Present situation and future development forecast of precision machining
The development of advanced technologies such as precision machining is of great significance to our country's mechanism and manufacturing. In terms of design, computer-aided design (CAD) is popularized. In terms of application, various high-tech 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, so that our production and development will enter a virtuous circle mode.
In the past twenty years, the machinery manufacturing industry has been developing rapidly towards precision machining and ultra-precision machining. In the future development process, precision machining and ultra-precision machining will become the key technologies 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 the stability of quality and reliability of performance, promote the miniaturization of products, strong functionality, good interchangeability of parts, high productivity of product assembly and debugging, and promote the automation of manufacturing and assembly. With the development of manufacturing industry, the present precision machining is developing from micron and submicron processes. In the future processing, the precision of general machining, precision machining and ultra-precision machining can reach 1Um, 0.01um and 0.001um respectively, and precision machining is progressing towards atomic machining precision. With the continuous improvement of extreme precision, it creates conditions for the development and progress of science and technology, and also provides a good material means for mechanical cold processing.
Mechanical manufacturing technology has developed rapidly from two aspects: improving accuracy and productivity. In terms of improving productivity, improving automation is the development direction of all countries. In recent years, CNC to CIMS has developed rapidly, and it has been applied in a certain range. In terms of improving precision, it has developed from precision machining to ultra-precision machining, which is also the development direction of major developed countries in the world. Machining has been widely used in many fields, because at present, the demand for output of mechanical manufacturing has declined, the demand for size and shape has gradually increased, and precision machining has a new development trend. Using lathes requires different turning methods. However, grinding, gear cutting, milling and other processes can always be carried out in one lathe, and the development trend of this process integration is obvious.
