摘　　要：轴瓦与主轴配合精度要求高,更换调整非常困难,一旦出现问题,解决难度大。通过用轴承代替轴瓦,不仅效率高,同时节约了成本,缩短了周期,使用效果良好。Because high fit accuracy is demanded between spindle bush and spindle, it's difficult to replace or adjust it once the bearing shell breaks down. A measure is taken to use bearing instead of spindle bush as a result efficiency is raised, on the basis of saving cost, production period is also shortened.
