Chapter 144

"... in the research of CNC machine tools, such a tool belongs to plug-in, which can also be called a more complex tooling. As long as the control problem can be solved, more than half of it can be completed. As for how to solve it, we must wait until the equipment is in place, constantly find problems in the production process of the machine tool, and then improve. Of course, the rotation accuracy of hydraulic station and rotary worktable is also very important. Otherwise, the rotation error is too large and the indexing accuracy cannot be effectively controlled. Even if we do this project, there will not be much development prospect. Well, this is the direction of our research and the division of each module. How to allocate the specific personnel can only be arranged by Mr. Sun and Mr. situ. "

Yun Fei had a headache for the people who listened carefully and took notes in front of him like primary school students. Except Sun Lin and situ Heyun, the others were young people in their twenties and thirties. They were all at a loss about what he said.

Expect these guys to get this out? Yunfei feels very unreliable. Although these are top students with several years of research experience, Yun Fei estimated that they have no problem with the hydraulic station, the AC servo motor used to drive is too suspended, so he can only choose the DC stepping motor almost eliminated in later generations as the control motor of the rotating workbench.

Sun Lin and situ Heyun took their disciples to Chengdu as early as a few days ago. Yunfei has been waiting in Chengdu for nearly a month now, and he doesn't know what the Chengdu city government will do in the end. That time, he told Fang Linyuan that he won't give a penny more, nor will he promise to provide ordinary posts. Of course, Yun Fei also said that if Chengdu could not solve their land use problem, he would consider seeing the factory in Guocheng, which is only 200 kilometers away from Chengdu.

The of Guocheng is near the Jialing River, and the water transportation conditions are also very good. 3000 ton cargo ships can drive directly from Guocheng to the estuary of the Yangtze River. It is not far from Chengdu and Shancheng, the two cities with the most developed economy and industry in Southwest China. If it were not for this era, the infrastructure of Guocheng was indeed too poor, 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 Chengdu municipal government intervened in the land acquisition work. In just over a week and less than ten days, the 3000 mu land required by Yunfei was obtained. Yun Fei didn't know or didn't bother to know the specific operation plan of Chengdu city government. He was thinking about the way out of 9327 every day.

"Xiao Yun, is it too irresponsible for you to draw such a schematic diagram and leave the project to us?" Situ Heyun felt that he and Sun Lin had been fooled by Yunfei. When the contract was signed, I didn't expect that now Yunfei only roughly worked out a schematic diagram, that is, the layout of various components, and explained the whole principle again. It seems that he will be the shopkeeper. This can't work.

In other words, the cloud not only put forward a theory, but let them design, test and finally make the results according to this theory, but it has little to do with them.

"Mr. situ, you can't say that, can you? Let's introduce to you today. We will first implement each module to the group according to their professional direction. Then I communicate with each group separately, so that I won't waste a lot of time. Do you think it is appropriate for us to talk about mechanical principles and design in front of electronic circuit experts, or about the principles and design of electronic circuits in front of mechanical experts? " Yun Fei explained to situ Heyun with a smile.

These two old goods, I don't know whether they are about to retire or what's going on. They had a hard day at the Research Institute in the capital, waiting for their temporary settlement in Chengdu's economic development zone. The two old goods came here with a group of disciples and grandchildren.

Chengdu is the city with the largest number of Southwest universities in China, especially Chengdu University of technology, Chengdu University of Electronic Science and technology, and several universities with southwest titles. At that time in the non cloud world, the trained talents can be regarded as real elites in terms of machinery and electronics. Although they can not be compared with Huaqing and Capital University in the capital, they are not far away.

We know our own business. Yunfei doesn't have the confidence to network to those elite graduates majoring in machinery or electronics of Capital University at the first time without guaranteeing distribution in the country. Even less confident, 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 Chengdu, a mainland city that will rise due to the western development strategy two thousand years later.

