Intelligent Industrial Empire

"Xiaoyun, the five-axis machining center we have developed at present has completely reached the market conditions, with an indexing accuracy of 0.05°, a repeat positioning accuracy of 0.02, and a machining accuracy of 0.03. The technical performance of the low-end five-axis machining center exported to us from abroad is also It's almost the same..." The Five Axis of the Jiuyi Research Institute has been in operation for so many years, and a lot of money has been invested. Sun Lin himself felt that he couldn't make it through.

Yunfei now has less and less time to arrive at the Jiuyi Research Institute. Whether any research project is put into production, Yunfei’s boss nodded and decided. This time, Yunfei has not seen anyone for almost half a year. Sun Lin put forward his own opinion-put the five-axis machining center that has just completed the research into production and then put it on the market.

Unexpectedly, before the words were finished, they were interrupted by Yun Fei who came to watch the progress.

"Lao Sun, we didn't say it right from the beginning, the machining center going out from our September 1st Research Institute must be high-quality, not these low-precision machine tools that can only perform rough machining!" For this relationship Yun Fei will not be vague at all to Jiuyi Heavy Industry, which is a sign of increasing gold content in the domestic CNC machine tool industry.

Either you don't invest in the market, and those who invest in the market must be fine products!

This is Yunfei's philosophy.

"Your kid is ugly. What is a low-end machine tool? How many domestic companies have produced it?" Deng Lanqing was not happy about Yun Fei's words.

In other words, Jiuyi Research Institute is also the first research institute in China to develop a five-axis CNC machining center. At present, even top mechanical research institutes such as the National Academy of Sciences and Huaqing University Capital University are still gnawing four. Shaft technology too!

Deng Lanqing felt that this was something to be proud of.

"The main function of the five-axis machining center is the precision machining of various difficult mechanical parts. How can this precision be processed to produce qualified parts? Especially the biggest users of this thing are the aerospace and mold industry. Sister, do you think this precision can be used for precision machining of those parts in aerospace?" Yun Fei gave Deng Lanqing a glance.

If the five-axis machining center with this precision was provided to the 132 factory, Huang Qiaosong's veteran would have to fight his own life.

The tolerances of general precision parts in aerospace are around 0.02. The five-axis machining center currently developed by Jiuyi Research Institute has only two wires of repeat positioning accuracy, and the machining accuracy cannot guarantee the accuracy range of their parts. Such products , Pushing to the market can only smash their own signs.

"This efficiency is at least twice that of an ordinary three-axis machining center!" Deng Lanqing was not convinced by this.

"Lao Sun, this matter is not in a hurry. If we want to do it, we have to hit it off and we can’t smash our own signs. If we put our five-axis linkage on the market now, in the end, those foreign machine tool factories We will definitely export more high-precision five-axis linkage without hesitation. Although it is good for our country’s defense industry, we will definitely be ruined a lot of money. These improvements in accuracy will only take a year or two at most. ." Yun Fei saw that Sun Lin still wanted to persuade him, so that directly blocked him to death.

The equipment of the Jiuyi Research Institute has an unparalleled effect on the entire CNC machine tool industry in China-prompting a substantial price reduction of similar foreign products.

The price of the three-axis machining center has been reduced from millions to five or six hundred thousand due to the sudden emergence of Jiuyi Heavy Industry. How can they not hate Jiuyi Heavy Industry?Once the September 1st Research Institute announces the success of the five-axis linkage research, it is inevitable that the domestic five-axis machining center will reduce the price. The large woodworking machines are tens of millions. Who knows how much profit is there?

Foreign countries are not China.

The markets that they open to China are generally the lowest-end and worst-accuracy five-axis linkages. Even, most of them are five-axis three linkages or five-axis four linkages. The five-axis five linkages started last year. China has been negotiating with Japan, but still has not got the goods.

If this is brought to the market now, it will become Tian Ji Racing. Foreign machine tool factories use low-end machine tools to fight price wars with Jiuyi Heavy Industries, and then they invest high-precision machine tools in the Chinese market to earn losses in the low-end market. interest.

In the end, the five-axis that Jiuyi Heavy Industry spent a lot of money did not make much profit. However, foreign machine tool factories still use their high-precision machine tools to make large-scale profits, and Jiuyi Group still suffers.

"The main reason is that the control accuracy of the control system is a bit poor. For the mechanical part, our electric spindle technology has not been very mature. These problems cannot be solved in a short time..." Sun Lin wanted to tell Yun Fei, one or two The estimate for the year is a bit optimistic.

