Procedure for centerless rounding by grinding of workpieces

摘要

Several surfaces of the workpiece (1) can be ground in one working cycle, and these may be the end faces (9,11,12) and grooves (13). The workpiece is machined by means of a profiling CBN grinding disc (3) which is set as near as possible at right angles to the rotational axis of the workpiece. A regulating disc (16-19) exerts on the workpiece a force component in the direction of its longitudinal axis, and pressure rollers (23,24) hold the workpiece against the regulating disc. Independent claims are also included for a device for carrying out the procedure.
