ABSTRACT:
The grinding machine is of the type adapted for grinding a workpiece having a surface of revolution such as a taper or barrel roller of a rolling element bearing. The two end faces of the workpiece are clamped between adjacent ends of two mandrels which are rotatable about a common axis. The adjacent ends of the two mandrels are formed with respective noses for effecting the clamping of the workpiece. One nose is formed with a seating in the form of a flat face or a concave surface of revolution the axis of which is coincident with the common axis of rotation of the two mandrels. The other nose is provided with a cavity having a tapered opening through which a spring loaded ball partially protrudes. A backup surface of the ball is provided within the cavity perpendicular to the common axis of rotation of the two mandrels over which the ball can roll within the limits imposed by the cavity to facilitate mating of a preliminarily shaped end face of a workpiece with the complementary seating on said one nose in order to accurately locate the workpiece for grinding.
