface, temperature<br />
resistance, strength and damping, as well as the best<br />
possible coating adhesion.<br />
Thanks to the lowest manufacturing tolerances, a concentricity<br />
of 3 µm and a shape accuracy of +/- 5 µm, these<br />
series are particularly interesting for finishing fine surfaces.<br />
Andreas Weck: “Both are perfectly suited for wet and<br />
dry milling. This makes them the perfect choice for mixed<br />
machining, automation and demanding applications with<br />
long running times. Thanks to their high mechanical load

New high performance cutter for the<br />
highest demands on productivity<br />
The new HPC milling cutters from LMT Tools enable maximum metal removal rates<br />
and the highest dimensional accuracy with first-class surface quality<br />
LMT Tools is one of the most renowned experts in<br />
the development and production of precision tools,<br />
and sets regularly technological trends in the market<br />
with its high innovative strength and tool expertise.<br />
The latest coup: new high-performance milling cutters<br />
for high-performance cutting.<br />
The HPC family combines the proven DHC Premium, DHC<br />
INOX Premium, DHC Slot and DHC Hardline tool series<br />
and, thanks to improved technology, achieves a significantly<br />
higher metal removal rate. Considerable increases in productivity<br />
with optimum process reliability are thus guaranteed.<br />
High performance cutting (HPC milling) requires highperformance<br />
tools that can optimally withstand the strains<br />
caused by the high cutting speed and feed rates involved in<br />
the process and ensure cutting with as little vibration as possible.<br />
With the new HPC family, the tool expert offers the perfect<br />
solution. The cutting geometry, coating and cutting-edge<br />
treatment have been specially adapted to the special requirements<br />
of high-performance machining and enable maximum<br />
metal removal rates and high dimensional accuracy with<br />
first-class surface quality. The unequal pitch ensures maximum<br />
smoothness and process reliability, while the surface<br />
quality of the machined workpieces is a further advantage.<br />
The optimum high performance cutter<br />
for every material<br />
Whether trochoidal, side, corner and groove milling or ramps<br />
up to 0 0.5x – the HPC family is designed for a wide range<br />
of applications. There are four versions available: HPC P,<br />
HPC M, HPC UNI and HPC H. The HPC P is the specialist<br />
for higher alloyed steels and castings with a tensile strength<br />
of 900 N/mm 2 or higher. An edge protection bevel reduces the<br />
load on the cutting edge and ensures optimal performance in<br />
the demanding machining of abrasive materials. The HPC M<br />
excels in the machining of austenitic steels, non-ferrous<br />
metals and titanium. The positive cutting-edge geometry and<br />
special coating ensure efficient machining of materials that<br />
usually have higher toughness and are therefore difficult to<br />
machine.<br />
The HPC UNI is a three-flute cutter (all other variants being<br />
four-flutes) and therefore provides a larger chip space.<br />
With excellent chip removal, it is ideally suited for full slot<br />
milling in a variety of materials (P, M, K, N and S). Each flute<br />
has a different helix angle. The HPC H is the best choice for<br />
hardened steel up to 55 HRC. Its targeted edge rounding results<br />
in a particularly stable cutting-edge, allowing for very<br />
high feeds in hardened and high-strength materials up to<br />
1,600 N/mm 2 .<br />
Maximum tool life and productivity<br />
The new HPC family replaces the well-known DHC family.<br />
By optimizing production processes and using state-of-theart<br />
technology, tool life and productivity have been significantly<br />
increased compared to the previous series. “With our<br />
new high performance cutters, high cutting speeds and feeds<br />
can be achieved, resulting in high chip volume and increased<br />
productivity,” says Marcus Paul, global head of product management<br />
and emphasizes: “Compared to the previous families,<br />
we have managed to increase the metal removal rate by<br />
more than 30 % and achieve a tool life increase of up to 70 %.”<br />

The best deep bores with PCD<br />
materials & tools<br />
When the Schlote Group built a new factory in<br />
Harzgerode in 2017, it was designed to mass produce<br />
only a single part. MAPAL supplied all the cutting<br />
tools. By optimising the tools, the foundation has now<br />
been laid for a future with new products.<br />
Schlote’s story begins in 1969 as a small workshop in<br />
Harsum, where the company is still headquartered. Today<br />
eleven companies with 1,800 employees belong to the Group.<br />
The OEM has eight factories in Germany as well as further<br />
manufacturing facilities in the Czech Republic and China.<br />
Schlote Group customers include big car manufacturers, system<br />
integrators and foundries. Schlote’s turnover stems from<br />
engines (55 %), transmissions (39 %) and chassis (6 %).<br />
Already at other sites a successful cooperation with<br />
Trimet Aluminium existed, manufacturing finished car components<br />
from cast blanks. The awarding of a contract for a<br />
component by a major OEM, involving very high quantities,<br />
led to a joint venture between Schlote and Bohai Trimet in<br />
Harzgerode.<br />

More than 4,000 clutch housings<br />
per day<br />
The part being manufactured in Harzgerode<br />
is a clutch housing made of die-cast aluminum.<br />
A single version of the automatic transmission<br />
is being delivered to various major car<br />
manufacturers, where they are predominantly<br />
installed in vehicles with two-liter engines.<br />
The bell housing connects the transmission to<br />
the engine. While the transmission side is the<br />
same on all the clutch housings, the other side<br />
is adapted to the respective car manufacturer’s<br />
engine. The differences are mostly small,<br />
so the bell housing construction is 99 % identical<br />
for all of the car manufacturers.<br />
A manufacturing cell at Schlote is made up of three machining centers from<br />
SW; two W06 double-spindle machines and a one6 single-spindle machine<br />
Schlote Harzgerode GmbH is currently producing<br />
4,000 parts per day. At over 80 % the<br />
modern factory exhibits a very high degree<br />
of automation. Five days a week around the<br />
clock 120 employees work at the Harzgerode<br />
site. Production can be expanded to six or<br />
seven days a week if need be.<br />
As is the case for the entire automotive industry,<br />
the requirements placed on parts are<br />
very high here. “The part is not only an adapter<br />
flange, but also the back of the transmission.<br />
The bearing seats thus require the highest<br />
degree of precision”, explains Sebastian<br />
Swiniarski, work preparation team lead at<br />
Schlote. The part requires many bores with<br />
different tolerances, whereby precision manufacturing<br />
is needed down to the thousandth of<br />
a millimeter.<br />
Deep drilling is one of the machining steps that takes place on the<br />
double-spindle machine; bores 180 mm and 141 mm deep are created<br />
with an 8 mm drills from MAPAL<br />
The first machining steps for the clutch housings occur on<br />
double-spindle machines; while machining takes place at the back,<br />
new parts can already be clamped at the front<br />
MAPAL and Schlote can look back on<br />
many years of effective cooperation. MAPAL<br />
is therefore entrusted with supplying PCD<br />
milling cutters (which create the defined<br />
rough surfaces on which sealant is applied),<br />
tap drills, reamers and an array of diverse<br />
drilling tools. “We offer our customers comprehensive<br />
solutions including the development<br />
of entire processes”, says Stefan Frick,<br />
MAPAL’s technical advisor to Schlote.<br />
Successful improvement process<br />
From the very beginning on a watchful eye<br />
was kept on the implemented tools. Since<br />
Harzgerode went into operation, analyses<br />
have been performed continuously to find<br />
possible weak points and optimise manufacturing.<br />
Within the context of this continuous<br />
improvement process, Schlote and MAPAL<br />
have managed to achieve longer tool lives,<br />
lower tool expenditures and higher production<br />
quantities over years. While 3,600 parts<br />
per day were produced at most in the beginning,<br />
the limit has now been raised to 4,500<br />
parts –without needing more machines.<br />
14 no. 3, August <strong>2023</strong>
materials & tools<br />
The newest optimisation involves deep drilling for oil<br />
channels used to change gears in the automatic transmission.<br />
“We evaluate every month with our tool management<br />
system which tools have to be exchanged how often”,<br />
Swiniarski reports. “Time and again the deep drills have<br />
proven to be particularly sensitive. As these drills are<br />
relatively cost intensive, we have concentrated on them<br />
to further cut our tool costs.” Quality aspects are also inherent<br />
in tool wear as a blunt drill produces burrs at the<br />
bore exit.<br />
In this particular case, two of five deep bores are involved<br />
with a 0 of 8 mm and cutting depths of 180 mm and 141 mm.<br />
They run through the part from the side up to the bearing<br />
seat in the middle. Up to now solid carbide tools were used<br />
for this, which is standard for deep bores. Schlote was able<br />
to achieve a tool life of 2,500 parts in this way. The load<br />
monitoring of the machine already registered tool wear<br />
starting at 2,000 parts though, and burrs could be seen at<br />
the bore exit.<br />
Significantly longer tool life with PCD<br />
When it came to optimising the deep bore, plant manager<br />
Tino Lucius, a former MAPAL employee, suggested PCD<br />
variants. And so the partners developed the idea of deploying<br />
a PCD tip for the deep drills. There was a lot to consider<br />
during the implementation, Frick relates: “It is not possible<br />
to construct this type of drill entirely out of PCD. Apart<br />
from the high costs, the brittleness of the material is a problem.<br />
There is also always the danger of chipping of the cutting<br />
edges during interrupted cuts. Good cooling must also<br />
be ensured as PCD is heat sensitive.”<br />
For the new tool MAPAL started with the existing solid<br />
carbide drill and inserted a PCD cutting edge at its tip. The<br />
structure of the tool is reminiscent of a concrete drill with<br />
a carbide tip. The manufacturers in Harzgerode are very<br />
happy with the PCD deep drill’s tool life. While the solid<br />
carbide drill’s tool life ends after 2,500 parts, the PCD<br />
version keeps going reliably up to 15,000 parts. There is<br />
further scope for improvement in machining challenges,<br />
such as blowholes in the material and varying casting<br />
quality. The partners are currently working on this together.<br />
“We have occasionally been able to achieve a tool life of<br />
40,000 parts. Naturally, we want to make this ultra-long tool<br />
life the norm”, Frick stresses.<br />
The future is electric<br />
Clutch housing manufacturing at the site was planned to last<br />
at least eight years with a peak output of 1.1 million parts<br />
per year. This peak was surpassed in 2020. Production has<br />
been ongoing for five years in the meanwhile with 900,000<br />
parts produced per year.<br />
Due to continuously improved productivity and the lower<br />
production quantities, there has been time to address future<br />
trends and produce different parts. The factory is already being<br />
modified for this purpose. The first of two new projects<br />
involves six different parts that Schlote is to produce for a<br />
hybrid model of super sports car manufacturer.<br />
In the other project Schlote’s expertise as a clutch housing<br />
manufacturer is once again called for – this time for an electric<br />
car. Schlote draws from the trend toward electric mobility<br />
by supplying e-cars with transmissions as well.<br />
For an innovative model with three gears, the connection<br />
between engine and transmission is to be produced in<br />
Harzgerode. Half of the factory capacity is currently being<br />
converted. The production of parts for combustion engines<br />
is to be ramped down to 50 %. In future hybrid cars<br />
will account for 10 % and purely electric mobility for 40 %.<br />
Schlote has already produced the first parts for the new<br />
projects.<br />

The cutting data is the same as that of the solid carbide<br />
drill at a spindle speed of 8,700 rpm, a feed of 0.3 mm/rev and<br />
a cutting speed of 218 m/min. The new drill’s potential lays in<br />
its considerably longer tool life, the resulting lower tool costs<br />
and the higher process reliability. Less tool changes also<br />
means less machine downtime.<br />
Production at Schlote in Harzgerode involves a total of<br />
ten manufacturing cells. Each cell is made up of three machines<br />
from the manufacturer SW, two W06 double-spindle<br />
machines and a one6 single-spindle machine. The parts are<br />
machined in three clamping setups, whereby the doublespindle<br />
machines handle the first two setups and finishing<br />
takes place during the third.<br />

HELLER continues to invest in Changzhou<br />
Production site to be significantly expanded<br />
Recognising the importance of the large Chinese market,<br />
HELLER has recently invested in its Changzhou<br />
plant, creating the conditions to produce more than<br />
100 machines per year on site. In the presence of local<br />
politicians, numerous key customers and the HELLER<br />
management, the extension building was officially<br />
inaugurated June 16, <strong>2023</strong>.<br />
As far back as the 1950’s, HELLER was already looking far<br />
beyond its European home market to China. The managing<br />
directors at the time made important contacts and began<br />
manufacturing machine tools for the local market. This<br />
led to several close collaborations with local distributors. The<br />
company was poised for growth, so in 2013 the Nürtingenbased<br />
machine tool manufacturer set up its own subsidiary<br />
in Changzhou, which is located in the center of the Yangtze<br />
Delta. At that time, a 7,000 m 2 service and assembly plant was<br />
built on a total area of 24,000 m 2 .<br />
Since then business has picked up strongly. In the beginning<br />
mainly with well-known companies in the commercial<br />
vehicle industry. Since the early 2020’s, HELLER has also<br />
increasingly won customers from the sectors of aerospace,<br />
mechanical engineering, hydraulics etc. For several years<br />
now the German company has been producing the universal<br />
machines required by these industries locally in Changzhou.<br />
This proved a crucial step because, according to Claude<br />
Ballay, general manager of HELLER China, experience shows<br />
very clearly that ‘local for local’ production is becoming increasingly<br />
important in the Chinese market. He explains:<br />
Regional machining center business in China is growing;<br />
currently HELLER China mainly produces the 4-axis<br />
H 6000 and the 5-axis HF 3500 and HF 5500 models;<br />
the H 4000 and H 8000 machining centers and the<br />
CBC 200 coating modules are also built here as needed<br />
HELLER China has invested in its local subsidiary in<br />
Changzhou, China, expanding its production and<br />
service floorspace from 7,000 m 2 to 9,000 m 2<br />
“Delivery times of three to four months are expected here<br />
and we have to be able to meet them reliably. What’s more,<br />
our customers understandably expect us to produce much of<br />
what we sell here in the country.”<br />
Accordingly HELLER began building its first machining<br />
centers for the so-called regional market four years ago. Local<br />
suppliers were contracted and in-house staff trained for<br />
assembly and ongoing quality control. The new strategy began<br />
to pay off very quickly. In spite of the Covid dip, business<br />
in the universal machine market in particular has grown and<br />
now accounts for almost half of total sales in China.<br />
New building adds 2,000 m 2<br />
In line with the ‘local for local’ strategy of the Chinese universal<br />
machine business, the management of the HELLER<br />
Group decided at the end of 2021 to expand the Changzhou<br />
plant. Construction began in the spring of 2022, and about a<br />
year later the new 2,000 m 2 building was completed and inaugurated<br />
June 16, <strong>2023</strong> in the presence of 30 VIP customers,<br />
local politicians and the HELLER management.<br />
A total of 9,000 m 2 of production floorspace is now available.<br />
The expansion has been key in enabling the company<br />
to produce a greater volume of machines in an efficient and<br />
cost-effective manner.<br />

