Chapter 159

"OK." Liu Chi nodded and didn't care, so he continued his question: "the smelter will be purchased in about a month."

"Now I have a motor and bearing for ultra-high precision machine tool in my hand. The first test object has been out. If it is normal, I can build a 1um precision CNC machine tool at that time."

"1um precision seems not enough. If it is 0.5um, it is almost the same."

"Now the domestic limit accuracy is about 3um." Liu Chi turned his eyes: "you girl think this is Europe."

"In fact, what I am most worried about is the tool. If I don't have a strong enough tool, it will be very troublesome." Liu Chi said helplessly, "you should also know the defects of this system."

"Don't worry, I have a plan to be used." Zhou Meng pointed to the screen and said, "minimize it first."

"Where?" Liu Chi asked the design drawing.

"Step back."

"Back again."

"This, three tool linkage system." Zhou Meng pointed to a folder on the screen.

"Three tool linkage?" Liu Chi opened the folder with a little doubt.

A three tool system design appeared on the screen. After half a meeting, Liu Chi asked, "how do you adjust the accuracy of the three tool linkage?"

"Look here, there are detailed instructions."

"You still use spectral radiation to locate?" Liu Chi said helplessly, "how expensive are you?"

"Does this system still consider the cost?" Zhou Meng retorted.

"Well, I can't refute it. Now the main thing is the material."

"Well, didn't you just say that you have designed a motor with an accuracy of 0.5um? If we design the machine tool ourselves, it may exceed 1um."

"I have handed over the matter of ultra-high precision machine tools to the three of them."

"Is it possible to achieve 1um?"

"There should be no problem."

“......”

A community.

"Yingying, I don't eat at home at night."

"Brother? Are you going on a date? " Xiao Yingying's eyes moved from the TV and looked at Xiao Yunhao, who was well dressed. She was full of curiosity.

"Eat with friends." Xiao Yunhao shook his head.

"What should I do? My parents are not at home. I order takeout at home?" Xiao Yingying picked up her feet and leaned back with her head tilted and a dead man's tone.

"Why don't you go with my brother?" Xiao Yunhao thought and asked.

"Ah? No, I'd better order my own takeout. " Xiao Yingying shook her head: "I don't know your friends, so I still won't go."

"Yes, Hai Qing, his girlfriend Liu Bing, Chen Song and Liu Chi have met."

"Liu Chi..." Xiao Yingying was stunned and excited: "brother, I saw him last time, but I didn't recognize him. He probably doesn't remember me."

"When did it happen?" Xiao Yunhao looked suspiciously at his sister on the sofa.

"Years ago, it was midnight. At that time, he ate by himself, and I shared the table with him."

"Table collage?" Xiao Yunhao stared at Xiao Yingying with a puzzled face. On his face, he said: you've all worked together, don't you know?

Fooling me.

"Really, it was night. There were a lot of people in that hotel. There was no place to temporarily spell the table. In addition, the light was not very bright. I didn't see it for a long time. I didn't recognize it all at once."

Xiao Yingying added, "I didn't remember until I left."

"And then?"

"No, I can still catch up with him when people are gone. Besides, I've only seen him once and I'm not very familiar with him. Xiao Yingying shrugged her shoulders.

"We all know what we're afraid of. Hurry to change your clothes."

"..." half an hour later, they went out of the house.

Half an hour later, a farm in the suburbs.

Xiao Yingying followed Xiao Yunhao, looked at the ordinary small farm, looked around curiously and said, "brother, you eat here. I think what big hotels and clubs are."

"This place is good, delicious and affordable. Let's go. They may be here."

Xiao Yunhao added: "by the way, I just forgot to tell you that a girl will be a little younger than you. He came back from studying in Europe x bridge. There is a bump on her face. Pay attention to her speech later."

“？”

"Her name is Zhou Meng. She came back from Europe last night. The injury on her face was caused by an accident before. She hasn't recovered yet."

"Very big?"

"Yes, it's big and long. Be careful when you speak later."

