The general application fields of small-batch high-precision parts processing are: intelligent/automation equipment, intelligent robot (robot arm/cooperative robot/underwater robot/special robot), UAV, medical instruments, aviation, aerospace industry, shipbuilding industry, semiconductor industry, wind power generation, optical industry, 5G communications, construction machinery industry, machine tool industry, etc. The typical representative of mass production is the automobile industry, and the trial production of new models and engines in the automobile industry, as well as the mold industry, which mainly serves the processing and production of mass and high precision parts, still belongs to the single small batch production.

The composition of CNC machine tools, CNC machine tools, electronic computers, motor and drag, dynamic control, inspection and other technology as one of the automation machinery. The core structure of CNC machine tool includes control material, CNC machine tool device, servo control system, feedback device and machine tool itself.

With the development of CNC precision parts processing manufacturing industry, at the present stage of precision machinery and equipment processing has gradually to μm, submicron level of processing technology development, in the following processing, general machinery and equipment processing, high precision parts processing and ultra-high precision parts processing accuracy can be completed 1um.
