Chapter 964 The knife coating is not as thicker as possible

"When did Wang Qingfeng hook up with the French again?" Yun Fei was surprised at what Deng Lanqing said.

Deng Lanqing shook his head: "Philip’s people are not willing to help us get these knives. In fact, their own company has this kind of hard material with 700 multi-layer nano coatings developed by the German Krupp Material Research Institute. Alloy tools, but they are unwilling to provide us with an excuse. After all, these tools are mainly used for super-precision machining and military manufacturing. They do not have the courage to violate the Wassenaar Agreement. Moreover, they do not want us to have precision manufacturing. After all, many of our country’s cutting-edge medical equipment are imported from their country..."

The Wassenaar Agreement stipulates not only advanced military technology, but also restricts the export of various advanced strategic technologies and technological equipment to China.

Yunfei wants to import from Pratt & Whitney the engines used in their most advanced civilian regional passenger jets for this reason.

After all, the United States is also one of the initiators of the blockade of China's advanced technology.

Especially now that China has not yet joined the World Trade Organization, the introduction of technologies in various advanced technology fields is basically impossible to achieve success.Only after China joins the World Trade Organization, these high-end technologies that can be extended to the military field will gradually be opened to China.

Even so, the most advanced things are still not available to China with money.

For example, Yunfei’s high-precision five-axis linkage and above are used to process some key components of aero-engines, as well as various advanced military materials. Unless China can produce it by itself, it will be the worst in the same level abroad. None of them will be exported to China.

"Sooner or later, we will no longer need these things from foreigners!" Yun Fei sighed.

No wonder this knife is so expensive. It costs $400 each without tax.

"Our material factory has been doing research on nano-coating materials and coating technology for so many years. It should have been successful long ago? After all, our research on coated tools is not much later than abroad. Time..." Zhang Hu also knew that the five-axis machining center of the September 1st Research Institute was about to be finalized in the past few days, and he was running here every three weeks. He hadn't thought that this time he would come across the mysterious Yun Feizheng. Holding a golden yellow milling cutter with the thickness of a small finger and observing it, when Deng Lanqing said that it was the most advanced cutter with a cost of four hundred dollars, her eyes were about to fall out.

This thing can't be eaten, it's just the outer layer of film, which is useless after use, especially the alloy matrix inside, it is useless.He has been to the Jiuyi Material Factory and its research institute many times, so he naturally knows where the key technologies of these coating materials are.

“It’s not too late for us to start, but for the precision machining technology of the base, we don’t have it in our country; we don’t have the material and technology of the substrate either; let alone the coating technology on the outside, the thickness of the coating on the outside of this tool is less than Three threads, but there are more than seven hundred layers, and we can only get one hundred and twenty layers..." Yun Fei sighed.

Some things, not only capital investment and early start can be more successful than others.

Just like their 32-bit chips, he had just arrived in Chengdu, and soon after he had Soviet technical experts in his hands, he quickly found them out. At that time, European and American countries were mainly using eight-bit chips to study 16-bit chips. Technology, but he dare not sell this chip technology to the world on a large scale, even in China, it is only used by himself and provided to the military for some research.

It's not that he doesn't know the benefits.

Not to mention his technical blockade of the entire world out of patriotism.

But foreign technology is far more advanced than China.Once they understand the principle and relying on their accumulated technical experience over the years, they can succeed in a short test. At that time, Yunfei will only have such a little technological lead.

Even after 16-bit chips have been introduced to the market in the past two years, they have not replaced 8-bit chip technology, mainly because the cost is too high and the technical advantages are not too prominent.Up to now, there are 32-bit chips on the market. Although the cost is now outrageous, it will not take more than two years to replace 16-bit chips and eight-bit chips.

This is the basis.

"Isn't it enough to make it thicker to achieve this kind of wear resistance?" With regard to technology, Zhang Hu is an amateur to the point where he can no longer be an amateur.

Hearing what he said, Deng Lanqing rolled her eyes and left. She was not ashamed to be with such a guy who didn't know how to pretend to understand, and even asked questions like a layman.

Yun Fei immediately looked at Zhang Hu and smiled bitterly: "I said Uncle Zhang, can your old man ask something a little more expert? Didn't you see that Mr. Deng disdain to stand with you? This question is really an idiot. Incomparably. If it is really easy, we will be short of tools?"