EMAG starts construction of a new plant in Mexico<br />
On June 19, <strong>2023</strong>, the symbolic groundbreaking ceremony took<br />
place for the new plant of the EMAG Group in the San Isidro<br />
Business Park in Querétaro, Mexico. This marks the start of an ambitious<br />
investment program of the EMAG Group in the region.<br />
In the last decade the Mexican market has developed into an attractive<br />
production location for the USMCA (“United States Mexico Canada<br />
Agreement”) free trade zone, formerly NAFTA. This is due to several factors:<br />
the strategic location, attractive framework conditions for investment,<br />
a high level of training, a solid infrastructure and a long tradition in<br />
manufacturing.<br />
The symbolic groundbreaking ceremony for the new plant of the EMAG Group<br />
took place in the San Isidro Business Park in Querétaro, Mexico<br />
The global crises of recent years have led to<br />
a rethinking of the value chain and production,<br />
towards so-called nearshoring. Mexico<br />
has benefited from these crises and the misalignments<br />
of production. Industries such as<br />
automotive, aerospace, electronics and consumer<br />
goods are investing billions in existing<br />
and new production capacities.<br />
But Mexico is not just an extended workbench.<br />
Thanks to its good level of education,<br />
the country is home to more and more<br />
research and development sites of global<br />
companies. Against the background of this<br />
dynamic development and ever shorter investment<br />
cycles, the construction of the new<br />
EMAG plant is another step in the company’s<br />
20-year success story in Mexico. In the future<br />
the expansion of local competence and value<br />
creation will be of great importance.<br />
Since entering the market in 1997, EMAG<br />
has continuously invested in its presence in<br />
Mexico. After establishing a branch in Mexico<br />
City in 2003, a new headquarter was opened<br />
in Querétaro in 2015 with a production<br />
area of 420 m². EMAG Mexico was awarded<br />
Supplier of the Year in 2010 (AAM) and 2016<br />
(Sisamex) and was able to realize its first turnkey<br />
project in 2019.<br />

MAPAL moves into new building in Komorniki<br />
MAPAL Narzędzia Precyzyjne (MAPAL precision tools) in Poland got a new head office. MAPAL acquired a<br />
5,000m 2 premises in Komorniki, not far from the previous site in Poznań. A modern and generously equipped<br />
office building has now been erected there, the grand opening was in March 29, <strong>2023</strong><br />
In Poland the company serves the production<br />
plants of international automotive and<br />
mechanical engineering manufacturers<br />
among others. A collaboration with the commercial<br />
agency Gallo-Ex in Poznań that began<br />
in 1996 led to its takeover in 2002. Since 2005<br />
the branch office has been trading as MAPAL<br />
Narzędzia Precyzyjne. In 1997 MAPAL received<br />
a major order in Poland from a diesel<br />
engine manufacturer in Tychy, and in 2004<br />
it took on its first tool management project<br />
for the VW plant in Poznań. MAPAL’s reamers<br />
entered the Polish market as far back as<br />
the 1970’s. At that time the buyer was one<br />
of the largest ship engine manufacturers in<br />
the country.<br />

types including mechanical, air and electric motor<br />
driven styles are all available.<br />
These speed increasers help maximize productivity by<br />
achieving a higher spindle rpm that is required for certain<br />
applications in today’s marketplace. Small diameter<br />
tools require rpms that are sometimes not possible<br />
to reach with existing machine tools. In addition they<br />
allow for less wear and tear on the machine’s spindle<br />
when it is not required to run at its maximum rpm.<br />
Mechanical speeders are available with up to a 1:8 gear<br />
ratio and a maximum speed of 50,000 rpm. Air speeders<br />
can run continuously at up to 80,000 rpm and high<br />
frequency motor spindles can maintain up to 80,000 rpm<br />
with high torque, and have variable speed options.<br />
Many of the speeders have automatic tool change<br />
capabilities and are modular in design to offer the customer<br />
greater flexibility. Henninger also manufactures<br />
custom angle heads, live centers, face drivers, and live<br />

over 20 %.<br />
Fixed calculation basis for carbon-cutting targets<br />
The company has based its carbon-cutting targets on the figures<br />
from its 2020/2021 business year, in which CERATIZIT<br />
emitted almost 176,000 metric tons of CO 2 e (carbon dioxide<br />
equivalent) according to the GHG protocol (Greenhouse<br />
Gas Protocol). Around a quarter of the company’s emissions<br />
fall under scope 1 of the protocol (direct GHG emissions) and<br />
a quarter from scope 2 (electricity indirect GHG emis sions),<br />
while around half fall under scope 3, which stem in particular<br />
from purchased goods and services as well as employees’<br />
trips to and from work.<br />
“With these final figures we have the necessary information<br />
to take the first steps to reducing our carbon footprint.<br />
Switching to renewable energy is only the first step in this<br />
process, but one that has enabled us to reduce our footprint<br />
by more than 20 %,” explains executive board spokesperson<br />
Andreas Lackner. With the figures now available the company<br />
will decide on further measures to be taken over the next<br />
few months to reduce the company’s corporate carbon footprint<br />
(CCF) by at least 35 % as currently planned by 2025.<br />
The company has set itself the target of reducing its<br />
2020/2021 CCF levels by 60 % through additional measures<br />
by 2030, such as switching to ‘green’ hydrogen. The company<br />
plans to achieve ‘net zero’ by 2040, ten years ahead of the<br />
targets specified under the Paris Agreement.<br />

5 th leading trade fair for deburring technology<br />
and precision surface finishing<br />
Whether the mobility and energy transition, sustainability, health<br />
or safety is involved – global megatrends have a profound effect on<br />
industrial production. They’re also impacting demands placed on<br />
burr-free components, as well as cleanliness and surface finishing<br />
quality. As the only international trade fair for deburring technologies<br />
and precision surface finishing, DeburringEXPO presents corresponding<br />
offerings in a concentrated fashion which is unparalleled<br />
by any other event.<br />
The bilingual expert forum and various theme parks will also ensure an<br />
effective transfer of knowledge at the 5 th leading trade fair at the Karlsruhe<br />
Exhibition Center October, 10 th to 12 th , <strong>2023</strong>.<br />
Ultrasonic deburring takes place in a water basin in which components<br />
are advanced to the high-frequency ultrasonic sonotrode<br />

The right process for every application<br />
“Thanks to its multi-industry, multi-material focus, DeburringEXPO supports<br />
companies from all industry sectors in their search for suitable processes,”<br />
reports Gitta Steinmann, project manager at private trade fair promoters<br />
fairXperts GmbH & Co. KG. “The entire spectrum of technologies,<br />
processes, tools and services for deburring, edge rounding, cleaning and<br />
surface finishing are presented. The strengths and the limits of various processes<br />
ranging from mechanical deburring with tools to vibratory grinding,<br />
brush deburring and blasting with solid and liquid media, right on up to ma-<br />
chining with special technologies, can be discussed<br />
directly on site.” The latter includes, for<br />
example, ultrasonic deburring which makes it<br />
possible to selectively deburr edges and crossdrilled<br />
holes in a fully automated, verifiable<br />
process. Since this energy-efficient process can<br />
be used for nearly any material, the range of<br />
workpieces covers everything from micro parts<br />
for the optics and watchmaking industries to<br />
precision tools for machining, all the way up<br />
to components used in machinery and vehicle<br />
manufacturing weighing 15 kg.<br />
Abrasive flow machining (AFM) also covers<br />
a very broad range of applications. It’s used<br />
for the deburring, edge rounding and polishing<br />
of components in the automotive and aviation<br />
industries, as well as in energy technology,<br />
fluid and medical engineering, extrusion<br />
technology and mould and tool making. The<br />
strengths of this process result from its ability<br />
to machine internal areas and surfaces which<br />
are difficult to access, for example in additively<br />
manufactured components.<br />
In the case of ECM (electrochemical machining),<br />
the machining process is based on<br />
the anodic dissolution of the respective metal.<br />
Nearly all metals can be machined, in particular<br />
high-alloy materials such as nickelbased<br />
and titanium alloys, and hardened materials.<br />
In addition to deburring, selective<br />
edge rounding and polishing, the technology<br />
is also used for contouring and shaping components,<br />
as well as for burr-free drilling – for<br />
example in the aviation and aerospace industry,<br />
the automotive and toolmaking sectors, in<br />
medical, microsystems and energy technology.<br />
Laser deburring is an effective method for<br />
removing fine burrs and flakes from the outer<br />
contours of very delicate, thin-walled workpieces.<br />
Even the edges of drill-holes with diameters<br />
of just a few tenths of a millimeter<br />
can be machined. The process is also distinguished<br />
by very high processing speeds.<br />
Thermal energy machining (TEM) permits<br />
the simultaneous removal of external<br />
and internal burrs by means of vaporisation.<br />
It’s used primarily for metal workpieces such<br />
as hydraulic manifolds, and for components<br />
made of thermoplastics from which internal<br />
and external burrs have to be removed – even<br />
from very difficult to access places.<br />

symposium<br />
news & facts<br />
VDW symposium<br />
attracted attention<br />
in Vietnam<br />
The VDW (German Machine Tool Builders’ Association),<br />
Frankfurt am Main, staged its third symposium<br />
in Vietnam’s capital Ho Chi Minh City June 12<br />
to 14, <strong>2023</strong>. Ten German manufacturers showcased<br />
innovations in manufacturing technology – machine<br />
tools from Germany.<br />
“The Vietnamese market has been enjoying very strong<br />
growth recently, and we are now the fifth-largest supplier<br />
here. And so it is only logical for our industry to return<br />
here in person to attract more attention,” says Gerda<br />
Kneifel, VDW ambassador at the symposium in Ho Chi<br />
Minh City. Ten German manufacturers were on hand at the<br />
event: Alzmetall Werkzeugmaschinenfabrik, Altenmarkt,<br />
the Chiron Group, Tuttlingen, Gleason Corporation,<br />
Ludwigsburg, Grob-Werke, Mindelheim, Maschinenfabrik<br />
Berthold Hermle, Gosheim, Index-Werke, Esslingen, Open<br />
Mind Technologies AG, Wessling, Röders GmbH, Soltau,<br />
Siemens AG, Munich, and the Trumpf Group, Ditzingen.<br />
They presented their latest machines, solutions and services<br />
for Vietnam. 121 participants from the most important<br />
customer industries– the electronics, textile and food industries<br />
as well as the metal production and processing sectors<br />
– accepted the invitation of the VDW and the German--<br />
Vietnamese Chamber of Foreign Trade. Being the best response<br />
since the first Vietnam symposia was held in 2016.<br />
“We need to raise the efficiency of our machines, and automation<br />
is a further very important aspect for us. The symposium<br />
gives us the opportunity to get in touch with German<br />
companies that offer high quality software solutions<br />
and that are very well organized,” says Cai Minh Giac, vice<br />
director of Phuvinh Technology Mechanical Ltd. from Ho<br />
Chi Minh City.<br />
Among the ASEAN countries, Vietnam has become an<br />
attractive industrial location and an important trading hub<br />
with increasing industrial production. The country is expanding<br />
its domestic production in order to manufacture<br />
higher-quality products, reduce costs and at the same<br />
time protect itself from international supply bottlenecks.<br />
It needs machine tools to achieve this. With a market volume<br />
of € 805 million, Vietnam is the 15 th largest machine<br />
tool market in the world. Nearly all of its demands is met by<br />
imports. Laser machines are on top of the required machine<br />
groups, followed by presses and lathes. However, the machine<br />
groups which are needed are constantly expanding.<br />
“Vietnamese imports are dominated by machinery from<br />
China, Korea, Japan and Germany,” explains Marko Walde,<br />
chief representative of the German-Vietnamese Chamber<br />
of Foreign Trade (AHK Vietnam). “German goods have<br />
an excellent reputation in Vietnam and are highly valued.<br />
And there are great opportunities for German exporters as<br />
a result of the strong demand in Vietnam, the modernization<br />
of production and the EVFTA free trade agreement.<br />
More than ever Vietnamese entrepreneurs accepted<br />
the invitation to the symposium<br />
source: AHK Vietnam<br />
Machinery imports totaled nearly $ 46.3 billion in 2021, 24.3 %<br />
higher than in 2020. The most popular types of machinery and<br />
equipment imported in 2021 included medical equipment and<br />
tools, followed by batteries, electrical switchgear and wireless<br />
telecommunications equipment.”<br />
German exports to Vietnam increased from € 12.9 million in<br />
2021 to € 19.5 million in 2022. The country thus rose from 47 th<br />
to 41 st place among the most important customer markets for<br />
German manufacturers. The Vietnamese market will remain<br />
attractive in the medium term.<br />

