The Current Situation and Future Development Forecast of Precision Mechanical Processing

　The development status of advanced technologies such as precision machining in China is of great significance for China's machinery institutions and manufacturing. In terms of design, computer aided design (CAD) has become popular. In terms of application, various high-tech technologies have developed rapidly and achieved significant results. In terms of management, the research and practice of new production forms have unique characteristics, promoting technological progress and management modernization in China's manufacturing industry. Technology has been greatly developed in precision machining, which in turn enables manufacturing processes to be more efficient. In this way, our production and development will enter a "virtuous cycle".



In the past two decades, the mechanical manufacturing industry has been rapidly developing towards precision machining and ultra precision machining. In the future, precision machining and ultra precision machining will become key technologies to win in international and market competition. The modern manufacturing industry is committed to improving machining accuracy, mainly due to the improvement of product performance and quality; Improve the stability of its quality and reliability of its performance, promote product miniaturization, strong functionality, good interchangeability of parts, high production rate of product assembly and debugging, and promote manufacturing assembly automation. With the development of the manufacturing industry, precision machining is now being carried out from micron and submicron level processes. In future machining, the precision and ultra precision machining accuracy of general machining can reach 1Um, 0.01um, and 0.001um, respectively. Moreover, precision machining is advancing towards atomic level machining accuracy. With the continuous progress of extreme precision, conditions have been created for the development and progress of science and technology, It also provides outstanding material means for mechanical cold processing.



To the rapid development of mechanical manufacturing technology from both improving accuracy and production rate. In terms of improving production rates, improving automation is the direction that countries are committed to. In recent years, the development from CNC to CIMS has been rapid and has been applied within a certain range. In terms of improving precision, from precision machining to ultra precision machining, this is also the direction that major developed countries in the world are committed to. Cutting machining has been widely applied in multiple fields, as the current demand for production in mechanical manufacturing has decreased, while the demand for size and shape has gradually increased. Precision machining has shown a new trend. The use of a lathe requires different machining methods for turning, but grinding, gear cutting, milling, and other processes can be carried out on a single lathe, and the trend of integrating this process is significant.
