Paper Abstract

Lapping is an important method in optical element machining. In lapping a workpiece is pressed on the lapping to by a press head through a press disc, which produces a friction force between the lapping tool and the workpiece and forms lapping. The friction moment between the press head and press disc resists workpiece rotating and affects machining accuracy. This paper in theory discusses this moment in detail. According to the press head and press disc elastic deformation produced under action of pressure, the contact stress distribution between them can be got. By means of this stress distribution function, the infinitesimal moment can be got. Through integrating an analytic result of resultant moment can be got too. From this result we can easily find that the factors affecting the moment and affecting role, which provides a theoretical base for increasing lapping accuracy, reducing the moment and a base for researching relative motion in floating lapping deeply.
