The Cost-Effective Sharpening Machine

GX7 : a cost effective CNC tool sharpening grinder w
A perfect sharpening package
ANCA’s GX7 CNC tool and cutter grinder is an
entry-level sharpening machine. It offers both
flexibility and speed to tackle a wide range of
different high precision cutting and drilling tools in
one set-up. It is equally productive on single tool
jobs as well as on a batch of tools of different types
and geometry.
The GX7 is purposely designed and developed to
meet the needs of the tool sharpening industry,
providing:
• Quick setup and job change over
• Fast cycle times
• Very high tool accuracy
• Superior surface finish
• Versatility to handle a wide variety of
sharpening applications
• High reliability.
The ANCA ToolRoom ® software suite enables quick
and easy set-up for tools such as drills, end mills,
burrs, profile tools and other special tools.
The standard probing system allows the machine
to accurately locate the features of the tool to be
sharpened. The integration between the probe
and software makes accurate and precise tool
sharpening possible.
Flexibility and speed
The GX7 is small and compact yet has a large
working envelope making it suitable for a vast
array of tool types, geometries and shapes.
The machine has been designed with the operator
in mind offering high level ergonomics for optimal
operator access and comfort.
The single direct drive bi-directional spindle - with
dual wheel packs at either end of the spindle -
enables the possibility of using up to eight wheels
in one set-up. The design of the spindle gives
complete unrestricted access to the work piece.

GX7 : a dedicated sharpening machine
Meeting the demand
The industry has high demands with regard
to accuracy, machine reliability and efficiency.
ANCA GX7 meets these expectations and
sets new standards for a CNC tool sharpening
machine.
The GX7 has been designed using the latest
Unigraphics NX solid modelling software. The
mechanical design was optimized using the
latest FEA software tools which means the
machine is extremely rigid and strong.
Designed for the operator
The GX7 has been designed with the operator
in mind. Access to wheels, coolant pipes and
headstock work holding is an effortless reach
from the machine operator access door.
With the addition of easy to change coolant
manifolds which can be set up to suit each
wheel package outside the machine, the work
preparation is reduced to a minimum.

Polymer concrete base
To fully utilize the rigid design of the machine,
it is important to start with a strong foundation.
The GX7 is built on a polymer concrete base,
which provides better vibrations dampening
and significantly contributes to the machine’s
robustness and strength.
Direct-drive multi
directional spindle
The wheel spindle is based on a direct-drive
motor design capable of 9000 rpm. With a
constant power of 4.2 kW (5.6 hp) and peak
power of 9.5 kW (12.7 hp), it offers more
than enough power for any sharpening task.
There are no belts, pulleys or gears, thereby
eliminating the key source of vibration usually
attributed to belt driven spindles. Direct-drive
significantly contributes to the superior surface
finish on the ground tool and guarantees higher
machine reliability.
All linear and rotary machine axes on the GX7
also use direct-drive technology giving greater
positional accuracy.

Options
Machine-enhancing options
A variety of options can further enhance the machine’s
flexibility. These include a range of pneumatic or
hydraulic work piece clamping systems, popup steady,
iView tool measuring system and automatic tool loader
options.
iView is a precise tool measurement system developed
by ANCA. It can be quickly set up inside the machine to
provide measurement data, without the need to remove
the tool from the work piece clamping. This data can
be fed into the grinding program for automatic exact
compensation resulting in a precisely ground tool.
A wide range of applications based on the renowned
ANCA iGrind platform is available within ANCA
ToolRoom ® software suite. The iGrind interface is
user friendly, offering a high degree of flexibility and
operational efficiency. The ToolRoom ® suite of software
supports the grinding of drills, end mills, profile tools,
burrs, routers and many other special applications.
‘ANCA investigated
what the industry
demanded in a tool
sharpening machine
… and the GX7 is
the result.’

Loader options
To enhance the GX7’s capabilities, it can be equipped
with several loader options.
CLX - Compact Loader
Designed to meet strict space and budget
specifications the economy and efficiency of the
CLX means that automatic loading is now viable for
companies who do low-volume production runs and
cannot justify more complex systems. The loader arm
is fully contained within the canopy so the machine
footprint is not increased and the loader utilises the
existing machine axes, which saves cost and space.
DLX - Drum Loader
Suitable for loading straight-shank tools directly from
the loader pockets or tools held in Nikken KM16, 20 or
32 collets. The DLX provides the flexibility to be set up
with a variety of tool types and sizes.
