一、概述 軸承环沟道的曲率和表面光洁度,对軸承的使用寿命有很大影响。在降低成本及提高劳动生产率的前提下,如何改善它的最終加工貭量,就成为目前軸承制造工业的主要課題之一。对于軸承环的沟道磨削,如果采用逐級細磨的加工方法,其生产效率是較低,要达到▽▽▽▽10級的光洁度是困难的。因此,圆柱及圓錐軸承一般系采用超精研法来加工;而对于向心球軸承,則采用抛光,卽用涂上磨剂(砂子)的砂布条和与 First, an overview of the bearing ring channel curvature and surface finish, the bearing life has a great impact. Under the premise of reducing costs and increasing labor productivity, how to improve its final processing quantity has become one of the major topics in bearing manufacturing industry at present. For the bearing ring trench grinding, if the gradual fine grinding processing method, its production efficiency is low, to achieve ▽ ▽ ▽ ▽ 10-level finish is difficult. Therefore, the cylindrical and tapered bearings are generally super-precision grinding method to the processing; and for radial ball bearings, the use of polishing, 卽 coated with abrasive (sand) emery cloth and
