A study of film polishing process for optical glass

With advances of technologies, the optical glass units are increasingly demanded together higher quality, due that the surface quality determines that of the entire optical instruments. The boron-silicon glass is studied in this paper using a self-made polishing machine as well as polishing film with various grain sizes. Through changing polishing speed and cooling method, the optimal polishing parameters of boron-silicon glass is speculated during the polishing process, which can simultaneously realize the high-efficient nano and green polishing. According to the results of experiment, a Web-based optimization database of polishing film parameters is established.
