“…… In the research of CNC machine tools, such a plug-in, can also be called a more complex tooling, as long as the control problem can be solved, even if more than half is completed. As for how to solve it, it is necessary to wait until the equipment is in place, and constantly find problems in the production process of the machine tool, and then improve. Of course, the hydraulic station, as well as the rotation accuracy of the rotary table, this is also very important, otherwise, the rotation error is too large, the indexing accuracy can not be effectively controlled, even if our project is made, there will not be much development prospects. Well, the direction of our research and the division of each module are like this, and how to allocate specific personnel can only be arranged by Mr. Sun and Mr. Situ. ”

Yun Fei had a headache at the people in front of him who were listening carefully to the class and taking notes like elementary school students. Except for Sun Lin and Situ Heyun, the others were all young people in their twenties and thirties, and they were all at a loss for what he said.

Counting on these guys to get this out? Yun Fei felt very unreliable. Although these are high-achieving students with several years of research experience, Yun Fei estimates that there is no problem for them to come up with the hydraulic station, but the AC servo motor used to drive it is too suspended, so he can only choose the DC stepper motor that has almost been eliminated in later generations as the control motor of the rotary table.

Sun Lin and Situ Heyun had already arrived in Rongcheng with their disciples and disciples a few days ago. Yun Fei and the others have been waiting in Rongcheng for almost a month now, and they don't know what to do with the Rong City Government, that time he told Fang Linyuan that he would not pay a penny more, and he would not promise to provide ordinary jobs. Of course, Yun Fei also said that if Rongcheng City could not solve their land use problem, he would consider seeing the factory in Guocheng, which is only 200 kilometers away from Rongcheng in a straight line.

Guocheng is on the edge of the Jialing River, and the water transportation conditions are also very good, and the 3,000-ton cargo ship can directly drive from Guocheng to the mouth of the Yangtze River. It is far away from Rongcheng and Shancheng, the two most economically developed and industrially developed cities in southwest China. The distances are not very far. If it weren't for the fact that the infrastructure of Guocheng was really poor in this era, and it was too far away from the production base of steel raw materials, Yunfei would first consider building a factory in Guocheng.

After Yunfei threatened to transfer the investment land, the Rongcheng city government intervened in the land acquisition work, and in just over a week, in less than ten days, Yunfei's 3,000 acres of land were in hand. The specific operation plan of the Rongcheng City Government, Yun Fei didn't know about the road, and he didn't bother to know the road, he was thinking about the way out of 9327 every day.

"Xiaoyun. Isn't it irresponsible to just draw such a schematic and throw this project to us? Situ Heyun felt that he and Sun Lin had fallen for Yun Fei. I signed the contract at the beginning, but I didn't expect that now Yun Fei only roughly made a sketch, that is, the layout diagram of various components, and then explained the whole principle again, it seems that he has to be the shopkeeper, which is not good.

In other words, Yun Fei just came up with a theory. Let them design according to this theory, test it, and the results that come out of it have little to do with them.

"Mr. Situ. You can't say that, right? Today, let's introduce to you, we will first implement each module into the group according to their respective professional directions. Then I communicate with the people in each group individually, and that's it. You won't waste a lot of time. Do you think that we should talk about the mechanical principles and design in front of the experts in electronic circuits, or the principles and design of electronic circuits in front of the mechanical experts. Is it appropriate? Yun Fei smiled and explained to Situ Heyun.

These two old goods, I don't know if Lu Dao is about to retire or what's going on, they have been idle for a day in the research institute in the capital, waiting for themselves to temporarily settle down in the economic development zone of Rongcheng, and the two old goods ran here with a group of apprentices and grandchildren.

Rongcheng is the city with the most universities in southwest China, especially Rongcheng Institute of Technology, Rongcheng University of Electronic Science and Technology, and several universities with the title of southwest. At that time in Yunfei's world, in terms of machinery and electronics, the talents cultivated could be regarded as real elites, although they could not be compared with Huaqing and Capital University in the capital, but they were not far behind.

Yun Fei does not have the confidence to be able to access the elite graduates of the capital university who majored in mechanical or electronics at the first time when the state did not allocate them. I am not confident that those graduates will honestly work for themselves for a lifetime. Therefore, he rejected all kinds of temptations of the two old goods, and insisted on going to Rongcheng, a mainland city that would rise after 2,000 years because of the western development strategy.

Rongcheng and several famous universities in the vicinity cannot be compared with those universities in the capital in terms of reputation, and there is no way to compare them in terms of resources. The reason why Yun Fei lured the two old goods to Rongcheng was not just to let them work for themselves. If the presidents of these universities in Rongcheng were not idiots, they would definitely beg these two old men to come to their schools as visiting professors when they arrived in Rongcheng.

