What is precision NC machining and automation equipment for?
Numerical control technology is the foundation and core of advanced manufacturing. Since the establishment of numerical control technology in the middle of the 20th century, it has brought revolutionary changes to the machinery manufacturing industry. Now, numerical control technology has become the technical basis for manufacturing industry to realize automation, flexibility and integrated production. Modern advanced manufacturing technologies such as CAD / CAM, FMS, CIMS, agile manufacturing and intelligent manufacturing are all based on NC technology. Through the development of numerical control technology and the establishment of numerical control machine tool industry, all industrial developed countries in the world have promoted the mechanical processing industry to step into a new historical development stage, which has brought great changes to the structure of the national economy.
CNC machine tool is also an important basic equipment of Electromechanical industry. It is also a means of production modernization of pillar industries such as automobile, motorcycle, aerospace, mould, machine tool and electronics. CNC machine tools are also an important part of the world's third industrial revolution. The output value of CNC machine tool industry itself is far less than that of automobile, aerospace and other industries, but high-efficiency CNC machine tools have brought high benefit growth and modern production mode to the manufacturing industry, which is a huge source of power to promote the development of national economy. In particular, the expansion and extension of numerical control technology in the manufacturing industry has brought profound changes to the industrial structure, product structure, specialized division of labor, machining mode and management mode, social production division of labor, enterprise operation mechanism and so on. The related industries based on it are important basic industries related to the national strategic position and reflecting the level of national comprehensive national strength. Its technical level has become an important symbol to measure the level of a country's industrial modernization.
CNC machine tool is an electromechanical product integrating electronic information technology and flow machine tool technology. It is an essential complex production tool for the development of machine manufacturing industry and the whole industry. It is not only a factor of productivity, but also an important commodity. CNC machine tools have the characteristics of high efficiency, precision, flexible automation and easy realization of process compounding and information integration. They are especially suitable for processing complex shapes and parts and flexible production of small and medium batches and varieties. Therefore, it has become the most important basic equipment of modern advanced manufacturing technology and the color flow product in the world machine tool market. Numerical control rate is an important symbol of the modernization level of a country's manufacturing industry. The development of numerical control processing technology directly affects the improvement of manufacturing technology level of various departments of the national economy. CNC machine tools are the basis of factory automation. The popularization of CNC machine tools will bring great changes to modern manufacturing technology. The development of numerical control machine tools in industrial developed countries has generally experienced three stages: slow, rapid construction and guaranteed development. At present, it has reached a high level. The numerical control ratio of machine tool output value has exceeded 50%, and the numerical control rate of metal cutting machine tools is higher. In addition, the numerical loss rate of metal cutting machine tool output value in Japan in 2000 was 88.5%.
At present, there are about 14 million machine tools in the world, of which more than 1 million are CNC machine tools, accounting for about 7% ~ 8%. The annual output of machine tools in the world is 1 million. There are about 200000 CNC machine tools, accounting for 20%. With the development of microelectronics and computer technology, the number and variety of CNC machine tools will continue to increase in the future. CNC entertainment will be more widely used in the whole machine manufacturing industry. At the same time, with the fierce competition in the world market, there is no doubt that the requirements of domestic and international markets for NC machine tools will increase day by day. The development of NC machine tools is very large, and the development prospect of NC machine tools is very broad.
