Features

Plunge grinding applications
Angular approach centerless machines are used in some multiform plunge grinding applications which require to achieve tight tolerance accuracies.
Hybrid approach
This hybrid approach also allows us to grind faces or shoulders where straight-head type centerless grinder do not.
Bearing type spindles
Grinding wheel and regulating wheel are bearing type spindles for higher rigidity. During grinding process, the stress is even on two ends to avoid taper shaped workpieces.
CNC controller
The 4 axes CNC control of Grinding wheel auto. Infeed, Regulating wheel auto. Infeed, Grinding wheel auto. dressing (vertical) and Workrest stopper control, to satisfy requests for customized specification.
