在卧式镗床的维修中,其主轴副(镗轴、镗套、花盘主轴)是镗床的关键部件之一(见图1),直接影响着工件的加工精度。在过去的修理中,往往由于修理难度较大就整套更换,造成了浪费,影响了产品质量。 近年来,我厂广大机修工人和技术人员本着自力更生、以修为主的原则,对数台镗床的主轴 In the maintenance of horizontal boring machine, the spindle (boring shaft, boring sleeve, spindle spindle) is one of the key components of the boring machine (see Figure 1), directly affect the machining accuracy of the workpiece. In the past repairs, often due to repair more difficult to replace the entire package, resulting in a waste, affecting product quality. In recent years, our factory majority of mechanic and technical staff in self-reliance, the principle of repair-based, logarithmic boring machine spindle
