"Xiao Yun, you have a franchise. Even if the patent is not in your hand, there is nothing to worry about. Are you still worried that the state will pit you?" Situ Heyun is a little strange. Why does Yunfei want both franchise and patent.

    "I''m not worried that the country will pit me, but I''m worried that some people who can represent the country will pit me!" Looking at Sun Lin, Yun Fei was very nervous, but in order that his efforts would not be made like cabbage all over the street by those self righteous people in the future, he could not give in at this time.

    In China, many people don''t care about business rules. In order to win over customers, we can say that we will do anything by any means. The worst is the price war! Especially those resource-based things exported by China, such as rare earth and wood products, once became the price of Chinese cabbage in the middle and late 1990s, which made foreign agents laugh.

    Seeing that there are profits, countless people rush into mass action and the production level is uneven, which not only destroys the whole market, but also brings down the whole industry because of the price war of those weak manufacturers.

    The devil''s country once imported a large amount of wood in China because of its narrow land area and lack of resources, especially wood with large consumption. Before the 21st century, most of the goods exported by China were resource-based exports. Fortunately, later, China''s economic construction achieved certain results. When countless people found that there were few resources left to future generations, they began to call on the government to limit these predatory exploitation of resources for export.

    Rare earth is the most obvious example. The use of rare earth is mainly in the military industry, especially in the precision guidance of missiles. There are few such resources in Japan. Since the 1980s, Japan has imported rare earths from China, not only for its own research, but also for massive hoarding. For the sake of political achievements, Chinese local governments have never thought that their children and grandchildren will not use these things after the exploitation of non renewable resources such as rare earths.

    After all, the Tartars began to publicize that China has a vast territory and abundant resources, especially after uncle Mao led the whole China to overthrow the three mountains on the Chinese people and establish a socialist new China.

    9.6 million square kilometers of territory, nothing? Worried about rare earth being mined out? Jokes. How can such a big China have only such a little resources? In exchange for the country''s scarce foreign exchange, in addition to nuclear raw materials, which are also scarce in China, what resources can not be exported?

    Therefore, the devil who is extremely short of rare earth resources has come; The United States, which is extremely rich in rare earth resources, has also sealed up domestic mines. After all, the cost of mining rare earth mines in the United States is even higher than that imported from China!

    In order to achieve political achievements and boost GDP, in Inner Mongolia, where rare earth resources are densely distributed, in order to compete for more markets and exchange more foreign exchange, local governments continue to reduce prices under the provocation of devils and the United States.

    Rare earth purchasers often say to private miners who exploit wantonly against the background: "you see, other people''s prices are lower than you. No matter how good our relationship is, if I spend a high price on your rare earth, I will be destroyed by the lower cost of my peers..." private miners will definitely pat their chest and say, "who and who are we? Our mining costs are the same. He dares to reduce the price. Why don''t I dare to reduce it? I''m cheaper than others! "

    Anyway, in addition to the investment of mining equipment, labor needs wages, and some filial expenses, the rest are their own. Private rare earth miners often say, don''t fucking mention the country to me. Some people in my family have devoted their lives to the country, so I shouldn''t dig any mines in the country? Lying on the ground is a waste. It''s better to exchange the scarce foreign exchange of some countries. Lao Tzu is making contributions to the country!

    The devil smiled

    The United States also smiled

    China''s disposable chopsticks exported to Japan also face such problems because of the low production threshold. In the end, the sales price can not even catch up with the production cost. Countless small factories producing disposable chopsticks closed down for this reason.

    "This..." situ Heyun also couldn''t answer Yunfei''s words. They have also heard about the current situation in China.

    "Xiao Yun, let''s put this matter aside first. Can you tell us more about your project?" Seeing that Yunfei didn''t give in at all, Sun Lin knew that he had to give up. They can''t do this at all. They must go back and study it and get the approval of the superior department before they can reply to Yun Fei.

    "There''s nothing to say. I''ve said it several times..." Yun Fei was a little impatient. 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, don''t we?

    If everyone is like you, without a clear intention of cooperation and the foundation of cooperation has not been established, it would be unkind to inquire about these trade secrets, wouldn''t it?

    "Ha ha..." Sun Lin heard Yun Fei''s impatient answer and smiled awkwardly.

    "Xiao Yun, for the development of foreign CNC machine tool technology, you have stayed in the Pearl River Delta for so long. I heard from Xiao Ren that you have been collecting CNC machine tools everywhere. I think you still have a lot of knowledge about these foreign machine tools?" Seeing that the conversation was about to reach an impasse, situ Heyun quickly changed the topic.

