摘要:
A method of reducing hard machining time, and correspondingly increasing hard machining tooling life, of a non plunging type constant velocity joint for use in reduced angle applications. The method comprises forming a recess having a larger formed radius in a portion of the ball track and cage track areas that is non-functional in low angle operations prior to heat treat hardening. The new process results in a significant reduction of approximately forty-five percent in the hard machining of the ball and cage track surfaces.
