Chapter 895

Therefore, no matter from which aspect, the export of CNC machine tools of Jiuyi heavy industry is imperative. If you are shrinking in China, those big men have a reason to suppress them.

But all this is based on the research of high-end machine tools with five axes and five linkage.

Internationally, the market of four-axis machine tools is not as large as that of five axes. Many parts requiring four-axis processing have low precision requirements and processing cost requirements. They are often processed by simple four-axis machine tools equipped with PMC controlled rotary worktables; For parts or products with high precision requirements, there are basically no great requirements for cost. All these are five axis CNC machine tools with stronger processing capacity.

The four axes abroad are basically a transitional model.

However, compared with the five axis linkage four axis three linkage CNC machine tool, it is really very cheap. However, if you export to the Chinese market, you can sell at a high price. Who says that China has huge demand and can't produce it by itself?

If it were not for the emergence of Yunfei, China had made a simple fourth axis since the early 1990s, which made foreign CNC manufacturers lose at least hundreds of millions of dollars in profits. When China was able to produce this simple four-axis machine tool, China imported at least hundreds of sets from abroad! And this price, from the beginning of millions of dollars, has basically not decreased much.

Even for those produced in Taiwan, the price is not something that ordinary people can look up to.

China's numerous state-owned enterprises are the biggest buyers. Therefore, the Chinese government is the most injured person. A lot of foreign exchange is earned by Taiwan and foreign CNC manufacturers.

No? If you don't buy, you don't have the right.

Anyway, where is the Wassenaar agreement? Does China want more advanced machine tools? Dream.

Moreover, these equipment must be used for the processing of various mechanical products and high-precision complex parts, unless China has a large number of scientific researchers comparable to the former Soviet Union, and everything is a special machine for design.

After Yunfei came to this world, the first thing is to install the fourth axis driven by PMC module in the three-axis NC machining center to form a simple four-axis function of four-axis three linkage, which leads to Zhao Xingbang, who was absolutely a big man for Yunfei at that time.

With more than 10 million funds, we can move 9327 factory to Chengdu and start with a loan of 30 million. These are the existence of this simple four-axis technology. Strictly speaking, the cloud does not start, but actually starts with this project. Without the support of the military, it was impossible for him to contract 9327 belonging to the strategic factory, and when someone bothered him, the military boss Li Zhongwei directly said that the whole military was the backer of cloud and Africa.

This shows the importance of this technology to China.

Now, China has five axes, but foreign countries are not allowed to export such top strategic equipment to China due to the provisions of the wassena agreement, which makes the five axes of Jiuyi heavy industry have a very huge market. Moreover, the 91 Research Institute has always attached great importance to confidentiality in this regard.

Not long after the four axis machining center was just taken out, foreign machine tool factories simply did not expect that they could have relatively high-precision five axis machining center technology so soon!

"When we enter the international market, all the pressure will appear on us. No one in the world would want China to rise, especially the United States and Japan... "Deng Lanqing said solemnly.

"As long as we master the five axis technology and are released, even if we do not enter the international market, these pressures will also appear. Under the same pressure, why don't we occupy more markets? " Yun Fei smiled.

Five axis is too important for the aerospace industry.

Their large aircraft projects, the J-10 and j-20 of 132 and the J-11 of Shenyang airlines, require five axis CNC machine tools to reduce costs and improve production efficiency. Otherwise, large-scale manufacturing is impossible.

"How is the current control system?" Yunfei changed the topic. These things have nothing to do with researchers, and the market has nothing to do with R & D personnel. The R & D personnel he asked for are only responsible for technology R & D, and don't care about anything else.

Otherwise, if researchers waste a lot of energy on irrelevant things, how can they develop technology?

"The problem of the system is not bad, mainly because the measurement technology studied by the Institute of Optoelectronics has not made breakthrough progress, and the service life of the spindle is not long enough..." these problems can not be solved in a short time.

"Isn't there no problem with the spindle?" Yun Fei frowned.

Their spindle technology, but the most advanced in China, is the technology he copied from Japanese Mazak and Mitsubishi. All kinds of materials, formulas and processes have been developed by many factories.

"That's an ordinary spindle. Our research on motorized spindle technology has not been successful. Moreover, ordinary spindles are used on five axes, because they need to rotate in the direction of a axis and C axis. Those spindles with excessive load can't be used on them. The newly developed spindles will deform as soon as the heavy load cutting test is carried out because the wall is too thin... "When it comes to this, Sun Lin has a big head.

