Smart Industrial Empire

"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 Yunfei, a busy man, appeared in his office, Situ Heyun hurriedly asked Yunfei to go to the experimental workshop.

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

The joint-controlled rotary table has been reduced by a third.Although it has not reached the level that Yun Fei said that the length and width are less than [-] centimeters, the liquid

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

For the military that urgently needs four-axis linkage CNC machine tools to carry out some military applications that have high requirements on shape and position tolerances, as long as they can produce

Products at the drawing stage are fine.

Therefore, when the miniaturization has just been completed and has not yet been finalized, and the accuracy is not very ideal, the military can't wait to

Placed an order for twenty sets.

For this, when Yun Fei knew about it, he scolded Zhao Xingbang severely.That guy is too shameless, he clearly said he was half of the family

As for the right to operate, that guy excused that his Jiuyi Heavy Industry had heavy production and had no time to produce, so he took ten sets of rotary tables and

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

Placing production orders from the military to factories under the control of the military is nothing more than putting money from the left hand into your right hand.

In the end, it was still in the pocket of the military.

"What is your positioning accuracy now?" Yun Fei was not in the mood to look at the rotary table at first, 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, and as long as its own CNC milling machine is produced, although

Four-axis machining centers cannot be produced, but four-axis milling machines are produced.Not bad.

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

I just forgot about the four-axis thing.

"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 He Yun said to Yun Fei.

The four-axis rotary positioning accuracy not only requires the control of the numerical control system, but also the control accuracy of the hydraulic servo system.but

Now Sun Lin didn't dare to touch the hydraulic chuck at all. After all, they were just getting started in this research.Can only be installed on the rotary table

Mechanical chuck on lathe.

"I think, if it takes a while to replace the 8-bit industrial control chip in their Long CNC system with a 32-bit industrial control chip, with your current hydraulic pressure

At the technical level, it should be able to achieve 0.05° accuracy.Huashu's Long CNC is originally designed for three-axis CNC milling machines and machining centers

Yes, the control of the four axes is still very reluctant. "Dragon CNC is designed by itself, what are its advantages and disadvantages. Yun Fei

This designer is even clearer than Qin Qingshan and others.

The numerical control 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 the 8-bit industrial control chip adds more than ten pieces.The whole system is three points bigger than before

One more.

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

It doesn't take up much space.Yunfei finally had no other choice.I can only order the Institute of Electronics under Tanalia to convert the modified system

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

"32-bit industrial control chips?

There are several chip production plants in Taiwan, and we may not even be able to get 8-bit industrial control chips in China.Look at those TV and refrigerator factories

Inside, most of them still use two or four industrial control chips! "As for Yun Fei's statement, Situ He Yun was noncommittal.

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

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

The production of his own 32-bit industrial control chip will definitely surprise this old guy who has been working in electronic circuits all his life.

The surprises prepared for them are as exciting as traveling westward with a crane.

Now, Yun Fei has nothing to do with these two old guys.If these two old guys know that they are working on 32-bit industrial control chips, in the end

It is estimated that it must 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 take one for nothing in the future.

Every year there are hundreds of millions, even billions of dollars worth of projects handed over to the state, or state-controlled factories.In the end, I won't get any benefit

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

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

Well, if they knew about the project I was working on now, they would probably rush to Jiuyi Heavy Industry even more frantically.

The Chinese have one of the worst habits - it is better to have broken pieces of jade than to have everything broken!In China, there are quite a few people who suffer from pink eye disease. If you can’t get it yourself,

No one else can get it either.Therefore, 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

Ruined in the bud.

In Yunfei's world, these guys destroyed many promising companies in the 90s.

When Yun Fei and Situ He Yun arrived at the experimental workshop, Sun Lin was directing some nine-level assembly equipment that Zhao Xingbang had transferred from whom he did not know.

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

"You guy, tell me, what are you looking for us old guys?" Sun Lin knew this when he saw Yun Fei and Situ coming to look for him together.

The kid is going to the Three Treasures Hall for nothing, otherwise, this kid wouldn't have been excitedly informed by his two old fellows that the prototype had been produced last time,

The kid ended up saying nothing about something they'd spent months working on.It's been almost a month now, nothing

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

"Uh, Mr. Sun, what you said made the boy seem like a snobbish person, how can you make the boy who has always been jealous of the second elder feel so embarrassed...

"Yun Fei secretly scolded the old thing who is getting better and better with age, and squeezed out a smile.

"You boy, don't be too brave. If you have anything to say, just say it directly. You are a doll in your teens. In my nearly seventy-year-old

What is the outfit in front of the boss? "Sun Lin knew that Yunfei must have something to do here this time. Otherwise, he wouldn't be here at this time. You know

He said that the factory had just started working not long ago, and Yun Fei, a young man who didn't have many capable men under his command, must have encountered difficulties, and with the smile on his face

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

Hearing Sun Lin's words, Situ He Yun realized that Yun Fei was different from the past.Can't help but patted his head secretly.

Sun Lin wiped his hands carelessly with the cotton gauze on the workbench, and led Yun Fei towards the office at the entrance of the workshop.

"Say, before us, what is there to say? What happened in your factory?" I went to the office.Sun Lin put in the office

A few guys behind who were drawing with pencils and rulers drove out, made a cup of tea for themselves with greasy hands, and then looked at Yun Fei seriously.

asked.

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

At the beginning, the two old guys were left behind because they wanted them to be free labor for themselves.Now it's over.Instead I don't know what to do

In other words, especially seeing the gray hair of the two old guys, it is even more difficult to say.

he knows.If the two old people agree to help themselves, if they want to come up with the basic design of a simple CNC milling machine in one month, they will have to work overtime every day.

It may not be possible to figure it out.With the temperament of the two old people, it is estimated that the room and board are light in the office.

"You boy, you're still in control now, fart as soon as you have a fart, or get out..." Seeing Yun Fei's sad face, Sun Lin kept looking at Yun Fei.

The faces of myself and Situ Laohuo turned, but they didn't say anything, so they couldn't help being angry.

Yun Fei sighed, he didn't really want to exploit these two old people who should have been caring for the rest of their lives, but if he didn't ask them, just

It is very difficult to rely on the Soviet Union to come to Savavsky, who is only a quasi-expert.These two old guys have been immersed in mechanics and electronics for a long time.

Life, especially if the research direction is still CNC machine tools, is not comparable to Savavsky.

"You mean, you want me and Situ to help you preside over the research of CNC milling machines and even machining centers?"

After the description of Yizhong Industry's current situation, the faces of the two old guys also became ugly.

The current domestic investment environment is really bad.Those people, their minds are too bad!

"Yes, the engineers from the Soviet Union, although they are mechanical, but they are not in the direction of CNC machine tools, so they are working on design

When counting, the limitations are very large.I would like to ask the two elders for help. Only when the CNC milling machine is produced in a short period of time, the difficulties faced by Jiuyi Heavy Industry will be solved.

Easy to solve.I am dissatisfied with you two, I am almost out of money now..." Yun Fei nodded heavily and said to the two elders.

"Didn't you borrow 3000 million from the bank? You brought back more than 1000 million from Huadu, and it will be useless so soon?" Although it was just for research

Yes, but for the tens of millions of money spent so quickly, the two old guys also gasped. (To be continued..)
