Continuous indexing function on wheelhead

High-accuracy indexing turret is equipped as standard on wheelhead, which enables crowning process on taper. Even with difficult workpieces, we still achieve process innovation by grinding ID, OD and face in one-time chucking.

Profile grinding with work spindle DD motor TC-type

DD (Direct Drive) motor is available as a work spindle option. It enables high-speed and high-accuracy indexing of work table to perform profile grinding such as cam, curvic coupling, etc. DD motor is maintenance-free by having no wearing parts in the driving part which is another big advantage.

Significant reduction of cycle time with hard turning function Option

NVGH series has the highest rigidity in our lineup. With hard turning function, you can remove most of the grinding stock in advance which significantly reduces cycle time.
