"Xiaoyun, you have a franchise, even if the patent is not in your hands, there is nothing to worry about, are you still worried that the country will cheat you?" Situ Heyun is a little strange, Yun Fei wants to have a franchise, but also bite the patent right and not let go.

"I'm not worried about the state cheating on me, but I'm worried about some people who can represent the country cheating on me!" Looking at Sun Lin, Yun Fei was extremely nervous, but in order to prevent his hard work from being turned into cabbage on the street by those self-righteous people in the future, he couldn't give in at this time.

In China, many people do not care about business rules, and they can do whatever it takes to win over customers. The worst thing is the price war! In particular, the resource things exported by China, such as rare earths and wood products, once became the price of Chinese cabbage in the mid-to-late nineties, which made those foreign agents smile.

Seeing what has profits, countless people rush to the top, and the production level is uneven, which not only messes up the entire market, but also drags down the entire industry because of the price war of those manufacturers who are not strong.

Because of its narrow land area and lack of resources, especially the resources of timber that consumes a lot of money, the country of devils once imported a large amount of resources in China. Before the 21st century, most of the goods exported by China were resource exports. Fortunately, China's economic construction has achieved certain results, and countless people have begun to call on the government to limit these predatory exploitation of resources for export when countless people found that we did not have many resources left to future generations.

Rare earths are the most obvious example. The use of rare earths is mainly in the military industry, especially in the precision guidance of missiles. Japan has very few of these resources in Japan, and since the 80s, it has been importing rare earths from China, not only for its own research, but also for large quantities. For the sake of political performance, China's local governments have never thought that after the mining of rare earths, non-renewable resources, children will not be able to use these things.

After all, propaganda began in the Great Qing Empire from the Tartars. China is rich in land and resources, especially after Uncle Mao led the whole of China to overthrow the three mountains that pressed on the Chinese and establish a socialist New China, the Chinese are even more proud.

Nine and six thousand square kilometers of territory, what is not? Worried about rare earths being mined? Joke. How can a huge China have only such a small amount of resources? In exchange for the country's scarce foreign exchange, apart from nuclear raw materials, which are also in short supply in China, what other resources cannot be exported?

Therefore, the devil who is extremely lacking in rare earth resources is coming; The country, which is incomparably rich in rare earth resources, has also sealed the domestic mines. After all, the cost of mining rare earth minerals in the United States is even higher than importing them from China!

In order to achieve political performance and increase GDP, local governments continue to reduce prices in places such as Inner Mongolia, where rare earth resources are densely distributed, in order to compete for more markets and exchange for more foreign exchange.

Rare earth buyers often say to private miners who are mining from the background, "Look. Other people's prices are lower than yours, no matter how good our relationship is, I spend a high price to buy your rare earths, and I will be collapsed by the lower cost of my peers......" Private miners will definitely pat their chests and say: "Who are we with whom?" Our mining costs are all the same. He dares to lower the price, why doesn't Lao Tzu dare to lower? Lao Tzu's price is lower than others! ”

Anyway, these things, in addition to the equipment for mining need to be invested, and the labor needs to be paid. By the way, add some filial piety expenses, and the rest is your own. Private rare earth mine owners often say, don't mention the country to Lao Tzu. There are people in Lao Tzu's family who have dedicated their lives to the country, so should Lao Tzu dig a little mine in the country? Lying on the ground is a waste, and it is better to exchange for foreign exchange that is in short supply in some countries. Lao Tzu, this is to contribute to the country!

The devil laughed......

Mi Guo also smiled......

China's disposable chopsticks exported to Japan, because of the low production threshold, also face such a problem, to the bottom of the line, the sales price can not even catch up with the production cost. Countless small factories that produce disposable chopsticks have closed down for this reason.

"This ......" Situ Heyun was also unable to answer Yun Fei's words. The current situation in China, these people who are engaged in research have also heard of it.

"Xiaoyun, let's put this matter aside for a while, can you tell us more about your project?" Seeing that Yun Fei had no intention of backing down, Sun Lin also knew that he could only give up. They can't do this at all, they have to go back to study it and get the approval of the higher authorities before they can reply to Yun Fei.

"There's nothing to say about this, what can be said, what should be said, I've already said it several times......" Yun Fei was a little impatient. In this matter, no matter how high your status is, how can you represent the country, since we want to talk about cooperation, we have to follow the business rules, right?

If all people are like you, there is no clear intention to cooperate, and the foundation of cooperation has not been established, it is too unkind to inquire about these trade secrets, right?

"Hehe......" Sun Lin smiled awkwardly when he heard Yun Fei's impatient answer.

"Xiaoyun, for the development of foreign CNC machine tool technology, you have been in the Pearl River Delta for so long, I heard Xiao Ren say that you have been collecting CNC machine tools everywhere, presumably there is still a lot of understanding of these foreign machine tools, right?" Situ Heyun saw that the conversation was about to reach an impasse, and hurriedly changed the topic.

