Because of the high hardness and brittleness of optical glass, it is easy to produce surface defects and sub surface damage in the process of processing, which is a typical difficult to process material. Its ultra smooth surface forming technology and high efficiency and low cost processing technology have become an important research topic in the fields of national defense technology, aerospace, electronic information and so on. For optical glass and other hard and brittle materials, ultra precision grinding technology is the best way to achieve ultra smooth surface. Therefore, the United States, Germany, Japan, the United Kingdom and other industrial developed countries are very active in the research of ultra precision grinding technology of optical glass and other hard and brittle materials. They have developed advanced high-precision and high rigidity grinding machines for the research of ultra precision processing technology of hard and brittle materials, and relevant research results have been applied to the field of national defense and civil industry. In recent years, the research on ultra precision grinding equipment and technology of hard and brittle materials such as optical glass has been listed as the key research content.
