Now, an old engineer with a hot temper stood up and looked at Liu Feng without any hesitation:

"It's not that we are shirking responsibility. Our five-axis CNC center has represented the most advanced level of the Chinese machine tool industry! We have looked at the drawings. The processing accuracy is not difficult than the vector engine of the j-20. We also operate strictly according to the corresponding standards. There is no reason why even the accuracy of the vector engine can be achieved, but this thing always has problems!"

"The reason is obvious, either the materials you provide are unqualified, or your design is immature and cannot meet the design requirements at all!"

"Who are you?"

"This is Cao Wansheng, Mr. Cao from our machining center, a top expert in the five-axis CNC center, and a level 9-level turning worker..." The person in charge introduced Liu Feng with a wry smile.

Level 9 turning worker?

Liu Feng was stunned. This was a national treasure-level great figure!

No wonder he has such a hot temper...

"Old Cao, there should be no problem with the design drawings and materials."

"Then what you mean is that there is something wrong with our processing center?" The old man sneered, "Since that's the case, you should ask Gao Ming. Maybe the Chinese and Chinese people can process your things."

Liu Feng: “…”

He has a really big temper!

Seeing that Liu Feng was so angry that he couldn't speak, Academician Chen Xuedong, who was standing beside him, quickly spoke:

"Mr. Cao, can't our five-axis CNC center be processed? You also know that in the field of high-end equipment manufacturing, we are indeed much worse than Europe, especially high-end machine tools. For the same five-axis CNC center, the processing accuracy of others is indeed much higher than ours."

really.

On the surface, China has become the world's largest machine tool producer. The machine tool output value became the world's first in 2009, and has remained the world's first in recent years. But what about it?

Last year (1 year), China's total machine tool imports were about US$10.1 billion, but the total exports were only 2.7 billion. Can you imagine that a country that claims to be the world's largest machine tool country has a total import of machine tools four times the total export!

What is the problem? Isn’t it because we export all mid- and low-end products, while we import all high-end CNC machine tools?

Especially when the five-axis CNC center is not sold to us, we can have such a huge entry!

Although China can also develop its own five-axis CNC center to solve the problem of existence or not, the gap with foreign countries is quite obvious, especially when Europe already has a higher-end seven-axis CNC center...

"The problem of machine tools is not understandable. After all, we can even process vector engines with stricter accuracy. There is no reason why we don't meet the standards when processing these things of yours!" Another old man with a little gray hair stood up and retorted.

"This is Qian Gaoxuan, Mr. Qian, and our top expert, a level 9 fitter..." The person in charge continued to introduce with a wry smile.

Chen Xuedong looked at him curiously. He didn't expect that there were so many top technicians in the 606 Institute, and he suddenly felt a little relieved. Could it be that it was their reason?

"This is not necessarily the case. After all, our design and vector engine are still different..."

"It's clear that there is something wrong with your materials!"

"It's so ridiculous. I really can't understand. We can process materials with higher precision. How can we put them on you? They have never been qualified?"

"Yes, although our five-axis machining center is worse than that of Europe, it is enough for us to use it ourselves. It is absolutely impossible for the machine tool to make it happen!"

Chen Xuedong couldn't speak directly.

Seeing the situation moving in an out of control, the person in charge opened his mouth, but had no way to control the situation.

"Ahem, let me say a few words."

At this time, Academician Qiao stood up.

After all, he was the head of the Institute 606. After seeing this old man, most of the people standing here calmed down their discussion with great confidence.

"Let's just let's not care about who it is. The most important thing now is to solve the problem, right? This engine is related to the national aerospace engineering. To a certain extent, it is even more important than the j-20. Therefore, I hope everyone will not shirke the responsibility, find the foundation in a realistic way, and solve the problem..."

"That's right," Huang Qihui also stood up at the right time. He looked at it just now with a headache. "I understand the feelings of all the old men for our five-axis machining center. I don't want others to have any doubts. I also understand Professor Liu, you have confidence in yourself, but in doing research, you must seek practical things in the end. Everyone discusses friendly and discusses friendly..."

Whispers suddenly sounded in the processing center.

After hearing the words of the two, many people were a little unhappy. You two are both from the 606 Institute, so why did you support outsiders?

What Professor Liu, and what about the winner of the explosives award?

I'm not a machine tool, can I understand better than them?!

However, Liu Feng, who was also listening, was not unhappy.

Faced with the doubts of these old men, Liu Feng shrugged and did not change his confidence at all: "Let's do this, I don't know the situation here. We will process it on site again, maybe it's because of other reasons that have not been discovered?"

Mr. Cao laughed rather than angry and said, "Okay, okay, if you can really find other reasons, or it is simply because of our processing center, I will immediately accept you as your teacher!"

"Then there is no need," Liu Feng smiled and sighed, "You can almost be my grandfather, but I dare not be your elder."

"Hmph!" The old man snorted coldly, "Stop talking nonsense, be willing to accept the loss! When will it start?"

"Time doesn't wait for anyone, just now!"

"Okay, I'll let you give up!"

As he said that, the old man opened an idle five-axis CNC machine tool and ordered people to prepare all the materials and operate them proficiently. While operating, he also explained it to the outside world. That means you can see that my operation steps are fine.

Of course, the other old experts nodded in a flash. As for Academician Qiao, the head of the processing center, Mr. Huang, Chen Xuedong and others, they naturally smiled bitterly. They were really hot-tempered and started to do anything at all!

But there is no way to stop it.

However, just as the old man finished the test run and was about to put the materials on the operating table, Liu Feng suddenly shouted: "Let's wait!"