LACH DIAMANT – 100 Years<br />
Tradition. Passion. Innovation<br />
part 6:<br />
The start of CBN hard turning<br />
Turning instead of grinding<br />
Company founder Jakob Lach, 1894-1984<br />
(photo taken in 1980)<br />
Dear readers, in the last article<br />
(compare part 5: https://tinyurl.com/<br />
lachdiamant5), you could read about the<br />
introduction and beginnings of polycrystalline<br />
diamonds (PCD) for the superior<br />
cutting of aluminium and other nonferrous<br />
metals and composite materials;<br />
this happened – from today’s perspective<br />
– exactly 50 years ago.<br />
Today, I am taking you back to the<br />
events of 1974.<br />
I will begin with an anniversary, for once a<br />
personal occasion. On September 13 th , 1974,<br />
my father was celebrating his 80 th birthday<br />
with all his employees in the great hall of the<br />
“Kurhaus Wilhelmsbad” in Hanau.<br />
Even at this age, Jakob Lach was still the<br />
guarantor of good purchases of natural<br />
diamonds from global markets, mainly from<br />
Belgium, and, back in those years, natural<br />
diamonds were still much needed for diamond<br />
dressing tools and for turning tools.<br />
From my study of balance sheets in my possession,<br />
I could see that the sales of LACH<br />
DIAMANT® had more than doubled between<br />
1969 and 1974.<br />
Jakob Lach celebrated his birthday on a<br />
big scale with all his employees in the Kurhaus<br />
Wilhelmsbad in Hanau, but preferred to<br />
celebrate with the smaller group of his<br />
diamond cutters in his backyard.<br />

news & facts<br />
At this point in time, natural diamond tools<br />
were still the main sales and profit factor,<br />
followed closely by the massively emerging<br />
diamond and CBN Borazon® grinding wheels<br />
and polycrystalline diamond cutting tools under<br />
the name of dreborid® PCD.<br />
Back then, namely in 1972, my father took<br />
me on as a limited partner, and the sole proprietor<br />
company “Jakob Lach” became<br />
“Jakob Lach GmbH & Co. KG” – in short<br />
LACH DIAMANT®. The company expanded<br />
in size. The production of diamond and CBN<br />
grinding wheels had already taken on its own<br />
status, and was managed by Gerhard Iffland<br />
and Kurt Hemerka, and was located at the<br />
newly established factory 2 at Fasanerieweg in<br />
Hanau.<br />
The same applied to the expansively growing<br />
production of polycrystalline and natural<br />
diamond cutting tools at the main factory at<br />
Bruchköbeler Landstrasse 39-41 under Kurt<br />
Wagner (†), Gerhard Mai and technical engineer<br />
Günter Hobohm.<br />
Jakob Lach himself was ever-present as the<br />
much sought-after expert on natural diamonds.<br />
Advertising brochure for the Hanover spring tradeshow in 1975<br />
Back to 1974: as history tells us, the terracotta<br />
army of 7,000 life-sized figures was discovered<br />
in China; Hewlett Packard succeeded<br />
in making the HP65, the world’s first programmable<br />
pocket calculator; and the first<br />
VW Golf was launched on the market.<br />
Euphoria, ahead of time<br />
Back to LACH DIAMANT®: maybe, at<br />
least some of you will remember our slogan<br />
“Borazon® – Abrasive of a new Era” which was<br />
communicated in 1969, during our first presentation<br />
of a Borazon® CBN grinding wheel<br />
at the Hanover spring tradeshow. In part 5<br />
of this series you could already read about<br />
how my exuberant imagination played a trick<br />
on me. Due to my personal euphoria for the<br />
new abrasive Borazon® (Trademark General<br />
Electric), it was clear to me that GE’s announcement<br />
of a new abrasive could only be<br />
a Borazon®/CBN product. However, I was<br />
wrong. Instead of a cutting material made<br />
from CBN, much like Borazon®, GE surprised<br />
us in 1973 with the presentation of polycrystalline<br />
diamonds (PCD). Then we knew!<br />
A year later, in 1974, another surprise<br />
followed, and on top of that from an unexpected<br />
direction, that is to say, from Moscow.<br />
Via Hempel, at that time a company dealing<br />
with imports of silicon carbides, I was asked<br />
whether we had any interest in a synthetic<br />
Elbor CBN aggregate, sintered into a matrix<br />
product named “Elbor” for cutting metal. Apparently, they had become<br />
aware of LACH DIAMANT® because of our PCD activities. “Elbor, yes, of<br />
course,” if this should be the fulfilment of my wish for a “Borazon®” cutting<br />
material.<br />

I agreed to travel from East Berlin to Moscow.<br />
Product manager Kurt Wagner (†) and I landed<br />
in Moscow a few days before Christmas 1974.<br />
Ministers of the Soviet Food Department<br />
(apparently at that time responsible for the<br />
Russian diamond industry) welcomed us in a<br />
very friendly manner. A special highlight was<br />
an evening invitation to a “dacha”, far outside<br />
of the zone allowed for foreigners, as we<br />
were told with a wink. We had Vodka, and so<br />
many shots of it that my companion was feeling<br />
quite ill, despite his attempts to refuse it.<br />
According to the homepage of V-Bakul Institute for Superhard Materials, the<br />
facility was largely destroyed by the first missiles aimed at Kiev, shortly after the<br />
beginning of the war in Ukraine; shown here is a part of the institute’s premises<br />
Our “Elbor” business almost became a minor matter. The product was a<br />
pure pressed CBN body with a size of 0 8 x 6 mm. The delivery contract stipulated<br />
delivery exclusively via the company Hempel. At the end, we were invited<br />
to a “spontaneous” helicopter ride to Kiev in order to meet Professor<br />
Bakul from the “V-Bakul Institute for Superhard Materials”. For understandable<br />
reasons, we had to decline. It would have been interesting, that is for<br />
sure. Today, in <strong>2023</strong>, we could not make up for it; last year, the entire complex<br />
of the institute was destroyed by some of the first missiles on Kiev.<br />
Shopping adventures in Moscow<br />
Before our flight back, and thinking of the upcoming Christmas holiday, we<br />
went for a last shopping trip at Gum’s department store. We did not have<br />
much time. A very popular display of large Babuschkas (rag dolls) on the<br />
second floor caught our eyes. Each one of them like a “grandma with spectacles<br />
on her nose, and with a flowing big skirt.” “This might be something for<br />
our little ones.”<br />
This is how you can picture the doll<br />
purchased at Gum’s department store;<br />
45 cm large, meant for use as a coffee cosy<br />

We were caught in the order process, which, at this point, was still unknown<br />
and confusing to us. We communicated the order quantity with<br />
“hands and feet,” calculated the total on a wooden slide rule. We paid with<br />
our last remaining roubles, and we then had purchased about seven of the<br />
voluptuously large Babuschkas. No explanations from me about the further<br />
course of events… (Only this much: the above-mentioned dolls turned out to<br />
be coffee cosies.)<br />

At the Moscow airport lounge, we were already<br />
expected. “Unfortunately there would<br />
be a delay in our departure, the airport was<br />
blocked off. A big shot was expected: president<br />
of the state council, Willi Stoph.”<br />
Afterwards, during boarding into the tubeshaped<br />
Tupolev plane, our assistants prevented<br />
us from going into the normal coach area,<br />
and guided us towards the first-class seats.<br />
That was good (see photo, left side). Until the<br />
East German captain of Interflug asked us to<br />

Hours turn into minutes<br />
Back in Hanau, we started the new year of<br />
1975 with first preparations for the Hanover<br />
tradeshow in spring. What do we do with<br />
“Elbor”? Once again, chance came to our rescue,<br />
and, most significantly, via Borazon®:<br />
A “customer problem” occurred during the<br />
polishing of a metal-powder-coated cylinder.<br />
The customer found the grinding time with a<br />
CBN grinding wheel too long. “Well, we could<br />
try this compact CBN, this “Elbor” material.<br />
Thought, and done.<br />
Soldering, like with PCD, was unsuccessful<br />
without a solderable carbide carrier. Soldering<br />
in a vacuum was at that time no option,<br />
so the only alternative was to sinter the<br />
“Elbor” aggregate. Initially, the first attempt<br />
with a turning steel, made in such a way, was<br />
already successful. “This will be our tradeshow<br />
highlight; we will demonstrate it on a<br />
Weiler turning lathe.” And so, it happened<br />
at the Hanover spring tradeshow; the “new”<br />
product was successfully introduced under<br />
the name “dreborid®-G-AS“ for machining of<br />
metal-powder-coated turning parts. For the<br />
first time this resulted in minutes of turning<br />
time instead of hours of grinding time, and<br />
with almost polished surfaces. The first step<br />
toward better performance and efficiency during<br />
hard turning was made.<br />
Initially it was only a market niche for<br />
powder manufacturers who propagated the<br />
metal powder coating process – at that time<br />
especially Metco (today Oerlikon-Metco) and<br />
Castolin – for them, the dreborid®-G-AS turning<br />
tools were like a present.<br />
Their customers complained too much<br />
about high grinding times during the levelling<br />
of flame-sprayed turning parts, coated<br />
with alloys of nickel, chrome and tungsten<br />
carbide – no matter whether it was for repairs<br />
Hanover spring tradeshow in 1975 –<br />
first introduction of dreborid®-G CBN lathe tools for<br />
turning sprayed-on materials, HSS, cast and high-alloy hardened steel<br />
or wear protection. Turning instead of grinding immediately resulted in up<br />
to 90 % reductions in time. During this phase, Metco and Castolin provided<br />
repair kits (developed by us) to all their application technicians. The kits contained<br />
one dreborid®-G-AS turning tool and a specially designed dreborid®-<br />
G-Diamond grinding wheel.<br />
Due to CBN’s lower hardness, compared to PCD, it was possible to regrind<br />
cutting edges yourself, even with diamond grinding wheels.<br />
Encouraged by these first experiences, we let our search be guided for<br />
other possible applications by the positive experiences with the use of<br />
Borazon® CBN grinding wheels. In fact, both removal processes, grinding<br />

and turning, work well with materials of 58<br />
and 62 HRC, for example high-alloy hardened<br />
steel. We realised that from now on, there<br />
would be an increasing “gap” between grinding<br />
with CBN and machining with polycrystalline<br />
CBN cutting materials, independently<br />
from continuous attempts of the manufacturers<br />
of cutting tools to break this tendency with<br />
newly-developed carbide and ceramic types.<br />
The turning of high-alloy hardened steel<br />
was at that time purely experimental, especially<br />
because our initial fear was gradually<br />
confirmed. The composite body with 0 8 mm,<br />
delivered as “Elbor”, could only be used up<br />
to approximately 35 % when mounted to the<br />
holder with our chosen fastening; beyond<br />
that, the body would break out. What the<br />
CBN body was lacking for a stable connection,<br />
was a solid solderable carbide base, as known<br />
from polycrystalline diamond (PCD).<br />
Possibly alerted by our success with<br />
dreborid®-G-AS, the manufacturer General<br />
Electric informed us at the end of 1975 that<br />
they could now also offer polycrystalline CBN<br />
blanks but now, with CBN tightly connected,<br />
and with a solderable carbide base.<br />
Gaining Speed<br />
LACH CBN tools for turning and milling<br />
of high-alloy hardened steel, and known under<br />
the name dreborid®-G, could now gain<br />
further momentum. Each day brought new<br />
results and more satisfied customers, and it<br />
became part of the 100-year history of LACH<br />
DIAMANT®.<br />
However, we developed even further. Without<br />
the new buildings, a new office building<br />
and factory on the premises of Bruchköbeler<br />
Landstr. 41, and the large, rented facility at<br />
Fasanerieweg, we would have by far met our<br />
capacity limits, even back then. In addition,<br />
the turbulent developments in the area of<br />
polycrystalline cutting tools and in the production<br />
of diamond and CBN grinding wheels<br />
took their course far too quickly. By dynamically<br />
tackling the new technologies for grinding<br />
hardened steel (initially only offered by<br />
General Electric in 1969), Borazon®/CBN<br />
abrasive grits, and in 1973 also polycrystalline<br />
diamonds, the LACH DIAMANT® company<br />
had become like a pioneer and was now a constant<br />
factor in the market.<br />
In 1974/75, cutting tools under the name<br />
dreborid®-G were added to the portfolio, adver -<br />
tising to turn “hours of grinding into minutes<br />
of turning”, especially for super-hard abrasive<br />
materials. This was actually unbelievable!<br />
Dreborid-G-AS,<br />
used during the machining of metal-powder-coated wear components;<br />
hours of grinding time “turned” to minutes of turning time<br />
“Now, we can take our time and build on this,” my father and I thought.<br />
But, as already mentioned, the future held further developments for LACH<br />
DIAMANT®, all determined by sudden chances, courage and determination<br />
when seizing new and suddenly available opportunities…<br />
Yours, Horst Lach<br />

