The design of this CNC Angular Approach type Centerless grinder provides high precision, flexibility and compactness. Each machine from PALMARY presents the outstanding accuracy as you have come to expect. That is why PALMARY's centerless grinders are fully recognized by worldwide customers.
Plunge grinding applicationsAngular approach centerless machines are used in some multiform plunge grinding applications which require to achieve tight tolerance accuracies.
Hybrid approachThis hybrid approach also allows us to grind faces or shoulders where straight-head type centerless grinder do not.
Bearing type spindlesGrinding 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.
