Abstract

The invention is concerned with the machining of lon­ gitudinal ball tracks into the inner joint members of uni­ versal joints. A workpiece for the joint member is clamped in position by clamping mechanism of a spindle mecha­ nism (22), by which a split collet (38) is opened into inte­ rior engagement with the workpiece, pulling the workpiece onto an annular base surface (32) and into engagement with internally curved surface portions (35) provided by resilient fingers, which engage with the exterior surface (82) of the workpiece. In this position, the longitudinal axis (LA2) of the joint member coincides with the longitudinal axis (LA1) of the spindle mechanism. The spindle mecha­ nism (22) is then moved arcuately about a further axis (LA3) relative to a rotating grinding wheel (14) so that the grinding wheel effects machining of one of the ball tracks of the member. Subsequent to retraction of the grinding wheel, the spindle mechanism (22) is rotated about its lon­ gitudinal axis (LA1) to present to the grinding wheel (14) another surface portion of the joint member, and another ball track is machined into the workpiece.
