Dalian precision machining is an important manufacturing process that is widely used and has great potential. Against the backdrop of continuously promoting industrial automation and intelligence, precision machining will further develop and provide better component processing services for manufacturing industries in various industries. At the same time, we should also strengthen the research and development of precision machining technology and talent cultivation to improve the competitiveness of China's manufacturing industry.

Precision machining technology mainly includes CNC machining, ultra precision machining, grinding machining, and etching machining. CNC machining refers to the use of computer-controlled CNC machine tools for machining, which control the movement of the machine tool and the position and path of cutting tools through programming to achieve high-precision machining of parts. Ultra precision machining is a machining technology that can achieve sub micron level accuracy requirements, mainly used in the manufacturing of optical components and electronic devices. Grinding processing is a method of machining achieved through the interaction between abrasive particles and workpieces, suitable for materials with high hardness and complex shaped parts. Etching processing is the use of chemical substances to corrode the surface of workpieces, achieving the processing of parts with specific shapes and sizes.

What is the core technology of precision machining in Dalian?

High precision machining technology. Precision machining requires high-precision machining of workpieces, which requires maintaining high-precision process control during the machining process, improving the dynamic stability and static accuracy of the machining machine, and effectively controlling factors such as thermal deformation during the machining process. At the same time, a series of measures need to be taken, such as reducing temperature changes during the machining process, controlling the wear of cutting tools, and improving feedback control of machining accuracy, to ensure the stability and accuracy of machining accuracy.

Secondly, advanced processing equipment and processes. Precision machining requires advanced processing equipment and processes to achieve. This type of processing equipment needs to have the characteristics of high precision, high rigidity, and high stability to ensure the accuracy of the processing process. At the same time, advanced machining techniques such as high-speed cutting, ultra precision grinding, ultrasonic machining, etc. are also needed to improve machining quality and efficiency.

Thirdly, technological innovation and optimization. Precision machining requires continuous process innovation and optimization to improve machining accuracy and efficiency. This includes researching new machining processes and methods, exploring new machining materials and cutting tools, and optimizing the selection of machining parameters. By continuously improving the process, errors and deformations during the machining process can be reduced, and the accuracy and stability of the machining can be improved.

The development of precision machining cannot be separated from the support of advanced mechanical equipment and process control technology. The application of modern CNC machine tools, ultra precision machining equipment, and automated production lines enables precision machining to achieve higher machining accuracy and production efficiency. At the same time, precision machining is constantly innovating and developing, and various new processing technologies and equipment have been developed, such as laser processing, electrochemical machining, and electrical discharge machining, providing more choices and possibilities for the development of the manufacturing industry.

Precision machining also requires the use of auxiliary equipment and tools, such as fixtures, measuring instruments, lubricants, etc. Fixtures are used to fix workpieces and ensure stability and accuracy during the machining process. Measurement instruments are used to measure the machining results to ensure that the size and shape of the processed parts meet the requirements. In addition, the use of lubricants can reduce friction and heat during the cutting process, improve process stability and cutting efficiency.
