Manufacturing and computing are the foundations of modern industry.
5G, semiconductors, chips, and lithography machines in the computing field have attracted much attention, and have entered public opinion from the industry in just a few years; on the other hand, the manufacturing field seems to have failed to attract the same attention. Cars and horses are left out in the cold. However, manufacturing is the foundation of a country's development. Even the computing itself, which people talk about, its main goal is to empower manufacturing.
The most basic tool in the manufacturing industry is the machine tool, known as the "industrial machine tool". Although the GDP contributed by the machine tool industry accounts for less than 0.3% of the total, its importance cannot be measured only by economic data, especially the five-axis CNC machine tool, which is known as the "heavy weapon of the country", has a very high strategic position.
How important is the five-axis CNC machine tool? Why is such an important machine slowly fading out of the market's vision?
The important weapon of the country, the tortuous development If only four words are used to describe the importance of machine tools, the "Toshiba incident" is worthy of this task.
In the "Toshiba Incident" that caused a sensation in the world in 1987, the Japanese company Toshiba, for violating the ban, sent MBP-four 110S five-axis CNC boring and milling machines to the enemy country, the Soviet Union, which significantly reduced the noise of the propellers of Soviet submarines and warships, directly affecting the Soviet Union. Comparison of sea power. Therefore, Japan's Toshiba was sanctioned by the United States, and its products were banned from entering the United States. The ban lasted for as long as three years, and the losses were immeasurable.
The influence of five-axis CNC machine tools on the country's military power was undoubtedly revealed in the "Toshiba incident". Not only that, it also plays a pivotal role in high-end fields such as aviation, aerospace, scientific research, precision instruments, and high-precision medical equipment.
In the general-purpose field of the people, the importance of machine tools as the mother of all machines is self-evident. It can not only help factories speed up production, but also has applications in almost every branch of modern industry. There are many downstream fields, and it is the starting point of most industrial manufacturing.
Therefore, the machine tool industry has always been an important strategic layout point for major countries and leading companies.
The United States has successively proposed the implementation of the "Advanced Manufacturing Partnership Program" and the "National Strategic Plan for Advanced Manufacturing" to develop advanced manufacturing and technology; Germany has proposed a blueprint for the development of Industry 4.0, and is committed to taking cyber-physical systems as the core and smart factories as the carrier. , develop German Industry 4.0, and position it as a technology platform for a new round of industrial revolution; Japan has announced a blueprint for its industrial structure, identifying 10 cutting-edge technology fields, and relying on this to strengthen domestic manufacturing. These policies are for its own Lay a solid foundation for the development of machine tools.
China is no exception. Not long after the founding of New China, the strategic deployment of the machine tool industry was made.
In 1952, the Central Ministry of Heavy Industry established the idea of professional division of labor and set up a shelf for the development of machine tools: a total of 18 machine tool factories were established to clarify the division of labor; at the same time, 8 comprehensive research institutes were also established to support the development of national machine tools; not only In this way, the country still believes that the research and development strength is not enough, and it has allocated 37 professional research institutes and enterprise design departments, forming the second wall of defense for the scientific research and development system of the machine tool industry.
In 2009, the "04 Special Project" launched by China arranged a total of 562 related topics, invested 9.114 billion yuan in financial funds, applied for a total of 3,956 invention patents, established 407 national and industry standards, and developed 2,951 new products and new technologies , The new output value is about 70.6 billion yuan.
Perhaps in the short term, China's machine tool industry may not be able to catch up with Germany and Japan, but the machine tool industry will still be a strategic battleground for the Chinese government. In the past, there was the "04 Special Project", and recently there was "Made in China 2025", and there may be more in the future. Much support. China's machine tool industry is expected to grow slowly in this environment, and eventually it will be able to independently produce good machine tools comparable to Germany and Japan. A number of benchmark machine tool companies have also emerged in China to participate in the global competition for high-end machine tools.

What is domestic CNC lathe system?
At present, domestic CNC lathe systems are becoming more and more high-tech. CNC systems include open-loop servo systems, closed-loop servo systems, semi-closed-loop servo systems and CNC servo systems. The mechanical structure of the feed system of domestic CNC machine tools is very different from that of ordinary machine tools, which is reflected in the use of precision ball screw pairs, gap elimination mechanisms, and precise guide rails (such as linear guide rails, hydrostatic guide rails, plastic guide rails, etc.) wait). The position detection device is the key to ensure the accuracy of closed-loop and semi-closed-loop servo systems. Commonly used position detection devices include resolvers, inductive synchronizers, gratings, and magnetic gratings.

Numerical control machine tool fault analysis and maintenance experience summary
The application of CNC machine tools is becoming more and more extensive. It has good processing flexibility, high precision and high production efficiency, and has many advantages. However, as the technology is becoming more and more advanced and complex, the quality requirements of maintenance personnel are very high, and they are required to have deep professional knowledge and rich maintenance experience, so that they can be eliminated in time when the CNC machine tool breaks down.
