Smart Industrial Empire

Therefore, no matter from which point of view, the export of Jiuyi Heavy Industry's CNC machine tools is imperative. ..If they are hiding in the country, those big bosses have a reason to suppress them.

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

Internationally, the market for four-axis machine tools is not as huge as five-axis. Many parts that require four-axis processing do not require high precision and high processing costs. They often use a rotary table controlled by PMC to form the fourth axis. Simple four-axis machine tool processing; and parts or products that require high precision basically do not have much requirements for cost, all of which use five-axis linkage CNC machine tools with stronger processing capabilities.

The foreign four-axis is basically a transitional model.

However, compared with the five-axis four-axis three-linkage CNC machine tool, it is indeed extremely cheap.However, if exported to the Chinese market, it can be sold at a high price. Who said that China has an extremely huge demand and can't produce it by itself?

If it wasn't for the emergence of Yunfei, China has developed a simple fourth-axis since the early 90s, causing foreign CNC manufacturers to lose at least hundreds of millions of dollars in profits. When China was able to produce this simple four-axis machine tool, China At least hundreds of units have been imported from abroad!And this price has basically not dropped much from the initial million dollars.Update 933 Five-axis is the basis for entering the international market. Even if it is produced by a factory in Taiwan, the price is not something 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 foreign exchange is earned by Taiwan and foreign CNC manufacturers.

Not buying?If you don't buy, you don't have the right.

Anyway, where is the Wassenaar Agreement? China wants more advanced machine tools?dream.

Moreover, all kinds of mechanical products and high-precision complex parts processing must require these equipments, unless China has a huge scientific research personnel comparable to the former Soviet Union.Everything we produce is a special plane.

After Yunfei came to this world.The first is to install the fourth axis driven by the pmc module on the three-axis CNC machining center to form a simple four-axis function of four-axis three-linkage, which led to Zhao Xingbang, who was definitely a big boss for Yunfei at that time, through Kmat.

Being able to relocate the 1000 factory to Rongcheng with more than 937 million yuan of funds, and then start with a loan of 3000 million yuan, all these are the existence of this simple four-axis technology.Strictly speaking, Yunfei started with this project.No military support.It was impossible for him to contract the 937 belonging to the strategic factory, and when someone troubled him, Li Zhongwei, the military boss, directly said that their entire military was Yunfei's backer.Update 933 The five-axis is the basis for entering the international market. This shows the importance of this technology to China.

Now, China already has five axes.However, due to the provisions of the Wassenaar Agreement, foreign countries are not allowed to export such top-level strategic equipment to China.This makes Jiuyi Heavy Industry's five-axis have a very huge market.Moreover, the Jiuyi Research Institute has always attached great importance to the secrecy of this aspect.

Not long after the four-axis machining center was released, foreign machine tool manufacturers never imagined that they could have relatively high-precision five-axis machining center technology so quickly!

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

"As long as our five-axis technology is released, even if we don't enter the international market, these pressures will still appear. The same pressure. Why don't we occupy more markets?" Yun Fei laughed.

five axis.It is too important for the aerospace industry.

Their large aircraft project, 13 J-[-] and J-[-].For Shen Fei's J-[-], many of these parts require five-axis CNC machining to reduce costs and improve production efficiency. Otherwise, large-scale manufacturing is simply impossible.

"How is the current control system?" Yun Fei changed the topic. These things have nothing to do with researchers, and the market has nothing to do with developers.The R&D personnel he requested are only responsible for technology research and development, and do not care about anything else.

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

"The problem of the system is not bad. The main reason is that 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 there no problem with the spindle?" Yun Fei couldn't help frowning.

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

"That's an ordinary spindle. Our electric spindle technology has been researched without success. 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. In this regard, the newly developed spindle is too thin, and it will deform when it is subjected to heavy-load cutting tests..." When Sun Lin mentioned this, his head grew dizzy.

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

Especially finishing equipment.

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

Isn't this just taking off your pants and farting?

With such expensive equipment as a five-axis machining center, which rich and powerful company would be willing to use a five-axis machining center worth tens of millions to rough-machine the blank?

"That's right, 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 carried out, no matter how we modify the production process. Even modifying the design plan will not make much progress..." Sun Lin said with a sigh.

Yun Fei immediately wanted to slap himself a few times.

He felt that if he listened to Sun Lin continue, he would strangle himself to death, because none of the many CNC machine tool manufacturers in China had done heavy-duty cutting tests, and the only foreign company that had done such tests was Germany's Dirk. Only the top machine tool factories will do it.

Because there is no need at all, CNC machine tools rarely process blanks.

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

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

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

Sun Lin never expected to make such great progress so quickly.

And Yunfei did say at the beginning that all equipment must be subjected to heavy-duty cutting tests, and they formed an inertial thinking. After doing four-axis, five-axis still has to sit.Due to price issues and processing accuracy requirements for four-axis, it is very normal for rough machining to be combined with finish machining, but not for five-axis.

Five-axis, because of the higher precision, and the cheap three-axis can be used for rough machining by rough contour cutting, most of the allowances that need to be cut are removed, and then the five-axis can be directly used for finishing.

Sun Lin and the others have always entered into a misunderstanding, that is, they think that in order to pursue high efficiency, machining centers are all rough and fine machining together, especially now that many productions are single-piece and small-batch production models, and mass production is in the top manufacturing In the world, it 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 quantities of parts is processed by CNC equipment, which is the pursuit of standardization and high production efficiency.

"You mean, these five-axis machines don't need heavy-duty machining tests at all? Besides, our tens of millions of dollars in this area are wasted?" Sun Lin asked with a blushing face.

How is this not wasted?

Yun Fei suddenly felt that his heart was bleeding. This is 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 research institute are designated by his boss.If you tell Sun Lin that the tens of millions were wasted, the old guy will definitely be bitter 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, market users would not say anything. This is not the case anymore. If the spindle has a stronger bearing capacity, other people’s machining centers can only eat 1, [-], and ours can reach , [-] or even , and this efficiency comparison is the most obvious…” Yun Fei was depressed in his heart, but his face But he said with a smile on his face.

The processing cost of a five-axis machining center is five or six hundred per hour. The higher the efficiency, the lower the cost. In this era of increasing costs, this is also a major selling point.This can be regarded as a windfall.

The precision of the spindle produced by Jiuyi Research Institute may not be comparable to that of foreign spindles, but it will definitely exceed the spindles of foreign countries in terms of service life and solidity.You must know that 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 better the machining accuracy. This is a good thing for our brand!"

"Hey!" 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, which can form a complete series with our three-axis machining center and other equipment of different grades, can we guarantee Sufficient market competitiveness." Seeing the lonely expression on Sun Lin's face, Yun Fei couldn't help saying this. )