"Yes!" Xiao Yingying nodded.

Through two corridors.

"Yunhao..."

"Chen Song." Xiao Yunhao waved and said, "are you so fast, has sister Zhou Meng arrived?"

"Here we are. Now we need you. Hurry up." Chen Song looked at the 'little attendant' behind Xiao Yunhao and said, "Yingying hasn't seen you for a long time."

"Brother Chen song is good. It's only a few days." Xiao Yingying gave Chen Song a big smile.

"I haven't seen you for a few days. It's beautiful again." Chen Song flattered him.

"Brother Chen Song, you really can talk. I'll introduce you to a beautiful woman later." Xiao Yingying winked at Chen Song.

"Just wait for you. Don't fool me. I can remember."

"No problem. I'll introduce my little sister to you later. She's beautiful."

“......”

The three talked for a while, walked around a corner and came to a box.

"Sister Zhou Meng." Xiao Yunhao saw the little beauty beside Liu Chi at a glance.

"Brother Yunhao, long time no see." Zhou Meng looked back and stood up.

"My sister, Yingying, meet me." Xiao Yunhao pulled out Xiao Yingying, who followed behind him: "Yingying, this is Zhou Meng, two years younger than you. This is Liu Chi, you've seen."

"This is Ye Yuxin, Liu Chi's daughter-in-law."

"Hello, sister, you are beautiful." Zhou Meng turned his eyes to Xiao Yingying.

“......”

"All sit, all sit. Is Chen Song paying this time?" Liu Chi looked at a circle of people standing and chatting, and was busy greeting.

"You should pay this time."

"I think Chen Song paid the bill. There are eight more times."

"I'm dizzy..."

"Zhou Meng finally came back. Don't you invite him once?" Li Haiqing mercilessly made up a knife.

"OK, I said you all miss me." Chen Song surrendered directly.

“......”

"Liu Chi, how's your motor?" After ordering, Li Haiqing watched several girls gather together, grabbed a handful of melon seeds from the fruit plate, and asked Liu Chi while he was eating.

"Not yet." Liu Chi shook his head.

"Bell, bell, bell..."

"I'll answer the phone first." Liu Chi looked at the call and made a quiet gesture. When the people were quiet, he took the answer button: "hello..."

"Liu Chi."

"Old Zhang?" Liu Chi was stunned and asked suspiciously.

"Are you busy now? I didn't expect my old man to call you."

"It's really a little unexpected. You always have something to do. Just ask someone to send a message. You don't have to call me in person." Liu Chi said bitterly!

It's probably not a good thing.

Now let old Zhang call in person.

I hope it won't be too difficult later.

"Seriously, if possible, I really don't want to call you." Old Zhang smiled bitterly.

"What's the matter?" Liu Chi asked suspiciously, "what do you say?"

"I'll ask Chen Luguang to give you a copy of the information later. You'll see. When you get the information, reply to me."

"OK, is the Internet inconvenient?" Liu Chi thought about it and said, "I eat out with my friends."

"It's not very convenient. In this way, I'll ask Xiao Chen to call you and ask him to deliver it to you."

"Good!" Liu Chi nodded and refused.

It's not convenient to leave now. Today is a "big meal" for Zhou Meng to celebrate his return home.

After Liu Chi hung up the phone, he directly called Chen Luguang's mobile phone. After some communication, Liu Chi sent the location.

"What's the matter? Something's wrong again?" Ye Yuxin knows who Zhang always belongs to in Liu Chi's mouth. Now he has called in person. It must be no small matter.

"I don't know yet. It's inconvenient to call. I won't know what happened until your uncle comes." Liu Chi shook his head.

"Yes!" Ye Yuxin answered.

“......”

an hour later.

Liu chifang touched his stomach and put down his chopsticks: "I'm full."

"So fast." Chen Songwen raised his head.

"You think everyone can eat like you." Li Haiqing on the side also put chopsticks and hit.

"You two can't talk well today. Why are you always against me?" Chen Song despised: "I don't eat more today. I won't lose my life."

