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.
摘要翻译：发动机气门的阀杆和阀面分别由第一和第二磨轮磨削。用于驱动第二砂轮的电动机安装在第一板上，该第一板可沿着与轮的轴线垂直的方向由伺服电动机运动，并且在第一板的下方，第二板被设置成能够沿与轴平行的方向移动的轮子通过移动两个板，通过第二个砂轮将阀面倾斜地磨平。第一砂轮由可沿着与第一砂轮的轴线平行并垂直于其垂直的方向移动的第一修整器来修整。第二个砂轮由设置在支撑支柱末端的第二个修整器进行修整。
