Chapter 761

"Xiaoyun, at present, the five axis machining center we have developed has completely met the conditions for listing, with indexing accuracy of 0.05 °, repeated positioning accuracy of 0.02 and machining accuracy of 0.03, which is not much different from the technical performance of low-end five axes exported to us..." the five axes of 91 research Institute have been engaged in for so many years and have invested a lot of funds, Sun Lin felt that he couldn't get through it.

Yunfei now has less and less time to go to the 91 Research Institute. Whether any research project is put into production or not depends on the boss of Yunfei. This time, Yunfei has not seen anyone for almost half a year. As soon as he saw it, Sun Lin put forward his own opinion - let the five axis processing center just completed the research be put into production and then put it on the market.

Unexpectedly, before he finished speaking, he was interrupted by Yunfei who came to watch the progress.

"Mr. Sun, we agreed at the beginning that the machining centers going out from our 91 research institute must be high-quality products, not some low-precision machine tools that can only carry out rough machining!" Yun Fei will not be vague about this matter, which is related to Jiuyi heavy industry, a signboard with more and more gold in the domestic CNC machine tool industry.

Or do not invest in the market, invest in the market, must be high-quality products!

This is the concept of cloud non.

"Your boy is ugly. What is low-end machine tool? How many companies in our country have come out? " Deng Lanqing is not happy about Yunfei.

How to say, the 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 and Capital University are still gnawing at the four-axis technology!

Deng Lanqing felt that this was something he could be proud of.

"The main function of the five axis machining center is the precision machining of various difficult mechanical parts. How can we process qualified parts with this precision? In particular, the biggest users of this thing are aerospace and mold industry. Sister Deng, do you think such precision can be used for the precision machining of aerospace parts? " Yun feibai glanced at Deng Lanqing.

If the five axis machining center with this accuracy is provided to factory 132, Huang qiaosong's old goods will have to fight his old life with him.

The tolerance of general precision parts in aerospace is about 0.02. At present, the repeated positioning accuracy of the five axis machining center developed by Jiuyi Research Institute is only two wires, and the machining accuracy can not guarantee the precision range of their parts. Such products can only smash their own signboard when they are introduced to the market.

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

"Mr. Sun, this matter is not urgent. If we want to do it, we have to be popular at once. We can't smash our own signboard. If we push our five axis linkage to the market now, in the end, those foreign machine tool factories will not hesitate to export higher precision five axis linkage. Although it is good for our national defense industry, we will definitely be wronged with a lot of money. These improvements in accuracy will take only a year or two at most. " Seeing that Sun Lin still wanted to persuade him, Yunfei blocked him directly.

These equipment of the Jiuyi Research Institute have an unparalleled role in the whole Chinese CNC machine tool industry - promoting the substantial price reduction of similar foreign products.

The price of three-axis machining center has been reduced from millions to 5.6 million because of the sudden rise of 91 heavy industry. How can they not hate 91 heavy industry? Once the 91 Research Institute announces the success of the five axis linkage research and the price reduction of domestic five axis machining centers, it must be inevitable. There are tens of millions of large woodworking machines. Who can not know how much profit there is?

Foreign countries are not China.

The markets they open to China are generally the lowest end and the worst precision five axis linkage. Even, most of them are five axis three linkage or five axis four linkage. Since last year, China has been negotiating with Japan, but it still hasn't got the goods.

If we push this to the market now, it will become Tianji horse racing. Foreign machine tool manufacturers use low-end machine tools to fight a price war with 91 heavy industry, and then they invest high-precision machine tools in the Chinese market to earn the benefits lost in the low-end market.

In the end, the five axes smashed out by Jiuyi heavy industry did not make much profit. However, foreign machine tool factories still use their high-precision machine tools to make large-scale profits, and the loss is still Jiuyi group.

"Now the main reason is that the control accuracy of the control system is a little poor. As for the mechanical part, our motorized spindle technology has not been very mature. These problems can not be solved in a short time..." Sun Lin wanted to tell Yun Fei that the estimation in one or two years is a little optimistic.

