Large aperture lenses which are used for single-lens reflex cameras and television cameras are manufactured by polishing requiring sufficient removal amount with a few micrometer depth to rid micro clacks completely after ultra-precision grinding. However, a prolonged polishing deteriorates the shape of the lens, which is accurately produced by the grinding process. In order to reduce the amount of polishing, ductile-mode ultra-precision grinding is demanded. In this study, The rubber-bonded wheel were employed to enhance the grinding performance. Natural rubber and chloroprene rubber bonded wheels, which have different hardness, were chosen, and the influence of the hardness of rubber-bonded wheel on the ground surface was investigated. By using chloroprene rubber-bonded wheel, the better surface quality was achieved. Softer rubber is assumed to enhance the surface quality and suppress the brittle fracture generation.