Burrless chamfering with world’s first V-shaped blade<br />
Nowadays, as the needs for environment friendly and value-added<br />
products increase, more parts are made lightweighted and highly functional.<br />
For this reason, increasing numbers of workpieces are lower in rigidity<br />
because of the complex shape, and difficult to cut because of enhanced<br />
strength. Therefore workpieces are increasingly more difficult to cut.<br />
Especially in medical and aircraft industries, additive (AM) is adopted to<br />
efficiently produce parts in complicated shapes.<br />
However, at mass production sites in the automobile industry, where<br />
monthly hundreds of thousands of vehicles are manufactured, use of 3D<br />
printers as replacement for metal molds is limited, because of costs and production<br />
speed reasons. Therefore the cutting process will remain essential in<br />
the future. When cutting the workpieces in mass production, increasingly<br />
difficulties can occur, opposing to small production, since in mass production<br />
stability is required.<br />
For example, when the rigidity of the workpiece is lowered, there may<br />
occur problems, such as vibrations, lowered surface roughness and change<br />
in size, affected by the change in machinability caused by a different lot,<br />
lowered tool sharpness by tool wear and changing cutting resistance. This<br />
uniformity in continuous machining can lower the process quality, leading<br />
to lowered workpiece quality.<br />
This not only applies to the size accuracy. When you think of the process<br />
of manufacturing a part throughout to the finish, it also affects deburring.<br />
Burrs formed in the cutting process can vary in size and shape because of the<br />
change in material and tool wear. There are<br />
different possibilities to remove burrs, which<br />
can cause instability in mass production.<br />
Production engineers are required to not<br />
only know the accurate size but also burr conditions,<br />
which is part of the product quality,<br />
and requires to take necessary measures to<br />
secure stability in mass production by equipment,<br />
jigs, tools and machining methods.<br />
Design specifications<br />
have an effect on<br />
the deburring process<br />
When a workpiece is cut, burrs will be formed<br />
only on the edges. Therefore it is important<br />
to know the requirements for the edges of<br />
a workpiece. To form “a sharp edge with all<br />
burrs removed”, cut the workpiece to form<br />
a sharp edge and remove all burrs in the deburring<br />
process. For “chamfering” and “round<br />
chamfering”, cutting and the removal of burrs<br />
takes place at the same time.<br />
When cutting the workpiece, secondary<br />
burrs can be formed. Although only slightly,<br />
these burrs formed by chamfering have to be<br />
removed.<br />
Aluminum component with semicircular contour on which the XEBEC<br />
Burrless Chamfering Cutter was tested. The flitter burr after pre-machining<br />
is clearly visible. Even the first test showed the full potential of the new<br />
chamfering cutter, because after the first pass there was no longer any<br />
burr to be seen (clearly visible in the close-up photos, right).<br />
The edge specification of “rounding range”<br />
is becoming popular. Rounding range means<br />
that the shape of the edge is not specified, and<br />
that it is possible to use a chamfering tool, or<br />
modify the edge shape in the deburring process<br />
after chamfering as long as it is within the<br />
range. Therefore, when the edge shape does<br />
not need to have a certain shape for a particular<br />
feature, such a specification allows various<br />
options for edge finish.<br />

processes<br />
The mode of action of the patented V-shaped cutting edge is decisive for the secondary burr-free end result. In principle, the<br />
process can be divided and illustrated in three stages: the outer area of the cutting edge shears off the top edge of the material and<br />
pushes the chip towards the center of the bevel. The inner part of the cutter is then used and pushes the chip upwards towards the<br />
center of the bevel. Finally, the chip is sheared off the workpiece at the center of the bevel and the tool leaves the point of contact<br />
with the workpiece. This procedure eliminates burr formation on the chamfered edge. Positioning accuracy is also improved<br />
by a flat tip that is resistant to rounding and chipping that would lead to measurement errors in tool length.<br />
Necessity of burrless chamfering<br />
Burrs are unwanted by-products formed by<br />
cutting tools in the process of shaping the<br />
parts. Ideally no burrs are formed in the cutting<br />
process. Most of the offered products are<br />
tools for the removal of burrs appearing on<br />
workpieces, filling the gap between ideal and<br />
reality.<br />
Since shaping the workpiece edges exactly<br />
is not possible, it is necessary to use a cutting<br />
tool for chamfering/round chamfering on the<br />
workpiece edges. By doing so again burrs will<br />
be formed on the chamfered edges. Therefore<br />
deburring is performed twice. The costs<br />
for performing edge finishing twice is not ignorable.<br />
Even if the process is automated, for<br />
example, to process 200,000 pieces per month! If it takes 5 seconds per piece<br />
to process, it takes 277 hours per month.<br />
Chamfering Features and Properties: chamfering is used to facilitate the<br />
assembly of parts and to prevent assembly problems that can occur due to<br />
overlapping part edges. In addition chamfering can prevent scratches and<br />
injuries during handling. What are the characteristics of roll chamfering?<br />
There are very few exact size requirements, although there are exceptions:<br />
for example, accuracy is unlikely to be affected by tool friction, but burrs<br />
formed during chamfering affect the rolls during chamfering.<br />
From this knowledge, XEBEC Technology was able to develop a burr-free<br />
Chamfering Cutter. The aim is to keep the burr size small; this results to an<br />
extension of the tool life, which is usually defined as being dependent from<br />
the burr size. It also eliminates the need for deburring after chamfering.<br />
If the current machining process includes deburring after chamfering, the<br />
deburring process can be eliminated, or the burr prevention effect can help<br />
to extend the tool life of the deburring tool. As a result, burrless chamfering<br />
can help to reduce idle time of machines, improving the productivity and<br />
reducing the costs.<br />
V-shaped blade mechanism<br />
Most Chamfering Cutters have straight blades. By using a cutter with a<br />
straight blade, poisson burrs which form orthogonally to the tool direction,<br />
can be formed on the upper and lower parts of the chamfered edge.<br />
Poisson burrs are formed because the workpiece material is pushed forward<br />
during cutting, and the material escapes orthogonally. The V-shaped blade<br />
developed by XEBEC is designed to make the plastic flow of the workpiece<br />
go toward the inside of the chamfering range, as to eliminate formations of<br />
poisson burr.<br />
A close-up of the patented cutting geometry<br />
with the V-shaped cutting edges. It took<br />
almost five years to develop this special shape,<br />
which offers clear advantages over straight<br />
cutting edges. Longer tool life, higher feed rates<br />
and no secondary burrs are guaranteed.<br />
If we now look at the test results with the V-shaped blade and the straight<br />
blade when chamfering workpieces made of different material, we can see<br />
that the V-shaped blade has a burr-preventing effect when chamfering different<br />
materials.<br />
For example, when deburring workpieces made of fibrous materials such<br />
as CFRP and woven Bakelite with the straight blade, the fibers remaining on<br />
the workpieces had to be removed manually. On the other hand, when the<br />
V-shaped blade was used to deburr the workpieces, no fibers were left on the<br />
edges and the surface layer was not removed.<br />
30 no.3, August <strong>2023</strong>
processes<br />
Another test took place on a quite complex stainless steel component. For experimental purposes, the burr formation was<br />
maximised during the preliminary work – but the burrless chamfering cutter also removed this hefty burr in one pass<br />
without leaving any residue and a uniform chamfer was applied.<br />
Preventing burr formation stabilizes<br />
mass production<br />
A test was conducted to determine the difference<br />
in tool life between the V-shaped cutter<br />
and the straight blade cutter by measuring<br />
the size of the burr. Both cutters were made of<br />
the same material and given the same coating.<br />
The machining parameters were as follows:<br />
workpiece material: stainless steel |<br />
speed: 6000min -1 | feed rate: 1200 mm/min<br />
Results and observations<br />
Tests indicate the burr size is correlated to the cutting distance, when using<br />
either the V-shaped blade or the straight blade cutters.<br />
Regarding the burrs on the upper edges, the difference is not significant<br />
at the beginning of cutting. But as the cutting distance advanced due to the<br />
blade wearing out, the burr size suddenly got bigger with the straight blade.<br />
Whereas with the V-shaped blade cutter the growth of burrs remained moderate.<br />
As a result there was a significant difference in burr size in the end.<br />
Regarding the burrs on the lower edges the difference in using different<br />
blades is significant, even from the beginning of cutting. Under the general<br />
standard of quality inspection, the tool life of the V-shaped blade is twice<br />
as long as that of the straight blade. From the results of several tests, it is<br />
verified that the V-shaped blade has the following effects<br />
■ prevents burr formation on workpieces made of various materials<br />
■ prevents the growth of burrs caused by the friction of the tool<br />
The quality of the workpiece is a target that can be achieved by fulfilling<br />
the requirements. However, in the cutting process, undesirable burrs are<br />
formed on the workpiece edges. Therefore, it is necessary to remove burrs<br />
after cutting to make the workpiece as close to as specified in the drawing. The<br />
appearance of each workpiece can vary when manually deburred. Even when<br />
the workpiece is deburred in an automated process, unwanted patterns or<br />
tool marks can emerge, depending on the used deburring tool.<br />

coating and on the far right the type 03N<br />
with stepped shank, three cutting edges<br />
but without coating.<br />
For the customer one of the requirements is the appearance of the workpiece.<br />
But it is not necessary to provide products that are overly excellent in<br />
appearance. However, the products vague in appearance can be regarded as<br />
uncertain in accuracy even when the accuracy is up to the standard. Burrs<br />
are formed on the edges of the workpieces. That means, securing the edge<br />
quality, which is an important matter in appearance inspection, is an important<br />
final touch to finish the product.<br />

Lightweight damper system for use in<br />
lightweight structures<br />
written by<br />
Thomas Götz and Ralf Müllner,<br />
Fraunhofer Institute for Manufacturing Engineering and Automation IPA<br />
Lightweight structures can offer productivity<br />
advantages, especially in highly dynamic applications<br />
such as machining technology, but they are significantly<br />
more susceptible to vibrations than solid structures.<br />
The research project “LeDALe” addresses this<br />
challenge and aims to develop weight-reduced damper<br />
systems for integration into lightweight structures,<br />
which will be tested on the applications chuck and cutting<br />
tool.<br />
In the context of modern, highly automated series production,<br />
machine and plant manufacturers are increasingly confronted<br />
with a trend towards shorter cycle times, greater<br />
diversity of variants and decreasing batch sizes. Meeting<br />
these demands requires the development of highly productive<br />
and flexible machine and plant concepts, which at the same<br />
time must be offered to the customer at a minimum price.<br />
Often these objectives go hand in hand with the need for a<br />
highly dynamic working speed of the machines, which in<br />
turn is significantly related to the weight of moving machine<br />
parts. A mass reduction of these machine parts leads to a<br />
more favourable machine dynamics and thus to an increase<br />
in productivity. Here, the use of modern lightweight materials<br />
and principles can make a decisive contribution and<br />
achieve concrete technological added value at simultaneously<br />
minimized costs. [1]<br />
However, machine structures in lightweight construction<br />
are often significantly more susceptible to vibrations com-<br />
pared to conventional solid construction due to their low<br />
system damping. Particularly in highly dynamic applications<br />
such as metal-cutting machines, these vibrations have<br />
a disruptive effect on the work process during operation. The<br />
results are high noise emissions, poor machining quality or,<br />
in extreme cases, even damage to the machine and its components<br />
due to high vibration amplitudes.<br />
The research project “LeDALe – Lightweight damper system<br />
for use in lightweight structures” addresses this challenge and<br />
aims at the development of weight-reduced damper systems<br />
for integration into lightweight constructions which are to be<br />
put into practice and validated in two common applications<br />
in the area of machinery and plant engineering, the chuck<br />
and cutting tool.<br />
Vibration phenomena in the machining process<br />
In the machining process, dynamic disturbances can occur<br />
in the form of different vibration phenomena (table 1). Basically,<br />
a distinction must be made between self-excited and<br />
[2, 3]<br />
externally excited vibrations.<br />
Externally excited vibrations are due to an external excitation<br />
force, which can occur either impulsively or periodically.<br />
The impulse excitation is caused, for example, by a fast axis<br />
movement or by cutting into material inhomogeneities. The<br />
externally excited vibration after a single excitation is characterised<br />
by the fact that the machine system with its natural<br />
externally excited vibrations<br />

frequency is set into vibrations, which decay exponentially<br />
[2, 3]<br />
due to the system damping.<br />
With periodic external excitation, however, the vibrational<br />
system is excited at the excitation frequency. In this context,<br />
examples include cutting engagement impacts during<br />
the milling process in which the machine structure<br />
connected via the milling tool resonates with the periodic<br />
excitation frequency. The closer this excitation frequency is<br />
to the machine’s natural frequency, the higher the amplitudes<br />
of the externally excited vibrations. The amplitudes reach<br />
their maximum when the excitation frequency coincides<br />
with the natural frequency of the machine, which is called<br />
[2, 3]<br />
resonance.<br />
Approaches<br />
In contrast, no external perturbing forces act on the machine<br />
system during the self-excited vibration. Instead, the<br />
vibrations result from the interaction between the cutting<br />
process and the connected machine structure. If, for example,<br />
the machine system is subjected to externally excited<br />
vibrations due to cutting edge entry, the vibration leaves a<br />
ripple on the workpiece surface. This ripple is particularly<br />
pronounced at vibration amplitudes in the resonance frequency<br />
of the machine due to its greater compliance for this<br />
frequency [3] . The chip thickness changes caused by the ripple<br />
in turn induce an increased vibration excitation of the machine<br />
in the natural frequency during chip removal by the<br />
subsequent tool cutting edge, which is referred to as the regenerative<br />
effect (figure 1). The self-excited vibration is thus<br />
a consequence of the surface ripple generated by the external<br />
[2, 3]<br />
excitation, which leads to greater process instability.<br />
to reduce vibrations<br />
Various methods are available to reduce vibration phenomena<br />
in the machining process.<br />
This includes, among other things, the decoupling of the<br />
excitation by the use of elastic intermediate components, the<br />
so-called insulating elements. However, decoupling close to<br />
the excitation in the force flow of the machine structure, e.g.<br />
at the tool holder or workpiece clamping device, is usually<br />
associated with high resilience and therefore can only be<br />
[2, 5]<br />
implemented with great restrictions.<br />
Another approach aims at changing the excitation frequency<br />
by selecting suitable cutting parameters so that it is<br />
no longer in the range of a dominant resonance frequency of<br />
the machine structure. However, this measure requires a certain<br />
amount of experience on the part of the operating personnel<br />
and often affects productivity, as it is usually necessary<br />
to deviate from the optimum process parameters. Thus,<br />
either the process time is extended when the parameters are<br />
reduced or the tool life is shortened when the parameters are<br />
[5, 6]<br />
increased.<br />
The withdrawal of the vibration energy can also be achieved<br />
via the principle of material damping. In this case, vibration<br />
energy can be converted into heat through the use of viscoelastic<br />
materials. Physical causes of this energy dissipation<br />
are, for example, sliding processes or microplastic deformations<br />
in the damping material. Currently, there are concepts<br />
of toolholders with integrated viscous dampers which have<br />
up to 90 % less dynamic compliance compared to undamped<br />

