Three minutes to talk about popular science
In the Japanese population, Japanese machine tools seem to have become an indispensable tool for China's development. China's military, industry, and economy rely on the import of Japan's cutting-edge technology - machine tools.
So is that really the case?Is our country's own machine tool really so vulnerable?
Compared with other machines, machine tools have an unusually important position, and are called"Industrial machine tools".Machine tools, machines that make machines, and machines that make machine tools. It is undoubtedly the heart of the industrial system and the key to manufacturing and production.
At the beginning, China's machine tool industry can even be described as miserableDomestic machine tools can only do one meter, and they can't process anything at all, and the number can be counted, 950,000 units. China's machine tool industry is completely in the embryonic state, and China's vast land and resources have become completely inversely proportional.
Although China began to increase investment in machine tool factories in the future, everyone knows a truth, Rome was not built in a day. It is also unrealistic to wait completely for the development of our own machine tool industryTherefore, in the early days, China had to import machine tools from abroad to meet the needs of development.
In the early days of reform and opening up, China's machine tool industry finally began to take shapeThe original plan distribution model has been unable to meet the market demand, and began to play "order advertising". This is undoubtedly good news.
Can be struck one after the other,Western countries have entered the era of CNC machine tools with high processing accuracy, stable processing quality, high productivity, intelligence and modernization.
At this time, the Japanese machine tool industry, benefiting from long-term training and development, has been completely in the forefront of the world, even the world's first.
Since 1889, Japan has been engaged in machine tool manufacturing, and is the third country after the United States and Germany to establish a machine tool industry. From manual ordinary machine tools at the beginning, to high-efficiency automatic machine tools, to small and medium-sized automatic CNC machine tools.
In 1982, Japan's machine tool output value surpassed the United States and Germany by a slight margin to become the world's first.
In 1987, Japan's CNC machine tool output also successfully surpassed that of the United States.
If you fall behind, you will be beaten," and no one understands this truth better than ourselves. In order not to repeat the same rut, we can only continue to choose to import foreign machine toolsEven high-end CNC machine tools once reached 80% of the import proportion.
In order to change this situation, countless engineers have resolutely devoted themselves to the machine tool industry, hoping that our country will be able to catch up one day.
High-end CNC machine tools are not just simple machinery. It is a strategic material, and it is even related to the security of a country.
In aerospace, manufacturing and other fields, a slight error will be extremely fatal. And to avoid these errors, only the most high-end CNC machine tools can do it, and Japan obviously can.
The curved wings of the Boeing 787 show the level of manufacturing of Japanese machine tools. Wingspan 601 meter, the wingtips can be bent upwards up to 79 meters.
It is true that Japan has a certain authority in the machine tool industry, so is it completely correct for the Japanese to say that China relies on Japanese machine tools?
The answer, of course, is not.
After China's vigorous development and continuous investment, China's machine tool industry is also not what it used to be. Since 2009, the scale of China's machine tool manufacturing industry has basically ranked first in the world. Today, the total output of China's machine tool industry also accounts for a quarter of the world's total output.
In 2022, the production volume of machine tools in China will already rank first in the world.
At the same time, as a symbol of high-end technology, the continuous breakthrough of CNC machine tool technology is also the goal that China has been pursuing.
In China's largest CNC machine tool R&D and production area, in the past year alone, more than 10 key technologies have been conquered. The spindle speed has also increased from 2,000 rpm to 8,000 rpm step by step.
Not only that, but as the core component on the machine tool, it is also one of the most vulnerable parts of the guide railOur country has been able to quench parts up to 11 meters long.
In accordance with international standards, China's Shenyang machine tool gantry series products have reached the level of precisionSuccessfully crossed 001 mm threshold, and is exported overseas.
And at the China International Hi-tech Fair held this year,China's domestic five-axis high-end CNC system debuted in front of the world for the first time.
The domestic high-end CNC system realizes micron-level precision motion control, providing real and reliable support for China's aerospace, new energy vehicle manufacturing and other industries.
Realistically speaking, in the low-end machine tools, China is very competitive in the world. In terms of ordinary machine tools, China has been second to none;The mid-range machine tools are in competition with each other.
China's machine tool industry is also the world's most complete variety, the most complete industrial chain.
However, we also have to admit that in terms of high-end machine tools, there is still a gap between China's machine tools and the world's top level, but it is not as completely dependent on imports as described in Japan.
Due to congenital deficiencies, coupled with the continuous targeting of some Western countries, China's machine tool industry is completely in the blockade of all parties to kill a "bloody road".
The real core technology cannot be bought, we can only study it ourselves, and we know this better than anyone else. With the efforts of countless people, the domestic machine tool industry has also begun to see the light of day.
In the first half of this year, China has canceled 76 billion Japanese machine tool orders, and in contrast, the number of machine tools imported by Japan from China has increased a lotAfter a large number of Chinese machine tools poured into the Japanese market, many Japanese companies lost a lot of profits.
Not only that, with the increasing improvement of China's talent training, industrial development and economic support, the machine tool industry is no longer an empty phrase to catch up and even complete the counterattack.
We cannot be arrogant, and we need not be arrogant. It is true that we still have many shortcomings, but the development trend of our country is shocking to any country in the world. What we lack now is the accumulation of time, and we believe that in the near future, we will catch up.
