Smart Industrial Empire

Guocheng Impeller Factory is the first professional impeller manufacturer in China. Although it has just started construction and has not been officially put into operation, even trial production has not yet started. The impellers of steam turbine manufacturers such as Harbin Steam and Dongqi The Chinese manufacturers who have always relied on imports have long been looking forward to having a professional impeller manufacturer in China to support them.

The impeller not only has high requirements for production materials, but also has higher requirements for processing technology. This is a complex three-dimensional surface processing, and it requires one-time processing for each process.

Not one side is processed and formed at one time, but two sides are processed and formed at one time. Only in this way can the accuracy be guaranteed.

This requires very high machining accuracy of the equipment.

The four-axis machining center produced by Jiuyi Heavy Industry has filled the gap of domestic high-end equipment in the domestic market. In the processing of complex three-dimensional curved surfaces such as impellers, it not only improves efficiency, but also effectively reduces production costs.

Of course, it is still relatively difficult to process the impeller with a four-axis machining center.

"When will the five-axis machine at the September [-] Research Institute be able to produce it? It's still a bit difficult for the four-axis machining center to produce these distorted three-dimensional surfaces..." The laboratory was not built yet, so Yun Fei didn't bother to go there to see it.

Moreover, some simple physical and chemical analyzes as well as impact and tensile tests are done on the materials now, and the testing methods for the processed finished products are not complete.Even if he went to the laboratory, he was just looking at the flowers on horseback, and couldn't see anything. He had already read too much in Jiuyi Materials.

A few people simply went to the machining workshop.

This is the industry where Yunfei started. Although his current scale in this industry is not large, his strength in processing technology, complete processing equipment, and precise processing technology are recognized as the number one in the whole country.

Now even in some large old state-owned factories, the processing of many new products is lost to Xinkaixing, and most of the parts of the state-owned military factories that have not completed the technical equipment update are also handed over to Xinkaixing for processing.

Moreover, the means and precision of machining are complementary to the CNC machine tools produced by Jiuyi Heavy Industry.mutually reinforcing.As long as Jiuyi Heavy Industry produces any new product, Xin Kaixing will be the first user.

Many domestic machinery companies have visited Xinkaixing to learn their advanced management concepts and processing methods. It is basically a model factory for large-scale processing demonstrations of Jiuyi Heavy Industry and North Heavy Industry.

The choice of processing mode, the scope of use of processing equipment, the selection of various parameters, staffing and so on.It is the most advanced in the whole of China, because Yunfei proposed from the very beginning that it is necessary to obtain benefits from management and profit from management.

The management cost of Xinkaixing is indeed very low.

Otherwise, Xin Kaixing's machining business.It is impossible to have such a high profit.

"The five-axis is indeed the most suitable for the processing of complex surface parts such as impellers, but the current machining accuracy is still relatively poor, and the numerical control system has not made much progress. If it is used for the production of some complex parts that do not require particularly high precision , there is no problem, but in that case, the cost of this equipment will be too high. When it comes to the processing of some difficult parts, it can only be used for roughing (rough processing)..." Yun Fei sighed.

The machining of the impeller, which belongs to the spiral twisted three-dimensional curved surface, and the machining of the four-axis machining center, mainly rely on the fourth axis of rotation, that is, the b-axis keeps linkage with the z-axis of the main shaft and the x/y on the worktable during machining. , so that each machining point is kept perpendicular to the spindle, forming a machining state like the machining plane of the three-axis machining center.

In this way, the processed surface is smoother.Unlike processing such complex parts with a three-axis machining center, the position that is infinitely close to the actual theoretical surface is used, rather than the designed surface that can be completely processed.

As a result, the machining accuracy cannot meet the design requirements at all.

The same goes for quads.

However, during the machining process, there are much fewer residues than those produced by the three-axis machining center, and the machined trajectory is closer to the designed theoretical shape.The five-axis machining center also cannot fully realize the overlap between the machining trajectory and the theoretical design trajectory.