In this way, the talents that Yun Fei will find among the college students who graduated in Rongcheng in the future will be far higher than the quality of his graduates in the nineties.

What is most important in the 21st century? Talent!

"Are you really going to do that? Why didn't you mention such an idea to us the other day? Sun Lin was also worried that Yun Fei was playing with the two of them. They didn't know how to do it, Yun Fei, a young man, why did he know so much at such a young age, Jiang Zhuqing would never be able to cultivate such a young man.

Both of them have been immersed in their respective fields for decades and are both authorities in their respective fields. But from the very beginning of my contact with Yun Fei, I understood that these things that Yun Fei, a child, said were not just theoretical knowledge that could be obtained by reading books. That's why they willingly chased from the capital to Rongcheng. They want to find out where Yun Fei got this knowledge from, and what else Yun Fei will have.

Especially when he knew that the system was provided by Yun Fei, the two veterans understood that with the research of Jiang Zhuqing and others behind closed doors, it was impossible to make such a system. Yun Fei is definitely hiding something, but from the various intelligence analysis provided by Zhao Xingbang, Yun Fei has not even been in contact with foreigners except for foreign scammer groups pretending to be Deere Company.

Everyone knows that the most advanced CNC technology in the world is not in China in Europe and the United States, in Japan. Yun Fei, an eighteen-year-old young man, suddenly made a set of mid-range CNC system, do you really believe that he was born to know? The two old atheists can only say nonsense with a black face.

If there is a research team behind Yunfei that they don't know, then this research team will definitely raise the industrial level of the entire China by several grades.

Therefore, when Yun Fei informed them to wait a few more months and then return to Chengdu, the two old goods came to Rongcheng with their apprentices and grandchildren desperately. According to their level, they could have taken the plane from the capital to Rongcheng, but their disciples and grandchildren could only take the train, so the two old goods took the train to Rongcheng.

Since they came, Yun Fei didn't have any way, arranged the group to the Zhunan Hotel, and then arranged for Lin Yajun, who had already followed Wang Qingfeng to familiarize himself with the major tourist attractions in Rongcheng, to take the group to visit Rongcheng. The factory has just begun to break ground, and there are no conditions for research at all, so what can you do without arranging for these high-level laborers who came in advance to play?

Unexpectedly, in just three days, after visiting Rongcheng like a flower, the two old men took their apprentices and grandchildren to the hotel where Yun Fei lived in difficult conditions and never left, pestering Yun Fei every day to start the research of the project. In the end, there was no way, Yun Fei could only charter this small hotel and settle the group. I was worried that the small shops outside without any health permits would eat two old goods, and I also found an aunt in her fifties to cook for the locals.

When there was still no shadow in the factory, Yun Fei already had dozens of salaried people under him......

After Yun Fei finished speaking, the two old men each assigned their disciples and grandchildren. Then he began to force Yu Xiaogang, who was promoted to purchasing director, to go to the city to buy all kinds of design drawings, pencils, rulers, compasses and other necessities.

Yun Fei rarely misses his time when he didn't need to make drawings by hand. As long as there is a computer and a piece of software, any design can be made, and people don't have to lie on the drawings for a day to get back pain, and the progress is still very slow. But there is no way, the computers of this era, the software of this era, are not yet mature. Especially those drawing software, CAD, CAXA, these functions are not perfect in this era, and they cannot be used to make those more complex assembly drawings or anything.

Sun Lin was in charge of the mechanical aspect, Situ Heyun was in charge of the electronic aspect, and the two of them began to work in full swing with the people they brought with them the next day, and the hot weather did not affect their enthusiasm at all.

"Old Sun, I really don't know about the hydraulic station, and it depends on you. I've really thought about turnaround work. The indexing motion of the numerical control indexing head is driven by a servo motor or a stepper motor through a coupling to drive a group of turbine worms, so that the indexing head rotates the indexing. The indexing head we want to engage in, the indexing accuracy must be less than 0.05 °, the point control, can be manually and automatically operated under the program control, this point, it is estimated that you need to communicate with Mr. Situ. The clamping is achieved by a set of pneumatic clamping devices controlled by a solenoid valve. Yun Fei said to Sun Lin what he had learned about the introduction of the fourth axis of the hanging.

Speaking of this CNC rotary workbench, Yun Fei himself doesn't understand it very well. After all, in the original world, he was just an ordinary technician, and he only knew a few superficial things about these things. However, the fur that he knows about the Tao through various ways is already a remarkable thing in the eyes of these experts who have entered the bottleneck in this era. (To be continued......)
