我厂是生产气动、电动、流量仪表的工厂,产品零件的特点是品种多,零件小,精度高。因此金属切削机床(特别是车床)的工作台运动次数频繁,这样使机床的导轨磨损极其严重,在正常情况下,一台新机床或大修后的机床使用了三个月左右,导轨表面上的磨削花纹或铲削花纹基本全部磨平,(原花纹消失的磨损量约0.01～0.03mm)由于零件长度短,所以靠近车头处特别严
I plant is the production of pneumatic, electric, flow meters of the factory, product components are characterized by more varieties, small parts, high precision. Therefore, the metal cutting machine tools (especially lathe) table movement frequent, so that the machine’s rail wear is extremely serious, under normal circumstances, a new machine or overhaul machine used for about three months, the rail surface grinding Cut the pattern or shovel the basic pattern of all the smooth, (the original pattern disappears wear about 0.01 ~ 0.03mm) due to the short length of the parts, so close to the front of the Department of special strict
