High Quality Centreless Grinders

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

The grinding wheel and regulating wheel are bearing type spindles for higher rigidity. During the 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 Work rest stopper control, to satisfy requests for the customized specification.