"Mr. Sun, I see what you mean. If you can't do it in one or two years, just three years, three years, five years. We can afford it! " Yun Fei said firmly.

Sun Lin was worried that he would lose confidence in this because he could not see benefits for a long time. Anyway, even if he sold three-axis and four-axis, it would be enough for 91 heavy industry to earn enough benefits.

In this era, few Chinese enterprises are willing to invest heavily in R & D, especially private bosses.

Even Huadu CNC, the first CNC system manufacturer in China, has not even developed a real four-axis control system. Instead, it has invested its research direction in the simple CNC system with the largest demand from market users.

The research on roller screw and AC servo motor matched with NC system has not made much market progress, because most of their transmission adopts stepping motor!

"The key is the problem of research funds..." Deng Lanqing doesn't know what Sun Lin thinks!

"Do I have less research funds than the research institute?" The cloud was speechless.

Isn't this a smear of yourself?

"Last time President Jiang reduced the research funds, and later said he wanted to restore them. However, this quarter is about to pass, and tens of millions of research funds are not in place. If it weren't for the technology royalties from the wheat factory and Xingmeng company, many research would come to a standstill... "Deng Lanqing was not afraid of Yun Fei saying that she misappropriated funds.

They didn't spend the money anyway.

"Didn't the money of those two companies go into the head office's account? How did you get to the research institute? " Yunfei is now the most sensitive to money, especially misappropriation.

"Borrowed! Now we have begun to advance money for the next quarter. If we continue to do so, we will owe our research funds for several years... "Deng Lanqing said with a curly mouth.

Seeing that Yun Fei frowned, he immediately bent his eyebrows: "why don't we stop the research on flexible manufacturing system? Try your best to get five axes, and then do this after the project? And the robot projects all stop... "

"Come on, it's no use to me. In the future, it's better to do less research and do research in a down-to-earth manner. Don't move on the financial level, otherwise it's hard to explain things later... "Although I know that female Han paper such as Deng Lanqing won't misappropriate research funds for personal gain like Wang Bingkun, Yun Fei feels that she should beat this girl.

He couldn't tolerate others taking money from his money bag, even if it was spent on him.

Yunfei's cheese is absolutely not allowed to be moved by others.

Whoever moves, he's in a hurry!

"Would you like to go to the experimental workshop?" Sun Lin feels that Yunfei's words are a little heavy. In case he provokes Deng Lanqing, the girl will kick. Many projects in the Machinery Research Institute will have to lie down.

"I must go and have a look. I won't go out during this time. I'm banned. Just in the research institute to spend time... "Yun Fei winked at Deng Lanqing who stared at him.

The only difference is that more and more areas are separated by glass.

Over the years, the mechanical technology research achievements of the 91 Research Institute have been divided into small areas in this workshop.

"What's the progress of the turning milling compound machining center supporting the Three Gorges?" Yun Fei wandered around the workshop and was stunned that he didn't see the area of the project.

He snatched this project from the five Han heavy machinery. If he can't complete the task and affect the power generation of the first unit of the Three Gorges Dam, he will definitely be cleaned up.

"You can still think of this project. It's amazing..." Deng Lanqing glanced at Yun Fei.

Yunfei is such a guy. He often spends a lot of energy on getting the project, turns around and loses it, and won't bother for a long time.

"If I can't remember, would I ask this?" Cloud Fei is speechless.

Why does this woman like to quarrel with herself more and more now? Is it

This simply makes Yunfei dare not imagine.

Last time Deng Lanqing took him to have sex with him and asked him to borrow some seeds. It was Yunfei who ran away. How could he forget this stubble before coming today?

This is a terrible thing!

He must keep a distance from this woman and tighten his belt. Otherwise, he can't bear the consequences!

"Now the assembly and debugging have started. If you come and ask in person, it's estimated that the cauliflower will be gone..." Deng Lanqing suddenly found that it's a pleasant thing to roll your eyes at Yunfei.

