ABSTRACT:
A centerless grinder for shaping bars during a through-feed grinding operation. A special centerless grinder is adapted to receive a workpiece at an inlet end between the regulating and grinding wheels and to discharge the workpiece at an exit end between the wheels while a special pivoting mechanism is provided to relatively pivot the wheels with respect to one another about a pivot point proximate the wheel inlet end. The relative pivoting movement of the wheels is performed in timed relationship to the through-feed movement of the workpiece, so that the exit spacing of the wheels determines the final, exiting, diameter of the workpiece at a given time. Therefore, varying cross-sectional diameters of a workpiece may be achieved along a work axis by appropriate timed movement of the wheels.
