- Vertical movement of the grinding wheel headstock

The vertical movement is performed on SCHNEEBERGER linear needle slides and is controlled by a precision ball screw and a stepper motor.
Vertical axis resolution: 0.001 mm.
Dimension read on the display. Display resolution = 0.001 mm.
Electronic handwheel for manual movement.

- Transverse movement

The sub-table carriage slides on SCHNEEBERGER linear needle slides.
The transverse movement is controlled by a precision ball screw and a stepper motor.