"What's wrong? Is there a problem?" Cao Gong frowned and turned his head, "Don't worry, if there is a problem with the machine tool operation or program, Lao Qian and the others will not protect me."

"I still believe there is no problem with the operation level of all the masters," Liu Feng smiled, but he secretly complained in his heart. Even if there is a problem, we can't understand it, so what are you saying?

Of course, they are all top masters, so there shouldn't be such low-level mistakes.

Continuing, "I want to take a look at your processing materials first."

"Okay, you can see it yourself!"

"This should be the production material of No. 1 large item, right?"

Liu Feng murmured to himself while checking the materials on the loading table.

The No. 1 large piece is the most critical "carbon layer" structure of the "carbon sail". It is a large curved surface that is approximately elliptical. The surface tolerance needs to be processed to a level less than a trace. After all, a layer of u-25 coating is required to be applied on it, which is naturally quite strict. Therefore, it is also the large piece with the most "problems" in the five-axis machining center.

"That's right, it's this thing." Cao Gong nodded.

"Well, that's OK, I'm fine."

After observing carefully for a while, Liu Feng nodded and confirmed.

His superpower ability has already reached an incredible level. He only needs to "look" to feed back the microscopic conditions of the material into his mind. He doesn't know how much order of magnitude is needed than the most advanced scanning tunnel microscopes and any other detection methods.

He had just confirmed that the state of the "carbon layer" structure is completely in line with his original design requirements for this material.

However, according to these top machining masters, it is unlikely to be a problem with processing operations. So, where is the problem?

...

It is no exaggeration to say that after so many failed processing, the cost of each component of the antimatter engine prototype has reached an unbearable level. At least, the price is no lower than that of a gem of the same weight!

It can only be said that as the crown of human industry, the industrial flower of engines is truly well-deserved.

Of course, scientific research is just burning money. Whether it is Liu Feng or the senior management, they are actually prepared for this. Therefore, even if the money-burning speed of antimatter engine projects exceeds that of power generation projects, no one has ever said anything.

At least, compared with decades of huge investment in aircraft engines, the development of antimatter engines can be considered extremely "cheap".

Beijing Dynamics Research Institute.

Standing in the factory in the assembly center, when he saw the parts transported from Station 606 gradually assembled into finished products, Chen Xuedong finally couldn't help but stand on the loading table, stroked the pulse energy engine with a dark and shiny luster on the table, and sighed.

"It's really not easy."

Standing under the loading table, Liu Feng nodded in agreement:

"It's really not easy. More than 50 billion yuan was invested, nearly a thousand supporting manufacturers, with a total of more than 100,000 people working together. On the 606 stations, the scrap materials piled up could be piled up into a gold medal. This was why such a prototype was successfully created! If I had given me another chance, I would never have wanted to make such a thing again."

That's right, in order to get this thing out first, he almost mobilized the capable force of the entire Power Engineering Institute, and even the research and development progress of high-energy particle engines had to be postponed for this. The entire Power Research Institute, from Liu Feng to the most ordinary researcher, has hardly had a full sleep in the past few months!

Is it easy for them?

Academician Jin Donghan, who was standing by, also sighed: "Yes, it's not easy, but our efforts are worth it. With this thing, the future is firmly in our hands! To be honest, it's really unbelievable that we can really create this thing in just 9 months!"

Chen Xuedong didn't say anything, but the expression on his face was no more calm than this one.

Compared to Jin Donghan, who was devoted to engine development from the beginning, he was able to feel the kind of luck and full of accomplishment from this moment.

If Liu Feng hadn't remembered him at the beginning, or had made a mistake when making a choice, he would not know who would have gained all this!

At this moment, in addition to his full admiration for Liu Feng, his heart was filled with gratitude, grateful for his kindness of knowing and for allowing him to experience all this. If it weren't for the last step of "test drive" that was not completed, he would have taken Liu Feng to drink and celebrated!

The dreamy look was read from the faces of the two academicians, but Liu Feng shook his head and said:

"It's been nearly a year, so I can only say that I can barely pass. With such a large investment and so many big guys working together to solve the problem, it has been delayed for so long. It seems that it is because our basic industry is too weak and not strong!"

"If it were replaced by a seven-axis linkage CNC center of Chinese people, perhaps there would be no twists and turns from the day the drawings were determined. People could directly discover the problem when processing materials, and how could so many things happen!"

Chen Xuedong also nodded. He was the 606th institute that he went to with Liu Feng. He witnessed with his own eyes how the "problem" that seemed to have no problems on both sides was cracked. Naturally, he understood what Liu Feng was talking about.

"There is no way, the precision machine tool manufacturing industry abroad has entered the micro-nano era, and can also integrate information technology, system control technology, electronic technology, optoelectronic technology, communication technology, sensing technology, software technology and expert systems. However, our country has not even achieved the era of mid- and low-end CNC integration, and as early as the 1980s, Ou and Toray have already done it!"

"In the key technologies for developing high-end CNC machine tools, such as high-speed, high-precision motion control technology, dynamic, thermal comprehensive compensation technology, multi-axis linkage and composite processing technology, intelligent control technology, high-precision direct drive technology and reliability technology, etc., in combination, we are at least 0 years behind Western countries! It is really difficult, difficult, and too difficult to improve basic industries!"

"Is that true?" After hearing Academician Chen's feelings, Liu Feng hesitated for a moment, looked at the engine, thought carefully for a while, and said, "I think that compared to pulse energy engines, the development of high-end machine tools is relatively simple."

Chen Xuedong: “…”
