Therefore, no matter from which aspect, the export of CNC machine tools of Jiuyi Heavy Industry is imperative. If they are cowering in China, those bigwigs will have a reason to suppress them.

However, this qiē is based on the research of high-end machine tools with five axes and five linkages.

Internationally, the market of four-axis machine tools is not as huge as the five-axis, and many parts that need four-axis machining are not high, and the processing cost is required. The parts or products with high precision requirements basically do not have much requirement for cost, and these are all CNC machine tools with stronger processing capacity and five-axis linkage.

The foreign four-axis is basically a transitional model.

However, this kind of four-axis three-linkage CNC machine tool is indeed very cheap compared to the five-axis linkage of the four-axis three-linkage CNC machine. However, if you export to the Chinese market, you can sell it for a large price, who says that China has an incomparably huge demand, and it can't produce it itself?

If it weren't for the emergence of Yunfei, China from the early nineties to make a simple fourth axis, so that foreign CNC manufacturers lost at least hundreds of millions of dollars in profits, in China can produce this simple four-axis machine tool, China imported at least hundreds of units from abroad! And this price, from the beginning of millions of dollars, basically did not fall much.

Even the price produced by the Taiwan factory is not a store that ordinary people can look up to.

China's many state-owned enterprises are the biggest buyers. Therefore, the Chinese government is the most injured person, and a lot of the small amount of foreign exchange has been earned by Taiwan and foreign CNC manufacturers.

Don't buy? If you don't buy it, you don't have the right.

Anyway, where is the Wasena Agreement, China wants more advanced machine tools? Dream on.

Moreover, all kinds of mechanical products, high-precision complex parts processing, these equipment are necessary, unless China has a huge number of scientific researchers comparable to the former Soviet Union, and the production of everything is a design machine.

After coming to this world from Yunfei. First of all, the three-axis CNC machining center is equipped with a PMC module, and the fourth axis driven by the PMC module forms a simple four-axis function with three linkages, which leads to Zhao Xingbang, who was definitely a big man for Yunfei at that time.

With more than 10 million funds, the 9327 factory was relocated to Rongcheng, and then the loan of 30 million yuan was used to start the business, which is the saving of this simple four-axis technology. Strictly speaking, Yunfei started with this project. Without the support of the military, it would be impossible for him to contract the 9327 belonging to the strategic factory, and when someone was asking him for trouble, the military boss Li Zhongwei directly said that their entire military was Yun Fei's backer.

This shows the importance of this technology to China.

And now, China already has five axes. However, due to the provisions of the Wasena Agreement, foreign countries are not allowed to export such top-level strategic equipment to China, which makes the five axes of Jiuyi Heavy Industry have a very large market. Moreover, the 91 Research Institute has always attached great importance to the secrecy of this aspect.

Not long after the four-axis machining center was brought out, foreign machine tool factories could not imagine that they could have a relatively high-precision five-axis machining center technology so quickly!

"When we enter the international market, all the pressure will come to us. In this world, no one would want China to rise, especially the United States and Japan,......" Deng Lanqing said with a stern face.

"As long as we have mastered the five-axis technology and it is announced, even if we do not enter the international market, these pressures will also appear. Same pressure. Why don't we occupy more markets? Yun Fei smiled.

The five axes are too important for the space industry.

Their large aircraft projects, 132's J-10, J-20, and Shen Fei's J-11. Many of these parts need to be machined by five-axis CNC machines to reduce costs and improve production efficiency, otherwise, mass manufacturing is simply impossible.

"What is the current control system?" Yun Fei has changed the topic, and these things have nothing to do with researchers. The market has nothing to do with R&D personnel. The R&D personnel he asked were only responsible for technology research and development, and nothing else was left to chance.

Otherwise, researchers waste a lot of energy on unrelated things, how can they come up with technology?

"The problem with the system is not bad. The main reason is that there has been no breakthrough in the measurement technology researched by the Institute of Optoelectronics, and at the same time, the service life of the spindle is not long enough...... "These problems cannot be solved in a short time."

