"Okay." Liu Chi nodded without paying attention, and continued with the previous question: "It will take about a month to complete the acquisition of the smelting plant."
"Now I have a motor and bearings for ultra-high-precision machine tools. The first test product has been released. If it works normally, I can build a CNC machine tool with a precision of 1um."
"The accuracy of 1um seems not enough. If it is 0.5um, it will be almost the same."
"The current domestic limit accuracy is about 3um." Liu Chi rolled his eyes: "You girl, you think this is Europe."
"Actually, what I'm most worried about is the knives. If we don't have strong enough knives, it will be very troublesome." 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 at the screen and said, "You minimize it first."
"Where?" Liu Chi asked, minimizing the design drawing.
"Back off again."
"Back off again."
"This is a three-tool linkage system." Zhou Meng pointed at a folder on the screen.
"Three tools linked?" Liu Chi opened the folder with some confusion.
A three-tool system design diagram appeared on the screen. After a while, Liu Chi asked: "How do you adjust the accuracy of your three-tool linkage?"
"Look here, there are detailed instructions."
"You still use spectral radiation for positioning?" Liu Chi said helplessly: "How come you are so expensive?"
"Does this system also consider cost issues?" Zhou Meng retorted.
"Well, I can't refute it. The most important issue now 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 reach 1um?"
"It should be fine."
"..."
A certain neighborhood.
"Yingying, I won't be at home for dinner tonight."
"Brother? Are you going on a date?" Xiao Yingying moved her eyes from the TV and looked at Xiao Yunhao, who was well-dressed, with overflowing curiosity.
"Eating with friends." Xiao Yunhao shook his head.
"Then what should I do? My parents are not at home, so I can order takeout at home?" Xiao Yingying picked up her feet and leaned back, tilting her head in a threatening tone.
"How about you go with me?" Xiao Yunhao thought for a while and asked.
"Ah? No, then I'll order takeout myself." Xiao Yingying shook her head: "I don't know those friends of yours, so I won't go."
"We know each other, Hai Qing, his girlfriend Liu Bing, Chen Song, and Liu Chi. You've also met them."
"Liu Chi???" Xiao Yingying was stunned for a moment, then said excitedly: "Brother, I saw him last time, but I didn't recognize him. He probably doesn't remember me either."
"When did it happen?" Xiao Yunhao looked at his sister on the sofa suspiciously.
"Years ago, it was midnight. At that time, he was eating by himself, and I even shared the table with him."
"Share a table?" Xiao Yunhao stared at Xiao Yingying with a puzzled look on his face: You have already shared a table and you still don't know her?
You're fooling me.
"Really, it was night, and the restaurant was crowded, so we shared a table together temporarily because there was no room, and the lights were not very bright. I hadn't seen him for a long time, so I didn't recognize him at all."
After Xiao Yingying finished speaking, she added: "I only remembered it after I left."
"What happens after that?"
"There's nothing left to do. They've all left, so I can still chase after him. Besides, I've only met him once, and I'm not very familiar with him." Xiao Yingying shrugged her shoulders.
"You all know what you're afraid of. Go change your clothes quickly."
"..." Half an hour later, the two of them walked out of the house.
Half an hour later, a farm in the suburbs.
Xiao Yingying followed Xiao Yunhao, looking at the ordinary small farm, looking around curiously and said: "Brother, you are eating here, I thought it was some big hotel, club or something like that."
"This place is nice, delicious and affordable. Let's go, they may be here."
Xiao Yunhao added: "By the way, I forgot to tell you just now. There will be a girl who is younger than you later. She came back from studying abroad in Europe. She has a pimple on her face. Please be careful when speaking."
"?"
"Her name is Zhou Meng. She just came back from Europe last night. The injury on her face was caused by an accident in the past and she has not recovered yet."
"Big?"
"Yes, it's very big and long. Be careful when you speak."
"Yeah!" Xiao Yingying nodded.
Go through two corridors.
"Yunhao..."
"Chen Song." Xiao Yunhao waved and said, "You are so fast. Has sister Zhou Meng arrived?"
"We're here, it's up to you now, hurry up." Chen Song glanced at the 'little follower' behind Xiao Yunhao: "Long time no see, Yingying."
"Hello, brother Chen Song, it's only been a few days." Xiao Yingying gave Chen Song a big smile.
"We haven't seen you for a few days, and you look beautiful again." Chen Song flattered her and patted her.
"Brother Chen Song, you are really good at talking. I will introduce you to a beautiful woman later." Xiao Yingying winked at Chen Song.
"I'm just waiting for your words. Don't fool me. I remember it."
"No problem. I'll introduce you to my little sister later. She's so beautiful."
"..."
The three of them chatted for a while, then 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 Yunhao, long time no see." Zhou Meng turned around and stood up after hearing this.
"My sister, Yingying, please meet me." Xiao Yunhao pulled out Xiao Yingying who was following him: "Yingying, this is Zhou Meng, two years younger than you. This is Liu Chi, whom you have met."
"This is Liu Chi's daughter-in-law Ye Yuxin."
