Research on the Mechanism of Combined Raceway Superfinishing Technique of Precision Bearing

Abstract:

This paper analyzes the mechanism of combined raceway superfinishing technique of precision bearing, via the relationship between coarse and superfinishing oilstone and raceway geometric accuracy, probes forming mechanism of raceway geometric accuracy under double oilstone pressure as well as auto dynamic control functions. Additionally, this paper analyzes the feasibility of combined coarse and superfinishing technique, brings forward practice methods and steps of combined finishing technique; discusses how to realize smooth transition of technique parameters, so as to reduce surface texture changes of working pieces, achieve assistant grinding of superfinishing oilstone, improve surface quality of raceway and decrease reflection error of superfinishing. Meanwhile, this paper adopts embeded technology to realize auto dynamic control of oilstone pressure, so as to effectively eliminate surface error resulted from oilstone raising and furthermore enhance surface geometric accuracy of precision bearing.
