High speed lapping hyperboloid by means of a lapping tool bending method

This paper discusses a new lapping hyperboloid method, which combines high-speed lapping technology with solid abrasives and lapping tool bending method. In this method a bending moment is acted as a lapping tool with solid abrasives, which makes it bend and form a shape on its working surface, which is similar as the generating line of workpiece surface. In lapping, the lapping tool is coaxial with the axis of hyperboloid surface of the workpiece and the lapping tool rotates around it to lap. This kind tool is used in forming lapping on a high speed lapping machine.