Not because of anything else, but because of the most central point of the ball end milling cutter for these curved surface milling and finishing processes during the machining process of the machining center.That is to say, the linear velocity of the theoretical processing point is infinitely close to zero...

This is doomed to fail to fully meet the requirements of theoretical design.

"The five-axis and five-linkage machining center of Deke Company in Germany has a quotation of 600 million yuan, and we can't talk about it..." Yun Fei seldom cares about Xin Kaixing's affairs, and Wang Qingfeng is also very busy when he has nothing to do. Don't bother Yunfei.I won't bother Xin Kaixing with these trivial matters.

But the five-axis machining center is what Xinkaixing needs most.

The small five-axis woodworking machines that can be easily bought in China are not only expensive, but the precision is not very high.

"So expensive?" Yun Fei frowned.

The five-axis linkage machining center researched by Jiuyi Research Institute initially estimated that the market price is between 800 million and 200 million, and the production cost is less than 500 million, mainly due to research and development costs and technology costs.

Even if the costs abroad are high, they cannot be too high.

These grandchildren are so ruthless!

But think about it, who told China not to produce it?

Once the five-axis of Jiuyi Heavy Industry appears on the market, their price reduction is predictable.And it's not like other industries cut prices bit by bit. Once Jiuyi Heavy Industry's technical parameters and performance are not as much as foreign products, their price cuts will be in the tens of millions.

Moreover, in the international market, although these devices will not be much higher than domestic ones, the price is still very impressive.This is also the reason why a large number of high-precision and complex parts are processed abroad and thrown to Chinese foundries for processing.

A piece of equipment costs tens of millions, even if it can be used for 30 years, the cost of equipment will cost hundreds of thousands a year. In addition, the labor is much higher than that in China. Even if the price is high, there will not be much profit.

China's cheap labor costs make domestic processing costs only one-third to three-fifths of those abroad.Of course, the processing cost of some imported top-level equipment is much higher than that of foreign countries.However, these equipment are all used by Chinese military enterprises, and they will not accept foreign processing orders at all.

"Not only is it expensive, but the quality is not as high as what they export to the United States and what they use in Europe. The price given to us is nearly 120 million US dollars higher than the price in the European and American markets..." Purchasing Dirk's five-axis five-axis Linkage machining center, this is a strategic plan that has been set a few years ago.However, the equipment procurement cost of Yunfei's budget is only between 600 million and 4000 million.

According to this price, even if it is bought back, Xin Kaixing will suffer a huge loss on this.

The processing cost of a five-axis five-linkage machining center is about [-] to [-] per hour. Even if it does not stop for [-] hours without any accidents, regardless of various costs, the annual profit is only tens of millions.But this is in the case of full business.

On average, it is not bad to have a profit of 600 million a year.

Forty-six million, it will take seven years to fully recover the cost of the equipment. At that time, the accuracy of the equipment has declined.Had to replace it with a new one again...

This is equivalent to working for someone who sells equipment.

What would Yunkai do for such a thing?

There is an unwritten rule in the machining industry, that is, the CNC machining center must earn back the equipment payment within two to three years, otherwise it will be considered a loss.The CNC equipment that Xin Kaixing obtained from Jiuyi Heavy Industry is basically based on this principle.

It took less than two years to earn back the money for the equipment, otherwise it would not have been possible to develop so rapidly.

"Then don't buy it. After a while, wait until the quality of the five-axis machining centers at the research institute stabilizes. Get two of them first." Yun Fei gritted his teeth and said.

Let's conduct a production test when producing these five-axis machining centers that have not yet been fully finalized.

"Where did you get these copying milling machines here? Isn't this a waste of money!" Seeing that there are more than a dozen signs in the machining workshop where the rough machining area is marked with signs because the equipment is not in place! Yun Kai immediately frowned when he saw the copy milling machine.

This guy Wang Qingfeng has committed the problem of collecting second-hand equipment from state-owned factories again!

"It's used for roughing. This is a batch of equipment that can't be sold in the capital. It's [-]. "Wang Qingfeng is very proud.

