套圈无越程槽的圆柱滚子轴承 ,其套圈档边和滚道不能用常规的分步法磨削 ;采用初磨两端面→初磨外径→初磨档边→初磨滚道→附加回火→细磨两端面→细磨外径→细磨滚道→附加回火→终磨两端面→终磨外径→复合磨削滚道→挡边→超精滚道的工艺达到小批量生产合格产品的目的。 Rings without groove more cylindrical roller bearings, the ring and raceway ring can not be used conventional step grinding; the initial grinding of both end surfaces → initial grinding outside diameter → initial grinding arch edge → initial grinding raceway → additional tempering → fine grinding both end surfaces → fine grinding outer diameter → fine grinding raceway → additional tempering → final grinding of both end surfaces → final grinding outer diameter → composite grinding raceway → ribs → super-precision raceway technology to achieve Small batch production of qualified products.
