摘　　要：分析薄壁轴承的结构特点和加工难点,提出了一些改进措施,以某型薄壁深沟球轴承外圈磨削加工为例,针对出现的套圈端面平面度、外径圆形偏差超差问题,通过更换设备,采取各种加工调整方法等,解决了薄壁套圈的加工难题,满足了工艺精度要求。The structural characteristics and processing difficulties of thin - walled bearings are analyzed, and some im-provement measures are proposed. Taking grinding process for outer ring of a certain type of thin - walled deep groove ball bearing as an example, in view of oversized flatness of ring end face and outer diameter circular deviation, the e -quipment is replaced and various machining adjustment methods are taken. The machining difficulties are solved for thin - walled ring, and the accuracy requirements of process are met.