"No way, who let you owe." Xiao Yunhao mercilessly made up an assist.

"Shit, I deserve it?" Chen Song stared at several bad friends discontentedly.

Liu Chi felt the vibration coming from his mobile phone. When he picked it up, he saw that the message sent by Chen Luguang had arrived, so he said to the crowd, "are you full, and you will withdraw when you are full."

"What's the matter? I'm busy?"

"Well, my friend is at the door." Liu Chi shrugged helplessly.

"Let's go. It's close anyway. We'll get together next time when we're free." Knowing that Liu Chi must be busy again, Li Haiqing opened his mouth.

"Go, go, go."

More than ten minutes later, Liu Chi sent them away and asked Ye Yuxin and Zhou Meng to wait on the side and get in Chen Luguang's car!

"What happened?" Liu Chi closed the door and asked Chen Luguang.

"This is the information. You can see if there is a way to solve it." Chen Luguang picked up a file bag from the side and handed it to Liu Chi.

"Good!" Liu Chi didn't talk nonsense. He opened the seal, pulled out the document and opened the first page.

Title: 21 HNA project

Half an hour later, Liu Chi got out of the car with a headache, waved to the two women, got in the car and went straight home.

It seems that the automatic equipment system can only be released first, but the preliminary work can be arranged first.

Liu Chi and Zhou Meng studied in detail at home for two days, and finally came to the conclusion that if the material can meet the requirements, the success rate will exceed 70%.

The cost is more than 20 billion, and if the loss is included, it must be at least 30 billion.

But fortunately, it's not a one-time investment.

Even if it is saved again, the initial investment will exceed 5 billion. A 1 million level constant temperature chamber and a set of supercomputer cluster!

If the calculation amount of pseudo artificial intelligence is used, at least three sets of Taihu Lake light level supercomputers are required to run, and at least four sets of standby computers are required.

Preliminary investment in materials.

wait......

The core intelligent system is written by ourselves.

After a whole set of calculations, 5 billion may not be enough.

Liu Chi looked at the documents of more than 100 kinds of materials and more than 80000 parts on the electric screen, but he didn't frown.

Pack the documents and send them to Chen Luguang.

"Hello, leader Chen, have you received the document I sent you just now?"

"Yes, I'm looking. What the hell are you, so many materials and rough parts?" Chen Luguang asked curiously.

"Help me find out how many can be processed for me. I have an experiment to use." Liu Chi is rather vague.

"Do experiments? So much? Are you fooling me? Are you making any equipment? "

"Well, I want a set of equipment." Liu Chi directly changed the topic: "help me ask the above. I want to buy four lights of Taihu Lake, can I?"

"What? You want to buy four? " Chen Luguang's materials have been put aside.

"Yes, four."

"Also for experiments?"

"Yes..."

"You want to go to heaven. You want four at a time?"

"Ask me if you can do it or not." Liu Chi was also helpless.

"I will report these two things to the above, but not necessarily, especially if you want so many materials." Chen Luguang felt it necessary to remind him.

"I know, how much is how much. Help me sort it out. Don't produce it first. Help me mark out what has. If not, I'll find a way. Of course, it's best if you can help me."

"OK, but you have a lot of materials. You need to sort them out. I'll inform you when there are results."

"OK." Liu Chi nodded and asked, "what about Zhou Meng? Is there any way to cure it? "

"There is hope, but it has not been determined yet. It will take two or three days or so before there is a result."

"OK, let me know when you have the result." Liu Chi was a little happy.

Finally, there's good news.

"What I told you two days ago, you serve dessert." Chen Luguang said.

"I know. When I handle everything, go and have a try."

"Good!"

"..." after Chen Luguang hung up Liu Chi, he took these materials and reported to the boss.

As soon as Liu Chi hung up Chen Luguang, Jiang Yu called.

"What's the matter with Jiang Yu?"

"Boss, just now Jiang Dinghong, general manager of Enron electric appliance, called and said that the rice cooker was almost ready. The production line personnel had been in place and the listing schedule could be put forward."

