在党的提高劳动生产率、向自动化进军的正确号召下,我厂领导、工人和技术人员紧密地结合在一起,发挥集体力量,改装普通车床成为加工锻件的全自动液压仿形车床,向五一国际劳动节献礼。我厂生产内燃机中的进、排汽门(工作物见图1),批量很大。过去车削加工是采用逐道工序流水加工的方法。由于工序较多,所以尽管在车速、走刀量、切削深度和夹具方面作了不少改进,但是占据整个加工工时很大比重的辅助工时,却很少有显著的改善。因此,为了进一步压缩工时,提高
Under the correct call of the Party to improve labor productivity and march toward automation, the leaders, workers and technicians in our factory are closely combined to exert collective power to transform ordinary lathe into an automatic hydraulic copying lathe for forging. International Labor Day gift. I plant the import and export of internal combustion engine exhaust valve (work shown in Figure 1), a large volume. In the past, turning machining was a process that was run on a sequential basis. Due to the large number of work steps, although there have been many improvements in vehicle speed, cutting depth, depth of cut and fixturing, there has been very little significant improvement in the number of auxiliary workhorses that take up a significant portion of the total processing time. Therefore, in order to further reduce working hours, improve
