"Good. Liu Chi nodded and didn't care, so he continued the question just now: "The smelting factory, it will take about a month to complete the acquisition." ”

"Now I have a motor and bearing for an ultra-high-precision machine tool, and the first test has come out, and if it is normal, I can build a CNC machine tool with an accuracy of 1UM at that time. ”

"1UM ACCURACY, IT SEEMS THAT IT IS NOT ENOUGH, IF IT IS 0.5UM IT IS ABOUT THE SAME. ”

"NOW THE DOMESTIC LIMIT ACCURACY IS ABOUT 3UM. Liu Chi rolled his eyes: "You girl thinks this is Europe." ”

"I'm actually most worried about the knives, and if they don't have strong enough knives, it's going to be a problem. Liu Chi said helplessly: "You should also know the flaws of this system." ”

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

"Where?" asked Liu Chi, minimizing the blueprint.

"Back off. ”

"Retreat again. ”

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

"Three tool linkages?" Liu Chi opened the folder with some confusion.

A three-tool system design drawing appeared on the screen, and after a while, Liu Chi asked: "How to adjust the accuracy of your three-tool linkage?"

"Look here, there's a detailed explanation. ”

"Do you still use spectral radiation to locate this?" Liu Chi said helplessly: "How expensive are you, how can you come here." ”

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

"Well, I can't argue with that, but now it's all about the material. ”

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

"I've already handed over the matter of ultra-high-precision machine tools to the three of them. ”

"IS IT POSSIBLE TO REACH 1UM?"

"It should be fine. ”

“......”

A certain community.

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

"Brother, are you going on a date?" Xiao Yingying moved her eyes from the TV, looking at Xiao Yunhao, who was dressed properly, and her curiosity was bursting.

"Eating with friends. Xiao Yunhao shook his head.

"Then what should I do, my parents are not at home, I order takeout at home?" Xiao Yingying picked up her feet and leaned back, tilting her head in a tone that wanted to die.

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

"Oh, no, I'll order takeout myself. Xiao Yingying shook her head: "I don't know your friends, so I still won't go." ”

"I know, Hai Qing and his girlfriend Liu Bing, as well as Chen Song, Liu Chi, you have also seen it. ”

"Liu Chi ???" Xiao Yingying was stunned and energetic: "Brother, I saw him last time, but I didn't recognize him, and he probably doesn't remember me." ”

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

"Years ago, it was the middle of the night, and he was eating by himself, and I shared a table with him. ”

"Sharing the table?" Xiao Yunhao stared at Xiao Yingying with a puzzled expression, and his face said: You have all shared the table, and you still don't know each other?

Fool me.

"Really, it was night, there were a lot of people in that restaurant, and there was no place to share a table temporarily, and the lights were not very bright, so I didn't see it for a long time, and I didn't recognize it at once. ”

Xiao Yingying added another sentence after speaking: "I only remembered it after leaving." ”

"And after that?"

"It's gone, everyone is gone, I can still chase him, and besides, I've only seen him once, and I'm not very familiar with him. Xiao Yingying shrugged her shoulders.

"I know what I'm afraid of, so hurry up and change my clothes. ”

Half an hour after the "......", the two walked out of the house.

Half an hour later, somewhere in the suburbs.

Xiao Yingying followed behind Xiao Yunhao, looked at the ordinary small farm, looked around curiously, and said, "Brother, you are eating here, I thought it was a big hotel, a club, or something like that." ”

"It's a nice place, it's delicious and affordable, let's go, they might be there. ”

Xiao Yunhao added: "By the way, I forgot to tell you just now, there will be a girl who is a little younger than you, he came back from studying at the X-Bridge in Europe, and the chin on her face will pay attention to her speech." ”

“？”

"Her name is Zhou Meng, she only came back from Europe last night, and the injury on her face was caused by an accident before, and she is not well yet. ”

"Big?"

"Yes, it's big, it's a long one, and I'll be careful when I speak. ”

"Hmm!" Xiao Yingying nodded.

Pass through two corridors.

"Yun Hao..."

"Chen Song. Xiao Yunhao beckoned: "You guys are so fast, has Sister Zhou Meng arrived?"

"It's here, it's time for you, hurry up. Chen Song glanced at the 'little follower' behind Xiao Yunhao: "Ying Ying hasn't seen you for a long time. ”

"Brother Chen Song, it's only been a few days. Xiao Yingying gave Chen Song a big smile.

"I haven't seen you for a few days, and I'm beautiful again. Chen Song slapped it with a sycophant.

"Brother Chen Song, you are really good at talking, I will introduce you to a beautiful woman when I turn around. Xiao Yingying squeezed her eyes at Chen Song.

"Just wait for your words, don't fool me, I can remember. ”

"No problem, I'll introduce you to my little sister, it's beautiful. ”

“......”

The three of them chatted for a while, walked around a corner, and walked to a box.

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

"Brother Yun Hao, long time no see. Zhou Meng turned around and stood up when he heard this.

