Abstract . The sliding states of precision ball is an important factor in lapping uniform. To study the sliding state of ball in Rotated Dual-Plates(RDP) Lapping Mode, this paper analyses several kinds of sliding states from theory to the simulation based on the kinematics and dynamic.It is assumed that the slide could occure between the ball and inner lower plate or between the ball and outer lower plate. The simulation results show that there are several numerical combination among the spin angle θ, the coefficient ratio of sliding friction and the rotating speed ratio of the outer lower plate and inner plate,which is beneficial or adverse to improve the lapping uniformity.The results also show Machining load and the friction coefficient is increased, the critical speed of lapping plate also is higher, the ball is more not easy slide,and the critical speed of slide could be obtained to direct processing.
