Intelligent Industrial Empire

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

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

Internationally, the market for four-axis machine tools is not as large as five-axis. Many parts that require four-axis machining have low precision and processing costs. They often use a rotary table with PMC control to form the fourth axis. The simple four-axis machine tool processing; and the parts or products with high precision requirements basically do not require much cost. These are all five-axis CNC machine tools with stronger processing capabilities.

The four axles abroad are basically a transitional model.

However, this kind of four-axis three-linkage CNC machine tool with five-axis linkage is indeed extremely cheap.But if you export it to the Chinese market, you can sell it at a big price. Who can tell that China has huge demand and cannot produce it by itself?

If it were not for the emergence of Yunfei, China had developed a simple fourth axis since the early 1990s, causing foreign CNC manufacturers to lose at least hundreds of millions of dollars in profits on this. When China could produce this simple four-axis machine tool , China has imported at least hundreds of units from abroad!And this price has basically not dropped much since the first millions of dollars.

Even the Taiwanese factory produces at that price, which is not something ordinary people can look up to.

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

Not buying?People don't have the right not to buy.

Anyway, where is the Wasna Agreement, China wants more advanced machine tools?Dream it.

And all kinds of mechanical products, high-precision complex parts processing, these equipment is necessary, unless China has a large scientific research personnel comparable to the former Soviet Union, and everything produced is designed for special machines.

After coming to this world from Yunfei, the first step was to add a fourth axis driven by a PMC module to a three-axis CNC machining center to form a simple four-axis three-linkage function, which led to Yunfei at that time. Zhao Xingbang, who is definitely a big brother.

The ability to move the 9327 factory to Chengdu with a capital of more than 10 million yuan, and then start a business with a loan of 30 million yuan, these are all the existence 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 which belongs to the strategic factory, and when someone makes trouble for him, Li Zhongwei, the military leader, directly said that their entire military is Yunfei's backing.

This shows the importance of this technology to China.

Now, China already has five axles, but foreign countries are not allowed to export such top-level strategic equipment to China due to the provisions of the Wassenaar Agreement. This makes the five axles of Jiuyi Heavy Industry have a very large market.Moreover, the Jiuyi Research Institute has always attached great importance to confidentiality in this area.

Not long after they took out the four-axis machining center, foreign machine tool factories never thought that they could have a relatively high-precision five-axis machining center technology so quickly!

"Entering the international market, all the pressure will appear on us. In this world, no one wants our China to rise, especially the United States and Japan..." Deng Lanqing said with a serious face.

"As long as we master the five-axis technology and be announced, even if we don't enter the international market, these pressures will still appear. With the same pressure, why don't we occupy more markets?" Yun Fei smiled.

Five axes are too important for the aerospace industry.

Their large aircraft projects, 132 J-10, J-20, Shenfei J-11, many of these parts need five-axis CNC machine tools to reduce costs and improve production efficiency, otherwise, mass manufacturing is simply impossible. Things.

"How about the current control system?" Yunfei changed the subject. These things have nothing to do with researchers, and the market has nothing to do with R&D personnel.The R&D personnel he requested are only responsible for technology research and development, and nothing else.

How else can researchers waste a lot of energy on unrelated things?

"The problems of the system are not bad, mainly because the measurement technology researched by the Institute of Optoelectronics has not made breakthrough progress. 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 the main shaft okay?" Yun Fei couldn't help frowning.

Their spindle technology, but the most advanced in China, is the technology of Mazak and Mitsubishi he copied from Japan.Various material formulas and processes are all made by combining many factories.

"That is an ordinary spindle. Our motorized spindle technology has been unsuccessful. Moreover, ordinary spindles are used on five axes because they need to rotate in the A-axis and C-axis directions. Those that carry heavy loads cannot be used. Above, the newly-developed spindle has too thin walls, it will deform as soon as the heavy-load cutting test is carried out..." When it comes to this, Sun Lin has a big head.

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

Especially the finishing equipment.

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

Isn't this taking off your pants and farting?

With such expensive equipment as the five-axis machining center, which company with rich wealth would be willing to use a five-axis machining center worth tens of millions to roughen the blank?

"Yes, didn't you say that all of our machine tools must be subjected to heavy-duty cutting tests? The spindle is the most critical component. In the past few years, dozens of tests have been conducted, no matter how we modify the production process. , Modify the design scheme, can not make much progress..." Sun Lin said with a sigh.

Yun Fei suddenly wanted to slap himself.

He felt that if he listened to Sun Lin to continue talking, he would choke himself to death, because none of the many CNC machine tool manufacturers in China had done heavy-duty cutting tests, and only German Dirk that conducted such tests abroad Top machine tool factories will do it.

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

Therefore, Yunfei prevented Sun Lin from continuing to say: "Lao Sun, the five-axis machining center is originally a precision machining equipment, with tens of millions of things, who would be willing to use such equipment for rough machining?"

"Uh..." Yun Fei's words immediately made Old Sun Lin blush.

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

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

And Yun Fei did say at the beginning that all equipment must be subjected to heavy-load cutting tests, and they formed an inertial thinking. After four axes have been done, they still have to sit on five axes.Due to price issues and machining accuracy requirements for the four-axis, it is very normal for rough machining and finishing to be combined, but the five-axis cannot.

Five-axis, because of the higher accuracy, and the cheap three-axis can be used for rough contour cutting, most of the cutting allowance is eliminated, and then directly on the five-axis for finishing.

Sun Lin and the others have always entered into a misunderstanding, that is, in order to pursue high efficiency, machining centers are both rough and fine machining, especially now that many productions are single-piece and small-batch production models, and mass production is top-level manufacturing The above is often the production line.

High-end CNC machine tools are often used in cutting-edge manufacturing such as molds, aerospace and medical equipment, and the production batches of these are not too large.The mass production of parts using numerical control equipment is all assembly line processing, which is to pursue standardization while pursuing high production efficiency.

"You mean, these five-axes don't need to be subjected to heavy-load processing tests at all? Moreover, our tens of millions of funds in this area are wasted?" Sun Lin asked blushingly.

How is this not wasted?

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

But he has no way to say anything, because this is mainly the responsibility of his boss, and many research directions in the institute are designated by his boss.If you tell Sun Lin that these tens of millions are wasted, this old guy will definitely be brooding and blame himself.

"In fact, it can't be said to be a waste. In the early stage, when there were no competitors, even if the service life of these spindles was only one year, the market users would not say anything. That's not the case. If the spindle has a stronger bearing capacity, other people's machining centers can only eat 0, 05, and ours can reach 0, 1 or even 0, 2. This efficiency comparison is the most obvious..." Yun Fei I was depressed, but said with a smile on his face.

The processing cost of a five-axis machining center is 500 or 600 per hour. The higher the efficiency, the lower the cost. This is also a major selling point in this age of increasing costs.This is also a windfall.

The precision of the spindle produced by the Jiuyi Research Institute may not be comparable to that of foreign ones, but in terms of service life and durability, it will definitely exceed that of foreign spindles.You know, the production cost of the main shaft of a five-axis machining center is hundreds of thousands, and the price is at least millions!

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

"Oh!" 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 later. Only when we have a five-axis machining center in our hands, we can form a complete series with our three-axis machining center and other equipment of different grades, so that we can guarantee Sufficient market competitiveness." Yun Fei couldn't help but said, seeing the lonely expression on Sun Lin's face.
