一、机床导轨修理工艺的回顾 (一)以磨代刮的经历我系统所属工厂,共有金属切削设备几千台,每年在设备维修工作上耗费了大量的人力、物力和财力。特别是床身导轨及其配合面的修理,在采用人工刮研修理方式时,其刮研工时占总修理工时的60%还要多,采用床身导轨磨削、拖板配合面配刮的修理方式后,导轨面的修理工时,仍占总修理工时的30%左右。通过对磨削导轨面的使用,发现其耐磨性尚不理想,一般国产车床导轨磨修后,半 First, the machine tool rail repair process review (A) the experience of grinding scratch on behalf of my system factory, a total of several thousand metal cutting equipment, each year in the equipment maintenance work spent a lot of manpower, material and financial resources. In particular, the repair of bed rails and their mating surfaces requires more than 60% of the total repair work hours when using manual scraping and repairing methods. After the repair method, the repair time of the rail surface still accounts for about 30% of the total repair time. Through the use of grinding track surface, it is found that its wear resistance is still not ideal, after the general domestic lathe rail grinding, half
