Study on Hard Turning Process of Large Cylindrical Roller Bearing Flanges

At present, grinding mode is used for the finishing process of large cylindrical roller bearing flanges. However, because of low efficiency, large consumption of grinding wheel and grinding fluid, high costs, serious pollution of cutting waste fluid, and more importantly, easy to generate grinding burns and cracks defects, grinding machining has become a technical problem that troubles the economic and effective processing of large bearing ring flanges in the bearing industry. Therefore, the research on the hard turning technology for the finishing process of large cylindrical roller bearing flanges is carried out in the paper. The experiment investigations have shown that the finishing quality of large cylindrical roller bearing ring flanges can be better and more economically guaranteed by hard turning process.