"I'll go..." Yun Fei wanted to kick him to death.

The production accuracy of Xinkaixing's first batch of three-axis machining centers has begun to decline. Isn't it appropriate to use them here?

This grandson has not changed the problem he left behind when he was in the state-owned factory, the cost of using ordinary machining equipment is lower than that of CNC equipment...

"It's okay. This one is only used for rough machining. The batch of Youjia machining centers replaced by Huadu is used for semi-finishing and four-axis finishing..." Wang Qingfeng saw Yun Fei's expression turned pale, and immediately explained awkwardly.

Although the price of these copying milling machines requires ten sets to catch up with one machining center, the labor is far more than ten times higher than that of a machining center. Compared with those who only need a junior high school education and are not fools, skilled workers on ordinary milling machines The salary of the operator of the machining center that can operate the machine is twice as expensive!And this efficiency is incomparable.

"You said you let me tell you what's good about you? Old Wang. We can't just rely on this benefit when we engage in processing. As the domestic CNC machine tool market becomes more and more competitive, the price is getting lower and lower, and the technical performance It is getting better and better. More people are entering this industry, and we are about to enter an era of meager profits. If we do not effectively control labor costs and improve production efficiency, how will we deal with it when there is no profit?" Yun Fei did not scold Wang Qingfeng, but It was with earnestness and sincerity that he said to him.

It's like he is an old man, and Wang Qingfeng is a young man who doesn't understand anything.

This is not the first time such a scene has appeared. Yun Fei doesn't think it's strange, neither do the people around him, even the people he taught him don't think it's strange.

This is a strange thing.

Therefore, even though Li Lu was almost ten years older than him, when the two were together, Li Lu didn't have to have any pressure because she was so much older than Yun Fei.

It can be said that Wang Qingfeng is the biggest contributor to Yunfei's success today.

Back then, if Wang Qingfeng hadn’t given this 17-year-old young man absolute rights, Yunfei would never have hooked up with the military anyway, and proposed that the three-axis machining center should be equipped with a rotary table driven by a PMC control module to form a simple four-axis machine. The processing center has solved the biggest problem of the military, thus step by step into the sight of the high-level, and then attracted the old man to visit Huashu and Xin Kaixing.

It was at that time that the old man gradually began to favor this young man who was still a child, thinking that he was the future of CNC machine tools in China.

Indeed, Yunkai did not disappoint the old man.

The country has invested billions of dollars in CNC machine tools that have not achieved any results for more than ten years. In just a few years, this kid gave those national scientific research institutes and some large state-owned machine tool factories that have been in business for more than ten years and almost 20 years. Far away, the leaders of those state-owned factories who had been severely slapped in the face by him had to make up their minds to invest in research and catch up.

This is what any country leader would love to see.

If a country wants to ensure security, it must have strong manufacturing capabilities and R&D capabilities. China has become the world's factory with huge manufacturing capabilities, but it simply cannot do it in terms of high-precision cutting-edge industries and scientific research and technology.

China is a big manufacturing country, but definitely not a manufacturing powerhouse.

To become a manufacturing powerhouse, it must have huge technological strength in cutting-edge fields.

Machine tools are the mother of industry.

And CNC machine tools are the most typical representatives of machine tools. To develop this industry, the entire industrial system must develop in a coordinated manner.Materials, technology, manufacturing, design, equipment, electronics, electricity, hydraulics and pneumatics, automatic control, etc., are all ineffective.

"The size of the warehouse is still a bit small, let's get some shelves. Since we want to become a professional impeller factory, we must take a long-term view. The layout must be grand, not too petty..." There are many production processes of impellers, and the processing period is very short. Long, there must be a large enough site to place the semi-finished products of each process.

This is a technology-intensive factory.

According to the current investment scale, even if the researchers are included in the entire factory, the number of people will not exceed 100, and there are only more than [-] front-line production workers.

Most are highly educated technical researchers.

In Yunfei's plan, undergraduates can only be apprentices, graduate students can barely be technicians, and only those with a doctoral degree or above can be researchers...
