| Precise bearing steel-balls play a very important role in modern industry. The traditional lapping mode can not meet the requirement of processing accuracy and efficiency. A lot of scholars pay attention to the precise bearing steel-balls, and develop some new processing mode and processing technology. But they can hardly used in batch production for low lapping accuracy and efficiency, or complexity of the machine, or out of control.In this paper, a new processing program is found to improve processing efficiency and quality of the steel-ball, by the research of processing of steel-ball and principle of grinding.The main contents of this paper are:1. This paper analyses the homogeneity of ball billet grinding in different grinding way, to find out the pros and cons of all kinds of grinding way .A practicable and reasonable program is proposed in order to process high-quality bearing steel-ball efficiently.2. Precision grinding of steel-ball is free abrasive grit machining are ,and balling-up mechanism of ball lapping and principle of grinding is also studied.3. By the kinematics and dynamics analysis, and using MATLAB ,the new processing way that the grinding plate groove with a Bias processing and step grinding plate processing is put forward . When we apply this way , the quality of the ball and efficiency of processing .is improved.4. An automatic turning devices is designed , reducing installation error when the grinding plate is trued and dressed ,which improves the machining accuracy.