"Not in our workshop?" Yun Fei was a little stunned.

The 91 Research Institute is the general contractor of this project!

"Although our workshop site was sufficient at that time, it was not easy to transport such a big guy from Chengdu. The train carriage could not be loaded at all. After discussion with the people of Hal heavy industry and Northern heavy industry, we put the assembly to Hal heavy industry, and the runner of the water turbine was processed in the northeast, It also saves millions of transportation expenses... "Sun Lin explained to Yun Fei.

If Deng Lanqing is allowed to talk nonsense with Yun like this, he won't talk about the subject in a day.

"In this way, if there is anything to coordinate, it is not very troublesome?" Jiuyi Research Institute is responsible for the control system, Hal heavy industry is responsible for providing the technology of heavy lathe, northern heavy industry is responsible for the technology of milling machine, and finally the assembly is carried out by Jiuyi Research Institute.

"The three of us have taken out our capable forces to Hal heavy industry. Situ is personally responsible for us. In addition, Lao Cao has specially designed a set of control system. With the assistance of some old friends of the National Machinery Research Institute, there will be no problem..."

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

Now he feels that he is a bit irresponsible as a boss.

This is a major event of their group company, but he was angry with the big leader and beat the table with the second leader before he grabbed the project. Since then, he has never been involved in this matter.

There are also people like Jiang Jianxing and Sun Lin, otherwise they would have been called to his office by the second leader. It's a good training!

"How many knives are designed for the tool magazine of our five axis machining center?" Five axis woodworking machine, Yun Fei is too lazy to see.

That thing is not mainstream.

If you want to do it, you have to do heavy five axes!

Of course, in line with the principle that no matter how small a mosquito is, it is also meat. The research progress of the 91 Research Institute in woodworking machines goes hand in hand with the heavy five axis linkage machine tools. In particular, the turn milling compound machining center supporting the Three Gorges has been successfully studied and put into use, which is absolutely of great benefit to them.

Especially in the design and manufacture of heavy multi axis CNC machine tools, otherwise Yunfei would not take the risk of offending the second leader and beat the table and the bench with them to rob the fat of the five Han heavy machine.

In front of this work area 2000 × The semi-finished product of the 1200 double spindle five axis vertical and horizontal dual-purpose Heavy CNC machining center, Yun Fei asked with a frown.

He insisted on this design. There is no such design in both the domestic market and the international market. Sun Lin was also very opposed to Yun's insistence at the beginning, but if he was the boss, he had to implement it, didn't he?

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

This is Yun Fei's idea of making a living when he heard those teachers talking about doing some heavy parts when he was a technician. He didn't have a chance to test his idea before, but now, when he has a chance, he must let someone try it out.

It's his idea, the thing in front of him, which has cost more than 30 million!

This is a combination of a horizontal machining center and a vertical gantry machining center. It must look a little strange and awkward. The gantry type vertical machining center, that is, the upper spindle can move back and forth, while the column cannot move left and right. The left and right movement mainly depends on the workbench.

Both spindle systems use the same chain magazine.

This makes the design more difficult. It has been done for more than two years, and a lot of waste parts have made such progress.

"120 knives, but the two spindle heads you require can be processed at the same time. So far, it has not been realized. It is easy to interfere in the processing engineering. If our control technology has not made a breakthrough, you are not much better than the foreign processing center that can carry out vertical and horizontal conversion, Maybe users will despise this design because it is too cumbersome... "For this, Deng Lanqing feels that Yunfei is a little whimsical.

This subverts the traditional design, but also because of this design, the volume of the whole equipment is one-third larger than that of the same type.

If we can successfully realize the simultaneous processing of double spindles, this design can be called a genius design. If we can't, it's a design that adds to the snake.

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

"Despise do not despise, this has to wait until the research is successfully introduced to the market, will know, don't draw a conclusion so early!" Sun Lin said dissatisfied with his closed door disciple.

