Several ultra-precision machining equipment at the Institute of Precision Instruments were completely destroyed by the Germans, who not only burned down the system but also dismantled the equipment destructively, and those spare parts owned by Lin Qiangsheng were also destroyed by them.

Professor Dong Fang, who heard the news, rushed to the institute in a hurry, and he ran to the underground laboratory to see the wreckage of processing equipment that had been seriously damaged, a strong acid smell wafting in the air, the Germans were still clanging, and two foreign engineers wearing white protective suits and respirators were spraying gasoline on the mutilation.

"Stop, stop!" Professor Dong Fang's eyes were torn, and he shouted loudly and ran forward to stop these people from continuing to destroy.

A German stepped forward and pushed him away, shouting at him to go away, but Professor Dong Fang did not retreat and pulled the German like crazy.

Gu Ming ran down and comforted: "Professor Dong, go up, you can't stay here!" These devices are no longer available! ”

Dong Fang grabbed Gu Ming's clothes and said bitterly: "Why is this! Good equipment is ruined like this, why is that? ”

Gu Ming shook his head and said bitterly: "We can't help it, you better go up!" ”

Dong Fang pushed Gu Ming away vigorously and said, "I'm going to find Lin Qiangsheng, I'm going to ask him face-to-face, why is the equipment so bad!" Doesn't he know how important these high-precision processing equipment are! ”

The old professor stumbled out of the institute and walked towards the East Star Building. Gu Ming looked at the old professor's stumbling back and sighed heavily.

"Professor Dong, I'll send you over." Gu Ming ordered people to look at the Germans below, and then drove the car to catch up with Dong Fang.

Dong Fang panted and looked at the headquarters building still a long way away, he stomped his foot to open the door and get into the car.

Before he could sit down, Professor Dong Fang asked Gu Ming: "What does Lin Qiangsheng think, how can he do this?" What's the matter with letting foreigners destroy the machine, how can anyone do that! ”

Gu Ming was afraid that what he said would make the old man angry. He waited for a while and said: "The German government has found these precision machining equipment that the company has secretly bought, if we don't hand over the machine to the Germans, it will be very unfavorable to our company, and Johnson & Johnson is also under a lot of pressure!" ”

Dong Fang slapped his thigh and shouted angrily: "Then you can't let the Germans do this, and you have to keep these machines and equipment by finding a way!" You let people destroy these high-tech equipment, which is a great loss to the country! ”

Gu Ming frowned, how could the machine of the Eastern Star become a country. But considering the old man's age, he still said: "Who let us not have it, who made it impossible for us to make it!" ”

"We don't? I" Professor Dong Fang still wanted to theorize, but after hearing Gu Ming's words, he was stunned for a moment, and finally his raised hand was weakly put down.

"Alas, just a little!" Professor Dong Fang sighed deeply, his body fell on the backrest, he closed his eyes tightly, covered his head with his hands, and kept shaking his head and said.

Gu Ming took Dong Fang to Lin Qiangsheng's office, and the secretary told them that Lin Qiangsheng was in the chairman's conference room, and the two rushed to the conference room just in time to see Yang Wanli, a senior researcher from the School of Engineering, also panting to the door.

"Old Yang, those machines are ruined! If the equipment is still there, we can't say that we can quickly reach the level of dimensional accuracy of 1 micron. As long as a few key points are overcome, we can catch up with the technical level of those equipment! Professor Dong Fang stomped his feet heavily and said painfully.

Yang Wanli patted his old friend on the shoulder and comforted: "Look at it, I believe that Lin Qiangsheng is very sad like you and me, but who made our country unable to build such equipment!" If you don't, you have to be controlled by others, haven't you and I seen too many experiences in this life, don't put too much pressure on Lin Qiangsheng after entering, after all, his heart must not be comfortable! ”

Gu Ming looked at Yang Wanli and Dong Fang, he bowed and said to the two, "Yang Gong, Professor Dong." Thank you, Guming! ”

Yang Wanli patted him on the shoulder and said, "Let's help each other get through the difficulties together!" ”

Professor Dong Fang also nodded helplessly, after all, it is better than before to say it now. At the very least, they already have some eyebrows for ultra-precision machining technology.

The three of them walked into the conference room and saw Lin Qiangsheng standing quietly in front of the windowsill with his back to everyone. Also on the seat are Professor Xu Ranxue of the School of Engineering and Professor Li Guoxian of the University of Technology, the former is an expert in engineering planning, has participated in many domestic key engineering construction and some important military engineering projects, and has made deep achievements in the overall construction of the project; The latter is a leader in the automation major of the University of Technology, and took the lead in establishing a robotics laboratory in China, and Professor Li also participated in the teaching of aerospace automation at the University of Technology. He is a leader in scientific research and technology in this field!