"Hello, sister, you are so beautiful." Zhou Meng moved his eyes to Xiao Yingying.
"..."
"Everyone is sitting here, will Chen Song pay the bill this time?" Liu Chi looked at a circle of people standing and chatting, and said hello hurriedly.
"You should be the one footing the bill this time."
"I think Chen Song is footing the bill. There are still 8 more times."
"I'm dizzy..."
"Zhou Meng finally came back, why don't you invite him once?" Li Haiqing made a sharp stab at him.
"Okay, okay, I told you that you are all thinking about me." Chen Song surrendered directly.
"..."
"Liu Chi, how is your motor?" After ordering, Li Haiqing watched a few girls gather together, grabbed a handful of melon seeds from the fruit plate, and asked Liu Chi while eating.
"It's not good yet." Liu Chi shook his head.
"Ring, bell, bell..."
"I'll answer the call first." Liu Chi glanced at the caller, made a quiet gesture, waited for everyone to quiet down, and then pressed the answer button: "Hello..."
"Liu Chi."
"Mr. Zhang?" Liu Chi was stunned and asked suspiciously.
"Are you busy now? You didn't expect me, an old man, to call you."
"It's indeed a bit unexpected. If you have something to do, just ask someone to send a message. You don't need to call me personally." Liu Chi said with a bitter face!
This is probably not a good thing.
Now Mr. Zhang has made the call himself.
I hope it won't be too difficult for a while.
"To be honest, if possible, I really don't want to make this call to you." Mr. Zhang said with a bitter smile.
"What's wrong?" Liu Chi asked doubtfully, "What did you say?"
"I will ask Chen Luguang to give you a piece of information in a moment. You will understand after reading it. Once you get the information, you can reply to me."
"Okay, is the Internet inconvenient?" Liu Chi thought about it and said, "My friends and I are eating out."
"It's not very convenient. In this case, I'll ask Xiao Chen to call you and ask him to send it to you."
"Okay!" Liu Chi nodded and refused.
It’s not convenient to leave now, so today is a ‘big dinner’ for Zhou Meng to celebrate his return to China.
After Liu Chi hung up the phone, he called Chen Luguang's mobile phone directly. After some communication, Liu Chi sent the location.
"What's wrong? Something happened again?" Ye Yuxin knew who Mr. Zhang Liu Chi was talking about. Now that he had called him personally, it was definitely not a trivial matter.
"I don't know yet. It's not convenient to call me on the phone. I won't know what happened until your uncle comes over later." Liu Chi shook his head.
"Yeah!" Ye Yuxin responded.
"..."
One hour later.
Liu Chifang touched his belly and put down the chopsticks in his hand: "I'm full."
"So fast." Chen Song raised his head after hearing this.
"You think everyone is the same as you and can eat like this?" Li Haiqing, who was standing next to him, also put down his chopsticks and said in shock.
"You two can't talk to each other well today. Why are you always quarreling with me?" Chen Song said contemptuously: "I won't die if I don't eat more today."
"No way, who made you owe the debt?" Xiao Yunhao added an assist fiercely.
"Damn, do I deserve to be unlucky?" Chen Song glared at his bad friends with dissatisfaction.
Liu Chi felt the vibration coming from his phone. He picked it up and saw that the message from Chen Luguang had arrived. He said to everyone: "Have you eaten enough? We will leave when you are full."
"What's wrong? Are you busy?"
"Well, my friend is at the door." Liu Chi shrugged helplessly.
"Let's go then. It's close anyway. Let's meet up next time when we have time." Li Haiqing knew that Liu Chi must be busy again, so she said.
"Let's go, let's go."
More than ten minutes later, Liu Chi sent everyone away and asked Ye Yuxin and Zhou Meng to wait nearby, then got into Chen Luguang's car!
"What's going on?" Liu Chi closed the car door and asked Chen Luguang.
"Here is the information. Please take a look at it first to see if there is any 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 waste any time. He opened the seal, took 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 home directly.
It seems that "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 concluded that if the materials could meet the requirements, the success rate would exceed 70%.
The cost exceeds 20 billion, and if losses are included, it will be at least 30 billion.
But fortunately it is not a one-time investment.
Even if we save more, the initial investment will be more than 5 billion, a 1 million-level thermostatic chamber, and a supercomputer cluster!
If the computing power of pseudo-artificial intelligence is used, at least three sets of TaihuLight-level supercomputers will be needed to run it, plus at least four sets of spares.
Upfront investment in materials.
etc......
The core intelligent system is still written by ourselves.
After all, 5 billion may not be enough.
Liu Chi looked at the documents on the electronic screen that listed more than 100 materials and more than 80,000 spare parts, and frowned helplessly.
Package 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 at it now, what the hell is this, so many materials and blanks?" Chen Luguang asked curiously.
"Please check for me and see how many can be processed for me. I have an experiment that I want to use." Liu Chi said rather vaguely.
"Doing experiments? So much? Are you deceiving me? Are you making some equipment?"
