1002 Tool coating is not as thick as possible

"When did Wang Qingfeng hook up with the French again?" Yun Fei was very surprised by 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 cemented carbide with 700 layers of nano-coating developed by the Krupp Institute of Materials Research in Germany. tools, but they excuse that they are unwilling to provide them to us. After all, these tools are mainly used for super-precision machining and military manufacturing. They have not dared to violate the Wassenaar Agreement. What's more, they don't want us to have precision-made Ability, after all, many cutting-edge medical equipment in our country 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.

This is also the reason why Yunfei wants to import the engines used in their most advanced civilian regional airliners from Pratt & Whitney.

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, it is basically impossible to succeed in technology introduction in various advanced technology fields.Only after China joined 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 something that China can't buy even if it has money.

For example, in Yunfei's world, the high-precision five-axis linkage and above are used to process some key components of aero-engines, as well as various advanced military materials. None will be exported to China.

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

No wonder the knives are so expensive, [-] dollars excluding tax.

"Our material factory has been doing research on nano-coating materials and coating processes for so many years. It should have been successful a long time ago, right? After all, we are not much later than foreign countries in the research of coated tools. Time..." Zhang Hu also knew that the five-axis machining center of Jiuyi Research Institute was about to be finalized in the past few days, and he was running here every now and then.He hadn't imagined that when he came this time, he would meet Yun Fei, who was elusive and elusive, who was observing with a golden milling cutter as thick as a little finger. He couldn't help but roll his eyes when he heard Deng Lanqing say that it was a state-of-the-art cutting tool costing $[-] apiece. It's about to fall out.

This thing can't be eaten, it's just a layer of film on the outside, it's useless after use, especially the alloy matrix inside, it's useless.He has been to 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 we don't have the precision machining technology of the base. We don't have it in China; we don't have the material technology of the substrate either; not to mention the coating technology on the outside. The coating thickness on the outside of this tool is less than Sansi, but there are a total of 700 layers, and we can only get up to 120 layers..." Yun Fei sighed.

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

Just like their 32-bit chips, it was obvious that he had just arrived in Rongcheng, and soon after he had Soviet technical experts in his hands, he quickly produced them. At that time, European and American countries mainly used [-]-bit chips.Researching sixteen-bit chip technology, he did not dare to sell this chip technology to the world on a large scale. Even in China, he only used it for himself and provided it to the military for some research.

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

Not to mention that he imposed a technological blockade on the entire world out of patriotism.

But foreign technology is far more advanced than China.Once they understand the principles, rely on their years of accumulated technical experience.It is completely possible to succeed in a very short test, and then the slight technological lead that Yunfei had with great difficulty will be gone.

Even after the 16-bit chip has been introduced to the market in the past two years, it has not replaced the 32-bit chip technology, mainly because the cost is too high.And the technical advantages are not too prominent.Up to now, 16-bit chips have begun to appear on the market, although the cost is ridiculously high now.But this replaces [-]-bit chips and eight-bit chips, and it will not exceed two years at most.

That's the basics.

"Wouldn't it be possible to achieve this level of wear resistance by making it thicker?" As for technology, Zhang Hu is so amateurish that he can no longer be an amateur.

Hearing what he said, Deng Lanqing immediately rolled her eyes and left. She was not ashamed to be with such a guy who pretended to understand and asked questions that were beyond layman.

Yun Fei immediately looked at Zhang Hu and smiled wryly: "I said, Uncle Zhang, can you ask some more expert questions? Didn't you see that Mr. Deng didn't even bother to stand with you? This question is really idiot Incomparable. If it were really that easy, would we be short of knives?"

Zhang Hu suddenly became astonished.

He, who is not a professional, can't understand the doorway here.Immediately, he looked at Yun Fei suspiciously, hoping to get an answer.

"The thicker the coating, the better the coated tool. The coating on the outside is just to increase the wear resistance of the tool during the cutting process, especially the cutting edge. This is the position..." Yunfei held the alloy milling cutter in his hand He picked it up, pointed to the blade and introduced it to Zhang Hu.

Zhang Hu nodded: "I know this. Milling cutters mainly rely on this side edge for cutting. Don't pretend 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 immediately speechless.

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

Who said that the main cutting of the milling cutter is to rely on the two side edges?Do you know that there are still many special milling cutters that rely on the cutting edge at the bottom for cutting?But Yunfei is too lazy to explain to Zhang Hu now, it is very difficult to explain these professional technical knowledge to people who do not understand technology.

"These massacre materials mainly use vapor deposition method or physical deposition method, or use the two methods alternately to apply the ionic state coating to the substrate of the tool... Don't ask what physical deposition method or vapor deposition method is. You need to know that these are two different types, and you can just stick these very fine wear-resistant materials to the base of the tool..." Seeing Zhang Hu's puzzled face, Yun Fei was about to speak, but was suddenly a little speechless.

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

Zhang Hu nodded, even though he was in a fog, he still didn't interrupt Yun Fei's words.

When he arrived at the Jiuyi Research Institute, those guys didn't explain this to him. Perhaps they were afraid that the explanation would be too laborious, so they didn't mention these professional terms at all.

"The thicker the coating, the better, because these wear-resistant materials have very high hardness and are very brittle, just like those ceramics, are they hard enough? But they are easy to break. What's more, these coatings If the material is too thick, the cutting edge of the tool will become blunt. For difficult-to-machine materials with good cutting toughness, it is necessary to ensure the sharpness of the blade..." Yun Fei explained to Zhang Hu for a long time, and Zhang Hu finally understood it paradoxically Why isn't the thicker the better the coating.

"So, 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. In terms of level, Yun Fei was just about to nod his head, let out a sigh of relief and lamented his difficulty, Zhang Hu said something that made him go berserk: "Oh, why don't you tell me this earlier? You have to show off your professional knowledge in front of me, wrap me in a cloud and tell me that the thinner the coating, the better, the more the better..."

"I can't have a pleasant communication with you..." Yun Fei was speechless for a moment.

"So, if Jiuyi Materials develops such a knife, it can be sold for four hundred dollars? Boy, this is a sign that you are going to get rich!"

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

Especially in Japan and the United States, the technology in this area is definitely not bragging, and the Chinese can't help but admire it.

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

"If we have such technology in our country, or if Europe and the United States don't block us, do you think we use some shady methods to obtain these knives? Go back after seeing for yourself. The food in our cafeteria is not as good as your government canteen. It's far away..." It seems that Deng Lanqing's departure is not unreasonable.

It is too much effort to communicate with these non-technical people.

"Now I know why I should avoid him? Our domestic foundation is poor, and our research institute and these supporting factories can't accomplish it at all. He has to explain to him every time he comes, which makes people's brains big." Seeing Yunfei walking towards him as if he was going to eat people, and Zhang Hu walking towards this side behind Yunfei, Deng Lanqing immediately looked at Yunfei with a sympathetic look.

"Let's just ignore him. He does whatever he likes. I don't know what the big bosses above think. Why did he get him, a guy who doesn't know much about technology, to be the person in charge of industry and let him be in charge of the economy? Okay..."
