Usually, the air purification level of ultra-precision machining must reach 100~10000. Cleaning is the most common air purification method, and the purified processing workshop is called a clean room or an ultra-clean room. Generally speaking, there are two main types of purification, one is overall purification and the other is local purification. Local purification is economical, and purification is achieved by allowing positive pressure clean air to flow into local processing areas such as the workbench, preventing the inflow of outside air. Since the hair and work clothes of the staff may bring dust, before entering the work, the staff must clean the outdoor and replace the special clothes, and be wet by the wind, so as to effectively avoid the impact of dust on the processing quality.
The impact analysis of the processing mechanism is that new technologies and new equipment have been emerging in recent years, and precision machining should also continue to increase research efforts and explore new processing methods. In terms of traditional machining, ultra-precision machining, precision high-speed machining, precision grinding belt grinding, abrasive machining, etc. of diamond tools have achieved good results; in terms of non-traditional machining, laser beam, electron beam and ion Beam and other high-energy beam precision machining, ultrasonic machining, electrical discharge machining and electrochemical machining have obvious advantages, especially the application of combined machining methods, such as ultrasonic honing, electrolytic grinding and other technologies. The significance of its breakthrough development lies in the main performance In the clear proposal of removal processing, the effective integration of processing and deformation processing, especially the advantages of superimposed processing rapid prototyping, has a very important role in promoting the development of processing technology.
In essence, the purpose of ultra-precision machining is to achieve the processing limit. Over time, with the development of science and technology, this limitation is also changing, requiring long-term exploration and research. Therefore, how to adhere to the "evolutionary machining principle", by using mechanical equipment with lower machining accuracy, using advanced process technology, computer servo, special measuring tools, etc., can directly and indirectly meet production needs, and directly affect precision machining or ultra-precision machining parts overall quality. Obviously, the machining mechanism is the foundation of the machining method, the key to the development of ultra-precision machining technology and theoretical innovation, and plays an important role in the overall effect of parts machining. With the development of the industrial industry, new technologies and new equipment are continuously innovated, and the level of machining accuracy has been greatly improved.
Super cnc precision machining technology has gradually become a concrete manifestation of comprehensive national strength, and is the driving force for the development of cutting-edge technology, national defense, microelectronics and other industries. Therefore, in-depth research on the processing mechanism, processing materials, processing equipment and other factors that affect the quality of ultra-precision machined parts is carried out to continuously reduce machining errors and improve the machining accuracy of parts, so as to provide a reliable driving force for the implementation of the development strategy of an industrial powerhouse.
