Product Guide CNC Vertical Grinding Machine  

This machine enables high-precision multi-process grinding of I.D., O.D., end face, and coupling tooth surface in one chucking, offering process innovation.
*TC type uses a DDM (Direct Drive Motor) for its spindle, offering indexing increment of 0.0001°. (22TC offers indexing increment of 0.00001°.)

1. The machine is equipped with a high-rigidity, high-power grinding spindle.
2. High-precision full indexing is available for a turret-type wheel head.
(CT table is equipped as standard.)
3. High-speed feedrate
4. DDM (Direct Drive Motor) is used for the spindle C-axis control. (*TC type)
5. Hard turning is available (*option)
