我厂M1432外圆磨床使用七年以后,发现砂轮主轴油封处严重磨损,产生漏油,若采用常规的修复方法(镀铬、堆焊、镀套环等)修复,均需将主轴拆下,修复后重新装配调试,比较复杂。为此,我们进行了改进(附图),效果很好。 After seven years of using the M1432 cylindrical grinding machine, it was found that the main shaft oil seal of the grinding wheel was severely worn and oil leakage occurred. If the conventional repair method (chrome plating, surfacing, plating loop, etc.) is used, the spindle should be removed and repaired After reassembly debugging, more complicated. To this end, we made improvements (with photos), works well.
