我厂1970年从齐齐哈尔机床厂购买的C516A立车,自安装后,垂直刀架和侧刀架进给系统经常发生不稳现象,虽然进行过多次修理,但一直未得到解决。原几次修理总把它当作是因为电磁离合器的剩磁所引起的误动作,就将电磁离合器作退磁处理,过几天,又依然发生不稳现象。后来,我们从设计定量计算上来考虑,通过计算,电磁离合器摩擦片片数是足够的。以后,我们分析是不是片与片之间贴合得不好呢?我们就将电 Our factory purchased the C516A vertical lathe purchased from Qiqihar Machine Tool Plant in 1970. Since the installation, the vertical turret and the side turret feeding system often fluctuate. Although many repairs have been carried out, it has not been solved yet. The original several times to repair it as a whole because of electromagnetic clutch remanence caused by misoperation, the electromagnetic clutch for demagnetization, a few days, and still instability. Later, we consider from the design of quantitative calculation, through the calculation, the electromagnetic clutch friction plate number is sufficient. Later, we analyze whether the fit between the films is bad? We will call it electricity
