"The master should be in here." Regarding Sun Lin's whereabouts, Deng Lanqing is not too clear. When the old man came here, Sun Lin and the elders all knew.

It stands to reason that he should be waiting for the old man here. The five axes were successful in their research, and this honor should also be given to them. This is why Deng Lanqing has not introduced the parameters of the most important five-axis machining center of the institute.

"Ask them where Elder Sun has gone." Yun Fei's face became a little unpleasant. As the person in charge of the research institute and the main person in charge of the research of the five-axis linkage machining center, he knew that the old man would go to the research institute this morning, but he did not appear.

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

At least in Yun Fei's opinion, no. None of the major projects in the institute are about to make a breakthrough.

"Isn't Sun Lin here?" For some important people in the Jiuyi Research Institute, the old man naturally knows. It can be said that if it were not for Sun Lin and Situ Heyun, a group of old men who came out of the National Academy of Mechanical Sciences and the Institute of Automation, it would be impossible to achieve such rapid research progress.

Of course, without some tips from Yun Fei, a young man, and large-scale research funding, it would not have been possible to make such rapid progress.

These technologies cannot be controlled in the hands of the state, and there are many people who are very dissatisfied, and if there are no Sun Lin and Situ Heyun, who originally belonged to the academicians of the National Academy of Sciences, the Jiuyi Research Institute will not be able to be left alone by the state as it is now.

"Yes. Old man, Sun Lao has been here for this time, at present, our research institute is carrying out research in related fields such as five-axis grinders, as the president of the research institute, and also the person in charge of the five-axis, Sun Lao naturally can't put down the burden. Yun Fei saw that Deng Lanqing was looking for someone to inquire about Sun Lin's whereabouts, and took over the topic of the old man.

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

"Test workshop? I'll just say that I always feel that after the expansion of your research institute's territory, something is missing. "The old man has always felt that Yun Fei's scene in this research institute is missing something.

When I first came here, the institute was only one building, and there were many projects being carried out at the same time, and at the same time, a lot of equipment was running on site, and the whole environment was very messy. And now in this area of tens of thousands of square meters, only those machine tools for testing are running, and there are no debugging machine tools or anything at all.

Only then did I realize that the test workshop was separated from the research project.

"Old man. The research of the five-axis machining center here is some theoretical research and systematic research, and the five-axis is integrated in the workshop next to it. "The test workshop, there is a gift that Yun Fei is going to give to the old man.

Of course, only in it, seeing the machining process of the five-axis machine tool, can we deeply understand the function of the five-axis machine tool.

The old man did not speak, but nodded.

Deng Lanqing led everyone towards the gate several meters wide next to him, and introduced the situation: "The five-axis CNC machine tool we have researched at present. The function is no different from the same type abroad, and the difference lies in the accuracy. The theoretical accuracy is 0.012mm, and the accuracy can reach 0.018mm in the actual machining process, which is less than the level of 0.01mm than the top foreign machining centers. There is a big gap in the actual machining accuracy even within 0,005 mm......"

If there is a gap, we must admit it, and only in this way can we catch up.

No one can do anything about such a thing. China's CNC machine tools have always relied on their own exploration, and the domestic mechanical and electronic foundation is not very good, and the start is also very late. It's good to be able to have such results now.

"This is not much different from foreign countries!" The old man didn't know how precise this number jù was, but such a small number jù only had a difference of a few percent, so he praised Yun Fei with satisfaction.

Such a number is completely lofty for those who don't understand. After all, people who are not professionals often come into contact with the most precise millimeters, counting in hundredths, or even thousandths of millimeters, thinking about it is very precise.

"Old man, this can't be compared like this. Compared with the equipment exported to us abroad, the accuracy is higher, and the function is stronger, that is, when the products they export to our country are the lowest-end products. The five-axis machining centers that the Japanese exported to our China, whether in Japan, the United States or Europe, can basically only be used for rough machining. The five-axis CNC machine tools of Toshiba and Mitsubishi Heavy Industries purchased by the First Aviation Institute and the Third Aviation Institute are basically the accuracy level of those equipment used in the eighties abroad...... "Yun Fei didn't expect that the old man who has always cherished words like gold would give such an evaluation, and he couldn't help but smile bitterly.

