Guocheng Impeller Factory, is the first professional impeller production plant in China, although the construction has just begun, has not been officially put into production, even the trial production has not begun, Harbin Automobile, Dongqi and other steam turbine production plants These impellers have been relying on imported Chinese manufacturers, and have long been looking forward to a professional impeller production plant in China to match.

Impeller not only has high requirements for production materials, but also has higher requirements for processing technology, which is a complex three-dimensional surface processing, and requires each process to be processed and formed once.

It is not one side that is processed and molded at one time, but two sides are processed and formed at one time, and only in this way can the accuracy be guaranteed.

This requires a very high processing accuracy of the equipment.

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

Of course, the four-axis machining center processes the impeller, and the processing is still relatively reluctant.

"When will the five axes over there be a 91 Research Institute? The four-axis machining center is still a little reluctant to produce these distorted three-dimensional surfaces...... "The real room has not been built, and Yun Fei is too lazy to go over there to see."

Moreover, now it is also a simple physical and chemical analysis of materials, impact and tensile tests, and the detection methods of processed finished products are incomplete. Even if he went to the real yàn room, he was just looking at the flowers, and he couldn't see anything, and he had already seen too much in Jiuyi materials.

A few people simply went to the machining workshop.

This is the industry that Yun Fei started, although the scale of his current industry is not large, but the strength of processing technology, the complete processing equipment, and the accuracy of processing technology are recognized as the first in the whole country.

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

And. The means and precision of machining are complementary and mutually reinforcing with the CNC machine tools produced by Jiuyi Heavy Industry. As long as Jiuyi Heavy Industry produces any new products, the first user is Xin Kaixing.

Many domestic machinery companies to visit Xinkaixing, learn their advanced management concepts and processing methods, basically a 91 heavy industry and the north heavy industry of large-scale processing display model factory.

The selection of processing mode, the scope of use of processing equipment, the selection of various parameters, and the staffing are the most advanced in the whole of China, because Yun Fei has proposed it from the beginning. We must ask for benefits from management and profits from management.

The management cost of Xinkaixing is indeed very low.

Otherwise, Xinkaixing's machining business would not have such a high profit.

"The five axes are indeed the most suitable for the processing of these complex group parts of the impeller, but the current machining accuracy is still relatively poor, and the CNC system has not made much progress, if it is used for the production of some complex parts with high accuracy requirements, there is no problem. However, in that case, the cost of this equipment is too high, and when encountering the processing of some difficult parts, it can only be used for rough (rough machining) ......" Yun Fei sighed.

Impellers are the machining of spirally twisted three-dimensional surfaces. The machining of the four-axis machining center mainly relies on the rotating fourth axis, that is, the B-axis, to maintain linkage with the Z-axis of the spindle and the X/Y on the worktable during processing, so that each processing point is perpendicular to the spindle. This results in a machining state like a three-axis machining center machining plane.

As a result, the machined surface is smoother, unlike complex parts that are machined with a three-axis machining center. Only the position of the actual theoretical surface is infinitely close to the actual theoretical surface, not the surface that can be fully machined for the design.

In this way, the machining accuracy does not meet the requirements of the design at all.

The same is true for the four axes.

However, in the machining process, there is much less residue than that of a three-axis machining center, and the trajectory is closer to the theoretical shape of the design. Five-axis machining centers also cannot fully realize the overlap of machining trajectories and theoretical design trajectories.

Not because of anything else, but because in the machining process of the machining center, the linear velocity of the most central point of the ball nose milling cutter for these surface milling finishes, that is, the theoretical machining point, is wirelessly 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 Dirk Company in Germany is quoted at 46 million units, and I can't talk about it...... "Yun Fei rarely cares about Xin Kaixing's affairs, and Wang Qingfeng rarely bothers Yun Fei when he has nothing to do, and he will not bother him with these trivial things of Xin Kaixing."

However, the five-axis machining center is what Xin Kaixing needs the most.

At present, those small five-axis woodworking machines that can be easily bought in China are not only expensive, but also not very accurate.

"So expensive?" Yun Fei frowned.

The five-axis linkage machining center studied by the Jiuyi Research Institute is preliminarily estimated to be priced between 18 million and 22 million, and the production cost is less than 5 million, mainly due to R&D costs and technical costs.

Even if the costs abroad are high, they can't be too high.

These grandsons are so ruthless!

But think about it, who said that China can't produce it?

Once Jiuyi's five-axis appeared on the market, their price reduction was predictable. And unlike other industries, the price reduction is falling little by little, once the technical parameters and performance of Jiuyi Heavy Industry are not much with foreign production, their price reduction will be counted in tens of millions.

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

A piece of equipment tens of millions, even if it can be used for 30 years, it will cost hundreds of thousands of equipment a year, plus the labor is much higher than in China, even if the price is very 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 used in China's military industrial 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 1.2 million US dollars higher than the price in the European and American markets...... "Purchase Dirk's five-axis five-linkage machining center." This is a strategic plan that has been in place for several years, but the cost of purchasing equipment from the cloud is only between 36 million and 40 million.

