"Xiaoyun, why do you have time to come here? Come on, help us see how we can improve the positioning accuracy of our rotary table..." See

When Yun Fei, a busy man, appeared in his office, Situ Heyun hurriedly asked Yun Fei to go to the experimental workshop.

Since last time Yunfei complained that the rotary table they designed was too big, they quickly replaced the entire hydraulic system and electronic circuit system.

The jointly controlled rotary table has shrunk by one-third. Although it has not reached the level of less than forty centimeters in length and width as Yun Fei said, the liquid

The pressure workstation and the pneumatic workstation together are even as big as a machining center.

For the military that urgently needs four-axis linkage CNC machine tools to perform some tasks that have very high requirements on form and position tolerances, as long as it can produce

Products at the drawing stage are fine.

So when the miniaturization had just been completed, but it had not yet been completed, and the accuracy was not in an ideal state, the military couldn't wait to

Placed an order for twenty sets.

Regarding this, Yun Fei scolded Zhao Xingbang severely when he first found out about it. That guy was so shameless, and he clearly promised that half of the family would

The guy with the right to operate the company used the excuse that his Jiuyi Heavy Industry had heavy production and no time to produce, so he used the ten sets of rotary worktables and the equipment that were supposed to be his.

The supporting hydraulic and pneumatic workstations were handed over to its own machining factory.

By placing production orders from the military to factories under the control of the military, this guy is just putting money from his left hand to his right hand. No matter how he does it, in the end,

In the end, it was still carried in the pockets of the military.

"What's your positioning accuracy now?" Yunfei was not in the mood to look at the rotary table, but thought that if his CNC

If the milling machine is to be produced within half a year, it still needs the strong support of these two veterans. In addition, as long as its own CNC milling machine is produced, although

It cannot produce a four-axis machining center, but it can produce a four-axis milling machine. It is not bad.

The four-axis CNC milling machine is definitely a big killer in China in this era!

I had completely forgotten about the four-axis just now.

"Now our rotation accuracy can only be controlled within 0.1°, which is six points. If we want to achieve the 0.01° rotation error you mentioned, I

We still have a long way to go." Situ Heyun said to Yun Fei.

The rotation positioning accuracy of the four-axis requires not only the control of the CNC system, but also the control accuracy of the hydraulic servo system. However,

Now Sun Lin doesn't dare to touch the hydraulic chuck at all. After all, they have just started to research this area. They can only install it on the rotary workbench.

Mechanical chuck on a lathe.

"I think if Huashu replaces the 8-bit industrial control chip in their Long CNC system with a 32-bit industrial control chip, with your current hydraulic

The technical level should be able to achieve 0.05° accuracy. Huashu's Long CNC was originally designed only for three-axis CNC milling machines and machining centers.

Yes, the four-axis control is still very difficult. "Long CNC is designed by itself. What are its advantages and disadvantages? Yun Fei

This designer is even clearer than Qin Qingshan and others.

The CNC system used to control the fourth-axis rotary table was modified in Yunfei's Jiuyi Heavy Industry. Although only

It only controls one more rotary axis than the three-axis machining center, and more than ten more 8-bit industrial control chips are added. The entire system is three times larger than the original one.

One more than one.

If it is still placed on the machining center as before, there is no way at all. After all, those imported machining centers have PLC control panels.

The space it occupies is not very large. In the end, Yunfei had no choice but to instruct Tanalia's Electronics Research Institute to convert the modified system.

The system is made into an independent control cabinet, which is placed next to the machine tool.

"A 32-bit industrial control chip? This is simply a dream, you know. Nowadays, it is difficult to obtain 16-bit industrial control chips in our country. If it were not for Taiwan

There are several chip manufacturers in Taiwan. We may not even be able to produce 8-bit industrial control chips in China. Look at those TV and refrigerator manufacturers.

Most of them use two- or four-digit industrial control chips!" Regarding Yun Fei's statement, Situ Heyun was noncommittal.

How many people in China don’t know about the situation in China?

Regarding Situ He Yun's words, Yun Fei was also noncommittal. The corners of his mouth just curled up slightly and then returned to a calm expression. At that time, he would

The production of our own 32-bit industrial control chip will definitely give this old guy who has been working in electronic circuits his whole life a surprise. I hope he will not be fooled by himself.

The surprises prepared for them are as exciting as traveling westward.

Now, Yun Fei is taking care of these two old guys. If these two old guys know that he is working on 32-bit industrial control chips, it will end

I guess it will be like this rotary table.

There are quite a few state-owned electronics factories, but most of them are producing some backward products. I can't afford to waste one of them every time in the future.

Every year, hundreds of millions or even billions of dollars of projects are handed over to the state or state-controlled factories. In the end, you get nothing.