Zhao Xingbang was slapped in the face by Yun Fei at first, but he didn't dare to have the slightest confrontation in front of Situ Heyun and Sun Lin. These two old guys represent the rear assembly headquarters and the Commission of Science, Technology and Industry for National Defense, and he is just the director of the rear assembly procurement department of a small military region. If they offend these two old guys, although they can't fix themselves, the people they come into contact with are higher than themselves, as long as they casually say that he is not, there will be no prospects for the future. He was only in his fifties now, and he only had a gold star on his shoulder, and he wanted to add another star to his shoulder.

Zhao Xingbang also knew that his request was a bit excessive. After all, at the beginning, because of his relationship and pressure, Kamat threatened to forcibly occupy more than half of the original Qingfeng Machinery's CNC workshop capacity. Who is Yun Fei's defense now, the two old guys don't know, how can he not understand?

Ren Zhiguo and Ma Ji are basically soy saucers, not only can't desert, but they also have to sit straight and listen to the other people chatting. Ma Ji is fine, after all, he is used to it. However, Ren Zhiguo was a little uncomfortable, he wanted to leave, but he couldn't. Now there is an end to that depressing problem. How can you not breathe a sigh of relief?

"I don't know much about foreign CNC technology. However, from the machines I have obtained, although many of them are from the 80s, I can also see some trends. At present, foreign CNC machine tools are mainly developing in the direction of flexible manufacturing, changing the previous composite production mode, and machine tools are gradually becoming specialized. This is also the reason why four-axis linkage, five-axis linkage and even more high-end machine tools have countless types of divisions. These multi-axis machines are not just for the production of high-precision parts. It's mainly to centralize the production process of the same type of product......" Yun Fei's statement made several people nod their heads when they heard it.

However, they have heard of four-axis and five-axis CNC machine tools and have always wanted to get them.

"Another development direction of modern CNC machine tools is to gradually start to move towards high speeds. High precision, high moving speed in the direction of development. For example, the German woodworking CNC machine tools, which are used to process some easy-to-process materials such as wood, duralumin alloy, and aviation aluminum, can now even reach 30,000 revolutions per minute, and the moving speed can reach hundreds of meters per minute. At the same time, the machining accuracy can reach within 0.001mm, however, these machine tools have very high requirements for tools and machine tool accessories......" Yun Fei said this, his eyes showed infinite yearning.

"Xiaoyun, 30,000 rpm. How can it be? A tool holder plus a knife weighs a kilogram, how much torque does this rotation generate? Won't the knives fall off? "Sun Lin should be regarded as a relatively authoritative expert in the field of machinery manufacturing in China, hearing Yun Fei say so. Didn't think of it at all. 30,000 revolutions per minute, the running speed of the machine tool has to be 500 revolutions in one second! This was something he couldn't even imagine.

Speaking of this, we have to talk about hydraulics and pneumatics, and we have to talk about materials. But can Yun Fei tell them? DO YOU WANT TO TELL SUN LIN, YOU ARE OUT, IN MY WORLD. At that time, the spindle speed of machine tools had reached a maximum of 80,000 revolutions per minute? Actually, Yun Fei is not very clear about those materials.

Yunfei's original factory processed tungsten and molybdenum alloy tools, all domestic material production tools have been tried, but they are unable to carry out high-efficiency cutting. After the relationship, some ultra-fine powder metallurgy alloy tools were obtained from the devil, and the efficiency was five or six times higher than the best YS8 alloy tools in China! Compared to that kind of devil's knife, the YS8 is not wear-resistant at all. Not only is the rotational speed lower, the cutting speed is slower, but it is also less wear-resistant. For 300 large-diameter tungsten products, the YS8 tool is turned to a length of 200, and the tip of the knife is worn out by more than a millimeter, while the devil knife is only worn out by less than 0.1mm! The physical and chemical analysis room of their factory has been engaged in it for several months, but they have not completely analyzed the ingredients in the devil knives!

"There are many aspects of this design, materials, tools, hydraulics and starting, engineering mechanics, etc., I have only heard about it, and I don't know what exactly is going on." Yun Fei made a helpless expression at Sun Lin.

Hearing Yun Fei say this, Ren Zhiguo was surprised, he didn't see Yun Fei communicate with anyone about this, where did he know this information about Lu Dao?

"In fact, these are not the development direction of CNC machine tools, with the rise of the computer industry and the development of functions, the main development direction of CNC machine tools is intelligent industrial robots!" After talking about the most, Yun Fei's words shocked the two national-level engineers!

They haven't even touched the way of the lowest-level CNC machine tools, and foreign countries are already engaged in intelligent industrial robots! Although I don't know what evidence there is for Lu Daoyunfei's statement, but if you think about it carefully, it is definitely not nonsense.

With the passage of time, foreign CNC machine tools have become more and more advanced and more powerful. The three-axis machining center, with an automatic tool change mechanism and a manipulator for loading and unloading workpieces, can be regarded as the simplest industrial robot.
