Popularization of NC Machine tool Technology in an all-round way

Date:2018-6-26 Author: admin

CNC machine tool technology started in the 1950s. In 1952, the Massachusetts Institute of Technology (MIT) developed the world's first CNC milling machine. Due to the constraints of basic technology, CNC machine tool technology has not been widely used and popularized in the next 20 years or so. Until the early 1970s, the advent of large-scale integrated circuit (LSI) and microprocessor (CPU) promoted the rapid development of microelectronics technology, and created conditions for large-scale manufacturing and wide commercial application of CNC machine tools. In the middle and late 1970s, CNC machine tool technology entered a period of rapid development. in the late 1970s and early 1980s, the United States, Europe, Japan and other countries have realized the intergenerational upgrading of machine tool product technology, that is, CNC machine tool. For example, Yamazaki Mazak (YamazakiMAZAK) Company of Japan realized the complete numerical control of machine tool products in 1982. It is not too late for the research and development of CNC machine tool technology in China. in 1958, Tsinghua University and Beijing No.1 Machine tool Factory cooperated in the development of China's first CNC lifting table milling machine (using separate component technology). It's only six years later than the world's first CNC machine tool. However, in the following 20 years, the technological progress of CNC machine tools in China was very slow. in addition to the constraints of technical factors, the interference and destruction of the Cultural Revolution was also an important reason. Since 1973, the state has organized numerical control technology to tackle key problems, but until the beginning of reform and opening up, in addition to manufacturing a small number of numerical control wire cutting machines with relatively simple technology, CNC machine tools as a whole are still stuck in the stage of technology research and development. Far behind by the West.

Since the reform and opening up, CNC machine tool technology has been the main direction of the machine tool industry. In 1980, the Beijing Machine tool Research Institute introduced CNC system technology from Japan's Fanako (FANUC) Company through license transfer. subsequently, starting from the sixth five-year Plan (1981 ~ 1985), the state organized several consecutive five-year plans to tackle the key problems of CNC technology. It has promoted the development and progress of NC machine tool technology. But even so, the process of industrialization of CNC machine tools is still slow.Until the end of the last century, the numerical control rate of the output value of China's machine tool industry is still hovering at about 20%, and the numerical control rate of output is less than 10%. The real maturity and rapid popularization of CNC machine tool technology in China began in this century. In the period of rapid development of machine tool industry, the technology of numerical control machine tool is popularized rapidly, the output is increasing rapidly, and the numerical control rate continues to improve.According to the China Machine tool and tool Industry Association, since 2013, the numerical control rate of machine tool industry output and the numerical control rate of consumption in the machine tool market have exceeded 70%, and reached a level of nearly 80% in 2016. At present, in the field of machine tool industry, all kinds of machine tools suitable for using numerical control technology have adopted numerical control technology, and there are no technical obstacles. The same situation is also reflected in the current field of machine tool users, machine tool users can easily recruit skilled CNC machine tool operators in the labor market, while ordinary machine tool operators have become scarce resources. We have basically realized the comprehensive popularization of CNC machine tool technology at the manufacturing end and the application end.Although the products of CNC machine tools in our country are still in the middle and low level as a whole, which is more than 30 years later than that of western developed countries, our country has entered the era of CNC machine tools in an all-round way, which is a great historical achievement. It is worth noting that the value-added tax policy of CNC machine tool products, which was implemented by the state in 1999 and lasted for 10 years, has played an important role in promoting the realization of the above intergenerational upgrading.The source network of this article, if there is infringement, please contact to delete.
