The development of precision machining and other technologies in China is of great significance for the mechanical manufacturing institutions and machinery manufacturing industry. In the field of design, computer design (CAD) has gained popularity, and at the application level, various high-tech technologies have rapidly developed and have achieved significant results. In terms of management, the research and practice of new production models have driven the modernization of technological progress and management in China's manufacturing industry based on their characteristics, and processing technology has greatly developed in precision mechanical processing. Precision machining enables manufacturing processes to be more efficient, so that our production and development will enter a "virtuous cycle" mode.
In the past two decades, the mechanical manufacturing industry has developed rapidly towards precision machining and ultra precision machining. In the future, precision machining and ultra precision machining will become key technologies to win in international competition and market competition. The main reason why modern manufacturing is committed to improving processing accuracy is to improve the performance and quality of products, enhance the stability and reliability of their quality, and promote the miniaturization and functionality of products. The interchangeability of components is good, and the productivity of product assembly and debugging is high, promoting the automation of manufacturing and assembly. With the development of the manufacturing industry, precision machining is gradually moving towards micron and submicron level processes. In future processing, ordinary machining, precision machining, and ultra precision machining can achieve 1 μ m, 0.01 μ m, and 0.001 μ m respectively, and precision machining is moving towards atomic level machining accuracy. With the continuous improvement of ultimate accuracy, in order to promote the development of science and technology and improve manufacturing conditions, it also provides a good material means for mechanical cold processing.
Mechanical processing technology needs to be developed simultaneously from both improving accuracy and production efficiency. In terms of improving processing efficiency, improving automation is currently a direction that every country is developing simultaneously. In recent years, the development from CNC to CIMS has been very rapid and has been applied to a certain extent. In terms of improving accuracy, the development from precision machining to ultra precision machining is also a new direction for governance and development in major developed countries around the world. Cutting machining has been applied in multiple fields.
Due to the current downward trend in production requirements for mechanical manufacturing, and the gradual increase in requirements for size and shape, precision mechanical processing has developed into a new trend. The use of lathes requires the use of different turning methods. However, grinding, gear cutting, milling and other processes can be integrated on a single device, and the development trend of this process integration is the most obvious.