Zhang Hu suddenly became stunned.

He who is not a professional cannot understand the doorway inside.He immediately looked at Yun Fei in confusion, hoping to get an answer.

"Coated tools are not the thicker the coating, the better, the outer layer of coating is only to increase the wear resistance of the tool during the cutting process, especially the cutting edge, which is this position..." Yunfei alloy milling cutter in the handle He picked it up, pointed to the blade and introduced it to Zhang Hu.

Zhang Hu nodded: "I know this. The milling cutter is mainly used for cutting with this side edge. Don't assume that I don't understand anything. Just tell me why the coating can't be too thick... …"

Faced with Zhang Hu's look that I understand, Yun Fei was speechless.

This seems to be a common problem for the guys in the whole system, they all like to pretend they don't understand.

Who said that the main cutting of the milling cutter is to rely on the two side edges?Do you know that there are many special milling cutters that cut by the bottom edge?However, Yun Fei is too lazy to explain to Zhang Hu. It is very difficult for people who do not understand technology to explain these professional technical knowledge.

"These slaughter materials mainly use vapor deposition method or physical deposition method, or the two methods are used to coat the ion state and adhere to the substrate of the tool... Don't ask what is physical deposition method or vapor deposition method, you only You need to know that these are two different kinds of wear-resistant materials that can be glued to the tool base..." Yun Fei was a little speechless when he saw Zhang Hu's puzzled face and prepared to speak.

If Du Niang had grown up by this time, he would definitely let him ask Du Niang.

Zhang Hu nodded, even though it was like a mist in a cloud, he still didn't interrupt Yun Fei.

When he went to the September 1st Research Institute, those guys didn't explain this to him, maybe because they were afraid that it would be too laborious to explain, they didn't mention these professional terms at all.

"This coating is not as thicker as possible, because these wear-resistant materials are very hard and brittle, just like those ceramics, hard enough? But it is easy to crash. What's more, these coatings If the material is too thick, the cutting edge of the tool will become dull. For difficult-to-machine materials with good cutting toughness, you must ensure the sharpness of the blade..." Yun Fei explained to Zhang Hu for a long time, and finally let Zhang Hu understand paradoxically Why is the coating not thicker the better.

"In this way, the thickness of these coating materials is fixed. Within this fixed range, the more layers of coating, the better the wear resistance of these tools?" Zhang Hu finally asked. If he is competent, Yun Fei was just about to nod his head, let out a sigh of relief and then felt that he was not easy, Zhang Hu said something that made him go violently: "Oh, can't you just tell me this way? You have to show off your expertise in front of me, put me in the mist and tell me that the thinner the coating, the better, and the more the better..."

"I can't communicate happily with you..." Yun Fei was speechless.

"In other words, if Jiuyi Materials develops such a knife, it can be sold for four hundred dollars? Boy, you are a sign of getting rich!"

"Dream it. The German production cost of this thing will definitely not exceed one hundred dollars now, and with the improvement of craftsmanship and technological progress, it is possible that the price can be reduced to one or twenty dollars or even a few dollars. In this world, it is not only the Germans who are advanced in tool technology, but the Americans and Japanese have even better technology than them!" Yun Fei sighed.

Especially in Japan and the United States, the technology in this area is definitely not a boast, and the Chinese cannot admire it or not.

"Then they want to sell to us at such a high price?" Zhang Hu's question made Yun Fei go away completely.

"If we have such a technology in China, or if Europe and the United States do not block us, do you think we use some shameless methods to obtain these knives? Let's go back and see for yourself. The food in our canteen is better than your government canteen Far from it..." It seems that Deng Lanqing's departure is not unreasonable.

It's too hard to communicate with these people who don't understand technology.

"Now I know why I want to avoid him? Our domestic foundation is poor, which is not something our research institute and these supporting factories can do. He has to explain it to him every time he comes, making people's heads big." Seeing Yun Fei walking towards him as if he was about to eat people, while Zhang Hu was walking towards this side behind Yun Fei, Deng Lanqing immediately looked at Yun Fei with a sympathetic appearance.

"Let’s just ignore him, he likes how he likes. I don’t know what the big guys above think, how can he let him, a guy who doesn’t know much about technology, be in charge of industry and let him be in charge of economy Okay..."
