Method of processing a workpiece |
摘要 |
A workpiece is processed to manufacture a poppet valve comprising a larger diameter head and a stem. First, the stem is ground to correct bending and warping and to remove black skin formed by a mold releasing agent, and, then the stem of the workpiece is cut, thereby preventing variation of the total length and wear of support rollers.
