Fourth, the domestic gap in digital plasma cutting technology and foreign countries
90% of the cutting industry in developed countries is cutting CNC cutting machine, only 10% is manual cutting, while China's CNC cutting machine only accounts for less than 10% of the total amount of blanking, of which CNC plasma cutting ratio is smaller. Most of them still use manual or semi-automatic cutting, which is cumbersome and backward, labor intensive, low in production efficiency, and material waste is serious. Therefore, it is very necessary to develop and popularize CNC plasma cutting machines to change this backward situation.
Regarding the gap between domestic CNC cutting machines and foreign products, there is no big gap in the numerical control flame cutting machine, and the performance is relatively stable. Only the domestic cutting machine guarantees the quality, and some main components such as electromagnetic valve and pressure reducing valve. Imported parts are used in AC servo systems, and the quality of domestic parts is still unstable. The total performance of CNC plasma cutting machine is also similar to that of imported equipment. However, the plasma power supply matched with CNC plasma cutting machine has a larger gap with foreign countries. At present, many users are willing to use imported plasma power supply to explain the problem, so the development of CNC plasma cutting Related technologies are also very important.
In short, there is still a certain gap between domestic and imported from the quality of the incision and the durability of the wearing parts. Therefore, in order to completely replace the import, we must work hard on the production of the basic parts.
V. Market and application prospects
Before the early 1980s, the domestic market of CNC cutting machines was all occupied by foreign cutting machines. In the mid-to-late 1980s, domestic CNC cutting machines were gradually produced and put on the market. In the early 1990s, with the development of domestic CNC cutting machines, the market expanded rapidly. Forcing foreign companies to develop in China, the price of cutting machines has also dropped significantly. In the late 1990s, the quality of domestic CNC flame cutting machines has stabilized, and the price has dropped significantly compared with previous years. Therefore, imported machines have been gradually replaced.
As China's industry moves toward modernization, the demand for CNC cutting machines in the domestic market has increased year by year. In addition, due to the large number of CNC flame cutting machines in developed countries, the popularization of CNC plasma cutting machines is subject to certain restrictions. Machine technology started and applied late, forming a gap between supply and demand, which led to huge potential market for CNC cutting machines, especially CNC plasma cutting machines.
According to statistics, in recent years, the market demand for CNC plasma cutting machines in China is about 500 per year, and there is a trend of increasing year by year. The economic development of China's surrounding areas has shown us a good international market prospect. At present, the development trend of CNC plasma cutting machine should be developed in the direction of automatic, multi-functional, high-power and high-quality.
Conclusion
In the 21st century, China's CNC cutting industry faces various new challenges, and the international market is more competitive. We should aim at the world's advanced level, continuously develop new products, and promote the general improvement of the domestic technical level in the same industry. Only in this way can we eliminate low-grade and inferior products, purify the market, and drive industry manufacturers to change their business philosophy. At the same time, we must strengthen scientific research and development and technological innovation. Working hard with quality management, China's CNC cutting industry has quickly reached the world's advanced level, thereby revitalizing national industry and improving China's overall national strength.
