M7475B立柱圆台平面磨床是我厂磨削轴承套圈端面的专用设备,工作台滑鞍导轨与床身导轨间原采用油线润滑(图1),在滑鞍导轨油池里装有管接头和油线,利用油线的毛细管及虹吸管作用向摩擦副供油,由于上导轨很重,承压后供油效果很差。78年我们对该磨床导轨润滑方式进行了改进(图2),采用手动油泵强制送油的方法润滑导轨,效果很好。 M7475B column circular table surface grinding machine is my factory grinding bearing ring end surface of the special equipment, table rail saddle rails and bed rail original oil lubrication line (Figure 1), in the saddle rail fuel tank is equipped with fittings and Oil line, the use of oil capillary and siphon effect to the friction pair for oil, due to the heavy rail, bearing pressure after the poor results. 78 years we have improved the way of grinding the guide rail (Figure 2), using a manual pump to force oil lubrication guide rail, the effect is very good.
