The NVD4000 DCG VMC lets
shops meet demanding surface
finish requirements. With
Mori Seiki's Driven at the Center
of Gravity (DCG) technology, the
machine's net driving force acts
through the center of each axis,
a design that reduces vibration
without sacrificing speed for accuracy.
There are five ballscrews on
the NVD4000 DCG - two on
the Y, two on Z, and one on X.
Mori Seiki only incorporates
twin ball-screws where they provide
benefit, whereas placing
dual ballscrews in all three axes
can reduce a machine's overall
dynamic response.
With input increments of 0.1
microns, all three axes have direct
scale feedback, and the spindle
has dynamic thermal-displacement
control. The machine's
DataServer stores large
part programs and quickly
transfers them to the
control during cutting.
A 2.8-sec chip-to-chip
toolchange time quickly
serves the machine's
27.6 x17.7-in. work table.
And its 40-taper spindle turns at
12,000 rpm (20,000 rpm optional) and
delivers 25 hp.
