Chapter 772

Guocheng impeller factory is the first professional impeller manufacturer in China. Although the construction has just been completed, it has not been officially put into operation, and even trial production has not started. Steam turbine manufacturers such as Harbin steam turbine and Dongfang Steam Turbine have always relied on imported Chinese manufacturers, and have long looked forward to a professional impeller manufacturer in China.

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

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 fills the gap of domestic high-end equipment in the domestic market. In the machining of complex three-dimensional surfaces such as impeller, it not only improves the efficiency, but also effectively reduces the production cost.

Of course, four axis machining center processing impeller, processing is still relatively reluctantly.

"When will the five axes of the 91 Research Institute be ready? The four-axis machining center is still reluctant to produce these distorted three-dimensional surfaces... "Yun Fei didn't bother to go there because the laboratory was not built well.

Moreover, now they are doing some simple physical and chemical analysis, impact and tensile tests on the materials, and the testing methods for the processed finished products are not complete. Even if he went to the laboratory, he just looked at the flowers and couldn't see anything. He had seen too much of the materials on September 1.

Just a few people went to the machining workshop.

This is an industry where Yunfei started. At present, although its scale in this industry is small, it is recognized as the first in the whole country with strong processing technology strength, complete processing equipment and accurate processing technology.

At present, even in some large old state-owned factories, the processing of many new products is lost to xinkaixing. Most of the parts of state-owned military factories that have not completed the upgrading of technical equipment are also handed over to xinkaixing for processing.

Moreover, the means and accuracy of machining complement and promote each other with the CNC machine tools produced by Jiuyi heavy industry. 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 means. It is basically a model factory for large-scale processing and display of 91 heavy industry and Northern heavy industry.

The selection of processing mode, the provisions on the scope of use of processing equipment, the selection of various parameters and staffing are the most advanced in the whole of China, because Yunfei proposed from the beginning that we must seek benefits from management and profits from management.

The management cost of xinkaixing is indeed very low.

Otherwise, xinkaixing's machining business could not have such a high profit.

"Five axis is indeed the most suitable for the processing of complex group surface parts such as impeller, but the current processing accuracy is still relatively poor, and the NC system has not made much progress. If it is used for the production of complex parts with low precision requirements, there is no problem, but in that case, the cost of the equipment is too high, and some difficult parts are processed, It can only be used for rough machining... "Yun Fei sighed.

The impeller belongs to the processing of spiral twisted three-dimensional curved surface. The processing of the four-axis machining center is mainly based on the rotating fourth axis, that is, the b axis maintains linkage with the Z axis of the main shaft and the XY on the workbench during processing, so that each machining point is maintained perpendicular to the main shaft, forming the processing state of the machining plane of the three-axis machining center.

In this way, the machined surface is relatively smooth. Unlike machining such complex parts with a three-axis machining center, it only uses the position infinitely close to the actual theoretical surface, rather than the designed surface.

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

The same is true for the four axes.

However, the residue in the machining process is much less than that in the three-axis machining center, and the machined trajectory is more close to the designed theoretical shape. The five axis machining center can not completely overlap the machining trajectory with the theoretical design trajectory.

Not because of anything else, just 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 speed of the theoretical machining point is wirelessly close to zero

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

"The five axis and five linkage processing center of Dirk company in Germany offers 460 thousand units, which can't be talked about..." Yun Fei seldom cares about Xin Kaixing. Wang Qingfeng seldom bothers Yun Fei when there is nothing at ordinary times, and won't bother him with Xin Kaixing's trivia.

However, the five axis machining center is what xinkaixing needs most.

At present, those small five axis woodworking machines that can be easily bought in China are expensive and the accuracy is not very high.

"So expensive?" Yun Fei frowned.

The five axis linkage processing center studied by the 91 Research Institute preliminarily estimates that the market price is between 18 million and 22 million, and the production cost is less than 5 million, mainly R & D costs and technology costs.

Those costs abroad, even if high, can not be too high.

These grandsons are too cruel!

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

Once the five axes of Jiuyi heavy industry appear in the market, their price reduction is predictable. Moreover, unlike other industries, the price reduction is reduced bit by bit. Once the technical parameters and performance of 91 heavy industry are not much compared with foreign products, the price reduction will be counted in tens of millions.

Moreover, in the international market, although these equipment will not be much higher than that in China, the price is also very shocking. This is also the reason why foreign countries have a large number of high-precision complex parts to be processed in China's foundry.

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

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

"It's not only expensive, but also the quality can't match their export to the United States and the high quality they use in Europe. The price given to us is nearly $1.2 million higher than the price in the European and American markets... "Purchasing Dirk's five axis five linkage processing center is a strategic plan that has been made a few years ago, but the non budget equipment procurement cost of cloud is only between $36 million and $40 million.

