Fine finished steel ball set into a bearing have been needed in precision machinery field. Spin angle controlled ball lapping method developed recently, is to have an excellent performance to lap the ball, in which V-groove lapping plates are separated into two parts and three plates are able to rotate independently. Present paper focuses on an effect of lapping plate geometry on finishing characteristics of the steel ball. It is round that R-curved lapping plates constituting of V-groove have yielded greater stock removal than flat ones. Experiments show that the stock removal is dependent upon spin angle θ which is closely related to slipping distance of ball. Measurements of a sphericity of lapped ball indicate that the geometry of lapping plate has small effect with respect to improvement of it, but causes larger stock removal rate and very smooth surface.