"Old Sun, I understand what you mean, one or two years will not work, only three years, three years not, five years. We can afford it!" Yun Fei said categorically.

Sun Lin was worried that he would lose confidence in this because he could not see the benefits for a long time. Anyway, even if he sells three-axle and four-axle, it is enough for 91 Heavy Industries to earn enough profits.

In this era, few Chinese companies are willing to invest heavily in research and development, especially private owners.

Even Huadu CNC, the number one manufacturer of CNC systems in China, has not developed a true four-axis control system. Instead, it has invested in the simple CNC system that has the greatest demand from market users.

Research on the roller screws and AC servo motors that match the CNC system has not made much market progress, because most of their drives use stepper motors!

"The key is the issue of research funding..." How can Deng Lanqing not know what Sun Lin thinks!

"Am I less than the research funding of the Academy?" Yun Fei was speechless.

Isn't this discrediting yourself?

"The last time President Jiang reduced the research funding, and later said that it would be restored, but now this quarter is about to pass, and there are still tens of millions of research funding that has not been in place. If it is not based on the technology of the wheat factory and the Xingmeng company A lot of research on user fees will come to a halt..." Deng Lanqing is not afraid that Yun Fei said she misappropriated funds.

They didn't spend the money indiscriminately anyway.

"Didn't the money of those two companies go to the accounts of the head office? Why did it get into the research institute?" Yun Fei is most sensitive to money now, especially about embezzlement.

"Borrowed! I have already started to advance the money for the next quarter. If this continues, we will probably owe our research funding for several years..." Deng Lanqing said with a pouted mouth.

Seeing Yun Fei frowned, his brows suddenly curled: "Or, let's stop the research on flexible manufacturing systems? We will do our best to work on five-axis and other projects before we do this? There are also robot projects that stop... …"

"Come on, the radical method is of no use to me. In the future, it is best to do less, do research, and do research steadily. Don't worry about finances, otherwise it won't be easy to explain things later... …" Although she knew that a woman like Deng Lanqing would not embezzle research funds for her own personal gain like Wang Bingkun did, Yun Fei felt that she should still be beaten.

He can't tolerate others taking money from his wallet, even if it is spent on him, he can't tolerate it.

Classmate Yun Fei’s cheese is absolutely not allowed to move.

Whoever moves, he is anxious!

"Would you like to go to the experimental workshop?" Sun Lin felt that Yun Fei's words were a bit heavy. In case he provokes Deng Lanqing, this girl is a bitch, and many projects in the Institute of Mechanical Engineering are going to be messy .

"I'm definitely going to have a look. I won't go out during this time, and I'll be banned. It just happened to be in the research institute..." Yun Fei blinked at Deng Lanqing who stared at him fiercely.

The test workshop has not changed much. The only difference is that there are more and more areas separated by glass.

For so many years, the results of the mechanical technology research of the Jiuyi Research Institute have been divided into small areas in this workshop.

"How is the progress of the turning-milling composite machining center for the Three Gorges?" Yun Fei strolled around in the workshop and couldn't help being a little surprised when he didn't see the area of ​​the project.

He grabbed the birthplace of this project from Wuhan Heavy Machinery. If the task is not completed by that time, the power generation of the first unit that affects the Three Gorges Dam will definitely be cleaned up.

"You can still think of this project, it's incredible..." Deng Lanqing curled his lips and gave Yunfei a white glance.

This guy Yun Fei is like that. Many times he spends a lot of energy to get a project, turns his head and throws it away, and then he will not bother for a long time.

"If I can't remember, would I ask this?" Yun Fei was speechless.

Why is this woman more and more like to behave with herself now?Could it be...

This simply made Yun Fei dare not imagine.

Last time Deng Lanqing pulled him to XXOO with him, and asked him to borrow a seed. The Yunfei he had done was a runaway. Before he came here today, why did he forget this?

This is a terrible thing!

You have to keep a distance from this woman, you have to tighten your belt, or else, the consequences are really beyond him!

"Assembling and debugging have started now. If you wait for you to intervene in person, it is estimated that the day lily will be over..." Deng Lanqing suddenly discovered that rolling his eyes at Yun Fei is a pleasant thing both physically and mentally.

"Not in our workshop?" Yun Fei was suddenly taken aback.

The Jiuyi Research Institute is the general contractor of this project!

