Manufacturing industry is the core industry of modern industrial system, the technical level of manufacturing industry reflects a country's scientific and technological level, international competitiveness and comprehensive national strength; Manufacturing products can be widely used in national defense, medical, aerospace, transportation, electronics and other military and civilian fields, is the world's industrial powers generally focus on support and development of the industry.

However, China's manufacturing industry is facing a "big but not strong" situation, compared with the world's manufacturing power there is a big gap, which is one of the more prominent performance is the processing capacity of precision machining supporting parts backward. The precision parts of precision machining are generally the core parts of the whole machine product, and are the guarantee of the function of the whole machine product, so the precision parts have very high requirements in terms of quality, consistency, durability and so on.

The number of fine machining manufacturers in China is huge, and the technical level and processing capacity are different. Although some domestic supporting processing manufacturers can meet the processing quality requirements of precision parts by purchasing advanced production equipment, it is often difficult to maintain the stability and consistency of product quality under the condition of mass production and cost control.

To achieve high-quality processing and manufacturing in mass production, it is not only necessary to have advanced production equipment and other hardware equipment, but also to design and implement scientific and reasonable production technology according to the product characteristics of the components and customer needs, balance the constraints of processing quality, product delivery and cost control, and realize the optimal combination of production resources such as equipment, tools and personnel. At the same time, in order to ensure the effective execution of the production process, the processing manufacturer also needs to establish a perfect quality control system and equip a well-disciplined production team.