Cutting tool system with auxiliary mass damper [8]<br />
toolholders. However, these concepts require an increased<br />
static compliance of the tool clamping to allow higher deformations<br />
of the viscous dampers. The increased static compliance<br />
of the tool holder, however, results in a higher tool displacement<br />
and thus leads to dimensional and shape errors. [6]<br />
Principle of vibration absorber<br />
Another important method of damping vibrations is the<br />
principle of vibration absorber (figure 2, left), whereby the<br />
vibration is compensated for by means of additional masses.<br />
If a harmonic excitation with a certain frequency acts on<br />
a vibrating system, the system will vibrate with the same<br />
frequency. If an absorber mass is coupled to this system by<br />
means of a spring, the absorber executes oscillating movements<br />
in the opposite direction to the excitation, thereby<br />
withdrawing oscillation energy from the main system for its<br />
own oscillating movement. Provided, the absorber’s natural<br />
frequency is optimally tuned to the excitation frequency<br />
to be eliminated, the vibrations of the main system mass<br />
can be completely stopped, whereby two new pronounced<br />
resonance points are formed. However, this behaviour only<br />
occurs with ideal, i.e. pure spring coupling. Under real conditions,<br />
the spring-mass oscillator also has a damping component<br />
in the coupling and is called an auxiliary mass damper<br />
(figure 2, left). Although the vibration to be eliminated is not<br />
completely suppressed here, the new resonance points do not<br />
form as strongly.<br />
Contact<br />
Auxiliary mass dampers are already being used successfully<br />
by some cutting tool manufacturers for damping overlong<br />
cutting tools (figure 2, right) as well as long, slim extensions<br />
with large length-to-diameter<br />
[2, 5, 7, 8]<br />
ratios.<br />
surface damping and<br />
hydraulic expansion chuck<br />
An alternative to vibration absorbers is the contact surface<br />
damping, in which the vibration energy is converted into heat<br />
via a friction process (figure 3, left). In a first implementation<br />
of this principle on tool holders for long projecting rotating<br />
cutting tools, friction bars are used to reduce vibrations (figure<br />
3, right). A deformation of the basic structure leads to a<br />
relative movement between the prestressed friction bars and<br />
[6, 9]<br />
the basic structure, whereby a friction work is realised.<br />
Another application example in the field of contact surface<br />
damping is the hydraulic expansion chuck. In this system,<br />
by turning a clamping screw in the pressure chamber of the<br />
hydraulic system, a pressure is generated which leads to the<br />
elastic deformation of the expansion sleeve. The cutting tool<br />
located in the clamping sleeve is thereby clamped forcefully<br />
(clamping connection). In the process, the relative movements<br />
in the contact surfaces between cutting tool and<br />
clamp ing sleeve lead to friction, which contributes to vibration<br />
damping of the system. [10]<br />
All previously realized designs for contact surface damping<br />
are exclusively available in solid designs in order to support<br />
the normal force (clamping force) required to build up<br />
the frictional force.<br />
Summary and outlook<br />
With regard to the state of the art, it can be concluded that<br />
many successful approaches to increase damping in cutting<br />
tools and clamping devices already exist, which, however,<br />
require a high degree of competence in process control or are<br />
not designed for lightweight construction.<br />

For the development of low-mass damper systems, the<br />
principle of the friction damper appears to be principally<br />
well suited. In order to achieve the highest possible degree<br />
of lightweight construction, this damping approach is to be<br />
realised within the framework of “LeDALe” using a combination<br />
of various lightweight construction principles and manufacturing<br />
technologies. These include lightweight design,<br />
which aims to minimise weight by optimising shape and topology,<br />
whereby a constant stiffness of the damper structure<br />
is achieved with low material input. Another option is lightweight<br />
manufacturing, in which weight-saving potentials are<br />
realised through manufacturing and production processes,<br />
such as additive manufacturing methods. The third approach<br />
is lightweight material construction, which enables weight<br />
reduction through the use of lightweight materials such as<br />
fiber composites.<br />

Digital transformation in tooth machining<br />
Time-consuming and costly operations were the<br />
trigger for KAPP NILES to introduce digitalisation<br />
into its machining and support processes.<br />
Particular emphasis was placed on local integration,<br />
but at the same time on the possibility of interfaces in<br />
customer systems. This ensures easy installation and<br />
integration into the existing Industry 4.0 landscape.<br />
With the innovative software platform KN assist the<br />
company has succeeded in finding a practical solution.<br />
Take the set-up process to a new level<br />
Set-up processes are time-consuming and involve the risk of<br />
errors. Since tooling is often used in a multilayered manner,<br />
tracking of the machined workpieces or the clamping cycles<br />
is difficult.<br />
The Kapp Niles Tool Management with guided changeover<br />
sequences at the plant guides the employee step by step<br />
through the set-up process. Within the sequences, the query<br />
for identification takes place. The machine recognises whether<br />
the component is correct for the grinding project, so that the<br />
geometric and process-relevant information is transmitted<br />
to the control system. The KN extender displays all relevant<br />
data of the stored components in a local database outside the<br />
machine (see figure 1).<br />
The use and quality of tooling can be better planned via<br />
stored data, such as clamping and dressing cycles.<br />

Transparency in production<br />
Together with its customers, Kapp Niles has sought a way to<br />
transparently present the Overall Equipment Effectiveness<br />
(OEE) key figures on the machine and on mobile terminals.<br />
The aim is to visualise the relevant KPIs (Key Performance<br />
Indicators) clearly and easily.<br />
With the Kapp Niles Production Monitoring System designed<br />
in this way, all connected machines can be displayed<br />
in a dashboard. Two views can be selected (see figure 2).<br />
The machine overview shows the status of a machine. The<br />
individual machine view displays monitored status values,<br />
OEE key figures, relevant production data and the number<br />
of workpieces processed. The job history gives an overview<br />
of the most used grinding projects. The tooling dashboard<br />
is used in conjunction with the tool management system to<br />
visualise information about the tooling currently in use.<br />
The system also provides an overview of all pending service<br />
requests. New inquiries can also be triggered directly.<br />
André Wetz, product manager at Kapp Niles, describes<br />
further advantages of the Production Monitoring System.<br />
“OEE key figures become easy to access and visualise. The<br />
optimized presentation of the KPIs and the most frequently<br />
used grinding projects specifically show potential in the<br />
production process and environment. The device-independent<br />
access to all relevant production data enables a transparent<br />
display at any time and from anywhere. Reaction times<br />
can thereby be minimized. Optimized communication leads<br />
to faster problem resolution and thus to shorter machine<br />
downtimes.”<br />
Real-time monitoring of the machining process<br />
In order to meet the ever increasing quality requirements<br />
on the component and a high productivity, Kapp Niles has<br />
been looking for a solution for monitoring the grinding and<br />
dressing process. Here too, the company was in close contact<br />
with its customers in order to detect and avoid abnormalities<br />
already in the process. This avoids an expensive 100 % test<br />
afterwards.<br />
The Monitoring System analyses the grinding and dressing<br />
process. The tool state is monitored and an evaluation of ripples<br />
or orders on the component is carried out. Based on the<br />
analysed data, the machining process is determined and visualized<br />
at the HMI. Through adjustable limits, messages indicating<br />
deviations are issued at an early stage. An interface<br />
offers the possibility of providing data via a partial tracing to<br />
each manufactured workpiece. Data outside the machine can<br />
also be analysed in detail via export functions (see figure 3).<br />
Andreas Paatz, head of division service and tools at Kapp<br />
Niles, explains: “This system ensures a comprehensive examination<br />
of relevant features during the grinding and dressing<br />
process. As a result, errors or trends can be detected at an early<br />
stage and scrap and reworking percentage can be reduced. By<br />
monitoring the machining process, conclusions can also be<br />
drawn about the condition of the machine. A further advantage<br />
is that a removal of noisy workpieces after the machining<br />
process is made possible. By means of partial tracing, it is<br />
possible to detect critical workpieces also retroactively. Since<br />
the number of workpieces to be subsequently measured can<br />
be reduced, time and cost savings are achieved.”<br />

the adherence to deadlines, depending on the cause, and ultimately<br />
entail additional costs. The Condition Monitoring<br />
System monitors the wear condition of the linear and rotary<br />
axes of the processing machine. By means of specific reference<br />
runs, the condition is recorded during operation of the<br />
machine. The degree of wear of the axes is visually shown<br />
on the HMI of the machine. In addition to a forecast of the<br />
service life, pre-set limits are used to output trends on the<br />
machine. Interfaces for the transmission of relevant data to<br />
further customer-specific production systems are available.<br />
Furthermore the data can be supplied to each manufactured<br />
workpiece via a partial tracing. In analogy to the process<br />
monitoring system, the machine is equipped with additional<br />
sensors and a powerful IPC for evaluating the recorded data<br />
for monitoring the axes (see figure 4).<br />
Andreas Paatz: “The aim is to significantly reduce unplanned<br />
machine downtimes. This allows better planning of maintenance<br />
intervals and prevents unnecessary or premature<br />
replacement of machine components. This is due to the fact<br />
that fewer wear parts have to be kept in stock and can be ordered<br />
on a condition-based basis. The trend in modern production<br />
plants is towards condition-oriented maintenance<br />
and repair. Kapp Niles offers a powerful product here.”<br />
Make maintenance transparent<br />
Unforeseen maintenance work makes life difficult. Unpredictable<br />
production downtime can lead to reduced productivity<br />
and increased costs. If maintenance is necessary, missing<br />
information leads to additional expenditure.<br />
The Maintenance Manager displays all maintenance plans<br />
and instructions in digital form. The database provides complete<br />
maintenance management with triggers, consumables,<br />
time expenditures, responsibilities and priorities. This enables<br />
usage-based maintenance. A traffic light function indicates<br />
when maintenance is due. All activities carried out are<br />
stored in the asset archive.<br />
This archive (see figure 5) is used to support the planning of<br />
maintenance processes.<br />

Efficient machining by everyone<br />
The new OSP-P500 control is equipped with the “Digital Twin” to speed up the<br />
production processes and reduce preparation times. It facilitates high-precision<br />
simulations of the machining processes: with “Digital Twin on Machine” this<br />
simulation takes place on the machine itself, so that machining can be started<br />
immediately afterwards. Simulation can also be done with “Digital Twin on<br />
PC” on a computer to prevent downtimes, allowing the machine to be used for<br />
other machining processes. Even inexperienced users benefit from all the advantages<br />
of the CNC control thanks to the exceptionally user-friendly interface.<br />
The “Smart OSP Operation” function simplifies handling and provides automatic<br />
guidance through all the necessary steps, meaning that people without<br />
any prior experience can learn how to machine a workpiece in a single day.<br />
The OSP-P500 is also ideally equipped for high-speed machining with high<br />
surface quality: thanks to “Smart Control”, it has twice the computing power<br />
of conventional machine controls. This significantly shortens reaction times so<br />
that the cycle times can be reduced by up to 15 %.<br />
Smart technology for greater energy efficiency<br />
Thanks to the integrated “Eco Suite Plus”, the new OSP-P500 meets all customer<br />
requirements of reducing the power consumption. The smart features record<br />
and analyses every operating status and CO₂ emissions, switch to energy-saving<br />
idling if required and automatically adjust peripherals, such as the chip conveyor<br />
or suction. In future Okuma will gradually launch a range of new Green<br />
Smart Machines. These intelligent machine tools are particularly designed for<br />
the reduction of CO₂ emissions with reduced energy consumption, while still<br />
ensuring the highest quality. The OSP-P500 is also part of the package.<br />

