At present, the machining accuracy of precision CNC machining parts is mainly divided into precision and ultra-precision. Its machining accuracy ranges from micrometers to submicrometer, and even nanometers. It is widely used in the high-tech fields of automobiles, home appliances, IT, electronics, and military and civilian industries. At the same time, the development of precision and ultra-precision processing technology has also promoted the development of machinery, molds, hydraulics, electronics, semiconductors, optics, sensors and measurement technology, and the metal processing industry.

Development Trend of Processing Technology of Precision CNC machining parts.
Generally, according to the machining accuracy of precision CNC machined parts, the machining of precision CNC machined parts can be divided into three stages: general machining, precision machining, and ultra-precision machining. At present, precision machining refers to a machining technology with a machining accuracy of 1~0.1μm and a surface roughness of Ra0.1~0.01μm. However, this limit is constantly changing with the advancement of precision CNC machining parts. Today's precision Processing may be the general processing of tomorrow. The problems to be solved in the production of precision CNC machined parts are processing accuracy, including form and position tolerance, dimensional accuracy, and surface condition; second, processing efficiency. Some processing can achieve better processing accuracy, but it is difficult to achieve high processing efficiency. Precision machining includes processing technologies such as micro-machining, ultra-fine processing, and finishing.
Ultra-precision machining is a process of micro-cutting materials on ultra-precision machine tools and using the strictly constrained relative movement between parts and tools to obtain extremely high shape accuracy and surface finish. The current ultra-precision machining refers to the machining technology in which the dimensional accuracy of the precision CNC machined parts is higher than 0.1 μm, the surface roughness Ra is less than 0.025 μm, and the resolution and repeatability of the positioning accuracy of the machine tool used are higher than 0.01 μm, also known as It is a sub-micron level processing technology and is developing towards nano-level processing technology. Ultra-precision processing includes processing technologies such as micro-processing, ultra-micro processing, smoothing, and finishing.
After decades of hard work in the direction of precision and ultra-precision machining, precision CNC machining parts are becoming more and more mature. Whether it is ultra-precision machine tools, diamond tools, or ultra-precision machining processes, a complete set of ultra-precision manufacturing technology systems has been formed. Precision CNC machining parts have laid the foundation for a higher level of development, and now it is moving towards nanometer precision or nanometer precision, and its prospects are very encouraging. With the rapid development of science and technology and increasingly fierce market competition, more and more manufacturing industries have begun to invest a large amount of human, financial, and material resources into the research and implementation strategies of advanced manufacturing technologies and advanced manufacturing models.
The development trend of precision machining technology facing the 21st century is reflected in the following aspects:
1. Precision; the core of precision machining is mainly reflected in the requirements for dimensional accuracy, profiling accuracy, and surface quality. At present, the precision of precision EDM has been comprehensively improved, the size processing requirements can reach ±2-3μm, the bottom corner R-value can be less than 0.03mm, and the best-processed surface roughness can be less than Ra0.3μm. By adopting a series of advanced processing technologies and process methods, the mirror processing effect can be achieved and the EDM processing of high-precision mold parts such as micro connectors, IC plastic packaging, mobile phones, CD boxes, etc. can be completed.
2. Informatization; information, material, and energy are the three elements of the manufacturing system. With the application of computer, automation, and communication network technology in manufacturing systems, the role of information is becoming more and more important. The information input in the product manufacturing process has become a major factor in determining product costs. The essence of the manufacturing process is the collection, input, processing, and processing of various information resources in the manufacturing process. The final product can be regarded as the material manifestation of information. Therefore, information can be regarded as an industry, including in manufacturing. Among. For this reason, some companies have begun to use network technology, computer networking, information highways, and satellite data transmission to realize off-site production. Make production dispersed and networked to meet the needs of highly flexible production in the 21st century.
3. Integration; the role of integration is to integrate multiple unit systems that were originally running independently into a new system that can coordinate work and have stronger functions. Integration is not a simple connection, it is achieved through unified planning and design, analysis of the functions and relationships of the original unit system, and optimization and reorganization. The purpose of integration is to realize the functional integration of the manufacturing enterprise. The functional integration must rely on modern management technology, computer technology, automation technology, and information technology to achieve technical integration. At the same time, it must also emphasize the integration of people. Since there is no human in the system, the system is running. The effect of the company’s business philosophy, operating mechanism, and management model are all related to people. In addition to technical integration, the integration of management and people should also be emphasized. Integrated production will become the dominant mode of production facing the 21st century.
