The Guocheng Impeller Plant is the first professional impeller manufacturer in China. Although the construction has just begun and it has not yet been officially put into operation, even trial production has not yet begun. These impellers of turbine manufacturers such as Harbin Steam Turbine and Dongqi It has always been a Chinese manufacturer that relies on imports, and it has long been hoped that a professional impeller manufacturer will be able to support it in China.

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 processing and forming for each process.

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

This requires very high processing 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, four-axis machining center processing impeller is still relatively reluctant to process.

"When can the five-axis on the Jiuyi Research Institute be built? The four-axis machining center is still a bit reluctant to produce these distorted three-dimensional surfaces..." The laboratory was not built, and Yun Fei didn't bother to look there.

Moreover, some simple physical and chemical analysis and impact and tensile tests are done on materials now, and the inspection methods for processed finished products are not complete.Even if he went to the laboratory, he was just looking at the flowers and couldn't see anything. He had already read too much in the materials on September 1st.

A few people simply went to the machining workshop.

This is the industry that Yunfei started. Although his current scale in this industry is not large, his processing technology strength, complete processing equipment, and precision processing technology are recognized as the first 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 machining methods and precision are complementary to and mutually reinforcing with the CNC machine tools produced by Jiuyi Heavy Industries.As long as Jiuyi Heavy Industry produces any new products, the first user is Xinkaixing.

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

The choice of processing mode, the regulations on 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 from the very beginning, Yunfei proposed that it is necessary to seek benefits from management, Want profit.

And Xinkaixing's management cost is indeed very low.

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

"The five-axis is indeed the most suitable for the processing of complex surface parts such as impellers, but the current processing 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 that require less precision , There is no problem, but in that case, the cost of this equipment will be too high. When encountering some difficult parts, it can only be used for roughing (rough machining)..." Yun Fei sighed.

Impellers belong to the processing of spirally twisted three-dimensional curved surfaces. The processing of the four-axis machining center mainly relies on the fourth axis of rotation, that is, the B-axis maintains linkage with the spindle Z axis and the XY on the worktable during processing. Each processing point is kept perpendicular to the spindle, forming a processing state like the processing plane of a three-axis machining center.

In this way, the processed surface is relatively smooth, unlike the use of a three-axis machining center to process such complex parts, it only uses a position that is infinitely close to the actual theoretical surface, rather than the design that can be processed. Strip surface.

In this way, the machining accuracy will not meet the design requirements.

The same is true for the four axis.

However, in the machining process, there are much fewer residues than the three-axis machining center, and the processed trajectory is closer to the theoretical shape of the design.The five-axis machining center also cannot fully overlap the machining track with the theoretical design track.

Not because of anything else, but because in the machining process of the machining center, the most central point of the ball-end milling cutter for surface milling and finishing, that is, the linear velocity of the theoretical machining point is wirelessly approaching zero...

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

"The five-axis and five-linked machining center of Dirk in Germany is quoting 46 million units, so I can't talk about it..." Yun Fei rarely cares about Xin Kaixing, and Wang Qingfeng usually has nothing to do. I rarely bother Yun Fei and don't bother him with these trivial things about Xin Kaixing.

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 expensive and the accuracy is not very high.

"So expensive?" Yun Fei frowned.

The five-axis machining center researched by the Jiuyi Research Institute is initially estimated to be priced between 18 million and 22 million, and the production cost is less than 5 million, mainly research and development costs and technical costs.

Even if the costs in foreign countries are high, they cannot be too high.

These grandchildren are too cruel!

But think about it, why can't China produce it?

Once the five-axis of Jiuyi Heavy Industry appears on the market, their price cuts are foreseeable.And it’s not like the price cuts in other industries are dropping little by little. Once the technical parameters and performance of Jiuyi Heavy Industry are not as large as those of foreign products, the extent of their price cuts will be tens of millions.

Moreover, in the international market, although these devices are not much higher than the domestic ones, the prices are also very staggering.This is also the reason why foreign countries have large quantities of high-precision and complex parts to be processed by Chinese foundries.

A piece of equipment is tens of millions. Even if it can be used for 30 years, it will cost hundreds of thousands of equipment a year. In addition, the labor is much higher than that in China. Even if the price is high, it will not make 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 equipment is much higher than that of foreign countries.However, these equipments are all used in Chinese military enterprises and will not accept foreign processing orders at all.

"Not only is it expensive, but the quality is not as high as they can be exported to the United States and used in Europe. The price given to us is nearly 1.2 million US dollars higher than the price in the European and American markets..." The five-axis five-linked machining center is a strategic plan that was laid down a few years ago, but Yunfei’s equipment procurement costs are only between 36 million and 40 million.

