Paper Abstract

Along with modern science and technology development, Optical precise instrument, especially in space applied optical precise instrument, all set the very high request in the surface quality and the processing precision aspect, and have already achieved a nanometer precision to the surface roughness Ra request. Therefore this paper puts forward to use self-reacting machining method, process for floating polish, as well as measure and analyze the shape, appearance, roughness of work-piece surface. Through comparing proof with the work-piece surface condition that the grinding processing method of tradition gets: in from meet processing condition take off , the plasticity region processing that can be stabilized and realize brittleness optical material gets very good processing surface quality. Under the experiment condition of this paper, can get Ra 2-3nm processes mirror surface in shorter time.
