减少分离型实体保持架垂直差的工艺改进

Technical improvement for reducing verticality of separation solid cage

保持架外圆或内圆对端面的垂直度(以下简称垂直差)直接影响着保持架兜孔的位置精度,很难满足产品的批量加工要求。为提高产品的合格率,从工艺流程和加工方法等方面做了很多改进和试验,收到显著的效果,使保持架的垂直差能够达到95%以上的合格率,同时大幅度提高了保持架的制造质量。

Verticality of inner circle and outer circle of cage to end surface （verticality） influences position accuracy of cage pocket directly, which result batch production is difficult. In order to improve passing rate of cage up to more than 95% and enhance cage production quality, processing and processing method have been tested and improved.
