This paper discusses a new lapping ellipsoid method, which combines high-speedlapping technology with solid abrasives and lapping tool bending method. In this method, a bendingmoment is acted on lapping tool with solid abrasives, which makes it bend to form a shape on itsworking surface, which is the same as generant of workpiece shape. This kind tool is used informing lapping on a high speed lapping machine.With the development of science and technology, the requirements for optics systems becomehigher and higher, e.g. good quality of imaging, little loss light energy, small size and light weightetc. It is difficult to reach above requirements by using traditional sphere lens/mirrors in opticssystems. Aspheric optics elements can be used to solve these problems. In optics systems, by usingaspheric optics elements, the number of optics elements can be reduced, the system structure can besimplified, the weight and size of the system can be reduced, light energy loss can be reduced too,imaging errors can be avoided and imaging quality can be improved. Ellipsoid is a kind of surfacebeing used widely within all kinds of aspheric surfaces. The main purpose of this paper is tointroduce a method of lapping this kind of surface at high speed
