Behind the hottest development experience of China

  • Detail

Behind the development experience of China's machine tools is the country's deep pain, and its status must be changed.

manufacturing and processing technology is very important for a country, especially in the era of increasingly relying on science and technology. Without advanced machine tools, even if you have a good idea, it is just an idea, which cannot become a reality. Sometimes it is not design, but basic technology that restricts more

there is an example. In the 1980s, the Soviet Union bought four high-precision machine tools from Japan. Then the United States found that the Soviet submarine that had been closely monitored had disappeared under its nose, and the monitoring system that had been built at a huge cost had turned into a useless blind man

from this example, we can see that whether there are national standards for machine tools is of great importance to national security. But sadly, China's current advanced machine tools are all imported from abroad, and the precision and quality of our own machine tools simply cannot compete with the world's advanced counterparts

Japan once announced that China would not be able to produce advanced weapons without Japan. Unfortunately, this is not pure nonsense. China really depends on Japanese machine tools. Of course, polyurethane, high-performance organofluorine, silicone, advanced ceramics, special glass, high-performance glass fiber, high-performance aluminum alloy, graphene and other fields have high technical levels. We can also buy from other countries, but we can't hide the fact that our processing technology is weak

from the perspective of electrical performance, in the 1990s, when China bought machine tools, other countries tried to cheat more money, such as dividing a machine tool into multiple parts and selling it at a high price, and requiring monitoring of its use. It is not allowed to produce weapons, just like robbery, but China has to accept these conditions

now China has been trying to solve this dilemma. For example, it requires that the R & D expenses of relevant units should not be less than 5% of sales, while in some important fields, such as aerospace, automobile, etc., it requires domestic machine tools to account for more than 70%, forcing relevant enterprises to make progress. Now this situation has finally been alleviated
