At present, China's mechanical parts processing industry accounts for less than 30% of the total manufacturing industry, which is 5% lower than the average level of mechanical parts processing in the developed countries. This proportion has reached 41.9% in the United States, while Japan has reached 43.6%, which is close to the general level in Germany, 46.4%. China's top 500 manufacturing industries basically reflect the highest level of processing and manufacturing of mechanical parts in China. Among the top 500 manufacturing companies in China, the number of mechanical parts processing and manufacturing enterprises, sales revenue and profits accounted for 21 of the total manufacturing industry in China. %, 25.42%, 24.59%. These values are still lower than the level of machining of mechanical parts in developed countries.
Due to the backwardness of the manufacturing of mechanical parts, the value of various precision mechanical parts imported by China in recent years accounts for 50% of the total value of China's imports, and 2/3 of the processing equipment relies on imports, of which 100% of optical fiber manufacturing equipment generates electricity. 90% of equipment, 85% of integrated circuit chip manufacturing equipment, 70% of car industry equipment, CNC machine tools, textile machinery comes from imported products.
China's manufacturing and testing equipment in the field of mechanical parts processing and manufacturing, high-end CNC machine tools, high-end equipment, rockets, large aircraft, aero engines, automobiles and other key parts of the production line rely on imports. China's civil aviation existing large aircraft are all imported from foreign countries, there are more than 1,000. In the next few years, about 1,700 large aircraft will be needed, each selling for about $70 million, which will cost more than $100 billion.
High-precision mechanical parts processing products, the main reason for the high technical barriers lies in the more advanced parts, the higher the cost of CNC parts processing equipment. In the high-precision parts such as wafer manufacturing equipment, the proportion of imports is mainly due to thin film deposition (CVD), etching machine, and lithography machine. The three are the core equipment for CNC parts processing and manufacturing, CNC processing. The technical threshold is high, and the value of a single unit is large. The lithography machine is usually regarded as the largest capacity bottleneck of the fab, which is the core equipment of the micro-reduction process. In this respect, the Dutch ASML almost monopolizes the lithography field. Domestic precision machinery parts processing equipment manufacturers want to go beyond, there is still a long way to go.
