摘要

A method for forming a precision ball track in a part, especially an outer or inner race member of a constant velocity ratio universal joint, wherein the part is initially formed with a relief groove 32 in the base of the ball track so that when the ball is subsequently ground to a predetermined precision shape, the relief groove reduces the wear on the grinding wheel used during the grinding operation.
