Process innovation by multi-process grinding

CVG series is equipped with internal and external grinding spindle on 3-position turret as standard to stably provide high grinding performance for various workpieces. Grinding multiple processes in one-time chucking enables reduction of setup change time and cycle time. It also leads to cost cutting by reducing production cost of the fixtures and contribute to productivity improvement.

Significant improvement of productivity with APC system Option

APC (Auto Pallet Change) system allows workpiece change and setup during grinding operation, and enables significant improvement of productivity. By placing APC on the side of the machine, operating area is secured on the front which realizes outstanding space saving and operability equivalent to a stand-alone machine.

Profile grinding with work spindle DD motor Option

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.