The most fear of those engaged in research is to rely on their own judgment when there is no result.

"Double spindle can't be processed at the same time. What's the reason? Do they interfere with each other during processing, or the delay of the control signal? " Yun Fei still knows a little about these things.

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

The spindle above needs to move in one direction, while the horizontal spindle needs to move in another direction, which makes it very difficult to control in the processing process. If not, there will be a knife collision.

"Mainly control signal delay and large amount of data processing. At present, more than 400 32-bit industrial control chips are used on this equipment, which makes the control signal jump too many times... "Sun Lin said with a bitter smile.

The boss moved his mouth and his men broke their legs

"Tanalia, the 64 bit chip hasn't been worked out yet?" Yun Fei asked with a frown.

How long have you been working on this chip?

"It's out, but the current performance is very unstable. Even if it's out, it's useless if our control system can't keep up. An old Cao has said many times that he wants to work hard for you..." Deng Lanqing said to Yun Fei with a smile.

Yunfei knew how to deceive Cao Zhijiang. As a result, the Institute was faced with the problem of developing several control systems at the same time.

This makes the old man's head big.

What the cloud can't do, that is, the three-axis system plagiarizes other people's designs.

In fact, it has been proved that the CNC system he made by copying several systems has no development potential at all, and he can't even continue to expand

Huadu CNC has made slow progress. 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 dragon CNC system.

The number of flowers was dented by Yunfei, a half hanging designer!

"..." cloud is not speechless.

"Do it slowly. Even if it is done, it is estimated that the market prospect will not be too big. This thing is too high-end..." Yun Fei comforted himself.

"You can't talk about high-end technology, but after you get it out, the price is definitely high-end..." for the idea of Yun Fei, Deng Lanqing looked at him once and laughed at him once.

"Don't worry, if it's really done, there will definitely be users. If it can't be sold, throw a few units into Lao Wang's xinkaixing, and then throw a few units into plant 132, Dongqi or something. The family asked them to get one or two back, and the cost will come out..." Yun Fei said with surprise.

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

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

Only by surpassing those foreign giants in design concept can we compete with them in technology.

"Xiao Yun, don't listen to Xiao Deng. A few days ago, Lao Huang, 132, came to us with a group of people to see the progress of five axes. He was very interested in this type of heavy machine tools, but he thought our processing scope was a little small..." Sun Lin also knew that the state-owned units were the main market users of these top machine tools.

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

This kind of machining center, for the processing of box parts and large molds, the efficiency will be more than twice that of ordinary machine tools! Moreover, the two spindles of the tool can call each other, which is absolutely an artifact for the processing of some complex parts.

"Oh? Which factory leader has such vision? " For such a thing, Yun Fei really felt a little surprised.

"It seems that there is a gearbox factory in the mountain city and an automobile engine factory..."

Yun Fei nodded. Such potential customers must have a good relationship.

He doesn't worry about selling other five axis machining centers, but this one, but his boss Yunda's own design concept, if he can sell 30 or 50 sets, it will definitely make him happier than other five axis machining centers.

Several other models of five axis machining centers in the test workshop have basically been finalized. What we need now is to continuously improve the accuracy and carry out various tests. These are some technical problems that can not be solved by his half hearted boss.

From the four-axis machining center, the 91 Research Institute basically began to use money to smash technology.

Not enough researchers? Let Chen Jie smash it with money. As long as it's a really skilled person, give as much as you want. Of course, you have to make achievements!

Insufficient research funds? Let Zhang Cui transfer from my private account to the Research Institute. Can the richest man in mainland China have this money?

Not enough technology? There's no way

"By the way, cloud boy, have you considered the matter of building an underground research workshop?" Seeing that Yunfei was going to the flexible manufacturing test workshop, Sun Lin stopped Yunfei.

"What do you think? What is the use of the internal workshop in the mountain of the Jiuyuan base, or is it to build a workshop here underground? " Yun Fei was stunned. He really didn't think about it.
