Abstract
A fine grinding machine for crankshafts, camshafts and the like, has a fixed headstock housing in which the spindle carrying the workpiece chuck is rotatable and axially reciprocatable. The chucking action is effected by an axial displacement of the spindle by a setting mechanism which acts upon the spindle via the same member as that which transmits the axial reciprocation thereto for the oscillating drive. A flexible connection in the rotating drive permits the axial movement.