Lin Qiangsheng invited them to let the two professors come up with ideas on how to continuously improve the machining accuracy of Dongxing and find a way out for Dongxing's scientific and technological development strategy.

Foreign countries are also constantly improving the processing accuracy, although there is no industrial machine tool, but the four equipment in the laboratory is actually the mother machine of Dongxing Company!

Now the mother machine is gone. The way forward is to be explored entirely on your own. In the morning, Lin Qiangsheng was ruthless, thinking that even if he grinded, he had to grind out high precision, but in fact, of course, it was not that simple, and ultra-precision and high-precision machining technology could not be purely manually grinded!

The machining accuracy of mechanical equipment will only be lost and not increased, and the machine with an accuracy of 1/100 mm can only process workpieces with an error of more than 1/100 mm. Therefore, even if a machine is assembled using parts machined with medium machining accuracy without considering the assembly error, it can only achieve low accuracy, and parts assembled into medium-precision machinery can only be manufactured using high-precision processing machinery. According to this reason, the only way to manufacture high-precision processing machinery is to use ultra-high-precision processing machinery.

This raises the question of how the so-called "ultra-high-precision processing machinery" is manufactured.

The answer may come as a surprise to you: "ultra-high-precision processing machines" are made by hand.

When it comes to "precision", it is very reminiscent of technical terms such as "computer" and "numerical control", in fact, precision has nothing to do with those fashionable terms, before the emergence of those fashionable terms, human beings can already achieve high precision.

The guide part has the greatest impact on the accuracy of the machining machine. The movement part of the machine is limited by the guide rail, and the accuracy of the guide rail directly determines the accuracy of the mechanical movement.

The sliding surface of the ultra-precision mechanical guide rail is called "absolute plane", which requires an accuracy of more than 1/10,000 mm, and no machine can process this absolute plane, which can only be processed by hand.

Anyone who has seen the sliding surface of the guide rail of a high-precision machine tool knows that the so-called "absolute plane" is not a smooth mirror, but a plane full of regular patterns, and those patterns are the traces left by the shovel blade of the craftsman who made this plane.

Of course, human participation is the main but not the whole story, and ultra-precision machining technology is an emerging comprehensive engineering science. It is the use of various advanced scientific and technological achievements in modern times to improve the machining accuracy by 1~2 orders of magnitude. In the early 80s, the ultra-precision machining technology of developed countries such as the United States, Europe and Japan has reached 0.1 (100 nanometers) and 0.01 microns (10 nanometers), and is moving towards 0.001 microns (1 nanometer).

With the development of science and technology, the application of ultra-precision machining technology is becoming more and more extensive. It can not only adapt to the development of cutting-edge products, such as automobiles, home appliances, IT electronics and other high-tech, but also widely used in the research and development of modern weapons, and can drive the general mechanical and electrical products from low gear to high gear upgrading, is a necessary condition for national industrial upgrading!

Therefore, foreign countries attach great importance to ultra-precision machining technology. The United States, Britain, Japan and other countries regard ultra-precision machining technology as the lifeline of their own scientific and technological development strategies, and strictly block it as a top-secret technology!

Therefore, it is not difficult to understand what Germany has done to Dongxing, and Lin Qiangsheng even has to thank the Americans for their interference, and the German business sector has not made a punitive policy of sanctions against Dongxing, and the consequences are even more serious!

Then, the development of Dongxing company is inseparable from ultra-precision machining technology, if you do not start to catch up with the footsteps of developed countries now, you will be restricted step by step, and finally the technology is not as good as people lose the market!

The situation is very serious, with the reform and opening up of a large number of low-end technology products from abroad poured into the country, these cheap technology products made a lot of profits at home. On the other hand, foreigners reinvest the money they earn from China in technology research and development, and their technology is becoming more and more advanced, but our market is flooded with a large number of low-tech products, and their own products are not competitive and gradually withdraw from the market.

Once this worst-case scenario occurs, it not only floods the country with low-end products, but also provides money for people's technological upgrades, and this also stifles the pace of domestic scientific and technological progress. If manufacturers can't make money, they can't engage in technology research and development, and without technology research and development, they will always have to buy other people's products and accept other people's technology.

In the long run, China will embark on a passive road of introduction and re-introduction, and after being stifled by foreign technology to its own enthusiasm for scientific research, the Chinese market can only become the world of foreign technology!

And for Dongxing Company, there is no ultra-precision processing technology, let alone the development of high-tech chip manufacturing equipment, such as what lithography machine, high-definition liquid crystal technology, large-scale integrated circuit substrates, etc., everything is delusional!
