Status Quo and Future Development Forecast of Precision Machining

The development of advanced technologies such as precision machining in China is of great significance to my country'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 model has its own characteristics, which has promoted the technological progress and management modernization of my country's manufacturing industry. Technology has been greatly developed in precision machining, and precision machining has made the manufacturing process more efficient, so that our production and development will enter a 'virtuous cycle mode'.

In the past two decades, the machinery manufacturing industry has been developing towards precision machining and ultra-precision machining at a rapid pace of development. 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 is committed to improving machining accuracy, the main reason is to improve the performance and quality of products; improve the stability of its quality and reliability of performance, promote product miniaturization, strong functionality, and good parts interchangeability , The assembly and debugging of products have high productivity, and promote the automation of manufacturing and assembly. With the development of the manufacturing industry, the current precision machining is developing from micron and sub-micron processes. In the future, the precision of ordinary machining, precision machining and ultra-precision machining can reach 1Um, 0.01um, 0.001um, respectively. Moreover, precision machining is progressing towards atomic-level machining accuracy. With the continuous improvement of ultimate accuracy, conditions have been created for the development and progress of science and technology, and it also provides a good material means for mechanical cold working.

To mechanical manufacturing technology from the two aspects of improving precision and productivity have developed rapidly at the same time. In terms of improving productivity, improving the degree of automation is the direction that countries are committed to developing. In recent years, from CNC to CIMS has developed rapidly and has been applied to a certain extent. From the aspect of improving precision, from precision machining to ultra-precision machining, this is also the case. The development direction of the major developed countries in the world. Machining has been widely used in many fields, because the current requirements of mechanical manufacturing for output have decreased, and the requirements for size and shape have gradually increased, and precision machining has a new development trend. The use of lathes requires different turning processing methods. However, processes such as grinding, gear cutting, and milling can be carried out on one lathe. The development trend of this process integration is more significant.
