High precision machining has high precision and high processing costs, mainly used in civil military fields such as national defense, medical equipment, aerospace, and electronic production. With the continuous optimization and upgrading of China's industrial structure, the demand for mechanical parts processing is also increasing. Therefore, it has received high attention from the country, and has invested a lot of manpower, material resources, and financial resources in this area to cultivate talents for the development of precision mechanical parts processing in China.

High precision machining is a mechanical processing method that achieves a machining accuracy of 1 micron. Precision machining is achieved in a specific and strict environment, with specified process specifications, using precision machine tools and precision measuring tools and instruments.

In recent years, automobiles, mold parts, and metal processing have mostly adopted a production form centered on CNC machine tools. When drilling holes, machining centers, CNC electrical machining machines, and other equipment are also mostly used. High speed and high-precision drilling has been put on the agenda. Regardless of the field of hole machining, achieving high precision and speed is an important competitive means to obtain user orders.

Precision machinery manufacturing includes the metal products industry, specialized equipment manufacturing industry, automobile manufacturing industry, railway, shipbuilding, aerospace and other transportation equipment manufacturing industry, electrical machinery and equipment manufacturing industry, computer, communication and other electronic equipment manufacturing industry, instrument and meter manufacturing industry, and so on. High precision machining technology has become the foundation of the current high-tech field, and improving the accuracy of ultra precision machining has become an urgent issue.