"My sister, Yingying, get to know me. Xiao Yunhao pulled Xiao Yingying, who was following behind, and pulled it out: "Yingying, this is Zhou Meng, two years younger than you, this is Liu Chi, you have seen it." ”

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

"Hello, sister, you are so beautiful. Zhou Meng moved his gaze to Xiao Yingying.

“......”

"Sit down, sit down, is Chen Song paying for it this time?" Liu Chi watched a circle of people standing and chatting, and hurriedly greeted.

"You'll pay for it this time. ”

"I think Chen Song paid for it, and there are 8 more times. ”

"I'm ...... dizzy"

"Zhou Meng finally came back, don't you invite it once?" Li Haiqing made up for it fiercely.

"Okay, okay, I said that you guys are thinking about me. Chen Song surrendered directly.

“......”

"Liu Chi, how is your motor?" After ordering, Li Haiqing watched several girls get together, grabbed a handful of melon seeds from the fruit bowl, and asked Liu Chi while snorting.

"Not yet. Liu Chi shook his head.

"Bell, bell, bell......"

"I'll take the phone first. Liu Chi glanced at the call, made a quiet gesture, waited for everyone to be quiet, and then answered the answer button: "Hey......"

"Liu Chi. ”

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

"I'm not busy now, I didn't expect my old man to call you. ”

"It's really a bit unexpected, if you have something to do, just ask someone to pass a message, and you don't need to call me personally. Liu Chi said with a bitter face!

This is probably not a good thing.

Now let Zhang Lao call in person.

I hope it won't be too difficult for a while.

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

"What's wrong?" Liu Chi asked suspiciously, "You say?"

"I'll ask Chen Luguang to give you a copy of the information in a while, you can understand it when you read it, you get the information, and then reply to me." ”

"Okay, isn't the network convenient?" Liu Chi thought about it and said, "I'm eating out with my friends." ”

"It's not very convenient, so I'll ask Xiao Chen to call you and ask him to send it to you. ”

"Okay!" Liu Chi nodded and refused.

Now the situation is not convenient to leave, today is a 'big meal' for Zhou Meng to celebrate his return to China.

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

"What's the matter, what's wrong again?" Ye Yuxin knew who Liu Chi was talking about, and now that his old man had called in person, it was definitely not a trivial matter.

"I don't know yet, it's inconvenient to talk on the phone, and I'll wait until your uncle comes over to find out what's going on. Liu Chi shook his head.

"Hmm!" Ye Yuxin responded.

“......”

An hour later.

Liu Chi touched his stomach and put down the chopsticks in his hand: "I'm full." ”

"So fast. Chen Song raised his head when he heard this.

"You think everybody is like you, so good at eating. Li Haiqing on the side also put chopsticks and struck.

"You two can't talk well today, why don't you keep scolding me. Chen Song said disdainfully: "I won't eat more today, I won't lose my life." ”

"No way, who made you owe the debt. Xiao Yunhao made up an assist.

"Damn, I deserve to be unlucky?" Chen Song glared at a few friends with dissatisfaction.

Liu Chi felt the vibration of the mobile phone, picked it up and saw that the message sent by Chen Luguang had arrived, so he said to everyone: "Have you eaten enough, just withdraw when you are full." ”

"What's wrong, you're going to be busy?"

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

"Let's go, it's close anyway, and we'll meet again next time when I'm free. Li Haiqing knew that Liu Chi must be busy again, so he spoke.

"Let's go. ”

More than ten minutes later, Liu Chi sent everyone away, let Ye Yuxin and Zhou Meng wait on the side, and got into Chen Luguang's car!

"What's the situation?" asked Liu Chi as he closed the car door and asked Chen Luguang.

"This is the information, you take a look at it first, is there a way to solve it. Chen Luguang picked up a document bag from the side and handed it to Liu Chi.

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

Title: "21 HNA Project"

Half an hour later, Liu Chi got out of the car with a headache, beckoned to the two girls, and went home directly after getting in the car.

It seems that the "Automatic Equipment System" can only be put on 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 materials can meet the requirements, the success rate will exceed 70%.

The cost is more than 20 billion, and if you count the loss, it will be at least 30 billion.

But fortunately, it is not a one-time investment.

Even if it is saved, the initial investment will exceed 5 billion, a 1 million-level constant temperature room, and a supercomputer cluster!

If the amount of computing is based on pseudo-artificial intelligence, then at least three sets of Taihu Light-level supercomputers will be required to run, and at least four sets of spare ones will be added.

Upfront investment in materials.

Wait a minute......

The core intelligent system is still written by itself.

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 80,000 accessories listed on the screen, and he frowned helplessly.

Pack the documents and send them to Chen Luguang.

"Hey, Team Leader Chen, have you received the document I sent you just now?"

"Received, I'm looking, what the hell are you, so many materials and blanks?" asked Chen Luguang curiously.

"You can help me find out how much can be processed for me, I have an experiment to use. Liu Chi said more vaguely.

"Experiments? So much? What are you fooling me? Are you making some kind of equipment?"

