The numerical control grinding and polishing technology is an optical part manufacturing technology in which the surface of the workpiece is processed into a desired surface shape by a numerically-precision machine tool, and then polished by a flexible polishing mold to make the workpiece meet the technical requirements.

Current status and development of optical parts processing, More and more precision instruments have been applied to the new technology combining opto-mechatronics, which has promoted the increasingly stringent requirements of multi-functional, high-performance and low-cost, and promoted the development of traditional optical parts production technology and the transformation of processing technology.
