Precision machined parts are a kind of mechanical manufacturing with precise and fine features, and their creation and application fields are extremely wide. In the manufacture of high-precision optoelectronic systems, laser devices, large-scale integrated circuits and other fields play an important role. For example, precision machined parts are widely used in micromechanical technology, precision grinding technology and cutting technology.

The manufacturing process of precision machined parts usually includes roughing, semi-finishing, finishing, optical finishing and ultra-precision machining stages. Among them, precision cutting, fine mirror grinding, precision grinding and polishing are the main processing methods.

The application areas of precision machined parts include aerospace, automotive manufacturing, medical devices, electronic equipment, and so on. For example, in the aerospace field, precision machined parts are used to manufacture key components of aircraft engines, satellites, rockets and other equipment. In the field of automobile manufacturing, the precision machined parts are used to manufacture key components of automobile engines, transmissions, brakes, and the like. In the field of medical equipment, precision machined parts are used to manufacture scalpels, endoscopes, heart stents and other key components of the equipment. In the field of electronic equipment, precision machined parts are used to manufacture key components for mobile phones, computers, TVs and other equipment.
