M1080无心磨床砂轮主轴修复浅析

Repair of wheel spindle of M1080 centerless grinder

针对M1080无心磨床出现加工精度降低和抱轴现象,采用定心工艺套修配主轴、轴瓦的方法,严格控制主轴与轴瓦的同轴度,使动压轴承楔形间隙大小合适,建立起良好的动压工作过程,很好地解决了以上问题。

Aiming at M1080 centerless grinder processing precision low and appearing clamping shaft phenomenon,centering sleeve was adopted to engage spindle and bush,and strictly controlling the coaxial tolerance of spindle and bush,appropriate to the wedge gap size of dynamic pressure bearing,to establish good dynamic pressure working process,so the above problems was solved well.
