Milling cutter innovations
aid high speed machining
Sandvik Coromant tooling concepts speed through milling operations
Tool developments aimed at higher performance in high
speed machining (HSM) have been ongoing for several
years now with good results identified in many different
applications. HSM developments during the 1990s, for example,
looked at the total concept, including building machine
tools capable of 200,000 rpm as institutions demonstrated the
consequences and risks involved with such high velocities, when
tools or machine parts were not suitable for the applications in
question. The main factors to be considered were cutting forces,
surface finish, metal removal rate, tool life and safety.
Milling aluminium dies
Today, secure insert retention is a priority when it comes to HSM
and indexable insert tools. High spindle speeds and table feeds,
especially when machining aluminium, introduce high centrifugal
forces and consequently large loads on insert retention elements.
Using finite element analysis to develop an optimized
cutting tool solution, Sandvik Coromant has introduced a new
generation of HSM tool for aluminium alloy machining – the
CoroMill® 790 indexable insert milling cutter.
CoroMill 790 has been developed for operations involving pocketing,
edge machining, slotting and profiling – many of which
appear in die and mould making. Insert retention is provided
through a specially developed insert-to-holder interface that enhances
the quality of the machined workpiece and also improves
machining capability through a more even load on the inserts.
Indexable solid carbide tooling
Indexable insert endmills are made in diameters down to 12
mm, below which handling and clamping of inserts becomes
unpractical. Solid carbide endmills on the other hand have diameters
of tenths of a millimetre. The tool diameter range of 10
to 25 mm is one that is inhabited by both types of endmills. It

TECHNOLOGY TODAY
...continued from page 3
is here that Sandvik Coromant exchangeable head (EH) endmills
come into their own, capturing the benefits of both cutter types.
The heart of the EH cutter CoroMill 316 is the coupling between
the tool head and cutter body. One of the most vital parts of the
coupling is its self-centring screw with a patented thread designed
A selection of CoroMill 316 inserts and EH holders
to pull and hold the head into the shank and leave no hint of play.
CoroMill 316 has axial tool length repeatability and radial run-out
limited to within a few hundredths of a millimetre.
Insert grade for higher speed
To achieve higher machining security at elevated cutting data,
wear resistance needs to be prioritized over toughness. Consequently,
the move to a harder ISO P20 insert grade should be
considered for steel dies. To improve machining further, steel die
milling should be performed without coolant. Dry milling is preferred
because today’s high machining rates make it hard for even
high amounts of coolant to have much effect at the cutting edge.
Most of it is vapourized and the rest only serves to cool the insert
intermittently as it goes in and out of cut. In this way, thermal
variations are amplified, which proves more detrimental to the
insert than high temperatures.
High speeds and feeds mean more heat. But with a steel milling insert
grade like GC4220 this is not a negative factor. GC4220 is an
ISO P20, CVD-coated grade designed to perform at higher cutting
data. Some operations have productivity as a higher priority than
versatility and thus require more wear resistance, perhaps also to
cope with harder steels. Thermally-related wear mechanisms then
become far more prominent issues and need a grade that can
resist this type of edge breakdown. GC4220 has been developed
as first choice for reducing machining times through higher
speeds – broad enough to be an optimizer for many steel die
materials as well as a complementary choice for cast iron
milling where heat is also an issue.
Facing up to the challenge
The trend in many die and mould shops is for higher feed rates and
smaller depths of cut (after roughing). This is kind to the machine
and enhances results. Power limitation is also a growing factor in
4 www.SMTCL.ca SEPTEMBER 2011
ISO taper 40 and 30 machining centres. The higher speeds and
feeds of today’s machines also mean that machining shoulders and
faces through repeated passes with smaller diameter milling cutters
can be more efficient.
These factors helped to set the direction for a new generation of
square-shoulder facemill. Consequently, it was found that a suitable
maximum depth of cut for the first of a new platform of milling
cutters, CoroMill 490, should be at the lower end: 5.5 mm, with 4
mm being the recommended value. This also provided the scope
for equipping the new facemill with square inserts, a basis for high
insert stability through precise and secure insert locations as well
as good tool economy.
CoroMill 490 Milling Cutters
In conclusion, HSM milling has been elevated in performance
thanks to various cutting tool developments that are now being
exploited by progressive machine shops all around the world, operating
across many different sectors.