"Although our workshop site was sufficient at that time, it was not easy for such a big guy to be transported from Chengdu. The carriages of the train couldn't fit at all. After we discussed with the people of Haar Heavy Industry and Northern Heavy Industry, we put the assembly in. At Haer Heavy Industry, the runner of the water turbine is processed in the northeast, which also saves millions of transportation costs..." Sun Lin explained to Yunfei.

If Deng Lanqing were to be nonsense with Yun in this way, she wouldn't be able to talk about it in one day.

"In this way, if there is any need to coordinate, it is not very troublesome?" Jiuyi Research Institute is responsible for the control system, Haer Heavy Industry is responsible for providing technology for heavy lathes, Northern Heavy Industry is responsible for milling machine technology, and finally the Jiuyi Research Institute is responsible for the assembly .

"All three of us have drew up our capable power to Haer Heavy Industry. We are personally responsible for Situ. In addition, Lao Cao also specially designed a control system, plus some old guys from the National Institute of Machinery We assist, there will be no problem..."

"No wonder I didn't see him!" Yun Fei understood.

Now he himself feels that his boss is a bit irresponsible.

This was a big deal for their group company, but it was because of anger with the big leader and the second leader to grab the project. Since then, he has never even asked about this.

There are also people like Jiang Jianxing and Sun Lin. Otherwise, it is estimated that they would have been called to his office by the second leader. They are very good training!

"How many knives have we designed for the tool magazine of the five-axis machining center?" Yunfei didn't bother to look at the five-axis woodworking machine.

That thing is not mainstream.

If you want to do it, you have to do a heavy five-axis!

Of course, in line with the principle that no matter how small a mosquito is, it is still fleshy. The progress of the research on woodworking machines by the Jiuyi Research Institute has kept pace with the development of heavy five-axis linkage machine tools.In particular, the turning-milling composite machining center supporting the Three Gorges has been successfully researched, and after it is delivered to use, it will definitely be of great benefit to them.

Especially in the design and manufacture of heavy-duty multi-axis linkage CNC machine tools, otherwise Yunfei would not risk offending the leaders of the two leaders and smash the table with them to snatch the fat of Wuhan Heavy Machinery.

Facing the semi-finished product of the 2000×1200 dual-spindle five-axis vertical and horizontal dual-use heavy-duty CNC machining center in front of him, Yun Fei frowned and asked.

This thing, he insisted on asking for such a design, no matter in the domestic market or the international market, there is no such design.Sun Lin was also very opposed to Yunfei's doing this at the beginning, but if he is the boss, he must be executed, right?

Ever since, there is such a thing that subverts the traditional design.

This was Yun Fei's idea of ​​earning a living when he heard those masters discussing when he was working as a technician when he was working as a technician.He didn't have the opportunity to verify his idea before, but now, given the opportunity, he must definitely try it out.

It's his thoughts, it's such a thing in front of him that has cost more than 30 million yuan!

This is a combination of a horizontal machining center and a vertical gantry machining center. It must look weird and awkward.And the gantry-type vertical machining center, that is, the upper spindle can move back and forth, but the column cannot move left and right, and the left and right movement mainly depends on the table.

Both spindle systems use the same chain-type tool magazine.

This makes the design more difficult. This has been done for more than two years, and a lot of parts have been scrapped to achieve the current progress.

"One hundred and twenty tools, but the two spindle heads you requested can be processed at the same time. So far, it has not been realized. In the processing engineering, it is easy to interfere. If our control technology does not have breakthrough progress , Yours is not much better than foreign machining centers that can be converted from vertical to horizontal. Perhaps you will be despised by users because this design is too cumbersome..." For this, Deng Lanqing felt that But this is a bit whimsical.

This is a subversion of the traditional design, but also because of this design, the volume of the entire device is one-third larger than that of the same type.

If the two spindles can be processed at the same time successfully, this design can be called a genius design. If not, this design is completely superfluous.

The volume is one-third larger, but the manufacturing cost and manufacturing difficulty are more than doubled.

"I don't despise it. You have to wait until the research is successfully launched to the market. Don't draw conclusions so early!" Sun Lin said dissatisfied with his closed disciple.

The most afraid of doing research is to rely on your own judgment to get the result before there is any result.

"Dual spindles cannot be processed at the same time. Why? Interference with each other during processing, or the delay of control signals?" Yun Fei still knows a little bit about these things.

