Research of Grinding Methods for Large Lead Ball Nut

Abstract

To solve the interference problem during the grinding process of large lead ball nut, a new forming grinding system based on flexible shaft has been designed in this paper. The paper analyzed and compared with three grinding methods including reducing setting angle, deflecting setting angle and adopting flexible shaft grinding system to figure out their influence on possibility, precision and efficiency of grinding. The result shows that the flexible shaft grinding system designed can avoid interference effectively. Additionally, it can also meet the requirement of efficiency and precision when grinding the large lead ball nut.
