The aspherical lenses are used for various optical instruments. It is thought that the ultra precision grinding is suitable for manufacturing these lenses and the molds because of the viewpoint on the material and accuracy. But it is necessary to form the grinding wheel in the arc section shape in high accuracy to grind the curved surface in high accuracy. We examined the forming superabrasive wheel in high accuracy on grinding machine in three methods. After that, cemented carbide often used for the mold are ground in best method of them. As a result, the processing accuracy of profile accuracy 0.2μm and surface roughness 10nm were obtained.