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

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

"The gap is not just big, it's very big. In precision machining, it is not easy to improve the performance accuracy of processing equipment even if you want to improve it by one thousandth. Foreign countries can achieve that kind of process because they completed industrialization early, and they have a very deep foundation in mechanics, electronics, and a series of related things. Spain, Italy, and even France, these countries are not as good as the United States, Japan and Germany because their foundation in this regard is not as good as that of the United States, Japan and Germany, so they have only been able to produce third-rate garbage machine tools for rough processing...... "Yun Fei also wants to reach the top level abroad at once."

Such a thing can only be thought about.

Technology is nothing else, it takes time to build up.

However, Jiuyi Research Institute can currently have such achievements, which is enough for Yunfei to be proud of the domestic CNC industry.

"I see? If you follow your current investment and progress, when will you be able to reach the advanced level abroad? The old man nodded approvingly and asked Yun Fei. Anyone, especially leaders, wishes that there would be more international leadership at home.

This is the foundation of a country, and if you are backward, you will be beaten, and this is something that all Chinese know. Otherwise, if China suffers a hundred years of humiliation by the great powers, it will really be in vain, and no one will care even if it suffers again.

Just like Ah San, people originally belonged to a part of the empire on which the sun never set, and they didn't care at all.

"According to the current research progress, if the domestic materials and talent pool can keep up, and the basic research field can also catch up, within ten years, we can close the gap with the top level abroad. It is possible to reach their level in the next twenty years, and perhaps, fifty years later, to surpass them. Yun Fei said very conservatively.

CNC machine tools are the embodiment of a country's comprehensive national strength, and it is not something that a company can support.

At present, Jiuyi Research Institute has been able to obtain such research progress, and many of them rely on the technical support of many enterprises that have a good relationship with them, such as 132 Factory, North Heavy Industry, Haer Heavy Industry, Erzhong, Dongqi Group, etc., which are all state-owned enterprises that belong to the top level of domestic counterparts in various fields.

In China, Jiuyi Research Institute can be said to be the first, but in terms of basic materials, precision machinery manufacturing, equipment solutions, etc., Yunshi Holdings has no advantages at all. In particular, the material strictly restricts the performance of their equipment.

These enterprises that have a good relationship with Jiuyi Group have their own material factories and are also part of the National Materials Research Institute. This is undeniable. Jiuyi materials are not basic materials, but special materials that also belong to the military field and the top tool materials in the civilian field.

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

China is developing, and so will foreign countries.

In the early stage, as long as the country's comprehensive strength keeps up, it will be very fast, but the later it will be, the slower it will be. Just like the aerospace technology of human beings on the earth, the former Soviet Union has built the International Space Station in the 70s, and the Americans also said that they have landed on the moon, but unfortunately, these space technologies have not made much progress now. Mir is nearing retirement, and no country is ready to build a new space station.

And the Americans, who landed on the moon decades ago, have never landed again for so many years, to build a lunar base, to turn the moon, a resource-rich satellite, into fifty-two states of the United States that have always had expansionist ambitions, and such a thing as the Americans will not have ideas?

It's not that Americans don't want to, it's that Americans simply don't have the ability to do such a thing! The photos of the Americans landing on the moon back then were fake! If the Americans really have such technology, they will definitely build a space station that is even more powerful than Lao Maozi, instead of using Lao Maozi's space station to conduct their experiments.

Space technology is something that all countries are vigorously researching, and the Americans throw tens of billions of dollars into it every year, and even when Yun Fei left his original world, he never landed on the moon again. And the large number of space shuttles did not have new production plans after they were decommissioned...... (To be continued......)