"Well, I want to install a set of equipment." Liu Chi changed the topic directly: "Please help me ask the higher-ups, is it possible if I want to buy four 'Taihu Lights'?"
"What? You want to buy four units?" Chen Luguang forgot all about the materials.
"Yes, four stations."
"Is it also for experiments?"
"right......"
"Are you going to heaven and want four sets at once?"
"Please help me ask and let's talk about it later." Liu Chi was also helpless.
"I will report these two things to the superiors, but they may not be successful, especially since you need so much material." Chen Lvguang felt it was necessary to remind him.
"I know. How many are there? Help me sort them out. Don't produce them yet. Mark out the ones that are there for me. I'll figure out the ones that aren't. Of course, it would be best if you could help me."
"Okay, but you have a lot of materials. It will take some time to sort them out. I will let you know when the results are available."
"Okay." Liu Chi nodded and asked, "How is Zhou Meng's matter? Is there any way to cure it?"
"There is hope, but it is not confirmed yet. It will take about two or three days to get the results."
"Okay, let me know when there are results." Liu Chi said happily.
Finally there is good news.
"What I told you two days ago, please give me some snacks." Chen Luguang said.
"I know, I'll give it a try after I finish all the things I'm doing."
"good!"
"..." After Chen Luguang hung up the phone with Liu Chi, he took these materials and went to report to the big boss.
As soon as Liu Chi hung up the phone with Chen Luguang, Jiang Yu called.
"What's wrong with Jiang Yu?"
"Boss, Jiang Dinghong, general manager of Anron Electric, called just now and said that the rice cooker is basically ready. The production line personnel are in place and the launch schedule can be put forward."
“Two and a half million sets of core devices are provided to us at No. 9 Technology every month,” Jiang Yuhui reported.
"You can arrange this. By the way, is the production line of our core equipment in place?"
"It's halfway there, because the rice cooker production line is a bit complicated, and it will take about a month to get it all in place."
"Jiang Dinghong just said that the rice cooker commercial is about to be filmed. He wants to invite Li Xiaoying to ask what your opinion is?"
"Li Xiaoying, she, whatever, I don't have any objections." Speaking of the rice cooker, Liu Chi thought of Yingjiang's Baisi, and asked doubtfully: "Didn't Baisi take away 3.5 million sets of hot water kettles a year ago?
What’s going on now? They haven’t gone public yet?”
"According to the itinerary, it should be in the hands of Bests now, but I don't seem to have seen the relevant information." Jiang Yu finished and added: "Now Bests has placed 5 million additional orders. Starting from May this year, every month
Give them 500,000."
"Starting from May, 2 million sets will be supplied to COFCO, and the remaining 1 million will be taken by Europe's Keck Group. The last 500,000 will be divided among some scattered companies."
"Keck Group is so shameless? How many orders has he placed in total?" Liu Chi asked curiously.
"After placing an order of 3 million, they paid the full amount at once, and the price increased by 10%, which is considered as compensation from the last time." Jiang Yu explained.
"What about the rice cooker? How did Jiang Dinghong arrange it?"
"I didn't participate in the rice cooker thing, but Jingxin Group gets 500,000 yuan a month, and the rest is still being discussed. COFCO also wants a share."
"It's only more than 2.5 million a month. It's too small and not enough to divide." Jiang Yu said helplessly: "There's a lot of quarrel over there, and the tables are being slapped."
"Then ignore them and let them handle it themselves."
"Okay, boss, is the induction cooker also going to be put 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 order from the original Huahong was withdrawn, and the production line is basically automated, the staff is now fully staffed. It was too busy before, but now there is not enough to do."
"Well, let me think about it. You can let Yu Xin come up with the design first."
"Okay, I will communicate with Manager Ye later." Jiang Yu heard Liu Chi relent and said happily.
"..."
After Liu Chi hung up the phone, he could finally turn his attention to the motor.
The last experiment stopped halfway. The motor and bearings had to be manufactured first, otherwise accuracy would be a big problem.
After the motor and bearings are ready, we will have 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 took apart the previous motor.
The balance system needs to be re-corrected and the rotor re-processed.
Magnetic field balancing force.
Only when the balance force of the entire rotor is even, can we still meet our own requirements. There is also the issue of force.
If it is a physical drill bit, when the drill bit hits the blank, a force will be exerted. If it exceeds the working range, the accuracy will change.
The processing accuracy must be high. If it is operated at high speed, friction heat and force problems will occur;
If there is an eccentric force, the value of the centrifugal force is very large at high speed, which means that the work done is useless work;
This wasted work is eventually dissipated in the form of heat, which also requires increased strength of the shaft, so it must be minimized. Therefore, the balance system must have the ability to adjust the balance.
If you want to maintain accuracy.
The motor speed must be increased as much as possible.
According to the formula of centrifugal force and rotational speed: f centripetal force=mrw^2=mv^2/r=mvw=4π^2mr/t^2
g
r is calculated in cm;
The effective centrifugal radius is the length of rotation radius from the motor axis to the bottom of the centrifuge tube 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;
