我厂KNA-110立车是1958年进口的一台关键设备。十几年来存在严重的掉刀问题,始终没有得到很好的解决。直到今年大修中,经过对立刀架部分的改革,使零件在转动中由滑动摩擦改成滚动摩擦,即减少了零件在转动时的摩擦阻力,提高了零件在转动时和平衡锤平衡刀架时的灵敏度,才从根本上 Our factory KNA-110 vertical lathe is a key equipment imported in 1958. Ten years there is a serious problem of dropping the knife, has not been well resolved. Until this year overhaul, after the opposite part of the turret reform, so that parts in the rotation by the sliding friction into rolling friction, that is, to reduce the friction friction parts rotation, increased rotation of the parts and the balance when the balance turret The sensitivity is only fundamentally
