In today's world of CNC machine tools, industrialized countries attach great importance to the machine tool industry, and are competing to develop advanced machine tools with mechatronics, high precision, high efficiency and high automation to accelerate the development of industry and national economy. For a long time, Europe, the United States and Asia have competed fiercely with each other in the international market, and an invisible front has been formed. Especially with the advancement of microelectronics and computer technology, the development of CNC machine tools has accelerated since the 1980s. Multiple demands have already become the focus of machine tool manufacturers from all over the world competing to display advanced technology, compete for users and expand the market at the four major international machine tool exhibitions. After China's accession to the WTO, it has formally participated in the fierce competition in the world market. How to strengthen the strength of the machine tool industry and accelerate the development of the CNC machine tool industry is an urgent and arduous task.
Technical characteristics and development conditions of high-precision CNC lathes
In 1948, the U.S. Air Force provided equipment research funds for the manufacture of aircraft miscellaneous parts. G&L and MIT cooperated with MIT for four years of research. In 1952, the world's first CNC milling machine was trial-produced, and 100 of them were immediately delivered to the military. In terms of results, it shows that it is the crystallization of social needs, scientific and technological level, and personnel quality; in terms of technology, it shows a huge innovation in the control of mechatronics machine tools.
Technical characteristics of CNC machine tools
CNC machine tools have the following three outstanding characteristics:
Using binary math input, the machining process can be programmed arbitrarily, the spindle and feed speed can be changed according to the needs of the machining process, and multi-coordinate linkage can be realized, making it easy to process miscellaneous surfaces. The processing object has the characteristics of "changeable, changeable and fickle", and it is convenient to change batches and adjust, which can realize the flexible production of small and medium-sized batches of miscellaneous parts and various varieties, and meet the needs of the society for product diversification. However, the price is relatively expensive, and the economic rationality of its use needs to be properly analyzed;
The combination of hardware and software can realize information feedback, compensation, automatic acceleration and deceleration and other functions, which can further improve the machining accuracy, efficiency and automation of the machine tool;
It is a mechatronics machine tool mainly based on electronic control, which gives full play to the unique advantages of microelectronics and computer technology, and is easy to realize informatization, intelligence and networking, and can easily form various advanced manufacturing systems, such as FMS, FTL , FA, and even the future CIMS, can maximize industrial productivity, labor productivity.
