Processing of Lapping Track in Dual Rotated Plates Eccentric Lapping Mode

摘要

Dual Rotated Plates (DRP) eccentric lapping mode is developed on the base of traditional eccentric lapping mode for precise balls. Spin angle is an important target of expressing ball rotation in the lapping process. Whether lapping track can uniformly cover the ball surface or not is directly determined by the variation of the spin angle. Applying virtual prototype technology and ADAMS (Automatic Dynamic Analysis of Mechanical Systems) to simulate the ceramic ball lapping track in DRP eccentric lapping mode. And these results are compared to traditional one. At the same condition, the DRP eccentric lapping mode owns better lapping unifonnity than traditional one and it is easy to apply to science for the simplicity of structure and control. The result may offer theoretical basis for high-precision ceramic balls machining.
