Several ultra-precision processing equipment from the Precision Instrument Research Institute were completely destroyed by the Germans. They not only burned the system but also destructively dismantled the equipment. The backup parts that Lin Johnson-Johnson owned were also destroyed by them.

Professor Dong Fang, who heard the news, rushed to the research institute in a hurry. He ran to the underground laboratory and saw the wreckage of the processing equipment that had been severely damaged. The air was filled with a strong acid smell. The Germans were still slamming. Two foreign engineers were wearing white protective suits and respirators, spraying gasoline on the debris.

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

A German walked up and pushed him away, shouting loudly at him and letting him go away, but Professor Dong Fang pulled the German as if he was crazy without taking a step back.

Gu Ming followed him and comforted him: "Professor Dong, you can't stay here anymore! These equipment can no longer be needed!"

Dong Fang grabbed Gu Ming's clothes and said painfully: "Why is this! The good equipment was ruined like this. Why is this?"

Gu Ming shook his head and said bitterly: "We have nothing to do, you'd better go up!"

Dong Fang pushed Gu Ming away with great force and said, "I want to go to find Lin Qiangsheng, and I want to ask him in person why he is so harmful to the equipment! Don't he know how important these high-quality and sophisticated processing equipment are!"

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

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

Dong Fang panted and looked at the headquarters building that was still quite far away. He stomped his feet and opened the door and got into the car.

Before he could sit down, Professor Dong Fang asked Gu Ming: "What did Lin Johnson think? How could he do this? What's the matter if foreigners destroy the machine? How could he do this!"

Gu Ming was very afraid that he would be angry with the old man if he said something. He waited for a while and said, "The German government discovered these precision processing equipment that the company had bought secretly. If the machine was not handed over to the Germans for processing, it would be very unfavorable to our company. Johnson and Johnson were under great pressure!"

Dong Fang beat the hammer and shouted angrily: "Then you can't let the Germans do this. You can find a way to save these machines and equipment! You can destroy these high-end equipment. This will cause great losses to the country!"

Gu Ming frowned, why did Dongxing's machine become a country, but he still said, considering that the old man was old, "Who made us not, and who made us unable to make it!"

"We don't have it? Me." Professor Dong Fang still wanted to argue. But after hearing Gu Ming's words, he was stunned for a moment, and finally he put down his hand with a lifting powerlessness.

"Oh, it's just a little bit!" Professor Dong Fang sighed deeply, and his body fell down on the backrest with a depressed look. He closed his eyes and covered his forehead with his hands, shook his head and said.

Gu Ming took Dong Fang to Lin Johnson's office, and the secretary told them that Lin Johnson was in the chairman's conference room. The two rushed to the conference room again and happened to see senior researcher Yang Wanli from the School of Engineering and arrived at the door panting.

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

Yang Wanli patted his old friend's shoulder and comforted him: "Let's watch it out. I believe that Lin Johnson is very sad like you and me, but who can't make such equipment in our country? If you don't have it, you have to be controlled by others. Haven't you and I seen too much in our life? Don't put too much pressure on Lin Johnson after entering, after all, he will definitely feel uncomfortable!"

Gu Ming looked at Yang Wanli and Dong Fang, and he bowed to the two and said, "Mr. Yang, Professor Dong. I, Gu Ming, thank you!"

Yang Wanli patted his shoulder and said, "We must help each other through difficulties!"

Professor Dong Fang nodded helplessly. After all, it is better than before. At least they have gained some insight into ultra-precision processing technology.

The three of them walked into the conference room and saw Lin Qiangsheng standing quietly in front of the windowsill with his back facing everyone. There were also Professor Xu Ranxue from the School of Engineering and Professor Li Guoxian from the University of Technology. The former was an expert in engineering planning and participated in many domestic key engineering construction and some important military engineering projects, and had made great achievements in the overall engineering construction; the latter was a leader in automation at the University of Technology, and was the first to set up a robot laboratory in China. Professor Li also participated in the teaching of automation in the aerospace major of the University of Technology, and was the leader in scientific research and technology in this area!

