    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.

    摘要: A stem and a valve face of an engine valve are ground by first and second grinding wheels respectively. A motor for driving the second grinding wheel is mounted on a first plate movable by a servomotor in a direction perpendicular to the axis of the wheel, and under the first plate, a second plate is disposed to be movable in a direction parallel with the axis of the wheel. The valve face is ground obliquely by the second grinding wheel by moving the two plates. The first grinding wheel is trued by a first dresser movable in directions parallel with and perpendicular to the axis of the first grinding wheel. The second grinding wheel is trued by a second dresser provided at the end of a support strut.