From watchmaker to precision manufacturer<br />
Opening new industries with a<br />
Kern Micro HD around the globe<br />
High precision manufacturing is the basis of every<br />
successful watchmaker. So why not use this knowledge<br />
for other industries? That’s what Nicholas Hacko<br />
thought. After founding “Nicholas Hacko Watchmaker”<br />
(NHW) in Sydney in 2011, he launched another company,<br />
NH Micro, in 2020. Here he works for many parallel<br />
precision industries – from medical technology to<br />
aerospace. Investments in the best five-axis milling<br />
technology – most recently in a Kern Micro HD – were<br />
decisive for his success.<br />
Nicholas and Josh Hacko are thrilled about their<br />
Kern Micro HD: “With the experience we have gained so far,<br />
we believe that this manufacturing center will pay for itself<br />
in less than five years, despite the high investment costs”<br />
Watchmaking and high-precision engineering are in the<br />
Hacko’s blood. When Nicholas Hacko emigrated from Europe<br />
to Australia in 1992, he was already working in the industry<br />
as a third-generation watchmaker. Since his son Josh was also<br />
learning the profession, he decided to start his own brand in<br />
2011 – NHW. The focus of NHW was to become an independent<br />
watchmaker in Australia, manufacturing high quality<br />
timepieces.<br />
Being aware that the highest quality requires the highest<br />
precision – and that this cannot be achieved without the best<br />
manufacturing technology – the small company invested in a<br />
used Kern Pyramid Nano five-axis machining center in 2017.<br />
Nicholas Hacko remembers: “It was a big investment for us.<br />
But it paid off extremely quickly. The machine reliably mills<br />
tiny parts like gears, bridges, mainplates, levers and other<br />
small parts with the highest level of accuracy, with very high<br />
efficiency.”<br />
The parts from NH Micro require manufacturing accuracies<br />
in the micrometer range and surfaces up to Ra ≤15 nm<br />
Internal watch production grew quickly and within 5 years<br />
NHW had released 5 models. This rapid growth begged the<br />
question: which other industries – beside the watchmaking<br />
industry – require unique parts manufactured with such high<br />
precision? Nicholas and Josh Hacko concluded that medical<br />
technology and aerospace companies, for example, would<br />
have great demands as growing markets. So it would be obvious<br />
to use existing knowledge and capacities and expand the<br />
field. Could, should, would. It was necessary to overcome the<br />
subjunctive and act.<br />

machining center<br />
Rocket start with his job shop<br />
That’s exactly what the Hacko’s did for the first time at the<br />
end of 2018. “Our first non-watchmaking-industry part was<br />
for a Formula 1 racing team,” says Nicholas Hacko. “We were<br />
commissioned to produce sample parts. These were never<br />
used in serial production, but our client was satisfied and that<br />
was an eye-opener for us. We suddenly saw the enormous<br />
field of precision parts applications.”<br />
Orders from medical technology, mold-making and scientific<br />
instrumentation companies followed a short time later,<br />
and the business picked up speed. The watchmaker founded<br />
a second company called NH Micro in 2020. News of the<br />
high quality of Hacko precision parts spread quickly, causing<br />
sales to double from 2020 to 2021, even despite the Covid<br />
crisis. Accordingly the capacities of the Kern Pyramid Nano<br />
soon reached its limits. Nicholas Hacko asked his Kern advisor,<br />
Udo Reinwald, Kern Asia pacific director at the beginning<br />
of 2021 which solution he would recommend. With the<br />
rapid development and potential future of the two NH operations<br />
in mind, he suggested the world’s best five-axis machine<br />
for high-precision machining, the Kern Micro HD.<br />
Investing in the world’s best five-axis machine<br />
for high precision<br />
Nicholas Hacko was just as enthusiastic about this machining<br />
center as his son Josh. They recognized the potential and<br />
made a rather conservative ROI calculation. Josh Hacko explains:<br />
“It was a big investment for our small company with<br />
nine employees. However, seeing the potential that would be<br />
enabled with the new machining center, it should have paid<br />
for itself in around five years, our decision was quickly made,<br />
and we ordered the Kern Micro HD.”<br />
The machine was put into operation in March 2022. With<br />
full order books the Kern Micro HD now runs every day –<br />
without any problems. And their range of customers keeps<br />
growing. To name just a few examples: in addition to prototypes<br />
and small series’ of up to 500 pieces for medical technology,<br />
orders for opto-mechanical and microfluidic components<br />
are increasing, as well as for rocket propulsion nozzles,<br />
fiber optic connectors and dosing pump components.<br />
“There hasn’t been a part for which our Micro HD hasn't<br />
achieved the required accuracy,” says Nicholas Hacko happily,<br />
explaining the main requirements placed on his operation:<br />
“For our internal watch production, manufacturing accuracies<br />
of around five micrometers is quite common. But every<br />
now and then there are parts where bore positions and diameters<br />
with tolerances down to +/- 2 µm must be maintained.”<br />
This is no problem for the Kern Micro HD. If required, it also<br />
achieves precision of less than 1 µm in serial production.<br />
When it comes to surface quality, NHW and NH Micro<br />
also have very high standards. When processing different<br />
steels you need Ra values of ≤ 20 nm and, in some cases,<br />
Ra ≤ 15 nm for non-ferrous materials. Hacko says: “We achieve<br />
this reliably. However, I believe that even better values would<br />
be possible if required.” He is right, as Reinwald confirms:<br />
“With the Micro HD we can also achieve Ra values in the<br />
single-digit nanometer range.<br />
The Kern Micro HD is easy to operate and has extremely fast<br />
linear motors, resulting in very high processing speeds<br />
NH Micro, Sydney (Australia), …<br />
…was founded in 2020 by Nicholas Hacko. He started<br />
his own watchmaking company in 2011 (NHW), which<br />
has been producing up to 80 % of its watch components<br />
in-house since 2016. In 2018 Hacko began to work as a<br />
contract manufacturer, supplying precision parts to<br />
companies in other industries. Today the two small<br />
companies NHW and NH Micro employ nine people.<br />

Shown here is an internal automation package within the tool changing cabinet;<br />
up to 210 slots are available in the tool changer of the Kern Micro HD, enabling NH Micro<br />
to manufacture a wide range of different precision parts without having to change tools<br />
There is almost no temperature influence<br />
There are a few technological highlights, unique even for a<br />
precision machining center, that are decisive for accuracy.<br />
The Micro HD used by NH Micro has a sophisticated temperature<br />
management system that is unique to the market.<br />
With this special solution, the Kern Micro HD remains within<br />
a temperature range of +/- 50 mK even under extreme<br />
conditions. This is crucial because – according to recent research<br />
– temperature influences are responsible for around<br />
70 % of all accuracy errors in the high-precision area.<br />
Another advantage is in the large-scale and actively temperature-controlled<br />
linear motors. Compared to ball screw<br />
drives, they bring clear advantages in terms of dynamics<br />
and control accuracy and achieve rapid traverse speeds of<br />
60 m/min. Nicholas Hacko says: “This keeps our non-productive<br />
times very low. We are working much more efficiently<br />
than would be possible with other machines.”<br />
The owners of NH Micro – Nicholas and Josh Hacko – have<br />
precision in their blood, but they also regularly prove this<br />
with high-quality measurement technology<br />
The many technical refinements of the Kern Micro HD<br />
and their high quality, together with their ever-growing<br />
order book, make the Hacko’s optimistic for the future. The<br />
two companies are growing steadily, so that after 2021 their<br />
sales doubled again in 2022 – despite the difficult global<br />
situation. In addition to the Australian market orders from<br />
Europe and the USA are now also increasing. Accordingly<br />
Nicholas Hacko is even more relaxed about his latest investment<br />
today: “Based on the experience we have gained, I believe<br />
that it will take us less than five years for the Kern Micro<br />
HD to pay for itself.”<br />

A partnership for an automated future<br />
components<br />
At automatica <strong>2023</strong> (Munich) SCHUNK exhibited<br />
smart new developments that enable handling tasks to<br />
be solved transparently, flexibly and reliably.<br />
Making its customers’ processes understandable, simple and<br />
efficient is the declared goal of automation specialist SCHUNK.<br />
Data transparency plays an important role here. It enables reliable<br />
processes and provides the basis for resource-efficient<br />
planning, zero-defect production and energy efficiency. The<br />
digitalization of components and processes go hand-in-hand<br />
with sustainable manufacturing. It was shown how digital solutions<br />
lead to greater efficiency and lower resource consumption<br />
with practical examples from automated production in a<br />
wide field of applications.<br />
In focus: transparent processes<br />
SCHUNK showed a whole range of new products that contribute<br />
to a boost in efficiency. Among other things the PPD<br />
positioning unit made its debut, enabling more complex motion<br />
sequences in pneumatic handling. In conjunction with<br />
pneumatic grippers, gripper fingers can be controlled flexibly<br />
and with high precision, and gripping force and speed can be<br />
regulated. Required application parameters for defined gripper<br />
series are already stored on the unit – this saves time during<br />
commissioning. Combined with the power ful, pneumatic<br />
universal gripper PGL-plus-P with an extra-long stroke, versatile<br />
handling tasks can be realized even in demanding environments,<br />
from machine loading to highly sensitive cleanroom<br />
applications. As the first in the world the company offers<br />
the pneumatic gripper with a certified, secure GripGuard<br />
gripping force maintenance. It has an already integrated IO-<br />
Link sensor system that enables position sensing of the gripper<br />
fingers and thus saves on external sensors.<br />
Flexible from batch size 1<br />
Two new electric grippers set standards in terms of flexibi lity,<br />
interface diversity, and process reliability: the smart universal<br />
gripper EGU shows its strengths to the full in multi-variant<br />
machine loading, even under harsh conditions. With its large<br />
stroke and integrated gripping force retention it is able to<br />
reliably load and unload raw and finished parts of different<br />
sizes. It can be freely networked. The integrated gripping<br />
force maintenance and a StrongGrip mode for increased gripping<br />
force makes it an all-rounder for all handling tasks. Its<br />
counterpart for handling delicate, fragile parts in cleanroom<br />
areas is the smart EGK gripper for small components. With<br />
its SoftGrip mode it masters demanding and varied handling<br />
tasks in the laboratory industry or electronics manufacturing.<br />
Both grippers are offered with extensive function modules<br />
and commissioning plug-ins.<br />
Easy entry into intelligent handling<br />
For handling individual objects the user-friendly 2D Grasping<br />
Kit has been developed, randomly arranged on a single<br />
level, which makes it much easier to get started with automated<br />
object handling. The core of this intelligent system is<br />
SCHUNK presented a new generation of linear direct drive axes<br />
with the SLD series and therefore ensures short cycle times<br />
and more productivity<br />
the in-house developed AI software, which is pre-installed<br />
on SCHUNK’s own industrial PC (SVC). Since the market<br />
launch in 2022 the automation expert has further optimized<br />
the software and simplified the teaching and labeling of components.<br />
This coordinated complete package of hardware, soft<br />
ware and service comes from one source and can be used for<br />
all robots.<br />
Power through direct drive<br />
The first time presented dynamic linear direct axes SLD can<br />
handle higher load capacities, due to the profiled rail guide<br />
and compact design, having a long service life. With heavyduty<br />
axes equipped with electric linear direct drive, users<br />
achieve increased productivity in high-speed assembly and<br />
handling processes due to the short cycle times.<br />
The new flat ERT rotary units are also equipped with direct<br />
drive and offer a wide range of measuring system interfaces<br />
such as the HIPERFACE DSL® digital real-time interface and<br />
an electric holding brake. The unit can be used as a rotary<br />
table for components, assembly groups and tools, or as a rotary<br />
module in gantry solutions, as a rotary indexing table or a<br />
precise positioning module.<br />
Your partner when switching over to automation<br />
In order to successfully counter the shortage of skilled workers<br />
and pressure for efficiency and to accompany the change<br />
to digital, more sustainable manufacturing processes, the<br />
application expert offers a variety of automation approaches<br />
from a single source. The company demonstrates automation<br />
solutions for new, easy-to-integrate manufacturing<br />
and assembly processes that meet the requirements for precision,<br />
dynamics and reliability in different industries such as<br />
e-mobility and life science.<br />

When precision is of the essence<br />
The CNC dividing heads of the HOFMANN RWNC<br />
series have been known for their high precision since<br />
they were first launched. This is made possible through<br />
Rodriguez components that are used in the bearings of<br />
the dividing spindles. With new applications requiring<br />
even greater precision, the partners jointly developed<br />
an alternative solution: special high-precision bearings<br />
can meet the ambitious requirements.<br />
Hofmann is a well-known supplier of key components for the<br />
machine tool industry. The company manufactures all major<br />
components for dividing and rotary movements in its own<br />
modern manufacturing facilities. It focuses on tailor-made<br />
solutions that are impossible to achieve with standard solutions<br />
from other manufacturers. In addition to dividing units<br />
and rotary tables, the product range also comprises a wide<br />
range of coordinated accessories, including tailstocks and<br />
counter-supports for bracing long workpieces.<br />
Included in this range is the RWNC single-axis NC dividing<br />
unit, which is suitable for use with both vertical and horizontal<br />
rotary axes. The standard tip heights of the RWNC series<br />
are 75, 100, 125, 160, 220, 300, 380 and 400 mm. Special<br />
tip heights can be achieved by using bases or adapted housings.<br />
The hydraulic clamp of the dividing spindle enables<br />
high machining forces to be applied. It is also possible to use<br />
indirect or direct position measuring systems.<br />
Excellent radial and axial run-out<br />
as a unique selling proposition<br />
“The CNC dividers in the HOFMANN RWNC series are primarily<br />
distinguished by their mature, robust and stable design”,<br />
says Timo Conzelmann, head of design at Hofmann.<br />
“Coupled with exceedingly high accuracy values, the customer<br />
receives a reliable solution that is individually tailored<br />
to the respective application scenario.” The dividing heads<br />
are used primarily as a 4th axis on machining stations and<br />
on engraving, grinding or measuring machines. They feature<br />
a stable, vibration-free design and also stand the test of rough<br />
working conditions thanks to their robust construction.<br />
The Rodriguez rotary table bearings (RTB) are now<br />
also available in an HSA version<br />

