针对微型高精度无磁轴连轴承细长轴台阶内孔在精密磨削时无法装夹定位的问题，设计了一种二级夹具，解决了无磁材料在电磁无心夹具上加工定位以及细长轴刚度低造成台阶内孔锥度差的问题。
針對微型高精度無磁軸連軸承細長軸檯階內孔在精密磨削時無法裝夾定位的問題，設計瞭一種二級夾具，解決瞭無磁材料在電磁無心夾具上加工定位以及細長軸剛度低造成檯階內孔錐度差的問題。

There is an inner step hole in slender shaft of high precision miniature non-magnetic bearing with shaft,and it is difficulty to clamp and locate the shaft on the electromagnetic centerless fixtureduring precisely grinding the bore. A secondary fixture is designed to solve the problem and the taper difference of the bore caused by low stiffness of slen-der shaft is reduced.