"Well, I want to equip a set of equipment. Liu Chi directly changed the topic: "Help me ask the above, can I buy four 'Taihu Light'?"

"What, you want to buy four?" Chen Luguang's materials were all thrown aside.

"Yes, four. ”

"Also for experiments?"

"...... right"

"Are you going to heaven, you need four at a time?"

"You can help me ask, and I'll talk about it if it works out. Liu Chi was also helpless.

"I'll report these two things to the above, but it doesn't work out, especially since you need so much material. Chen Luguang felt that there was a need to be reminded.

"I know, how many count, help me sort it out, don't produce it first, which ones you have, help me mark them out, and if you don't have them, I'll figure it out myself, of course it's best if you can help me do it. ”

"Okay, but you have a lot of materials, you have to sort it out in a little time, and I'll let you know when there are results." ”

"Okay. Liu Chi nodded and asked, "How is Zhou Meng's matter?" Is there a way to cure it?"

"There is hope, but it is not yet certain, and it will take about two or three days for the results to come to fruition. ”

"Okay, let me know when the result is available. Liu Chi said a little happily.

Finally, there is good news.

"What I told you two days ago, you have a snack. Chen Luguang said.

"I know, when I'm done with everything I'm doing, I'm going to give it a try. ”

"Good!"

"......" After Chen Luguang hung up Liu Chi's phone, he took these materials to report to the big guy.

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

"Is there anything wrong with Jiang Yu?"

"Boss, just now Jiang Dinghong, general manager of Enron Electric, called and said that the rice cooker is basically ready, the production line personnel are in place, and the listing schedule can be raised. ”

"Every month, 2.5 million core devices are sent to our No. 9 technology. Jiang Yu reported.

"You can arrange this, by the way, is the production line of our core device in place?"

"Half of it is in place, because the production line of the rice cooker is a bit complicated, and it will take about a month to get it all in place. ”

"Jiang Dinghong said just now that the advertisement for the rice cooker is ready to be filmed, and he wants to ask Li Xiaoying what your opinion is?"

"Li Xiaoying, she, whatever, I don't have any opinion. Speaking of the rice cooker, Liu Chi thought of Eagle Sauce's Best, and asked suspiciously: "Didn't Best's take away 3.5 million sets of hot water kettles a year ago?

"According to the itinerary, it should be in the hands of Best now, but I don't seem to see the relevant information. After Jiang Yu finished speaking, he added: "Now Best has placed 5 million orders, and from May this year, 500,000 will be sent to them every month." ”

"Starting from May, 2 million sets will be supplied to COFCO, and the remaining 1 million will be 500,000 by the Keck Group in Europe, and the last 500,000 will be divided among some scattered companies. ”

"Keck Group is so thick-skinned, how many orders has he placed. Liu Chi asked curiously.

"After 3 million, they paid the full amount at once, and the price rose by 100 to 10, which is considered the compensation last time. Jiang Yu explained.

"What about the rice cooker?

"I didn't participate in the rice cooker, but Jingxin Group took 500,000 yuan a month, and the rest is still being discussed, and COFCO also wants to get a piece of the pie. ”

"It's only more than 2.5 million a month, which is too small and not enough. Jiang Yu said helplessly: "It's noisy over there, and the table is not less." ”

"Leave them alone, let them handle it themselves. ”

"Okay, boss, is the induction cooker also on the agenda?" Jiang Yu said a little greedily: "After all, the company still has so many empty factories, and the rice cooker only uses two factories." ”

"Since the withdrawal of the original Huahong's order, plus the basic automatic production line, now the staff is very sufficient, I was too busy before, and now I can't do enough. ”

"Well, I'll think about it, you can let Yu Xin get the design out first. ”

"Okay, I'll communicate with Manager Ye in a while. Jiang Yu said happily when he heard Liu Chi.

“......”

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

Halfway through the last experiment, I stopped, and I had to manufacture the motor and bearings first, otherwise the accuracy would be a big problem.

When the motor and bearing are ready, there is 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.

If the motor accuracy wants to reach 0.5UM, it should reach 0.3 grams.

Liu Chi disassembled the previous motor.

The balancing system should be re-corrected and the rotor should be re-worked.

Magnetic field equilibrium.

Only when the balance force of the entire rotor is even, can you still meet your own requirements, and there is also the issue of considering the force.

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

The machining accuracy should be high, and if it is in a high-speed state, it will cause the problem of friction and thermal heel;

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

In the end, this useless work is diverged in the form of heat, and there is also a requirement for strengthening the strength of the shaft, so it should be reduced as much as possible, so 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 rotational speed: F centripetal force = mrω^2 = mv^2 / r = mvw = 4π^2mr/T^2

g

r is calculated in cm;

The effective centrifugal radius is the radius of rotation of the length from the axis of the motor to the bottom of the barrel.

Conversion of revolutions to centrifugal force:

r is the distance between the center of the motor shaft and the inner wall of the bottom of the centrifugal casing;

rpm is the number of revolutions per minute of the centrifuge;
