"The master should be here. "Deng Lanqing was not too clear about Sun Lin's whereabouts. When the old man came here, Sun Lin and the others knew about it.

Logically speaking, he should be waiting for the old man here. The five-axis was successfully studied, and this honor should be obtained by them. This is why Deng Lanqing has never introduced the parameters of the most important five-axis machining center of the institute.

"Ask them where Mr. Sun went." Yun Fei's face became a little bad. No one could say about this. As the head of the research institute, he is also the main person in charge of the research of the five-axis linkage machining center.

He knew that the old man would come to the research institute this morning, but he didn't show up.

Is there anything more important than reporting to the old man?

At least in Yunfei's opinion, there is no important project in the institute that is about to achieve breakthrough progress.

"Isn't Sun Lin here?" The old man naturally knew some important figures from the Jiuyi Research Institute. It can be said that if Sun Lin and Situ He Yun had not come out of the National Institute of Mechanical Engineering and the Institute of Automation.

It is impossible for this group of old men to make such rapid research progress.

Of course, without some tips from the young man Yun Fei and large-scale research funding, it would be impossible to make such rapid progress.

These technologies cannot be controlled by the country, and many people are very dissatisfied. Without Sun Lin and Situ He Yun, who were originally academicians of the National Academy of Sciences, the Jiuyi Institute would not be able to be allowed to be allowed by the state as it is now

in spite of.

"Only, Mr. Sun has been here for a while. At present, our research institute is conducting research on related fields such as five-axis grinding machines. As the director of the research institute, he is also the person in charge of five-axis,

Of course, Mr. Sun could not put down his burden." Yun Fei saw Deng Lanqing looking for someone to inquire about Sun Lin's whereabouts and took over the old man's topic.

"The master is in the test workshop next to him." Deng Lanqing breathed a sigh of relief after knowing Sun Lin's whereabouts.

"Test workshop? I said, I always feel that there is something missing after the territory of your research institute has expanded." The old man always felt that something missing at Yunfei's research institute.

When I first came, the institute only had one building, which was also carrying out many projects and also had many equipment running on site. The whole environment was very messy. Now, these tens of thousands of square meters are

In the area, only those machine tools for testing are running, and there is no such thing as debugging machine tools.

Only then did I realize that the test workshop and the research project were separated.

"Old man. The research on the five-axis machining center here is all theoretical and systematic research. The five-axis is integrated in the workshop next to it. Let's go there to see how?" The test workshop, there is Yun Fei's preparation.

Gift to the old man.

Of course, only by seeing the processing process of the five-axis machine tool can we deeply understand the functions of the five-axis machine tool.

The old man didn't say anything and nodded.

Deng Lanqing led everyone to the gate several meters wide, introducing the situation: "The function of the five-axis CNC machine tool we have developed is no different from that of the same type abroad. The difference lies in the accuracy.

The problem. The theoretical accuracy is 0.012mm, and the accuracy of 0,018mm can be reached during the actual processing process, which is a big gap compared with the top foreign machining centers. Even the actual processing accuracy of 0,005mm...

”

If there is a gap, you must admit that only in this way can you catch up.

No one can do anything like this. China's CNC machine tools have always been exploring themselves. The domestic mechanical and electronic foundation is not very good, and it started very late. It is also considered to be able to achieve such results now.

Not bad.

"The difference between this and abroad is not that big!" The old man didn't know how precise this data is, but such a small data is only a few percent different, so he praised Yun Fei very satisfied.

Such data is completely high-end for people who don’t understand it. After all, people who are not professionals often come into contact with the most precise ones, which are counted by a few percent, or even a few thousandths of a millimeter.

Counting and thinking about it is very precise.

"Old man, this cannot be compared like this. Our equipment exported to us is more accurate and has stronger functions. That is, the products they exported to us are the lowest-end.

In terms of product situation, the five-axis machining centers exported to our China, whether in Japan, the United States or Europe, can basically only be used for rough processing. Toshiba purchased by the First Aviation Hospital and the Third Aviation Hospital.