"Isn't there no problem with the spindle?" Yun Fei couldn't help frowning.

Their spindle technology, but the most advanced in the whole of China, is still the technology he copied from Japan's Mazak and Mitsubishi. All kinds of material formulas and processes are made by integrating many factories.

"It was an ordinary spindle, and our electric spindle technology has been studied without success. Moreover, the ordinary spindle is used on the five axes because it needs to rotate in the direction of the A axis and the C axis, and those overloaded spindles cannot be used on it, and the newly developed spindle is too thin ...... the wall will produce deformation as soon as the heavy load cutting test is carried out.

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

Especially the finishing equipment.

"The five-axis spindle is still undergoing heavy-duty cutting tests?" Yun Fei was immediately depressed.

Isn't this taking off your pants and farting, and that's an extra move?

With such an expensive equipment as a five-axis machining center, which company with deep pockets would be willing to use a five-axis machining center worth tens of millions to rough the blank?

"That's right, didn't you say that all of our machine tools must be cut with heavy loads? The spindle is the most critical component. In the past few years, we have carried out dozens of experiments, and no matter how we modify the production process and modify the design plan, we can't make much progress......," Sun Lin said with a sigh.

Yun Fei suddenly wanted to give himself a few slaps.

He felt that if he listened to Sun Lin continue, he would strangle himself, because none of the many CNC machine tool manufacturers in China had done heavy-load cutting tests, and only the top machine tool factories such as German Dirk would do such tests abroad.

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

Therefore, Yun Fei stopped Sun Lin from continuing: "Sun Lao, the five-axis machining center originally belonged to precision machining equipment, tens of millions of things, who would be willing to use such equipment for rough machining?" ”

"Uh......" Yun Fei's words suddenly made Sun Lin's old face red.

Before contacting Yunfei, they were still working on two-axis CNC lathes and three-axis and two-linkage CNC milling machines......

Sun Lin had no idea that he would make such great progress so quickly.

And Yun Fei did say at the beginning that all equipment must do heavy load cutting tests, and they formed an inertial thinking, four axes have been done, and five axes still have to sit. Because of the price problem and machining accuracy requirements of the four axes, it is very normal for rough machining and finishing to be combined, but the five axes are not good.

Five-axis, because of the higher accuracy, plus the cheap three-axis can be used to make approximate contour cutting for rough machining, most of the allowance that needs to be cut is dried up, and then directly on the five-axis for finishing.

Sun Lin They have always entered a misunderstanding, that is, in order to pursue high efficiency, the machining center is rough and fine processing together, especially now that a lot of production is a single piece of small batch production mode, mass production in the top manufacturing is often the way of assembly line production.

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

"You mean that these 5-axes don't need to be tested for heavy-duty machining at all? Moreover, our tens of millions of dollars in this area are wasted? Sun Lin asked with a red face.

How is this not wasted?

Yun Fei suddenly felt that his heart was dripping blood, this is tens of millions of research funds.

However, he had no way to say anything, because this was mainly the responsibility of his boss, and many research directions in the research institute were designated by his boss. If it is a waste of tens of millions to sue Sun Lin, this old guy will definitely be angry and blame himself.

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

The processing cost of the five-axis machining center is five or six hundred per hour, and the higher the efficiency, the lower the cost, which is also a major selling point in this era of higher and higher costs. That's a windfall.

The accuracy of the spindle made by the Jiuyi Research Institute may not be comparable with that of foreign countries, but it will definitely exceed the foreign spindle in terms of service life and leather. You must know that the production cost of the 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 main bearings, the more accurate the machining accuracy can be guaranteed, which is a good thing for our brand!"

"Alas!" How could Sun Lin not know that Yun Fei was comforting him?

"Even if we don't do it now, we will do research in this area in the future. Only when we have a five-axis machining center in our hands, can form a complete series with our three-axis machining center and other equipment of different grades, so as to ensure sufficient market competitiveness. Yun Fei saw a lonely expression on Sun Lin's face, and couldn't help but say so. (To be continued......)