At this price, even if we buy it back, xinkaixing will suffer huge losses.

The processing cost of the five axis five linkage processing center is about 12 to 15 per hour. Even if there is no shutdown for 20 hours, there will be no accident. Regardless of various costs, it will not make a profit of 10 million a year, but this is in the case of full business.

On average, it's good to make a profit of six million a year.

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

This is equivalent to working for people who sell equipment.

Will Yunkai do such a thing?

There is an unwritten rule in the machining industry, that is, the CNC machining center must earn the equipment money within two to three years, otherwise it will be a loss. At present, the CNC equipment obtained by xinkaixing from Jiuyi heavy industry is basically based on this principle.

We can earn the equipment money in less than two years, otherwise it would not develop so rapidly.

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

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

"Where did you get these profiling milling machines here? Isn't this a waste of money? " Yunketon frowned when he saw that there were more than ten profiling milling machines in the machining workshop where the rough machining area was written on the sign because the equipment was not in place.

Wang Qingfeng has made another mistake in collecting second-hand equipment from state-owned factories!

"It's used for rough machining. This is a batch of equipment that can't be sold in the capital, 43000. I asked someone to make trouble and make a set of tooling for rough machining..." Wang Qingfeng was very proud.

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

The production accuracy of the first batch of three-axis machining centers of xinkaixing has begun to decline. Isn't it right to use this side?

The grandson has not changed the problem that the cost of using ordinary machining equipment is lower than that of numerical control equipment when he was in the state-owned factory

"It's all right. This is only used for rough machining. The batch of Youjia machining centers replaced from Huadu are used for semi-fine machining and four-axis fine machining..." Wang Qingfeng explained awkwardly when he saw Yun Fei's face.

Although the price of these profiling milling machines takes ten to catch up with one machining center, the labor is far more than ten times higher than that of the machining center. The wages of the technicians of ordinary milling machines are two times higher than those who only need junior high school education and can operate the machining center where people who are not fools can operate the machine! And this efficiency is unmatched.

"What do you want me to say about you? Lao Wang, we are engaged in processing. We can't just rely on our immediate interests. With the increasingly fierce competition in the domestic CNC machine tool market, lower and lower prices and better technical performance, more and more people enter this industry. We are about to enter an era of low profits. If we do not effectively control labor costs and improve production efficiency, how can we deal with it when there is no profit? " Yun Fei didn't scold Wang Qingfeng, but said to him in earnest.

Just as he is an old man, Wang Qingfeng is a young man who knows nothing.

This scene is not the first time. Yun Fei doesn't feel strange, the people around him don't feel strange, and even the people he taught don't feel strange.

This is a strange thing.

Therefore, even if Li Lu is ten years older than him in age, when they are together, Li Lu has no pressure because she is so much older than Yunfei.

Cloud can not have today, it can be said that Wang Qingfeng is the greatest hero.

If Wang Qingfeng had not given this 17-year-old young man absolute rights, Yun Fei could not have hooked up with the military in any case. He proposed that the three-axis machining center should be equipped with a rotary workbench driven by PMC control module to form a simple four-axis machining center, which solved the biggest problem of the military and stepped into the sight of the high-level step by step, Then attract the old man to visit the number of flowers and xinkaixing.

It was at that time that the old man gradually began to favor the young man who was still a child and thought he was the future of the whole Chinese CNC machine tool.

Indeed, Yunkai didn't let the old man down.

The state has invested billions in CNC machine tools that have not achieved much in more than ten years. In just a few years, this boy has thrown away the national scientific research institutes and some large state-owned machine tool factories that have been engaged in more than ten years and nearly 20 years, so that the leaders of the state-owned factories who have been severely beaten by him have to devote themselves to research and catch up.

This is what leaders of any country are willing to see.

If a country wants to ensure safety, it must have strong manufacturing capacity and R & D capacity. China has become a world factory with huge manufacturing capacity, but it can't do in high-precision and cutting-edge industries and scientific research and technology.

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

To become a manufacturing power, we must have huge technical 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 whole industrial system must develop harmoniously. Materials, technology, manufacturing, design, equipment, electronics, electrical, hydraulic and pneumatic, automatic control and other fields, but they are not the same.

"The scale of the warehouse is still a little 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 atmospheric, not too small... "There are many production processes of the impeller, and the processing period is very 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, the number of researchers in the whole factory will not exceed 400, and there are only more than 100 front-line production workers.

Most of them are highly educated technical researchers.

In Yunfei's plan, undergraduates can only be apprentices, postgraduates can barely be technicians, and only those with a doctor's degree or above can be researchers