And Mitsubishi Heavy Industries' five-axis CNC machine tool, the performance is basically the accuracy level of the equipment used in the 1980s…” Yun Fei did not expect that the old man, who has always been a pity for words, gave such an evaluation.

I couldn't help but smile bitterly.

China's leading position does not mean that it has reached the world's first-class level.

"Oh? Is there a big gap here?" The old man really didn't think of this problem.

"The gap is not only big, but also very big. In precision machining, it is not easy to improve the performance accuracy of processing equipment even if it is one thousandth. It is because they can reach that level abroad.

Industrialization was completed early, and it had a very deep foundation in machinery, electronics and a series of related things. Spain, Italy, and even France, because the foundation in this regard was not as good as the United States, Japan and Germany, so it has always been

It can produce a third-rate garbage machine tool for rough processing..." Yun Fei also wanted to reach the top level abroad in an instant.

Such a thing can only be thought about.

Technology is nothing else, it takes time to accumulate slowly.

However, the current achievement of Jiuyi Research Institute is enough to be proud of the domestic CNC industry.

"So that's it? If you follow your current investment and progress, when will you be able to reach the advanced level abroad?" The old man nodded in praise and asked Yun Fei. Anyone, especially the leader, wishes more international appearances in China.

The leading thing.

This is the foundation of a country. If you fall behind, you will be beaten. This is something that all Chinese people know. Otherwise, if China has been humiliated by the great powers for a hundred years, it will be in vain. Even if it is received by others, no one will be allowed to do so.

Will care.

Just like Ah San, they were originally part of the Empire of Sun Never Setting, so they didn't care at all.

"According to the current research progress, if domestic materials and talent reserves can keep up, the basic research field can also catch up. Within ten years, we can narrow the gap with the top foreign level. It may reach it in the next twenty years.

Their level, perhaps, in fifty years, can surpass them." Yun Fei said very conservatively.

CNC machine tools are a reflection of a country's comprehensive national strength and cannot be supported by a company.

Jiuyi Research Institute is currently able to obtain such research progress, and many of them rely on many companies with good relationships with them, such as 132 Factory, Northern Heavy Industry, Har Heavy Industry, Erzhong, Dongqi Group, etc., in various fields.

Technical support for state-owned enterprises at the top level in China.

In China, the Jiuyi Research Institute can be said to be the best in the first place, but Yunshi Holdings has no advantages in basic materials, precision machinery manufacturing, equipment solutions, etc. Especially in the material sector, it is serious.

Constrain the performance of their equipment.

These companies that have a good relationship with Jiuyi Group all have their own material factories and are also part of the National Materials Research Institute. Many technologies can be obtained through these companies to obtain the most advanced military material technology owned by the country. In this regard, the cloud

Not all of them are undeniable. Jiuyi Materials does not study basic materials, but special materials that also belong to the military field and the top tool materials in the civilian field.

After catching up with foreign countries, Yun Fei can only say that it is possible in twenty years.

China is developing, and abroad will also develop.

In the early stages, as long as the country's comprehensive strength keeps up, it will be very fast, but the later it will be slower. Just like the aerospace technology of humans on Earth, the former Soviet Union was in the 1970s.

The International Space Station has been established. The Americans said at the beginning that they had landed on the moon. Unfortunately, these space technologies have not made much progress. Mir is about to retire and no country is ready to build a new space station.

The Americans have landed on the moon decades ago. In so many years, they have never landed again. They have established a lunar base and turned the moon, a resource-rich satellite into fifty-two Americans who have always had expansion ambitions.

Will Americans have no idea about something like state?

It’s not that Americans don’t want to, but that Americans don’t have the ability to do such things at all! The photos of Americans landing on the moon were fake! If Americans really had such technology, they would definitely build a better than Russians.

A more awesome space station, rather than using the Russian space station to conduct their experiments.

Aerospace technology is something that all countries are vigorously studying. Americans spend tens of billions or hundreds of billions of dollars on it every year. Even when Yun Fei left his original world, he never landed on the moon again.

The numerous space shuttles have no new production plans after they are retired... (To be continued...)
