普通车床因主轴轴承孔松动,往往使被加工零件出现椭园、波纹等情况。采用的修理办法有粘结、喷镀、镗孔镶套、改静压轴承等工艺。其中有些工艺涉及到工厂、设备条件、经济价值等原因而受到限捌。相比而言,镗孔镶套工艺维修方便、价值经济,使用效果较好。床头箱镗孔镶套,一般都在镗床上进 Ordinary lathe bearing holes due to loose, often to be processed parts appear oval, ripples and so on. The repair methods used are bonding, spray plating, boring set, change hydrostatic bearings and other processes. Some of these processes are limited to factories, equipment conditions, economic value and other reasons. In contrast, boring set process easy maintenance, economic value, the use of better. Bedside box boring set, usually in the boring machine into