The main difficulty of this design for two spindles to process two different surfaces at the same time lies in the two aspects he proposed.The problem of interference is still easy to solve, mainly because the two spindles cannot be synchronized.

The above spindle machining has to move in one direction, while the horizontal spindle has to move in another direction, which makes the control difficult during the machining process, and it may cause tool collision.

"The main thing is the control signal delay and a large amount of data processing. At present, this device uses more than 400 32-bit industrial control chips, which makes the control signal jump too many times..." Sun Lin said with a wry smile.

The boss moved his mouth, his man broke his leg...

"Tanalia hasn't gotten 64 chips yet?" Yun Fei frowned and asked.

How long has this chip been made?

"It came out, but the current performance is very unstable. Even if it does, if our control system can't keep up, it's no use. The old Cao said several times that he wanted to find you hard..." Deng Lanqing smiled to Yunfei Said.

She still knew how Yun Fei fooled Cao Zhijiang. As a result, when she came to Jiuyi Research Institute, she faced the problem of developing several control systems at the same time.

This makes the old man's head bigger.

What Yunfei can do is that the three-axis system copied other people's designs.

In fact, it proved that he copied several systems to create a numerical control system, which has no development potential at all, and he can't even continue to expand...

The development of Huadu CNC is slow. For so many years, they have not launched their own high-end CNC system or improved four-axis or even five-axis linkage control system based on the design of Long CNC system.

The number of flowers was pitted by Yun Fei, a half-hearted designer!

"..." Yun Fei was speechless.

"Let's do this slowly. Even if it is done, it is estimated that the market prospects will not be too great. This thing is too high-end..." Yun Fei said comfortingly.

"You can't talk about high-end technology, but after it is made, the price is definitely high-end..." Regarding Yun Fei's idea, Deng Lanqing looked at him once and laughed at him once anyway.

"Don't worry, it's really done. There will definitely be users. If you can't sell it, you can throw a few units into Lao Wang's Xinkaixing, and then drop a few units into the 132 factory, Dongqi, etc. Let them get one or two of them back, and the cost will come out..." Yun Fei said disapprovingly.

In fact, the most important user of such a design is the processing and production of high-precision heavy parts.

When Yun Fei was opposed by Sun Lin at the beginning, he didn't even think about whether he could sell it. This was one of his dreams!

Only by surpassing those foreign giants in design concepts, can it be possible to compete with them in technology.

"Xiao Yun, don’t listen to Xiao Deng. A few days ago, Lao Huang from 132 brought a group of people to our side to watch the progress of the five-axis. He is very interested in this type of heavy-duty machine tool, but he just dislikes our processing. The scope is a bit small..." Sun Lin also knew that state-owned units are the main market users for these top-level machine tools.

And state-owned units that dare to buy such equipment will only care about the processing accuracy, performance, and price issues, which are rarely considered.

This kind of machining center will be more than double the efficiency of ordinary machine tools for the processing of box parts and large molds!Moreover, the two spindles of the tool can be called mutually, which is definitely an artifact for some complex parts processing.

"Oh? Which factory leader has such a vision?" Yun Fei was really surprised by such a thing.

"It seems to be a gearbox factory over Shancheng, and an automobile engine factory..."

Yun Fei nodded, such potential customers must have a good relationship.

He has no worries about selling other five-axis machining centers. But this one is his own design concept. If this one can sell thirty or fifty sets, it will definitely make him better than other five-axis machining centers. I'm still happy to sell three to five hundred units.

Several other types of five-axis machining centers in the test workshop have basically been finalized. What is needed now is to continuously improve accuracy and conduct various tests. These are some technical problems. To solve them, it is no longer his Things that a half-hearted boss can solve.

Starting from the four-axis machining center, Jiuyi Research Institute has basically begun to spend money on technology.

Not enough researchers?Then let Chen Jie take the money to smash it. As long as it is a really skilled person, he should give it as much as he wants. Of course, it has to produce results!

Not enough research funding?Let Zhang Cui transfer from my private account to the research institute. Can we, the richest man in mainland China, make this money?

Not enough technology?There is no way...

"By the way, kid Yun, have you thought about building an underground research workshop?" Sun Lin stopped Yun Fei when he saw Yunfei was going to the test workshop of flexible manufacturing.

"How did you think about it? How about using the internal workshop of the Ninth Hospital to renovate the mountain, or just build a workshop underground?" Yun Fei was stunned. He really hadn't considered this matter.
