CNC machine tools are the elite representatives of modern machine tools. Its large-scale production and use will undoubtedly make our production technology more sophisticated. Therefore, it is necessary to increase the numerical control rate of machine tools.
The number of ordinary machine tools is huge, and safety issues are highlighted. At present, most of the machine tools used in China are ordinary machine tools. Machinery, automobiles, motorcycles, railway machinery, mining machinery, agricultural machinery, petroleum, chemical industry, light industry, textile, shipbuilding, aviation industry, electronic equipment manufacturing, military industry, and other industries and fields retain ordinary cars, milling, planing, Milling, boring, stamping and other types of machine tools are about 4 million units. The movements and running parts of ordinary machine tools are usually bare, and they can easily cause accidents such as crushing, shearing, and collision. Personal safety problems have become a major obstacle to their development.
The economic growth of the industry is rapid and the growth structure is irrational. The economic growth of China's machine tool industry is rapid. In 2011, China produced a total of 860,000 metal cutting machine tools and 238,500 molding machines, achieving a total industrial output value of 660.65 billion yuan. In recent years, the numerical control rate of China's production machine tools has increased, but compared with the United States, Japan and other countries, the numerical control rate is at a relatively low level. Among them, the numerical control rate of metal cutting machine tools is about 30%, and the numerical control rate of forming machine tools Less than 7%. In 2011, China produced 860,000 metal cutting machine tools and 257,000 CNC machine tools. The output of CNC machine tools accounted for only 29.9% of the output of metal cutting machine tools, the production of 238,500 molding machines, and 15,000 CNC machine tools. Only 6.29% of the output of forming machines.
According to relevant data in our country, the number of machine tools officially put into use in China is about 8 million units, of which some old machine tools are eliminated at a rate of 3% each year, plus some other machine tools that are damaged due to accidents. The overall market is quite considerable. For these machine tools that need to be replaced every year, we must use new CNC machine tools as much as possible. Increasing the numerical control rate in the production process will also greatly contribute to the overall improvement of product quality.
At present, the research, development and application of numerical control technology are mainly concentrated in the numerical control machine tool industry, which has greatly promoted the development of China's CNC machine tool industry. The market share of domestically-manufactured numerical control systems in middle and low-end CNC machine tools has reached over 70%. However, in addition to CNC machine tools, mechanical products in other industries lack high-end CNC technology and equipment, and lack of high-efficiency numerical control products for specific processes. The numerical control rate of mechanical equipment is less than 20%, and most of them rely on foreign CNC systems. . Therefore, there is an urgent need to organize national-level CNC system companies and CNC technology promotion service organizations to intervene in a timely manner to upgrade the numerical control level of China's machinery and equipment, increase the market share of domestic CNC systems in machinery and equipment, and further promote the industrial upgrading of China's machinery and equipment. And the development of CNC system industry.
