M7130平磨是磨削加工中常见的设备,主轴采用滚滑混结构。由于结构上的原因,加工工件常出现波纹,光洁度不好,发热甚至造成抱轴等问题。我们对这种机床主轴部件采用了只在原瓦上作简易补充加工,把原来的单油楔滑动轴承改为多油楔动压轴承,同时提高主轴的组装精度,使这种结构陈旧的设备焕发了青春,达到了精磨无波纹、光洁度好,粗磨效率高,温升低,不抱轴的要求。
M7130 flat grinding is a common grinding equipment, the spindle using slippery mix structure. Due to structural reasons, the processing of the workpiece often appear ripples, poor finish, fever and even caused the shaft and other issues. We use the spindle components of this machine only for simple supplementary processing on the original tile, the original single wedge sliding bearings to multi-wedge hydrodynamic bearings, while improving the assembly accuracy of the spindle, the aging structure of this equipment glow A youth, reached a fine grinding no ripple, good finish, rough grinding efficiency, low temperature rise, do not hold the shaft requirements.
