" ORIGINAL POINT MACHINE TOOLS WAS ASKED BY
GUANGDONG UNIVERSITY TO DEVELOP A MACHINING
CENTRE THAT COMBINED HIGH SPEED LASER CUTTING " AND
of material, and its very short 1030
nm wavelength means that it is
suitable for micro/nano processing
applications.
Entirely controlled by NUM’s
latest-generation Flexium+ 68 CNC
platform, the ML125 machining
centre has eight servo axes, two
independent NC channels and fast
application-specific I/Os embedded
in the NCK hardware. Movement
of the fully articulated laser head is
controlled by five NUMDrive X servo
MILLING CAPABILTIES.
drives, with high speed interpolation
between all five axes – and the
CNC system provides a full RTCP
function.
By employing a special hollow
shaft torque motor and a linear
motor drive, the dual laser head
has an exceptionally high positional
accuracy of 8 micrometres (0.008
mm), with a repeatability of just
5 micrometres. The associated
A/C axis rotation platform has a
precision rotary feed function with a
positional accuracy of 5 arc minutes.
The milling head uses a 40,000 rpm
spindle motor, and laser cutting
and milling can be performed with
just one clamping operation, which
further improves process accuracy.
According to Bruce Zheng, ceo of
OPMT, “The requirements of the
industrial processing market keep
changing, which means that our
machines need to be extremely
flexible so that they always offer
customers what they need.
Partnering with NUM helps us to
achieve this; its open architecture
CNC systems are easy to integrate
with third-party products such
as motors, and the company is
prepared to offer the long term
commitment and technical support
that is necessary for successful
completion of complex machine
projects.”
The ML125 machining centre is now
installed in a research laboratory at
Guangdong University of Technology.
The ML125 machining centre has a dual laser head
capable of both high speed and high quality cutting.
The HMI of the ML125 machining centre is based on
NUM’s Flexium touch screen technology.