The Rodriguez components used in the bearings of the<br />
dividing spindles all contribute to the high precision of the<br />
CNC dividing units<br />
image: Werkzeugsysteme Müller GmbH<br />
The eccentrically adjustable worm drive of the dividing<br />
heads consists of a case-carburised worm shaft and a worm<br />
gear made of an extremely low-wear bronze alloy. Coupled<br />
with a high performance lubricant, it runs with very little<br />
fric tion and backlash, thus also consuming very little power<br />
compared to torque drives. “What is particularly noteworthy<br />
is the high level of accuracy”, emphasises Timo Conzelmann.<br />
“The outstanding radial and axial runout on the dividing<br />
spindle is due in part to the Rodriguez bearings.”<br />
New requirements for accuracy<br />
Up to now the drives of the dividing heads used a fourpoint<br />
Rodriguez bearing as the radial thrust bearing, whereas<br />
the tilting moment was supported on a radial ball bearing.<br />
This combination has proven itself over many years – but<br />
now there was a wish to achieve even higher levels of accuracy,<br />
which could not be achieved using the previous bearing<br />
arrangement.<br />
“Our dividing heads are used, among other things, for<br />
thread measurement in measuring machines”, explains Timo<br />
Conzelmann. “The workpiece is clamped between fixed tips<br />
in the dividing unit and tailstock.” For this the dividing unit<br />
is equipped with an optional dividing spindle with an Mk-2<br />
Morse taper. This application requires an elevated radial and<br />
axial run-out in the Morse taper of less than 0.006 mm – for<br />
comparison: Until now a maximum of 0.01 mm was the rule.<br />
In concrete terms, the specification given to Rodriguez was:<br />
the new version would have to achieve a runout of 0.005 mm<br />
in the Morse taper and on the gauging mandrel and a runout<br />
of 0.0025 mm on the dividing spindle face.<br />
Precise, very precise, high-precision bearings<br />
“In close cooperation with the customer we developed a new<br />
solution tailored to the new requirement profile”, explains<br />
Ulrich Schroth, key account manager for VAP at Rodriguez.<br />
44 no. 3, August <strong>2023</strong>
components<br />
“The dividing spindle is now supported in a spindle bearing<br />
arranged in an O arrangement in each case and held in place<br />
with a shaft nut.” The customer grinds the inside of the Mk-2<br />
Morse taper of the dividing spindle in its assembled state on<br />
the grinding machine driven by the dividing unit itself. This<br />
puts accuracy within this range.<br />
The dividing heads now use high-precision bearings from<br />
SKF’s “Super Precision Bearings” series, which Rodriguez has<br />
had in its range since 2020. These high-precision (axial) angular<br />
contact ball and cylindrical roller bearings are specially<br />
designed for the tough requirements of machine tools. They<br />
not only support high rotational speeds and payloads, but<br />
also run as stiffly and extremely accurately as possible and,<br />
last but not least, generate little heat and low levels of noise<br />
and vibration. They also have an impressively long service<br />
life, long maintenance intervals and low energy consumption.<br />
Large range of bearings for the machine tool sector<br />
“The high-precision bearings enable original equipment<br />
manufacturers and end users to further optimise the parameters<br />
of their systems and applications”, says Ulrich Schroth.<br />
“This can be very well demonstrated by the present application”.<br />
In the field of machine tools, the bearing arrangement<br />
of spindles and rotary or indexing tables is important for<br />
optimum force absorption and transmission. Thanks to its<br />
comprehensive range of precision rolling bearings, Rodriguez<br />
can optimally meet all requirements.<br />
High precision in use is usually of utmost importance.<br />
Bearing manufacturers are still making improvements in<br />
this respect. A further example of this are the Rodriguez rotary<br />
table bearing series (RTB), which have been available in<br />
a new version for some time. These high-precision solutions<br />
are particularly suitable for positioning rotary or indexing tables<br />
in machining stations. Now they are also available in an<br />
HSA version, which offers impressive stiffness, requires 20 %<br />
less starting and running torque and offers a 20 % increase in<br />
speed. Users also benefit from up to 70 % more moment rigidity<br />
and load capacity (both axial and radial). These significant<br />
improvements were achieved, among other things, through<br />
re-dimensioning of the RTB bearings by the manufacturer<br />
and an optimised production process.<br />
Breaking new ground<br />
together with the customer<br />
“In this case improved models and new software enabled a<br />
more accurate calculation”, concludes Ulrich Schroth. “Tests<br />
and developments in cooperation with selected customers<br />
also generated valuable experience and greater expertise in<br />
this field. I think that especially the latter is extremely important,<br />
beyond any trends: working out solutions that the market<br />
really needs, jointly with the customer.” This has always<br />
been Rodriguez’s philosophy – which is also reflected in the<br />
new version of the HOFMANN dividing head.<br />

New CAM software will drastically improve the way<br />
manufacturers operate their Laser machines<br />
GF Machining Solutions has launched a new version<br />
of a computer-aided manufacturing (CAM) software,<br />
LaserCAM, part of the LaserSUITE360 software package.<br />
At the EPHJ tradeshow in Geneva (Switzerland), GF Machining<br />
Solutions has introduced the new advanced software LaserCAM.<br />
LaserCAM, included in the LaserSUITE360 1.13.0<br />
software package, offers operators a completely new user<br />
inter face for creating and editing laser engraving and decoration<br />
designs easily. It provides improved calculation speeds,<br />
reducing the time required for programming and setup,<br />
Example of a micromachining application shown in LaserCAM<br />
and enables manufacturers to respond to changing production<br />
needs quickly and get their products faster to market.<br />
It is specifically designed for laser engraving, micromachining<br />
and decoration operations, with over a decade of experience<br />
in the field and promising to drastically improve the way<br />
manufacturers operate their laser machines. This will allow<br />
manufacturers in watchmaking who have been hesitant to do<br />
so to adopt laser machining for their applications.<br />
In addition to its existing engraving tools, LaserCAM includes<br />
unique features such as 3D finishing, blasting and<br />
watchmaking decoration functions, allowing manufacturers<br />
to create intricate and precise designs. The software has been<br />
developed with a novel modular architecture, which is a significant<br />
leap forward in user-friendliness. GF Machining<br />
Solutions will be able to expand the features in the coming<br />
versions, aiming to consolidate its leading position in micro<br />
cavity, semiconductor and hard material machining as well as<br />
watchmaking applications. LaserCAM is compatible with the<br />
entire range of GF Machining Solutions’ Laser ablation machines<br />
to meet the specific needs of every manufacturer.<br />

High level of innovation with<br />
six-sided complete machining<br />
Anyone using EMO as an opportunity<br />
to discover any kind of innovation for<br />
their company will find satisfaction with<br />
the CHIRON Group.<br />
If one is familiar with the world of six-sided<br />
complete machining with milling and turning,<br />
one knows about the benefits when machining<br />
highly precise, complex and thus often very expensive workpieces. Even the<br />
very first produced part must have the correct dimensions. The MT 715 two+<br />
and the FZ 08 S mill turn precision+ stand up to these demanding requirements<br />
at the fair. The machining centers will show why the six-sided complete<br />
machining system with integrated automation always means a productivity<br />
boost for customers.<br />
Micro5: the number one in micro-machining<br />
In a very short amount of time, the smallest and most energy-efficient machine<br />
from the CHIRON Group has become a bestseller. The USPs of the<br />
Micro5 are sustainable and ultraprecise, with an energy requirement of just<br />
0.5 kW/h, size of under 1 m 2 and micron-level precision. Together with the<br />
automation Feed5, the Micro5 features high autonomy. With a workpiece<br />
blank of 50 x 50 x 3 mm (capacity of over 1,200 blanks) and an assumed cycle<br />
time of 10 min, that equates to eight days of automated production.<br />

Powerful and productive<br />
New 5-axis machining center F 6000 from HELLER<br />
At EMO <strong>2023</strong> HELLER will present the new generation<br />
of its F 6000 machining center for the first time.<br />
The 5-axis machine with head kinematics was designed<br />
from the ground up for flexible series production.<br />
Like all HELLER machines, it sets a benchmark for cutting<br />
performance and precision, including free chip fall, short<br />
idle times, optimum automation capability and compatibility<br />
with the H and FP series for a wide range of workpieces. The<br />
F 6000 also scores with first-class equipment and expandability<br />
with technologies such as mill-turn, interpolation turning<br />
or power skiving. The team led by HELLER’s head of development,<br />
Dr. Manuel Gerst, kept a close eye on these topics, as<br />
well as consistent standardisation and the use of key components<br />
‘Made by HELLER’.<br />
Highlights of the new generation include the completely<br />
redesigned swivel heads and the new integrated motor spindles<br />
specially developed by HELLER. The spindle units deliver<br />
the highest levels of precision, dynamics and cutting performance<br />
for 5-axis machining.<br />
For combined milling and turning operations, the machine<br />
is equipped with the optional Mill-Turn function, in which<br />
the high-torque DDT (Direct Drive Turning) rotary table<br />
plays a key role. In line with the trend towards complete machining<br />
this eliminates the need for reclamping on separate<br />
turning machines. The results are improved workpiece accuracy<br />
and significantly reduced cycle times, especially for series<br />
products. The pallet changer is included as standard as<br />
the first level of automation. The new ‘Automation ready’ option<br />
enables easy integration of the HELLER rotary pallet<br />
storage (RSP) and HELLER’s standardised linear magazine<br />
solutions at a later date.<br />
HELLER will present for the first time the new generation<br />
of its F 6000 machining center<br />
For maximising in day-to-day production, HELLER’s design<br />
engineers have focused on clear and easy operation as<br />
well as good accessibility to all work areas. The new Siemens<br />
SINUMERIK ONE control fitted as standard and the convenient<br />
control unit in panel design with 24” touch screen make<br />
operation easy. At the same time, increased access to the<br />
work area and the optional new SETUP-Assist make it easier<br />
to set up processes on the machine.<br />
At the heart of HELLER’s trade show appearance will be<br />
360° performance – a holistic view of the requirements of<br />
modern production. To achieve this, HELLER focuses on five<br />
solution areas. In addition to the F 6000, HELLER will be<br />
presenting products for the digitisation of production, a comprehensive<br />
range of services as well as innovative manufacturing<br />
processes and technologies for complete machining on<br />
a single machine.<br />

Meeting complex challenges with smart solutions<br />
At EMO Schwäbische Werkzeugmaschinen GmbH<br />
(SW) will present two new products: the two-spindle<br />
BA W03-22 CNC machining center and the BA profile,<br />
a new machine concept for machining profiles.<br />
Furthermore, SW will be showing the BA space3, currently<br />
its largest machine for machining battery housings, and will<br />
be offering insights into current trends in manufacturing<br />
such as friction stir welding and giga casting.<br />
“Innovate Manufacturing” is the theme of this year’s EMO,<br />
which also captures the very essence of SW’s “Smart Manufacturing<br />
Solutions” corporate claim. “For us innovative and<br />
smart manufacturing are two sides of the same coin,” says<br />
André Harter, head of marketing and business development<br />
at SW. “Both allow us to respond individually and efficiently<br />
to our customers’ needs. At EMO Hannover we also want to<br />
reinforce our ‘Be smart. Be part’ theme. This applies not only<br />
to sustainability, which we are driving forward at SW with<br />
our ECO2 machining programme. It also applies to our technology<br />
people. They are at the heart of our vision and our<br />
smart solutions.” The market leader for multi-spindle machines<br />
will be exhibiting three machines from its extensive<br />
range of smart manufacturing solutions, two of them for the<br />
first time.<br />
Efficiency boost for the automotive industry<br />
Productivity, flexibility, modularity, and connectivity: these<br />
are the most important factors for SW when it comes to<br />
meeting challenges with efficient system solutions in the<br />
fast-growing field of e-mobility. Case in point is the new<br />
BA W03-22 CNC machining center. Thanks to its high precision<br />
and efficiency, this two-spindle machine is ideal for producing<br />
high-quality workpieces in medium and large series<br />
for the automotive industry. Compared to a single-spindle<br />
machine, cycle times can be reduced many times over, ensuring<br />
maximum productivity. “We have expanded the<br />
Smart Manufacturing Solutions from SW offer increased<br />
productivity, flexibility, modularity and connectivity<br />
proven machine concept of the model 3 series to include a<br />
two-spindle, double-station machine. It allows for faster axis<br />
accelerations with the linear motors installed in the machine,”<br />
explains Harter. “As a result we achieve more power and<br />
speed compared to a ball screw as in the BA 322 model, for<br />
example with 20 % faster chip-to-chip times.” With 300 mm<br />
of travel, the BA W03-22 also positions in G0 30 % faster than<br />
the BA 322. The machine is the first from SW to be equipped<br />
with Siemens Sinumerik One control.<br />
Flexible machining with BA profile and BA space3<br />
Another highlight is the new BA profile. Featuring a compact<br />
design, the two-spindle machine has two operating areas and<br />
allows machining on two worktables per side. It can be loaded<br />
either via automation or ergonomically by hand.<br />

Precise, process-reliable and efficient milling<br />
URMA AG is expanding its precision tool range<br />
with the diamond-tipped MX diamond shoulder<br />
and face shell mill tool, which is suitable for machining<br />
light metals such as aluminum. Here, too, URMA<br />
relies on the patented quick-change system, which<br />
promises the best handling and maximum precision.<br />
MX diamond is available in three different diameters:<br />
63 mm, 100 mm and 125 mm<br />
sion tool systems that are used worldwide in the mechanical<br />
engineering, automotive, hydraulics and aviation industries.<br />
The market for light metal workpieces and their machining<br />
tools is constantly growing. The use of known shoulder<br />
and face mill tools works, but the handling is complex and<br />
time-consuming. The company has applied its vast experience<br />
in the application of high-precision quick-change cut-off<br />
points. The result: MX diamond is a completely new shoulder<br />
and face shell mill system. With this modular cutting tool,<br />
URMA relies on the proven and highly precise RX quickchange<br />
cut-off point, which guarantees perfect axial run-out<br />
without needing subsequent correction when changing cutting<br />
edges. The teeth of the solid carbide cutting edge body<br />
are fitted with up to 20 PCD (polycrystalline diamond) tips<br />
and are ideally suited for machining lightweight materials<br />
such as aluminum, magnesium, copper-containing metals<br />
without iron, composites and fiber-reinforced plastics. This<br />
latest generation of face milling ensures lean production processes<br />
and automated production. Thanks to the high tool rigidity<br />
of the MX diamond, both finishing and roughing cuts<br />
can be made with the same cutting edge. With a feed rate of<br />