At this price, even if it is bought back, Xin Kaixing will have a huge loss on it.

The processing cost of the five-axis five-linkage machining center is about 12 to 15000 per hour, even if it does not stop for 20 hours, without any accidents, aside from various costs, it is only 10 million profits a year, but this is in the case of full business.

On average, there are six million profits a year. That's already good.

46 million, it will take seven years to fully recover the cost of the equipment, by that time, the accuracy of the equipment has declined, and the equipment must be replaced with new equipment again......

It's the equivalent of working for someone who sells equipment.

Will Yun Kai do such a thing?

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

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

"Then don't buy it. After a while, when the quality of the five-axis machining center at the research institute is stable, two will be brought out first. Yun Fei gritted his teeth and said.

Let's just produce these five-axis machining centers that have not yet been fully finalized and conduct production tests.

"Where did you get these copy milling machines from? Isn't that a waste of money? Seeing that there were more than a dozen copy milling machines in the machining workshop that seemed empty because the equipment was not in place, there were more than ten copy milling machines in the place where the rough processing area was written on the sign, Yun Kai immediately frowned.

Wang Qingfeng's mistake of collecting second-hand equipment from state-owned factories has been committed again!

"It's used to open a rough mouth. This is a batch of equipment that cannot be sold in the capital, 43,000 one, I found someone to make a set of tooling. There is no problem with rough machining...... "Wang Qingfeng is very proud.

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

The production accuracy of the earliest batch of three-axis machining centers in Xinkaixing has begun to decline, isn't it appropriate to use it here?

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

"It's okay, this one is just for rough machining. The batch of Youjia's machining centers that were replaced by Huadu are used for semi-finishing and four-axis finishing......" Wang Qingfeng saw Yun Fei's face, and immediately explained embarrassedly.

Although the price of these copy milling machines takes ten to catch up with a machining center, the labor is far more than ten times higher than that of the machining center, and the skilled workers of ordinary milling machines are one or two times more expensive than those who only need the initial Chinese process dù and are not stupid people can operate the machine! And this efficiency is also incomparable.

"You say you're going to let me say what is good about you? Lao Wang, we can't just rely on the immediate benefits. With the domestic CNC machine tool market competition is becoming more and more fierce, the price is getting lower and lower, the technical performance is getting better and better, more people are entering this industry, we are about to enter an era of low profits, if we do not effectively control labor costs, improve production efficiency, no profits, how do we respond? Yun Fei did not scold Wang Qingfeng, but said to him seriously.

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

This is not the first time that such a scene has appeared, Yun Fei does not feel strange, the people around him do not feel strange, and even the people who have been taught by him do not feel strange.

That's a strange thing.

Therefore, even if Li Lu is almost ten years older than him in age, when the two are together, Li Lu does not have any pressure because he is so much older than Yun Fei.

Yun Fei can have today, it can be said that Wang Qingfeng is the biggest hero.

If it weren't for Wang Qingfeng giving this young man who was only seventeen years old absolute rights, Yun Fei would not have been able to hook up with the military anyway, and proposed that the three-axis machining center be equipped with a rotary worktable driven by the PMC control module to form a simple four-axis machining center, which solved the biggest problem of the military, so as to step by step into the sight of the high-level, and then attracted the old man to visit the number of flowers and Xin Kaixing.

It was from that time that the old man gradually began to favor this young man who was still a child, and felt that he was the future of the entire Chinese CNC machine tool.

Indeed, Yun Kai did not disappoint the old man.

The state has invested hundreds of millions of CNC machine tools that have not achieved any results for more than 10 years, and this kid has thrown away the national scientific research institutes and some large state-owned machine tool factories that have been engaged in more than 10 years and almost 20 years in just a few years, so that the leaders of the state-owned factories who were slapped in the face by him had to invest ruthlessly in research and catch up.

This is what any national leader would like to see.

If a country wants to ensure safety, it must have strong manufacturing capabilities and R&D capabilities, China has become the world's factory, and the manufacturing capacity is very huge, but in high-precision and cutting-edge industries, as well as scientific research and technology, it is not at all.

China is a manufacturing power, but it is definitely not a manufacturing power.

If you want to become a manufacturing powerhouse, you must have a huge technological strength in cutting-edge fields.

Machine tools are the mother of industry.

CNC machine tools are the most typical representatives of machine tools, in order to develop this industry, the entire industrial system must be coordinated development. Materials, processes, manufacturing, design, equipment, electronics, electrical, hydraulic and pneumatic, automatic control and other fields, but the same.

"The scale 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 has to be atmospheric, not too small...... "There are many production processes of impellers, and the processing period is very long, so there must be a large enough site to place the semi-finished products of each process."

It is a technology-intensive plant.

According to the current scale of investment, the number of researchers in the entire factory will not exceed 400, and the number of front-line production workers is only more than 100.

Most of them are highly educated technical researchers.

In Yunfei's plan, undergraduates can only be apprentices, graduate students can barely become technicians, and only those with a doctorate degree or above can become researchers...... (To be continued......)
