In recent years, the development of machinery manufacturing technology, production efficiency and technical accuracy continue to improve. Among them, the increase in production efficiency mainly from the application and improvement of automation, CNS is gradually changing to CIDIS, and has been used in some, played an important role, by the attention; and the increase in technical accuracy from the processing to super-processing of the change.
The development of machinery to make modern products more and more accurate, scale integrated circuit is the product of this background, its requirements will be hundreds of thousands of components or integrated in a square millimeter plane, line width of only 1μm, position error and shape error is less than 0.05μm, so the requirements of high machine precision, processing technology also need to be improved to meet the processing needs.
1 Types of machining
According to the characteristics and principles of different aspects, processing is mainly divided into four categories, namely, composite processing methods, special processing methods, abrasive processing methods and tool cutting processing methods.
In recent years, processing technology has also progressed, processing principle diversification, so in processing, mainly microfabrication, according to the characteristics of the parts and forming mechanism of different, processing is mainly divided into three, namely, deformation processing mode, combined with processing mode and removal processing mode. Deformation processing method, with the help of force, molecular movement, heat, etc. to make parts deformation, its shape, size, performance will usually change, the way including forging, casting, etc.; combined processing method, with the help of physical and chemical methods to other materials attached to, injected or welded in the surface of the parts, the way including welding, bonding, oxidation, electroplating, etc.; removal processing method, that is, separation processing method, with the help of light, electricity This method includes grinding, cutting, etc. In short, the processing method is no longer limited to traditional means, but adds new features such as deformation, stacking, etc. In addition, it also focuses on the surface treatment of the part, the creation of surface processing technology.

After the epidemic, is the Chinese machine tool industry happy or worried?
Nowadays, the phrase "keep a metre line, distance makes beauty" has become a popular Internet saying. Although the epidemic has shut down the opportunity for face-to-face communication, it has also opened up a new communication distance of "one metre" for us to live online. After the epidemic, is the Chinese machine tool industry happy or worried? On March 11th at 7pm, Machine Tool Business Network invites several experts from the machine tool industry to discuss the machine tool industry today and tomorrow with you.

What do cheap Chinese machine tools bring to manufacturing?
In recent years, the impression that Chinese machine tools are "cheap" has also been "deeply rooted". Now, "cheap" always seems to carry a bit of a pejorative meaning, and also makes China's machine tool industry quite criticized, but cheap is really bad? Cheap Chinese machine tools for the manufacturing industry and what has it brought?

Machine tool industry resumes work at 70%
At present, it is a critical period to fight against the new pneumonia epidemic and to promote the resumption of work and production in an orderly manner. After the Spring Festival holiday, especially since February 10, the situation of machinery industry enterprises resuming work and production has been rapidly increasing. The statistics department of the CTA has been monitoring the resumption of work by member companies on a daily basis. As of February 24, according to a survey conducted by the CTA on some of its members, the resumption rate reached over 77%, and the average resumption rate of employees of resumed enterprises was over 50%.
