Ultra-precision CNC Machining Machines: Leading by Technology and Diversifying
High-precision is the mainstream trend of CNC machine tools. In the past 30 years, the world-wide machine tool technology has been developed to a great extent. The development trend of machine tool technology has also exhibited diversified features, such as high-precision trends and high-speed motion. Trends, multi-movement axis trends, high reliability trends, multi-functional composite trends, reconfigurable trends, low-energy environmental protection trends, and smart trends. However, in all trends, the trend that best reflects the mainstream of development should be the trend of high precision and intelligence. Liu Bingye emphasized that high-precision is the mainstream development trend of CNC machine tools, and the precision of ultra-precision CNC machining tools is still an order of magnitude higher than that of precision machining.
The technical field involved in ultra-precision CNC machining technology is very rich. In the course of more than 30 years of research in the Beijing Institute of Machine Tools, Liu Bingye systematically summed up 36 key frontier studies and 11 leading core technologies for the related technologies involved in ultra-precision machining technologies. Among them, the key frontier research includes six aspects of design, moving parts, measurement analysis, process technology, host manufacturing technology and machine tool application condition technology. Leading core technologies include: manufacturing technology for key structures of super-precision spindles, key structure manufacturing technology for ultra-precision linear motion components, high-resolution motion drive technology, machining process manufacturing technology for machine tool key components, feature technology for external components to withstand external disturbances, and high Structure and manufacturing technology of stable and rapid linear motion, nested structure design technology of multi-axis machine tools, and integrated manufacturing technology of machine tools for target parts manufacturing.
A few days ago, the ultra-precision CNC processing equipment core technology capable of controlling one-thousandths of a millimeter of subtle movement has made a major breakthrough in China. This scientific and technological achievement of the national 863 key project with China's independent intellectual property rights has passed national-level appraisal in Zhejiang Shangyu. This means that China ranks among the international leaders in the manufacturing of ultra-precision processing equipment, which is of great significance for improving the overall level of China's manufacturing industry.
According to experts, the ability to manufacture ultra-precision CNC machine tools is an important symbol of manufacturing power. At present, only a few countries in the world have mastered these technologies. In order to improve the overall level of manufacturing, China has been actively exploring. The crankshaft follow-up grinding machine needs advanced technologies such as hydrostatic guide rails, trajectory control, and on-line measurement compensation. It can surpass the international advanced grinders of its kind in key technical indicators, and it is not easy. The core technology of this ultra-precision CNC machining equipment is an original breakthrough, which has practical significance in promoting the development of China's machine tool industry and improving the overall level of the manufacturing industry. Let us see the hope of a rapid increase in the level of the Chinese machine tool industry.