SMTCL - changing the way
you look at machine tools
from mainland China
For years many of us only considered machine tools from
Mainland China for mostly manual machining operations.
When we were challenged with more sophisticated work,
it was only the machines manufactured by the more familiar
machine tool builders that we considered. Many of us assumed
Mainland China only started building machine tools fairly
recently - say within the past 30 to 50 years.
You might be surprised to hear that Shenyang Machine Tools,
or SMTCL, started manufacturing machine tools over 100 years
ago and for quite some time, had a long - range plan to market
their machinery worldwide. To improve their knowledge base,
SMTCL seized the opportunity to purchase SCHIESS GmbH, a
German heavy-duty machine tool builder, which has 150 years
of history. This was the beginning of building a market leader
that some day could compete with the other major machine tool
builders at an international level.
Predictably, SMTCL began to work with their new German partners
on the development of a major line of sophisticated, large
format machine tools. It might surprise you that some of the
advanced machine tools you purchased from well know builders

NEW
GMC2590u Gantry-Style 5-Axis
Vertical Machining Center
in Europe, were manufactured under contract by SMTCL.
SMTCL products can be divided into two categories - CNC machine
tools, including: CNC lathe, CNC milling-boring machine, vertical
machining center, horizontal machining center, gantry type machining
center etc.; and the second group: conventional machine
tools, including conventional lathe, radial drilling machine, horizontal
boring machine and multi-axis automatic lathe.
SMTCL machines are available in over 300 varieties and with
a thousand available specifications, thus enabling the Company
to satisfy any of your precision machining requirements
- cutting, knurling and milling, or boring, drilling, and turning.
Currently, SMTCL products are extensively utilized in scores of
industries, such as automotive, national defense and military,
aerospace and aviation, railway transportation, and much more.
The recent China International Machine Tool Show successfully
showcased 1,222 exhibitors from 28 countries in over 110,000
square meters of exhibit space, making it the fourth largest machine
tool exhibition in the world. The show, which had attendance
exceeding 265,600 visitors, featured most of the major

machine tool builders worldwide.
One of the most dominant exhibitors
was SMTCL - and for a very good
reason. They unveiled their largest
introduction of new models at
any show in the Company’s history.
Exhibitors were astounded to see
new models on the SMTCL booth
that were engineered and built to
compete with most major builders
throughout North American and
Europe. “We were expected to introduce
very competitive CNC machine
tools in the large capacity category”,
says Katherine Fong, Branch Manager, SMTCL Canada. “However,
many show goers were astounded to see the advancements
we have made in all other categories of machine tools”.
The new SMTCL VMC series is designed to be the workhorse
of the small to medium range of the vertical machining center
category. Its basic structure is designed using finite element
analysis, and its casting utilizes the latest modern casting technology
to produce a machine that will hold its rigidity and accuracy
and reduce vibration under all machining conditions. It
is available in a wide range of configurations including designs
for educational environments (E-series), typical machine shop
requirements (B-series), and finally, machine tools for high-
performance applications.
The FBC (Floor-Type) and PBC (Table-Type, Tee-Configuration)
series of CNC horizontal boring, drilling, and milling machines
come in a near-endless variety of configurations that can be
pre-specified by the user, and then custom-built to that spec.
TECHNOLOGY TODAY
Different options of spindle
diameters, ram sections, travels
in any axis, tool-changers,
coolant configurations, control
options, table capacities, chip
removal, etc., make the FBC
and PBC series adaptable to
any user requirements.
The HTM series of CNC horizontal
slant-bed lathes can incorporate
additional machining
axes for single setup part
production that will save the
user time and money. With C
and Y-axis options, milling operations can be performed in addition
to turning to minimize the time required to make complex
parts. The same state-of-the-art manufacturing principles that are
utilized in all the other types of machines are equally employed at
SMTCL, for long-lasting accuracy and performance.
The ETC series of CNC lathes utilizes the relatively economical
flatbed construction, while providing a slant-carriage for
improved cutting geometry and chip evacuation. It is the best of
both worlds for the discerning manufacturer who is constrained
by budgetary limitations.
All manufacturing at SMTCL incorporates the latest machine
tool design and casting technologies, and the assembly and
fit are done in some of the most clean and advanced facilities
available anywhere in the world. All CNC machines are
equipped with name brand controls, while major wear components
are also name brand so years from now, if they require
replacement, they can be sourced locally anywhere in the world.
SMTCL to Exhibit at CMTS 2011 - Booth 2526
In concert with the worldwide launch in China, SMTCL plans a
major introduction of machine tools in their BOOTH #2526
at the Direct Energy Centre in Toronto, October 17-20, 2011.
On their booth they will feature the following machines:

raises the bar
for the gear
manufacturing
industry
In most manufacturing sectors involving machining, we see
declining markets and investments. Large manufacturers are
either disappearing or are the victims of a takeover by competitors
or other large companies. Company history is no longer
a prerequisite for success – today’s market just wants to know
what can you guarantee to do for me today.
Havlik International truly stands apart from many of today’s
trends. They have exceptional company history – the company
started in the 1880’s in the Czech Republic and then relocat-
8 www.SMTCL.ca SEPTEMBER 2011
ed to Canada in the mid 1940’s. Today, the company is still
run by one of the original family members – fourth generation
John Havlik Jr.
Havlik International has two core business units – large
gear manufacturing and they are also a major distributor of
machine tools, representing major machine tool manufacturers
like TOS, CDK Blansko, Kovosivit Mas, Tos Kurim, Skoda,
and Trens from their homeland Czech Republic, and of course
SMTCL from China.

“Large gear manufacturing is a very competitive market”, comments
John Havlik Jr. “There are less than 10 large gear manufacturers
in North America and only two in Canada. Havlik Gear
is by far the largest manufacturer of large gears in Canada and,
everyone in this market competes head to head within North
America and in many international markets.”
Large gear manufacturers experienced similar challenges as
their smaller counterparts
but with a few
exceptions. Large gear
manufactures also must
make heavy investments
to be competitive; they
have exceptionally challenging
production
demands; and lead
times for product could
take years rather than
months. Customers in
the large gear market
want better accuracy,
excellent service, and
obviously extended life
on gears.
When we talk about
large gears, we are talking
upwards of six to
eight meters. The large
gear market has met the
same challenges as other
market segments during
the past recession.
“In 2008, we manufactured
twenty-five large
ring gears,” says Havlik,
“but in 2009, we
only manufactured five.
This is partially due to
a declining market and
also likely to a demand
for improved quality.
We recognized this early
and in the past 18
months we made some
significant investments
to dramatically improve
our production quality
and shorten lead times.
Although customers for
large gears are accustomed to waiting longer for product, requirements
for lead times on tenders have been getting shorter
for some time now.”
Havlik Gear recently purchased the SMTCL GTC 450140 CNC
vertical lathe for all turning operations on large gear blanks or
large hubs and pinions for gears on wind turbines. Havlik manu-
factures the internal gears for the gearbox, which increases the
speed from the blades that turn slow on the windmill. They also
manufacture the gears that turn the head of the windmill and
the gears that turn the pitch of the blades.
The machine has a table diameter of 157 inches and 1- 60 rpm
in two ranges of table rotation with 100 kW of continuous power
with 65,307 ft. lbs of torque. For Havlik’s application, SMTCL
modified the base machine.
The standard
swing has been modified
from 177 inches
to 196 inches. The
work piece height is
56 inches, and the
machine’s maximum
work piece weight is
20 tons. The hydraulically
counterbalanced
ram has a large cross-
section of 240 x 240

