Different spherical shape models of precision ball-lapping are presented and discussed in this paper. A selective analysis of spherical surface morphology model of rotated dual-plates (RDP) ball-lapping is presented. With combined shape errors of three contact points, the spherical surface morphology is more close to the real surface of precision ball. Simulations show that the spherical surface morphology model of RDP method can well express the shape errors of precision balls. The wear rate is easily obtainable as an empirical function of the contact forces, velocities and material properties of the surfaces in contact. The expansion of the net material removal rate gives the rate of the spherical harmonics. The modeling method can capture the change of single point in the process of lapping. Then the parameters, such as lapping speed, preload, and entry point orientation can be studied using this model in the subsequent research.
