摘　　要：3MZ3210超精研机是用来精研深沟球轴承外沟道的专用设备。通过对超精研设备夹紧机构和工件轴的改进,以多磁极式电磁无心夹具及长通轴取代了压辊式夹紧机构和悬臂式工件轴,收到了满意的效果。The 3MZ3210 super lapping machine is the specialized equipment used for lapping the outer groove of deep groove ball bearings. The improvement in the chucking mechanism and the part axle of super lapping equipment has achieved satisfactory effect by adopting multi-pole electromagnetic centreless fixture and long hollow axle to replace roller-compression chucking mechanism and cantilever part axle.
