一、传统配磨工艺目前,车床大修普遍采用配磨方法。配磨后床身山形导轨山尖位置在垂直面内下降 h 值;在水平面内位移 L 值;平面导轨在垂直面内下降 h′(如图1所示)。大溜扳导轨面在配磨中尺寸发生了变动,而三杠(丝杠、光杠、开关杠)两端(后支 First, the traditional grinding process At present, overhaul lathe method commonly used with grinding. After grinding, the position of the mountain tip of the mountain-shaped guide rail is decreased by h in the vertical plane; the L value is displaced in the horizontal plane; and the plane guide rail is lowered by h in the vertical plane (as shown in FIG. 1). Large slide rail surface in the wear with the size of the mill has changed, and three bars (screw, light bar, switch bar) both ends (back