At this price, Xinkaixing will suffer a huge loss even if it is bought back.

The processing cost of a five-axis five-linked machining center is about 1200 to 1500 per hour. Even if there is no shutdown for 20 hours, there will be no accidents. Aside from various costs, it is not more than 10 million profits a year, but This is in the case of full business.

On average, a profit of six million a year is good enough.

Forty-six million yuan, it will take seven years to fully earn back the cost of the equipment. At that time, the accuracy of the equipment has dropped and new equipment must be replaced again...

This is equivalent to working for the person selling the equipment.

What would Yun Kai do with such a thing?

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

It takes less than two years to earn money back for the equipment, otherwise it would not be possible to develop so quickly.

"Then don't buy it. After a while, when the quality of the five-axis machining center at the research institute stabilizes, get two of them first." Yun Fei gritted his teeth.

Just produce these five-axis machining centers that have not been fully finalized for production trials.

"Where did you get these profiling milling machines from here? Isn't it a waste of money!" Seeing that there are more than ten places in the machining workshop that is empty because the equipment is not in place and the roughing area is written on the sign. With the profiling milling machine, Yun Kai frowned.

Wang Qingfeng has committed another problem with collecting second-hand equipment from state-owned factories!

"It's used for roughing. This is a batch of unsold equipment from Capital No. 1 Machine. It is forty-three thousand and one. I asked someone to make a mess, and I made a set of tooling and used it for rough processing.... "Wang Qingfeng was very proud.

"I'm going..." Yun Fei couldn't wait 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 it here?

This grandson has not yet changed the problem that he left behind when he was in a state-owned factory that using ordinary machining equipment cost less than numerical control equipment...

"It's okay. This is just for rough machining. The batch of Youjia machining centers that were replaced in Huadu are used for semi-finishing and four-axis finishing..." Wang Qingfeng saw Yun Fei's face edged, suddenly Explained embarrassingly.

Although the price of these profiling milling machines can catch up with a machining center by ten sets, the labor is far more than ten times higher than that of a machining center. The skilled workers of ordinary milling machines are more expensive than those who only need junior high school education and are not fools. The wages of operators in machining centers who can operate machines are twice as expensive!And this efficiency is incomparable.

"You said you let me say what is good about you? Lao Wang, we can't just rely on this point of interest when we do processing. As the domestic CNC machine tool market becomes more and more competitive, prices are getting lower and lower, and technical performance It is getting better and better. More people enter this industry. We are about to enter an era of meager profit. If we do not effectively control labor costs, improve production efficiency, and there is no profit, how do we respond?" Yun Fei did not scold Wang Qingfeng, and It was Yu Zhongxin said to him.

It was as if he was an old man, and Wang Qingfeng was a young man who knew nothing.

It was not the first time that such a scene appeared. Yun Fei didn't think it was weird. The people around him didn't think it was weird.

This is a strange thing.

Therefore, even if Li Lu was almost ten years older than him, when the two were together, Li Lu did not absolutely have any pressure because he was so much older than Yun Fei.

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

Had it not been for Wang Qingfeng to give this 17-year-old young man absolute rights, Yun Fei would not have been able to hook up with the military anyway, and proposed that the three-axis machining center was equipped with a rotary table driven by a PMC control module to form a simple four The shaft machining center solved the biggest problem of the military, and step by step entered the high-level sight, and then attracted the old man to visit Huashu and Xinkaixing.

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 CNC machine tools in China.

Indeed, Yun Kai did not disappoint the old man.

The country has invested hundreds of millions of dollars in CNC machine tools that have not achieved any results for more than a decade. In just a few years, this kid has taken the national scientific research institutes and some large state-owned machine tool factories that have been engaged for more than ten or twenty years. Throwing away from a distance, the leaders of the state-owned factories that were smashed by him had no choice but to devote themselves to research and catch up.

This is what any country 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 its manufacturing capabilities are huge. However, in high-precision and cutting-edge industries, as well as scientific research and technology, it is simply not possible.

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

If you want to become a manufacturing powerhouse, you must have huge technical strength in the cutting-edge field.

Machine tools are the mother of industry.

And CNC machine tools are the most typical representative of machine tools. To develop this industry, the entire industrial system must develop in a coordinated manner.Materials, technology, manufacturing, design, equipment, electronics, electrical, hydraulics and pneumatics, automatic control, etc., but the same is not good.

"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 for impellers, and the processing time is very long. Long, it must have a large enough site to place the semi-finished products of each process.

This is a technology-intensive factory.

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

Most of them are highly educated technical researchers.

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