    Zhao Xingbang was beaten in the face by Yun Fei at first, but he didn''t dare to collide in front of situ Heyun and sun Lin. These two old guys represent the rear decoration headquarters and the Commission of science, technology and industry for national defense. He is just the director of the rear decoration procurement department of a small military region. If they offend these two old guys, although they can''t repair themselves, the identity of the person they contact is higher than themselves. As long as they casually say that one of them is not, there will be no future prospects. He is only in his fifties, and there is only one Venus hanging on his shoulder. He still wants to add another star to his shoulder.

    Zhao Xingbang also knows that his requirements are a little too much. After all, camart threatened to forcibly occupy more than half of the NC workshop capacity of the original Qingfeng machinery because of his relationship and pressure. Who is Yunfei defending now? Two old guys don''t know. How can he not understand?

    Ren Zhiguo and Ma Ji basically play soy sauce. Not only can they not wander, they also have to sit straight and listen to the chat of several others. Maggie is fine. After all, he''s used to it. However, Ren Zhiguo is a little uncomfortable. He wants to leave, but he can''t. Now there is always an end to the depressing problem. How can we not breathe?

    "I personally don''t know much about foreign CNC technology. However, from the machine tools I got, although many are machine tools from the 1980s, we can also see some trends. Now foreign CNC machine tools are mainly thinking about the development of flexible manufacturing, which has changed the previous compound production mode, and the machine tools are gradually moving towards specialization. This is also the reason why there are countless types of four-axis linkage, five axis linkage and even more high-end machine tools. These multi axis linkage machine tools are not only to produce some high-precision parts. It''s mainly to concentrate the production processes of the same type of products... "Yun Fei''s statement made several people nod.

    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 gradually developing towards high speed, high precision and high moving speed. For example, the numerical control machine tools for woodworking in Germany, which are used to process some easily processed materials such as wood, hard aluminum alloy and aviation aluminum, can even reach 30000 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 cutting tools and machine tool accessories... "Yun Fei said here, showing infinite longing in his eyes.

    "Xiao Yun, how is it possible to rotate at 30000 RPM? A tool handle plus a tool can weigh one kilogram. How much torque does this rotation produce? Won''t the knife fall? " Sun Lin should be regarded as an authoritative expert in China''s machinery manufacturing field. When he heard Yun Fei say so, he didn''t think of it at all. At 30000 revolutions per minute, the running speed of the machine tool will have to be 500 revolutions per second! This is beyond his imagination.

    Speaking of this, we have to talk about hydraulic and pneumatic, and we have to talk about materials, but can Yunfei tell them? Did you tell Sun Lin that you were out? In my world, at that time, the maximum spindle speed of the machine tool had reached 80000 RPM? In fact, for those materials, Yunfei is not very clear.

    Yunfei''s original factory used tools for processing tungsten molybdenum alloy. All the tools produced by domestic materials have been tried, but they can''t cut efficiently. Finally, through the relationship, we got some ultra-fine powder metallurgy alloy tools from the devil, and the efficiency is five or six times higher than the best ys8 alloy tools in China! Compared with that kind of devil''s knife, ys8 is not wear-resistant at all. Not only the rotating speed is lower, the cutting speed is slower, but also it is not wear-resistant. For tungsten products with 300 large diameters, when the ys8 tool is turned to 200 lengths, the tool tip is worn out by more than one 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 working for several months, but they have not completely analyzed the components in the devil''s knife!

    "This design involves many aspects, such as materials, cutting tools, hydraulic pressure and start-up, engineering mechanics, etc. I just heard, and I don''t know what''s going on." Yun Fei made a helpless expression to sun Lin.

    Hearing Yunfei say this, Ren Zhiguo was surprised. He didn''t see Yunfei communicate with anyone. Where did he know the information?

    "In fact, these are not the development direction of CNC machine tools. With the rise of computer industry and the development of functions, the main development direction of CNC machine tools is intelligent industrial robots!" Finally, Yun Fei''s words shocked two national engineers!

    They haven''t even found the way to the lowest CNC machine tools. They are actually engaged in intelligent industrial robots abroad! Although I don''t know the evidence of Yun Fei''s statement, it''s definitely not nonsense.

    With the passage of time, foreign CNC machine tools have become more and more advanced and powerful. Three axis machining center, with automatic tool change mechanism and manipulator for loading and unloading workpieces, has been regarded as the simplest industrial robot.
