Present situation and future development forecast of precision machining

The development of advanced technologies such as precision machining in China is of great significance to China's mechanism and manufacturing. In terms of design, computer aided design (CAD) is popularized. In terms of application, various high and new technologies have developed rapidly and achieved remarkable results. In terms of management, the research and practice of the new production mode has its own characteristics, which has promoted the technological progress and management modernization of China's manufacturing industry. Technology has been greatly developed in precision machining, and precision machining will make the manufacturing process more efficient. In this way, our production and development will enter a "virtuous cycle mode".


In the past two decades, the machinery manufacturing industry is developing towards precision machining and ultra precision machining with a rapid pace of development. In the future development process, precision machining and ultra precision machining will become the key technology to win in international competition and market competition. The development of modern manufacturing industry is committed to improving machining accuracy. The main reason is to improve the performance and quality of products; Improve its quality stability and performance reliability, promote product miniaturization, strong functionality, good parts interchangeability, high product assembly and commissioning productivity, and promote manufacturing and assembly automation. With the development of manufacturing industry, precision machining is now developing from micron and submicron processes. In the future, the precision of ordinary machining, precision machining and ultra precision machining can reach 1um, 0.01um and 0.001um respectively. Moreover, precision machining is moving towards atomic machining precision. With the continuous improvement of limit precision, It not only creates conditions for the development and progress of science and technology, but also provides a good material means for mechanical cold machining.


Mechanical manufacturing technology has developed rapidly from improving precision and productivity at the same time. In terms of improving productivity, improving the degree of automation is the development direction of all countries. In recent years, from CNC to CIMS has developed rapidly and has been applied in a certain range. In terms of improving precision, from precision machining to ultra precision machining, this is also the development direction of major developed countries in the world. Cutting has been widely used in many fields, because the requirements of mechanical manufacturing for output have decreased, and the requirements for size and shape have gradually increased. Precision machining has a new development trend. Using lathes requires different turning methods. However, grinding, gear cutting, milling and other processes can be carried out in one lathe. The development trend of process integration is more significant.