EDM wire machines from € 3 / hour operating costs<br />
Ageltech GmbH is a manufacturer<br />
and supplier of electro-erosion machines<br />
and CNC diamond wire saws with an<br />
outstanding price-performance ratio.<br />
The EDM machine supplier also has a M-series<br />
in its range, spark erosion wire machines<br />
based on molybdenum wire technology. The<br />
simple and clearly designed machines feature<br />
outstanding operating costs from less than<br />
€ 3 / hour incl. depreciation and amortization<br />
over 5 years with € 25 k acquisitions costs. Molybdenum wire technology is<br />
little known in Europe, but all the more so in Asia. Well over half of the wire<br />
erosion machines there work with molybdenum wire technology. In general<br />
this technology is suitable for cutting conductive materials, e.g. from the<br />
usual large vehicle parts (also made of aluminum) to tools made of steel (including<br />
carbide steel) to small medical products made of special alloys.<br />
Ageltech offers very affordable entry-level machines with manual wire<br />
threading. It is most advantageous for works with either long, continuous<br />
eroding or where the eroding path can be eroded briefly into the workpiece<br />
from the outside, i.e. without a starting hole. Cutting contour accuracies up<br />
to +/- 10 µm and roughness up to Ra 0.8 µm display the impressive quality<br />
possibilities.<br />
The molybdenum wire technology achieves cost advantages mainly<br />
through the multiple reuses of the wire. It is rolled up and down during the<br />
process. This can be done for several working shifts with the same wire, with<br />
one winding usually being just under 200 m.<br />
Another source of the cost advantage is the simple rinsing of the wire with<br />
a water-based antioxidant agent instead of the usual technology in an immersion<br />
bath. The workpiece remains in the air and only the sparking area<br />
being machined is flushed. The whole handling is easy and machines are<br />
available from R&D applications to industrial mass production.<br />
The M-series is available in many sizes from working areas of<br />
320 x 450 x 200(h) mm³ up to 1,300 x 1,900 x 500(h) mm³. Special sizes on<br />

EMO<br />
Highest precision with extra technology<br />
At EMO <strong>2023</strong> Kern introduces for the<br />
first time the advanced five-axis machining<br />
center Kern Micro HD with a new<br />
Fischer CSC spindle and high-end control<br />
Heidenhain TNC 7. Furthermore<br />
visitors can engage with Kern Micro<br />
HD and with the laser machining center<br />
Kern Femto E3.<br />
Visitors will see three precision machines.<br />
Among the precision machines, they can also<br />
find many individual innovations, with which<br />
the Kern Micro HD can be equipped in the<br />
future. Just one example: the highly effective<br />
shaft cooling of the new CSC HSK 40 spindle<br />
reduces the previously required warm-up<br />
time to almost zero.<br />
The company’s experts and advisors will be explaining the resulting opportunities<br />
for applications as well as the technical background of all displayed<br />
parts. Visitors can look forward to experiencing the Kern Micro HD,<br />
which was launched in 2020 and is now very popular with more than 150 installed<br />
machines worldwide. Eight different sample parts in different materials<br />
will be machined. Extremely hard and softer metals as well as ceramics<br />
and graphite. The machining center proves its versatility and reliability when<br />
it comes to precision and surface quality in the µm area.<br />
As a third machine Kern Microtechnik will present the laser machining<br />
center Kern Femto E3. It will machines in regular intervals heading tools for<br />
cutting inserts. The advantage of laser machining is the lack of tool costs and<br />
the stability of the process, while achieving accuracies of +/-3 µm and surface<br />
qualities of Ra = 0,1 µm. Other applications for this technology are for example<br />
surface texturing and applications in mold & die.<br />

Small differences that make a big impact<br />
Oerlikon Balzers, a leading global<br />
technology brand of the Oerlikon Group,<br />
will showcase its latest high-tech surface<br />
solutions at EMO. The S3p coating<br />
BALIQ TISINOS PRO for hard machining<br />
up to 70 HRC will be shown for the<br />
first time, while other highlights include<br />
the carbon coating BALINIT MAYURA,<br />
the diamond coatings from the BALDIA<br />
family and advanced digital production<br />
and connectivity technologies.<br />
Products and services from the sister brands<br />
Oerlikon Metco and Oerlikon AM complete<br />
the trade fair line-up, where the theme is<br />
“Small difference, big impact”.<br />
In a milling test, the innovative<br />
BALIQ TISINOS PRO coating achieved up to<br />
50 % longer service life than its predecessor<br />
Improved performance in machining hardened and stainless<br />
steels and high-temperature alloys<br />
BALIQ TISINOS PRO, the latest coating innovation from Oerlikon Balzers,<br />
clearly demonstrates how small differences can have a big impact. BALIQ<br />
coatings are based on the S3p (Scalable Pulsed Power Plasma) coating technology,<br />
which combines the advantages of arc evaporation and magnetron<br />
sputtering processes to push the boundaries of conventional HiPIMS coating<br />
performance. The microstructure and smoothness of BALIQ TISINOS PRO<br />
have been further enhanced, resulting in even better wear resistance. When<br />
machining high-temperature alloys and stainless and hardened steels up to a<br />
hardness of 70 HRC, the AlTiSiN coating withstands high thermal loads and<br />
ensures an even more stable process. Tests with end mills have shown an average<br />
increase in tool service life of up to 50 % compared to its predecessor<br />
coating with higher production quality, particularly in micro-machining.<br />
Carbon and diamond coatings for non-ferrous metals,<br />
lightweight construction and more<br />
Introduced in 2022, BALINIT MAYURA is attracting increasing attention,<br />
and not just because of its rainbow color. The thin and extremely hard<br />
ta-C coating for machining non-ferrous materials such as aluminum, copper,<br />
brass alloys and polymers minimizes material build-up on the tool while<br />
maintaining extremely sharp cutting edges. High precision, longer tool service<br />
life and increased productivity are the reasons why toolmakers and end<br />
users are increasingly turning to BALINIT MAYURA.<br />
The BALDIA family from the company serves innovative markets such as<br />
the dental, automotive, and aerospace sectors but also traditional industries<br />
like mold making. These CVD diamond coatings are ideal for the highly<br />
abrasive machining of graphite, ceramics or CFRP/GFRP materials, supporting<br />
sustainable manufacturing solutions in electromobility and lightweight<br />
construction. For example, BALDIA COMPOSITE DC has tripled the tool<br />
service life of CFRP drills in aircraft construction while reducing tool costs<br />
by more than half.<br />

Manufacture more parts faster<br />
The skilled labor shortage, disruptions<br />
in supply chains and rising costs for mate -<br />
rials and energy are affecting manufacturing<br />
companies involved in machining.<br />
That is why industry is searching for ways<br />
to improve efficiency and flexibility in<br />
order to manufacture more parts faster,<br />
resulting in that more machines need to<br />
be operated by fewer employees.<br />
This solution is reinforced by increasing automation<br />
with pallet changers or handling<br />
A CAD/CAM process helps to program complex<br />
machine tools with multiple spindles, tool<br />
carriers or units: here, parting off the workpiece<br />
and transferring it to the second spindle<br />
systems. Machining centers need to be operated unattended, so that employees<br />
can manage these tasks. The machine needs an NC program that covers<br />
all operations, from the setup of a blank and provision of the required tools<br />
to removal of the part. This NC program has to be complete and error-free.<br />
Achieving this goal requires digitalization and automation before the machine:<br />
i.e., before machining. If all the tasks are prepared in advance in the<br />
virtual world using precise digital twins, there won’t be any surprises during<br />
machining. For example, if the programmer has a precise digital model<br />
of the planned setup situation and the machine and works with digital<br />
twins of the machining tools, including precise geometric data and cutting<br />
data tested in practice, the result is an NC program that already fulfills most<br />
of the above requirements. A subsequent complete simulation in the CAD/<br />
CAM environment provides the final safety element for all traverse movements<br />
and limit switches. This is also ensured by output via a postprocessor<br />
that’s been certified by the CAD/CAM provider. This delivers complete NC<br />
programs with sequences for turning, milling, drilling and even measurement<br />
integrated in the process.<br />
Fast NC programming with automated rules in a knowledge base<br />
Modern automated machining centers have a high part throughput and<br />
therefore require a large volume of NC programs. This means that the NC<br />
programming process needs to be automated, by compiling the company’s<br />
manufacturing knowledge, saving it and making it available in automated<br />
rules in a knowledge base.<br />

EMO<br />
Adjustable damped boring bar<br />
Long tool overhangs can cause a turning tool to oscillate<br />
when boring internal geometries. In addition<br />
to the resulting chatter marks on the surface, these vibrations<br />
also lead to a significant reduction in tool life.<br />
For unfavourable length/diameter ratios, the experienced<br />
machinist relies on vibration-damping boring<br />
bars, which enable low-vibration machining but which<br />
can still vibrate during certain machining operations.<br />
Paul Horn GmbH has addressed this problem and is presenting<br />
a boring bar at EMO in Hannover that can be adjusted to<br />
the vibration amplitudes that occur. Precise adjustment of the<br />
damping element in the boring bar enables a vibration-free<br />
grooving process. This results in better surface quality without<br />
chatter marks and a significant increase in tool life.<br />
The exact adjustment of the damper, made of a carbide rod<br />
supported in O-rings, is made from the outside via an adjustment<br />
screw. Adjustment is achieved by fine-tuning the pretension<br />
of the O-rings. This allows the boring bar to be precisely<br />
set according to the vibration occurring in each application.<br />
As standard Horn offers the tools from stock in<br />
the length/diameter ratios 5 x 0 and 8 x 0. Higher ratios are<br />
possible as special tools. For the grooving processes, Horn offers<br />
the S224 double-edged grooving system. The Horn cassette<br />
system BK 224 ensures a stable interface between the<br />
boring bar and the inserts. To further increase process reliability,<br />
the boring bars are equipped with an internal coolant<br />
supply.<br />

EMO<br />
Mechatronic solutions for metal working<br />
When it comes to international competition,<br />
there ary many challenges for<br />
European manufacturing companies<br />
nowadays. However with the careful use<br />
of digitisation, including artificial intelligence<br />
in combination with robotics and<br />
other automation solutions, it’s possible<br />
to make significant leaps in productivity to guarantee increasingly<br />
stable competitiveness.<br />
This is where the mechatronic solutions developed by HSD come into play.<br />
In fact, EMO will be an unmissable opportunity to get an exclusive preview<br />
of the new ES1020 and ES1040 electrospindle models, developed by HSD to<br />
complement the ES10 Line. The result of technological advancement and<br />
continuous collaboration between our engineering team and our customers,<br />
based on their requirements, these new electrospindle models are able to<br />
adapt to the multiple needs of users and the ever’-increasing pace sought by<br />
today’s market.<br />
In line with the future trends of digitisation and Industry 4.0, HSD will<br />
present a preview of a special “connecting device” which, from now on, can be<br />
installed on the range of electrospindles dedicated to metalworking, allowing<br />
them to be connected to the myHSD IoT platform via a series of sensors.<br />
The connecting device developed by HSD therefore follows the leit motiv<br />
of the event, helping to “innovate manufacturing” and making production<br />
processes more efficient and effective, increasing productivity and quality<br />
while minimising errors and machine downtime.<br />

New standards in the machining of<br />
profile plates and shank tools<br />
Schütte’s 105linear five-axis grinding<br />
machine reduces the setup effort for machining<br />
profile plates and shank tools to<br />
a minimum.<br />
When it comes to grinding cutting tools such<br />
as drills, milling cutters and profile plates,<br />
the proportion of small batch sizes through<br />
to single-part production is increasing. At the<br />
same time demands on shape and dimensional<br />
accuracy and resulting surface qualities<br />
are increasing. In this context, contour tolerances<br />
in the lower micrometer range must be<br />
maintained during grinding, which means<br />
that ideally the first part is also directly a good<br />
part. The bigger the batch size, the more likely<br />
it is that a set-up effort will be tolerated due to an iterative correction of the<br />
grinding result. Especially in the case of single-part production, however,<br />
this setup effort must be reduced to a minimum. The Schütte 105linear offers<br />
the highest first part accuracy, but is also optimally suited for series products<br />
due to its high process reliability.<br />
Highest accuracy with only one measuring process<br />
Also the application area of profile plates deserves special attention. Unlike<br />
cylindrical cutting tools (especially drills/mills/cutting punches), the clamping<br />
of these workpieces is already highly interesting. The nail clamping technique<br />
is a proven, reliable and productive solution for positioning profile inserts<br />
for grinding in the machine and also for machining multi-bladed inserts<br />
over the entire circumference. It is also here important to achieve the<br />
highest accuracies, so the subsequent contact surfaces of the indexable insert<br />
in the toolholder can be measured individually and the grinding contour automatically<br />
adapted to it. This guarantees that in the final use of the workpiece,<br />
no further measurement is required when indexing the insert again –<br />
even for the highest quality demands. The 105linear series is also suited for<br />
this workpiece category because high grinding feeds can be carried out with<br />
the highest precision, which offers an immense productivity advantage.<br />
Simple and fast measurement through automation<br />
Already during process preparation, the machine as well as the robot and the<br />
grinding wheel handling are automatically measured. That’s easier and faster<br />
than manual measurement, and the machine operator can then devote himself<br />
to more important tasks.<br />