Lin Johnson invited them to help the two professors come up with ideas, how to continuously improve Dongxing's machining accuracy and find a way out for Dongxing's technological development strategy.

Foreign countries are also constantly improving processing accuracy. Although there is no such thing as industrial master machine, the four equipment in the laboratory are actually Dongxing Company's master machine!

Now that the mother machine is gone, the future path will be completely explored by yourself. In the morning, Lin Qiangsheng felt harsh. He thought that even if he grind, he would have to grind it with high precision, but in fact, it is not that simple. Ultra-precision and high-precision processing technology cannot be purely ground by manual grinding!

The machining accuracy of mechanical equipment will only be lost without increasing. Machinery with 1/100 mm accuracy can only process workpieces with an error of more than 1/100 mm. Therefore, even if the assembly error is not taken into account, the machinery assembled with mechanically machined parts with medium machining accuracy can only achieve low accuracy. To produce parts assembled into medium-precision machinery, it can only be made with high-precision processing machinery. According to this principle, to manufacture high-precision processing machinery, ultra-high-precision processing machinery can only be used.

This raises a question: how is the so-called "ultra-high-precision processing machinery" processed and manufactured.

The answer may be surprising, "ultra-high-precision processing machinery" is made by hand.

When it comes to "precision", it reminds people of technical terms such as "computer" and "CNC". In fact, accuracy has nothing to do with those fashionable nouns. Before those fashionable nouns appeared, humans could already achieve very high accuracy.

The most important influence on the accuracy of the processing machinery is the guide rail part. The moving part of the machinery 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 ultra-precision mechanical guide rails is called "absolute plane", and the accuracy is required to be above 1/10,000 mm. No machine can process such an absolute plane, and can only be processed manually.

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. Those patterns are the traces left by the swords of the craftsmen who made this plane.

Of course, human participation is very important but not all. Ultra-precision machining technology is an emerging comprehensive engineering science. It uses various advanced scientific and technological achievements in modern times to increase the accuracy of machining by 1 to 2 orders of magnitude. In the early 1980s, ultra-precision machining technology in developed countries such as the United States, Europe and Japan had reached 01 (100 nanometers), 001 microns (10 nanometers), and is moving towards 0001 microns (1 nanometers).

With the development of science and technology, the application of ultra-precision processing technology is becoming increasingly widespread. It can not only adapt to the development of cutting-edge products, such as automobiles, home appliances, and it electronics, but also widely used in the research and development of modern weapons. It can also drive the upgrading of general electromechanical products from low gear to high gear, which is a necessary condition for national industrial upgrading!

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

Therefore, it is not difficult to understand what Germany has done to Dongxing Company. Lin Johnson even thanked Americans for interfering with the German business department for not adopting a punitive policy of sanctioning against Dongxing Company, and the consequences will be even more serious!

Then, Dongxing Company's development is inseparable from ultra-precision processing technology. If you do not start catching up with the footsteps of developed countries now, you will be restrained step by step, and in the end your skills are not as good as others and lose the market!

The situation is very serious. With the reform and opening up of foreign countries, a large number of low-end technology products pouring into the country, these cheap technology products have made a lot of profits in China. In turn, foreigners invest the money earned from China in technological research and development. Their technology is becoming more and more advanced, but our market is filled with a large number of low-tech products, but their own products have no competitiveness and gradually withdraw from the market.

Once this worst case occurs, it will not only fill the country with low-end products, but also provide money for other people's technological upgrades, and it will also kill the domestic technological progress. If manufacturers cannot make money, they will not be able to do technical research and development. Without technology research and development, they will always have to buy other people's products and accept other people's technology.

If this continues, China will embark on a passive path of introduction and reintroduction. After being stifled by foreign technology, the Chinese market will only become the world of foreign technology!

For Dongxing Company, without super precision machining technology, let alone developing chip manufacturing equipment with high technical content, such as lithography machines, high-definition LCD technology, large-scale integrated circuit substrates, etc., everything is delusion!
