Since full complement needle bearing outer ring flanges and raceway were processed by two turning tools, middle lap would occur and the left amount of grinding will increase. Aimed at these problems above, using one turning tool to process left and right flanges and raceway at the same time would be a good solution. At the same time, after quenching bearing outer ring, turning tool was used to hard turn left and ring flanges to prevent flange grinding burn.
