Precision machining is a process in which the size or characteristics of a workpiece is changed by processing machinery. Precision machining is generally used in the production of complex parts and the assembly of products. The main applications are automotive, communication products, aviation, medical and other industries.

In recent years, the mechanical manufacturing process has developed rapidly, and the productivity and process accuracy have been continuously improved. Among them, the increase in productivity mainly comes from the use and improvement of automation, and the increase in process accuracy comes from the change from precision machining to ultra-precision machining.

With the development of automation in the economic system, the efficiency of precision machining cannot be separated from the automation of equipment. The micro-devices needed in the optoelectronic information, micro-electronic machinery and other industries, as well as the large-scale optoelectronic devices and ultra-precision processing equipment that need to be built in the aerospace, aviation and other industries, all have high requirements for their automation and automation. The introduction of automated equipment can increase the stability of processing and reduce the dependence of processing results on manual experience.

The precision machining industry is developing in the direction of higher precision. In the future, more and more automated precision machining equipment will be put on the market. Outsourcing may become more and more common in the precision machining market, especially in the high-end market.