The spindle system is the key component of a CNC machine tool.

Especially finishing equipment.

"The five axis spindle is still undergoing heavy load cutting test?" Yun Fei was immediately depressed.

Isn't it unnecessary to take off your pants and fart?

Five axis machining center is such an expensive equipment, which rich and rough company will be willing to use a five axis machining center worth tens of millions to roughen the blank?

"Yes, didn't you say that all our machine tools must be subject to heavy load cutting test? The spindle is the most critical component. In recent years, dozens of experiments have been carried out. No matter how we modify the production process and design scheme, we can't make much progress... "Sun Lin sighed.

Yun Fei immediately wanted to slap himself.

He felt that if he listened to Sun Lin go on, he would strangle himself, because none of the many domestic CNC machine tool manufacturers had done heavy-duty cutting tests, and only the top machine tool manufacturers such as Germany Dirk would do such tests abroad.

Because it is not necessary at all, CNC machine tools rarely process blanks.

Therefore, Yun Fei stopped Sun Lin from going on: "Mr. Sun, the five axis machining center originally belongs to precision machining equipment. There are tens of millions of things. Who would be willing to use such equipment for rough machining?"

"Er..." Yun Fei's words immediately made Sun Lin's old face red.

Before contacting Yunfei, they were still studying two axis CNC lathes and three axis two linkage CNC milling machines

Sun Lin did not expect to make such great progress so soon.

Yun Fei did say at the beginning that all equipment must be subject to heavy load cutting test. They formed an inertial thinking. Four axes have been done, and five axes still have to sit. Due to the price problem and machining accuracy requirements of the four axes, it is very normal for the rough machining and finishing machining to be combined, but not for the five axes.

Five axis, because of the higher precision and the cheap three-axis, can be used for approximate contour cutting for rough machining. Most of the allowance that needs to be cut is removed, and then directly go to the five axis for finish machining.

Sun Lin and his colleagues have always gone into a misunderstanding, that is, in order to pursue high efficiency, the machining centers are all rough and fine machining together, especially now many production are single piece and small batch production mode, and mass production is often the way of assembly line production in top manufacturing.

High grade CNC machine tools are often used in cutting-edge manufacturing industries such as molds, aerospace and medical devices, which are not too large. The mass production of parts using CNC equipment is assembly line processing, that is, the pursuit of standardization and high production efficiency.

"You mean these five axes don't have to be subjected to heavy load machining test at all? Moreover, our tens of millions of funds in this regard are wasted? " Sun Lin asked with a red face.

How can this not be wasted?

Yunfei immediately felt his heart dripping blood, which was tens of millions of research funds.

However, he can't say anything, because this is mainly the responsibility of his boss. Many research directions in the research institute are designated by his boss. If you tell Sun Lin that tens of millions of dollars have been wasted, the old man will certainly resent and blame himself.

"In fact, it can't be said to be a waste. When there were no competitors in the early stage, even if the service life of these spindles was only one year, the market users would not say anything, but in the later stage, when a large number of foreign five axes were exported to our country, this would not be the case. If the bearing capacity of the spindle is stronger, other people's machining centers can only eat 0 and 05 with a knife, while ours can reach 0, 1 or even 0 and 2. This efficiency comparison is the most obvious... "Yun Fei is depressed, but he says with a smile on his face.

The processing cost of the five axis machining center is five or six hundred an hour. The higher the efficiency, the lower the cost. In this era of higher and higher cost, this is also a big selling point. This is a windfall.

The precision of the spindle made by the 91 Research Institute may not be comparable with that of foreign countries, but it will definitely exceed that of foreign spindles in terms of service life and leather. You know, the production cost of a spindle of a five axis machining center is hundreds of thousands, and the selling price is at least millions!

"What's more, the stronger the overload capacity of our spindles, the machining accuracy can be guaranteed, which is a good thing for our brand!"

"Alas!" How can Sun Lin not know that Yunfei is comforting him?

"Even if we don't do it now, we will do research in this field later. Only when we have a five axis machining center in our hands and can form a complete series with our three-axis machining center and other equipment of different grades, can we ensure sufficient market competitiveness. " Yun Fei saw a lonely expression on Sun Lin's face and couldn't help saying so.
