Three quenched bushes are pressed on the hollow spindle (sleeve) with a big interference fit, thus the spindle can move forward and backward precisely within the bush.
三个大干涉配合的淬火衬套压装在空心轴（镗套）上，因此，主轴能在衬套内前后精确移动；

A measure is taken to use bearing instead of spindlebush as a result efficiency is raised, on the basis of saving cost, production period is also shortened.
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。