Koss Aerospace
A Canadian success story with the
contribution of MTS workholding systems
When founder Drago Cajic started Koss Aerospace in
1975, aerospace component manufacturing relied
heavily on the skill and knowledge of the machinist.
Thirty-six years later, that enhanced knowledge continues to
be the core of Koss’s business. Koss, located in Mississauga,
Ontario is still one of the aerospace industry’s leading manufacturers
of machined components and sub-assemblies. Koss
Aerospace is a fully integrated, Lean Manufacturing operation,
utilizing the latest in machine tool technology and CAD/CAM
software. To maintain their competitive edge, Koss Aerospace
has also achieved AS/EN/JISQ 9001 Rev B and ISO 9001:2008
status; as well as providing NADCAP Chemical Processing, Heat
Treatment, and NDT & Surface Enhancement support services.
The Koss facility was designed and built in 2006 for maximum
workflow and efficiency. “From the beginning”, says Cajic. “Everything
in our building was designed for efficiency and flexibility.
The electrical and all other services have been installed
to permit us to change the plant layout and workflow to suit the

Obviously the backbone of the Company is machine tools and Koss
Aerospace only invests in machine tools with value added capabilities.
“Our machining centers, for example”, says David Cajic, VP of
Strategic Management, “have three, four or five axes capabilities,
equipped with pallet changers for maximum productivity. To maximize
the efficiency of their machine tools, Koss has also invested
in the most advanced software for programming their machine
tools. “We have the latest versions of MasterCAM, Virtual Gibbs
and PowerMILL”, says Cajic.
Integral to the efficiency of the machine tool technology is standardizing
our workholding strategy. “When we were asked by Cajic
to recommend a simple, but highly adaptable solution”, says Lino
Libertella of Machine Tool Solutions. “After analyzing KOSS work
environment and manufacturing needs, we recommended the Lang
MAKRO-GRIP® center vise and the QUICK POINT zero point system.
It is adaptable for almost any machining application, and it is
particularly effective for use on pallet table and tombstone applications
for multi-axis or automated machining. The advantage of the
MAKRO-GRIP technology is its high clamping force capability and
repeatability, with a minimum actuation force. It also has a large
clamping range due to its reversible jaws.”
Based on MTS proposal, Mr Cajic decided to invest in a few MAK-
RO-GRIP vices and test them to verify their effect in KOSS work
environment. In an industry where excess material can have a
dramatic impact on costs is what encouraged Cajic to exclusively
use the MAKRO-GRIP vises throughout the plant, regardless of the
application. For example, the MAKRO-GRIP system only requires
a very minimal amount of material to effectively grip the part,
SMTCL recognized there is a niche
to be filled in the vertical turning
area of the machining industry.
With that in mind, they recently
introduced two new vertical
lathes in their VTC line to North
America, one of which will be on
display at their booth no. 2526 at
CMTS 2011.
These machines are built using the
latest casting technology in an ISO
factory environment, and finite
element analysis is used in the
design process.
They are all equipped with name
brand components and accessories,
and sport the new modern ‘look and
feel’ first introduced in Chicago last
year, with new colours and laser-cut
and welded body components.
12 www.SMTCL.ca SEPTEMBER 2011
which alone save extra material costs over other work holding systems.
It has high repeatability by clamping work pieces in holding
teeth contour of jaw – no end stop is necessary. These vises have
a large clamping range due to their reversible jaws and they are
designed for easy and flexible handling due to their lightweight and
integrated zero-point clamping.
The benefits of the implementation of the MAKRO-GRIP in
KOSS work environment were excellent, as KOSS purchased
over 40 units from MTS. In particular, Cajic found that the
collective benefits of the MAKRO-GRIP system were ideal for
the new the Mazak Palletech System.
To become even more competitive worldwide and also to take
a closer step towards utilizing green methods in manufacturing,
Koss pursued lights-out manufacturing with the purchase
of a 5-axis manufacturing cell – the Mazak Palletech System.
“We are one of the first aerospace facilities in North America
to embrace this technology. Our first Mazak Palletech system
is equipped with 20 pallet capabilities and, we have another
Palletech system on order”.
“All these recent changes in project management, new technology
in machine tools, and intelligent workholding”, says Cajic,
“have contributed to not only increasing our competitiveness,
but also increased improving our quality and delivery timing to
a consistent 99.5%. The pride of accomplishing this status is
share throughout the organization.

