Chapter 1102

"Shifu should be here." Deng Lanqing is not too clear about Sun Lin's whereabouts. The old man came here. Sun Lin and his elders knew it.

Normally, he should be waiting for the old man here. The five axis is their successful research, and this honor should also be won 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 sun Lao has gone." Yun Fei's face became a little ugly. It doesn't need to be said at all. 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, I 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 view, it is not. No important project in the Institute is about to make a breakthrough.

"Isn't Sun Lin here?" For some important figures in the 91 Research Institute, the old man naturally knows. It can be said that without sun Lin and situ Heyun, a group of old men from the National Academy of machinery and the Institute of automation, it would not have made such rapid research progress.

Of course, it is impossible to make such rapid progress without some tips from the young man Yunfei and large-scale research capital investment.

These technologies can not be controlled in the hands of the state. Many people are very dissatisfied. Without sun Lin and situ Heyun, who were originally academicians of the National Academy of Sciences, the 91 Research Institute could not be let go by the state as it is now.

"Yes. Grandson, grandson has been here all this time. At present, our research institute is carrying out research in related fields such as five axis grinder. As the president of the Research Institute and also the person in charge of five axis, grandson naturally can't put down his burden. " Yunfei sees Deng Lanqing looking for someone to inquire about Sun Lin's whereabouts and takes over the old man's topic.

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

"Test shop? I said, "I always feel that there is something missing after the expansion of your research institute." The old man always felt that there was something missing from the scene of Yunfei Research Institute.

When I first came to the Institute, there was only one building. Many projects were being carried out in it. At the same time, there were a lot of equipment running on the site. The whole environment was very messy. Now in this tens of thousands of square meters area, only those machine tools for testing are running, and we don't see those debugged machine tools at all.

Now I realized that the experimental workshop was separated from the research project.

"Sir, the research on the five axis machining center here is some theoretical research and systematic research. The five axes are integrated in the next workshop. How about going there?" In the experimental workshop, there is a gift Yunfei is going to give to the old man.

Of course, only when you see the processing process of the five axis machine tool can you deeply understand the function of the five axis machine tool.

The old man didn't speak and nodded.

Deng Lanqing took the crowd to the door several meters wide next to him and introduced the situation: "at present, the function of the five axis NC machine tool we have developed is no different from that of the same type abroad. The gap lies in the accuracy. The theoretical accuracy is 0.012mm, which can reach the accuracy of 0018mm in the actual machining process, which is much lower than that of foreign top machining centers within 0,01mm, and even the actual machining accuracy within 0005mm... "

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

For such things, no one can help. China's CNC machine tools have been groping by themselves. The domestic mechanical and electronic foundation is not very good, and the start is very late. It's good to have such achievements now.

"There is no big gap with foreign countries!" The old man doesn't know how precise this data is, but such a small data has only a few percent difference. Therefore, he praised Yun Fei with satisfaction.

Such data, for people who do not understand, is completely tall. After all, people who are not professionals often come into contact with the most precise ones, that is, millimeters, counting by a few percent, or even a few thousandths of millimeters. It's very precise to think about it.

"Sir, can we compare this like this. Compared with the equipment exported to us from abroad, our precision is higher and the function is stronger. That's because the products they export to our country are the most low-end products. The five axis machining centers exported by Japanese to China, whether in Japan, the United States or Europe, can only be used for rough machining. The performance of Toshiba and Mitsubishi Heavy Industries' five axis CNC machine tools purchased by the first aviation institute and the third Aviation Institute is basically the accuracy level of those equipment used in foreign countries in the 1980s... "Yun Fei didn't expect that the old man who always cherished words like gold should give such an evaluation, and he couldn't help laughing bitterly.

China's leadership 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 only large, but also very large. In precision machining, it is not easy to improve the performance accuracy of processing equipment by even one thousandth. Foreign countries can reach that level because they completed industrialization early and have a very deep foundation in machinery, electronics and a series of related things. Spain, Italy and even France, because their foundation is not as good as that of the United States, Japan and Germany, they have always been able to produce only third rate waste machine tools for rough processing... "Yun Fei also wants to reach the top level in foreign countries at once.

Such things can only be thought about.

Technology is nothing else. It takes time to accumulate.

However, at present, the 91 Research Institute can have such achievements, which is enough to be proud of the domestic CNC industry.

"So? According to your current investment and progress, when can you reach the advanced level of foreign countries? " The old man nodded approvingly and asked Yunfei. Anyone, especially leaders, would like to see more internationally leading things in China.

This is the foundation of a country. If it falls behind, it will be beaten. This is something that all Chinese know. Otherwise, if China is humiliated by the great powers for a hundred years, it will really be in vain. No one will care if it is humiliated again.

Just like ah San, people originally belonged to a part of the empire that never sets, and they didn't care at all.

"According to the current research progress, if the domestic materials and talent reserves can keep up, the basic research field can also catch up. Within ten years, we can close the gap with the top level abroad. They may reach their level in the next 20 years, and perhaps surpass them in 50 years. " Yun Fei said very conservatively.

CNC machine tool is the embodiment of a country's comprehensive national strength, which can not be supported by a company.

At present, Jiuyi Research Institute can obtain such research progress, many of which rely on many enterprises with good relations with them, such as 132 plant, North heavy industry, Hal heavy industry, Erzhong, Dongqi group, etc., which are the technical support of state-owned enterprises at the top level of domestic peers in various fields.

In China, the 91 Research Institute is well deserved to be the first in automation, but in terms of basic materials, precision machinery manufacturing, equipment solutions and so on, Yunshi holding has no advantages at all. In particular, materials seriously restrict the performance of their equipment.

These enterprises that have a good relationship with the Jiuyi group have their own material factories and are also part of the National Institute of materials. Many technologies can obtain the most advanced military material technology owned by the state through these enterprises. This is undeniable. The research of 91 materials is not basic materials, but special materials that also belong to the military field and the top tool materials in the civil field.

After catching up with foreign countries for 20 years, Yunfei can only say it is possible.

China is developing, and so will foreign countries.

To study these technologies, in the early stage, as long as the national comprehensive strength keeps up, it will be very fast, but later, it will be slower. Just like the aerospace technology of human beings on earth, the former Soviet Union had established the international space station in the 1970s. Americans also said that they had landed on the moon. Unfortunately, these aerospace technologies have not made much progress. Mir is about to retire, and no country is ready to build a new space station.

The Americans, who landed on the moon decades ago, have never landed again for so many years to establish a lunar base and turn the moon, a resource rich satellite, into 52 states of the United States that have always had expansion ambitions. Will Americans have any idea?

It's not that Americans don't want to, but that Americans simply don't have the ability to do such things! The photos of Americans landing on the moon were fake! If Americans really have such technology, they will definitely build a more powerful space station than laomaozi, rather than relying on laomaozi's space station to carry out their experiments.

Space technology is something that all countries are vigorously studying. Americans spend tens of billions of dollars on it every year. Even when Yun Fei left his original world, he never landed on the moon again. And there is no new production plan for the large number of space shuttles after retirement