Chengdu and several famous universities nearby cannot be compared with those in the capital in terms of reputation, and there is no way to compare resources. The reason why Yunfei seduced two old goods to Chengdu is not just to let them work for themselves. If the presidents of these universities in Chengdu are not idiots, after knowing that these two old goods have arrived in Chengdu, they will definitely beg these two old goods to serve as visiting professors in their schools.

In this way, among the college students who graduated from Chengdu in the future, the talents online will be much higher than the quality of the same graduates in the 1990s.

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

"Are you really going to do that? Why didn't you mention such an idea to us a few days ago? " Sun Lin is also worried that Yunfei is playing with himself. They don't know why Yun Fei, a young man, knows so much at such an age. Jiang Zhuqing can't train such a young man.

They have been immersed in their respective fields for decades and are both authorities in their respective fields. However, from the beginning of contact with Yunfei, I understood that Yunfei, a child, said these things, not just theoretical knowledge that can be obtained from reading. That's why they are willing to catch up with Chengdu from the capital. They want to understand where Yunfei got this knowledge and what else Yunfei will have.

Especially when they knew that the system of Huashu was provided by Yunfei, the two old goods understood that with the research of Jiang Zhuqing and others behind closed doors, it was impossible to come up with such a system. Yunfei is definitely hiding something, but from the various intelligence analysis provided by Zhao Xingbang, Yunfei has not even contacted foreigners except the foreign liar group posing as Deere company.

Everyone knows that the most advanced CNC technology in the world is not in China in Europe, America and Japan. Yun Fei, an 18-year-old young man, suddenly came up with a mid-range CNC system. Do you really believe he was born to know it? Two old atheists can only talk nonsense with a black face.

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

Therefore, when Yunfei informed them to wait a few more months to Chengdu, the two old goods came to Chengdu with their disciples and grandchildren regardless of everything. According to their level, they could have taken the plane from the capital to Chengdu, but their disciples and grandchildren could only take the train, so the two old goods went to Chengdu by train.

Now that they have come, Yunfei has no way to arrange the party to Funan Hotel, and then arrange Lin Yajun, who has been familiar with the major tourist attractions of Chengdu with Wang Qingfeng, to take the party to Chengdu. The factory has just started to break ground. There are no conditions for research at all. What else can we do without arranging for these advanced labor forces to play in advance?

Unexpectedly, just three days later, after walking around Chengdu like a horse and a flower, the two old goods killed their disciples and grandchildren to the hotel where Yunfei lived in difficult conditions, no longer left, and pestered Yunfei every day to start the research of the project. Finally, there was no way. Yunfei had to pack the small hotel and settle the party down. They are also worried that the small shops outside without any health permission will eat two old goods and have found a aunt in her fifties to cook.

When there was still no shadow in the factory, Yunfei already had dozens of wage earners

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

Yun Fei seldom misses the era when he didn't need manual drawing. As long as a computer, a software and any design can be made, people don't have to lie on the drawings all day, causing backache and slow progress. But there is no way. The computers and software of this era are not mature. Especially those drawing software, CAD and CAXA, whose functions are not perfect in this era, can not be used to make complex assembly drawings.

Sun Lin was in charge of machinery and situ Heyun was in charge of electronics. The next day, they began to work in full swing with the people they brought. The hot weather did not affect their enthusiasm at all.

"Mr. Sun, I really don't understand the hydraulic station. It depends on you. I seriously thought about the work of turning. The indexing motion of NC indexing head is driven by servo motor or stepping motor through coupling, so as to rotate the indexing head. For the indexing head we want to make, the indexing accuracy must be less than 0.05 °, and the point position control can operate automatically under manual and program control. It is estimated that you need to communicate with Mr. situ. Clamping is achieved by a set of pneumatic clamping devices controlled by solenoid valves. " Yun Fei said to Sun Lin what he had learned about the fourth axis.

Speaking of this CNC rotary table, Yun Fei doesn't understand it very well. After all, in the original world, he was just an ordinary technician. For these things, he only knew some fur. However, the fur he knows through various ways is a great thing for the experts who have entered the bottleneck in this era.