The Turning of a New Page
by Kevin Hesch, In-House Solutions
It was commonplace
years ago to see standard
2-axis lathes in a
shop, or if you were lucky a
lathe with C-axis capabilities
so you could do some
basic milling applications on
your lathe, keeping your tool
on center.
In today’s quickly evolving
manufacturing environment
the trend is towards
a more capable/complex
multi-tasking machine to
help complete parts using
one machine and one fixture rather than having to tie up
multiple machines, operators,and fixtures. These multi-tasking
machines now come with a number of options that can
quickly add up in cost to the end user as well as increased
learning curve vs. older programming techniques. The bottom
line when deciding on what machine will best suit your
needs should be the parts you want to cut on it;does it fit,
can I machine all features or are secondary machine/operations
required, how difficult is it to program, how much training/implementation
comes with it? These are all commonly
asked questions, but what technology exists when referring
to CNC Turning Machines that may help address some of
these questions? Well here’s a short list of options commonly

Y-Axis- Coupled with a 2-axis lathe with C-axis capabilities, this
gives you a 3-axis mill setup on your lathe because it allows the
tool to travel off center for creating features such as keyways
with walls that are parallel to each other. Essentially it allows
you to program any 3- or 4-axis mill tool paths as well as any
2-axis lathe tool paths on your machine.
Sub Spindle- Gives you the ability to finish the front and back
of the part by transferring the stock once the first side is done
to the sub-spindle to finish the opposite side. With C-axis subspindle
options you can also maintain the orientation of the
part as it is passed back and forth between spindles to ensure
your part comes out correctly as features are cut in one spindle
and then the other (Phased Synching).
B-axis- this would take the Y-axis to the next level giving you
the ability to index a turret to a specified angle. This option
gives you the ability to do 5-axis milling on your turning center.
Usually a B-axis will come in two formats, one that can
simply index to an angle and cut locked in that position, then

index to the next angle, or one which can simultaneously index
the angle while in process, otherwise known as positional vs.
simultaneous 5-axis machining. Tilting of the B-axis also gives
more flexibility to existing tools by presenting the tool in a more
efficient manner to the part for some profiles.
Mini Turret- This type of turning tool takes a single tool holder
and turns it into multiple tools by having up to four tools at the
end of it. If the tool had 4 stations at the end of it you would
simply index to 0, 90, 180, and 270-degree increments to use
the individual tools without a tool change.
Lower Turret- This option coupled with an upper turret allows
you to synchronize your turrets to accomplish tasks such as
pinch turning (having both turrets cut a profile at the same
time), or machine two separate operations if you have a sub
spindle (one turret on main spindle and one on the sub-spindle)
This is just a short list of some more commonly available options
for turning centers. Other considerations that need to be
accounted for relate to peripherals to the machining center
itself such as utilizing the best tooling possible based on your
parts and the machine you chose, as well as ensuring any software
you use to program with can talk correctly to the machine
you purchase etc.
As machines get more and more complex the cost of the machine
you’re getting is rarely your bottom line. Ensure that
as you get into more complex equipment that you are getting
an implementation cost to get you running, not just to get a
machine on your floor. This will make sure that you’re new
investment isn’t an oversized paperweight for months before
you start producing parts.
