ABSTRACT:
An apparatus for and method of grinding workpieces (e.g., universal joint crosses) in which the workpieces are automatically loaded, later indexed, and later unloaded from a rotary carrier (20) by an improved workpiece handling accessory (40). The workpiece handling accessory includes a rotating plate member (42) which has several spaced apertures (47, 48, 49) for receiving and retaining workpieces therein. A workpiece (33) is moved from a queue to a load station where the workpiece is transferred to the rotary carrier (20) for a grinding of the first two legs. A workpiece (22) on which the first two legs have been ground is removed from a pocket (22) of the carrier index (rotated) by 90.degree. by the plate member (20) and replaced in the same pocket (34) of the carrier (30) from which it had previously been removed so that the other two legs can be ground. A workpiece (35) on which all four legs have been ground is removed from the carrier and moved to a discharge chute (14) for completed parts.
