Ball screw nut coolingFeed axis thermal displacement largely reduced Feed drive strength maintained in stable condition

Rigid coupling

Center weightBy minimizing the distancebetween weight center and thefeed drive center, the inert iamovement is reduced allowing forfaster feed rates and a moreprecise part.

High output / High inertia motorThrough overall axial load / motor inertia ratio of less than 50%, we haveimproved the responsiveness of feed drive.

Machining condition selection function

with DSQ without DSQ

It is possible to change machining condition in 10 steps by using R code at the program. - Improving productivity (high speed at rough machining, high precision at precision machining)

NC parameter such as maximum feed and accelation time constant can be set automatically

It enables to calibrate the change in position of tool through the expansion ofspindle shaft at high-speed rotation.