"Every month, 2.5 million sets of core devices give us No. 9 technology." Jiang Yuhui reports.

"You can arrange this. By the way, has the production line of our core device been in place?"

"Half of them are in place, because the production line of rice cooker is a little complex, and it will take about a month to complete them."

"Just now, Jiang Dinghong said that the advertisement for the rice cooker was ready to be shot. He wanted to ask Li Xiaoying for your opinion?"

"Li Xiaoying, she, whatever, I have no opinion." When it comes to the rice cooker, Liu Chi thought of Baisi in Eagle sauce and asked suspiciously, "didn't Baisi pull away 3.5 million sets of hot kettles years ago? How is it going? They're not on the market yet? "

"According to the itinerary, it should be in the hands of Baisi now, but I don't seem to see the relevant information." Jiang Yu added: "now bestplus has ordered 5 million orders. Starting from May this year, 500000 will be given to them every month."

"Since May, COFCO has supplied 2 million sets, and the remaining 1 million won 500000 by European Kaike group, and the last 500000 was divided up by some scattered companies."

"Keck group has such a thick skin? How many orders did he place? " Liu Chi asked curiously.

"After 3 million yuan, they paid the full amount at once, and the price rose by 10%, which was the last compensation." Jiang Yu explained.

"What about the rice cooker? How did Jiang Dinghong arrange it? "

"I didn't participate in the discussion on rice cookers, but Jingxin group took 500000 yuan a month, and the rest is still under discussion. COFCO also wants a share."

"It's only more than 2.5 million a month. The amount is too small to be divided." Jiang Yu said helplessly, "it's noisy over there. There's no less shooting on the table."

"Then leave them alone and let them deal with it."

"OK, boss, will the induction cooker be put on the agenda?" Jiang Yu said greedily, "after all, the company still has so many empty factories, and only two factories have been used for rice cookers."

"Since returning the original Huahong's order and basically automatic production lines, the personnel are very full now. They were too busy before, and now they don't do enough."

"Well, I'll think about it. You can ask Yuxin to work out the design first."

"OK, I'll talk to Manager Ye later." Jiang Yu was glad to hear Liu Chi loose his mouth.

“......”

After Liu Chi hung up the phone, he could finally turn his eyes to the motor.

Half way through the last experiment, I stopped. I have to make the motor and bearing first, otherwise the accuracy is a big problem.

When the motor and bearing are ready, there will be time to deal with what Mr. Zhang said.

If the motor doesn't come out, the automatic design system can't move.

The last error was 0.5g 0.95.

If the motor accuracy wants to reach 0.5um, it should reach 0.3g.

Liu Chi disassembled the previous motor.

The balance system shall be corrected and the rotor shall be reworked.

Magnetic field balance force.

Only when the balance force of the whole rotor is uniform, can we meet our own requirements, and there is the problem of force.

If it is a physical drill bit, it will exert force when the drill bit touches the blank. If it exceeds the working range, the accuracy will change.

The machining accuracy should be high. If it is at high speed, the problem of friction heat and force will occur;

If there is eccentric force, the value of centrifugal force is very large at high speed, that is to say, the work done belongs to reactive work;

This reactive work is finally dissipated in the form of heat, and there are requirements for strengthening the strength of the shaft, so it should be minimized. Therefore, the balance system should have the ability to adjust the balance.

If you want to keep the accuracy.

The speed of the motor must be increased as much as possible.

According to the formula of centrifugal force and rotating speed: F centripetal force = Mr ω^ 2=mv^2r=mvw=4π^2mrT^2

g=r × eleven point one eight × 10-6 ×( rpm)2

R is calculated in cm;

Effective centrifugal radius, that is, the length and rotation radius from the motor axis to the barrel bottom of the centrifugal pipe.

Conversion between revolution and centrifugal force:

R is the distance between the center of the motor rotating shaft and the inner wall at the bottom of the centrifugal casing;

Rpm is the revolutions per minute of the centrifuge;
