gantry clearance! - imes-icore GmbH

GPV / GPY
Capacity up to 5 axis with high
gantry clearance!
GPV/GPY - Now also as 5 axis system!
Many applications require a machine concept
which on one side is versatile in application
and on the other side offers large surfaces respectively
large travel strokes. Beyond that the
system should be economical and inexpensive.
Nothing easier than that: By the unique design
innumerable combination options of the machine
frame and the linear axis can be realised. Most
interesting in the CNC machine series GPV/GPY
is the both-sided driven Y- and Z-axis with very
high gantry clearance.
The application area and the materials which can
be machined are the same as our GPV/GPY series
and available with the same extension modules.
The high performance main spindle drive ES915
with 3,8 kW / 24.000 rpm or the new rotary /
swiveling (4th / 5th axis) can be used with the
highly solid x-traverse.

GPY 5-axis-simultaneous-milling
High-Tech-control and 7 drives provide
an excellent machine dynamic !
Especially in the field of model and mould making, everyone
is talking about 5-axis milling – production processes can be
optimized significantly
One can reach this advantages only provided the CNC-machine-system
has features like 5-axis transformation, jerk limitation
on track, online tool length compensation,
RTCP function (Rotation Tool Center Point), clamping position
correction and the perfect interaction of all those features
To be up to this, we together with technology partners further
developed our GPY machine series.
The control technology is PC based. Supporting dual core cycle
times less 1/1000 sec. are possible.
The CNC control works with G-code syntax according to
DIN 66025 plus machine related commands.
With the 4th and 5th axis, jerk free 5-axis simultaneously
machining is possible, in which the tool-tip cuts with constant
speed controlled by the function RTCP (Rotation Tool
Center Point).
To enable this feature the linear axis moving speed is tripled
compare to standard. Without angle gears the gantry construction
reaches much higher dynamic and quietness.
The complete machine geometry is spatially determined and
is known by the control. Therefore the compensation matrix
provide an accuracy of ± 0,03 mm.
The electronic hand wheel improves the operation friendliness,
spindle speed and feed rate can be adjusted infinitely.
Moreover this machine system is suitable for 3+2 machining
(milling with angled tool spindle).
Due to these features the GPY is an integrated machine
concept for many 5-axis milling applications:
FAST-PRECISE-EFFICIENT!

The PLC environment is fully integrated in the control system.
Hereby remote servicing for exact analyzing is ensured.
The complete data library is available to inform about the
system state.
Embedding of automated running works trough continuous
extension of the PLC programming according to IEC 61131-3,
CFC (Continuous Function Chart), FUP (Function Plan),
KOP (Kontakt Plan) and AWL (Anweisungs Liste).
The programming blocks of this PLC system are used by
designated manufacturers around the globe and guarantee
continuity and innovation force.
More information about it you may gather in a personal talk
with our technical sales team.
AC-servo motors with absolute encoders for rotating/swivel
axis are used.
This guarantees long term, reliable use of the CNC machine
system.