, no one wants to be taken advantage of all the time.

Especially this time, the crisis of Jiuyi Heavy Industry is largely due to the methods of those guys who wanted to snatch Jiuyi Heavy Industry from me last time.

, if they knew about the project they were working on now, they would probably pounce on Jiuyi Heavy Industry even more crazily.

Chinese people have one of the worst habits - they would rather have broken jade than complete tiles! In China, there are many people suffering from pinkeye. What they cannot get,

Others cannot get it. So when those people know that they will not get the benefits that Jiuyi Heavy Industry will bring, they will definitely grit their teeth and give Jiuyi Heavy Industry to

Destroyed in the bud.

In Yun Fei's world, these guys destroyed many companies with great development prospects in the 1990s.

When Yun Fei and Situ Heyun arrived at the experimental workshop, Sun Lin was commanding several level nine assemblies that Zhao Xingbang had transferred from unknown sources.

The fitter dismantled a hydraulic rotary table that was only half a meter square.

"Tell me, you guys, what do you have to do with us old guys?" Sun Lin knew this when he saw Yun Fei and Situ coming to see him.

This kid doesn't go to the Three Treasures Hall for anything. Otherwise, this kid wouldn't have had two old guys excitedly inform him that the prototype had been produced.

As a result, this guy said that the thing that they spent several months to come up with was useless. In the end, it has been almost a month now, and there is nothing.

When I came to this experimental workshop again, I didn't just come to see myself and Situ as usual.

"Well, Mr. Sun, what you said makes me seem to be an extremely snobbish person. How can you put this young man who has always been in love with his second elder, Ba Xinba, so embarrassed...

" Yun Fei secretly scolded the old guy who became more sophisticated as he got older, while forcing out a smile.

"You kid, don't be too pushy. If you have something to say, just say it directly. You are a teenager and I am almost seventy years old.

What are you pretending to be in front of the boss?" Sun Lin knew that Yun Fei must have something to do when he came here this time. Otherwise, he wouldn't show up here at this time. You know

He said that the factory had just started operation. Yun Fei, a young man who did not have many capable men under him, must have been in trouble. Plus the smile on his face

The content is so reluctant, if it can still be unclear.

After hearing Sun Lin's words, Situ Heyun realized that Yun Fei was different from before. He couldn't help but secretly patted his head.

Sun Lin wiped his hands haphazardly with the cotton yarn on the workbench and led Yunfei towards the office at the entrance of the workshop.

"Tell me, is there anything else that can't be said before us? What happened in your factory?" When they arrived at the office, Sun Lin

A few guys who were drawing pictures with pencils and rulers were rushed out, and after making themselves a cup of tea with greasy hands, they looked at Yun Fei seriously.

asked.

Yun Fei hesitated a bit, not knowing what to say.

The reason why I left these two old guys behind was to use them as free labor for me. Now that things are over, I don’t know what to do.

Well, especially when I saw the gray hair of the two old guys, I couldn't say it even more.

He knew that if the two old men agreed to help him, if they wanted to come up with the basic design of a simple CNC milling machine in a month, they would have to work overtime every day.

It may not be possible to do it. With the tempers of the two old people, it is probably easy to live and eat in the office.

"You kid, you're still holding back now. If you fart, just let it go, or get out of here..." Sun Lin saw Yun Fei's sad face and his eyes kept moving.

The faces of myself and Mr. Situ turned around, but they didn't say anything was wrong, and they couldn't help but get angry.

Yun Fei sighed. He didn't really want to exploit these two old people who were supposed to live a long life, but if he didn't beg them, he would just

Savavsky was only a quasi-expert from the Soviet Union, so it was very difficult. These two old guys had been immersed in mechanics and electronics for a long time.

Throughout his life, especially his research direction was CNC machine tools, which was not something Savavsky could compare with.

"What you mean is that you want Situ and I to help you lead the research on CNC milling machines or even machining centers?" After listening to Yun Fei's comments about Jiu

After describing the current situation of No. 1 Heavy Industry, the faces of the two old guys became ugly.

The current domestic investment environment is really bad. Those people have such bad intentions!

"Yes, although the engineers from the Soviet Union are in the mechanical field, they are not people in the field of CNC machine tools, so they are engaged in equipment manufacturing.

When designing, there are great limitations. I would like to ask the two elders for help. Only by building the CNC milling machine in a short time can the difficulties faced by Jiuyi Heavy Industry be solved.

Easy to solve. I am not satisfied with you two, and I am almost out of money now..." Yun Fei nodded heavily and said to the two elders.

"Didn't you get a loan of 30 million from the bank? You brought back more than 10 million from Huadu, and you lost it so quickly?" Although it was just for research.
Chapter completed!
