Magic Technology Industry

"Okay." Liu Chi nodded and didn't care, and continued with the question just now: "The smelting plant will be purchased in about a month."

"Now I have a motor and bearing for ultra-high-precision machine tools. The first test product has been released. If it is normal, 1UM precision CNC machine tools can be built by then."

"The accuracy of 1UM seems to be not enough. If it is 0.5UM, it is almost the same."

"The domestic limit accuracy is now about 3UM." Liu Chi rolled his eyes: "You girl thinks this is Europe."

"In fact, what I am most worried about is the tool. If there is not a strong enough tool, it will be very troublesome." Liu Chi said helplessly: "You should also be aware of the defects of this system."

"Relax, I have a plan to be used." Zhou Meng pointed to the screen and said, "You minimize it first."

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

"Go back again."

"Back again."

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

"Three knives linkage?" Liu Chi opened the folder a little puzzled.

A design drawing of the three-tool system appeared on the screen. After a while, Liu Chi asked, "How do you adjust the accuracy of the three-tool linkage?"

"Look here, there are detailed instructions."

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

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

"Well, I can't refute it. Now the main issue 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 ourselves, it may exceed 1UM."

"I have handed it over to the three of them about the ultra-high precision machine tool."

"Can it work to reach 1UM?"

"should be no problem."

"..."

A certain cell.

"Yingying, I won't eat at home tonight."

"Brother? Are you going on a date?" Xiao Yingying shifted her gaze from the TV and looked at Xiao Yunhao, who was well dressed, with curiosity bursting.

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

"Then what should I do, my parents are not at home, so I order takeaway at home?" Xiao Yingying lifted her feet up and leaned back, tilting her head in a deadly tone.

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

"Ah? Don't let it go, then I'll order takeaway myself." Xiao Yingying shook her head: "I don't know your friends, so I won't go."

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

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

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

"Years ago, it was midnight, when he ate by himself, and I had a table with him."

"Fighting tables?" Xiao Yunhao stared at Xiao Yingying suspiciously, with a word on his face: You have joined tables, don't you know?

Fudge me.

"Really, it was at night. There were so many people in that restaurant, so I had to put together tables temporarily, and the lights were not very bright. I didn't see them for a long time, so I didn't recognize them."

After Xiao Yingying finished speaking, she added: "I only remembered it after I left."

"And after that?"

"It's no more, everyone is gone, I can still chase him there, besides, I only met him once, and I am not very familiar. Xiao Yingying shrugged.

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

"..." After half an hour, the two walked out of the house.

Half an hour later, a farm in the suburbs.

Xiao Yingying followed Xiao Yunhao and looked at the ordinary small farm. She looked around curiously and said, "Brother, you guys are eating here. Why do you think it is a big hotel, a clubhouse, etc."

"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 that there will be a girl who is younger than you. He came back from studying at the X Bridge in Europe. There is a stick on her face, and she will speak carefully."

"?"

"Her name is Zhou Meng. She only came back from Europe last night. The wound on her face was caused by an accident before, and she is still ill."

"It's huge?"

"Yes, it's a big, long one. Be careful when you speak."

"Yeah!" Xiao Yingying nodded.

Go through two corridors.

"Yunhao..."

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

"I'm here, I'll leave you now, hurry up." Chen Song glanced at the'little chase' behind Xiao Yunhao: "Yingying hasn't seen you for a long time."

"Brother Chen Song is good, it only took a few days." Xiao Yingying gave Chen Song a big smile.

"I haven't seen him in a few days, and he looks pretty again." Chen Song flattered him.

"Brother Chen Song, you really can talk, turn around and introduce you to a beautiful woman." Xiao Yingying winked 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, she looks pretty."

"..."

The three chatted for a while, walked a turn, 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 when he heard the words and stood up.

"My sister, Yingying, get acquainted." Xiao Yunhao pulled out with Xiao Yingying behind her: "Yingying is Zhou Meng, two years younger than you. This is Liu Chi, you have seen her."

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

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

"..."

"Sit all sit down, is Chen Song paying the bill this time?" Liu Chi greeted as he watched a group of people standing and chatting.

"You should pay the bill this time."

"I think Chen Song paid the bill, and there are 8 more times."

"I'm dizzy..."

"Zhou Meng finally came back, won't you please?" Li Haiqing made a sharp cut.

"Fine, I said you guys are thinking of me all the time." Chen Song directly surrendered.

"..."

"Liu Chi, how is your motor?" After ordering the dishes, Li Haiqing watched the girls get a piece, grabbed a handful of melon seeds from the fruit plate, and asked Liu Chi while nibbling.

"It's not good yet." Liu Chi shook his head.

"Ling, Ling, Ling..."

"I'll take the call first." Liu Chi glanced at the call, made a quiet gesture, waited for the crowd to calm down, and answered the answer button: "Hey..."

"Liu Chi."

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

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

"It's really a bit surprising. If you always have something, just ask someone to send a message, you don't need to call me in person." Liu Chi said bitterly!

This is probably not a good thing.

Now I asked Mr. Zhang to call himself.

Hope it won't be too difficult for a while.

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

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

"I will ask Chen Luguang to give you a copy of the information in a while. You will understand when you look at it. Once you have the information, please 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, so I will let Xiao Chen call you and ask him to send it to you."

"Okay!" Liu Chi nodded and refused.

It is not convenient to leave now. Today is a'feast' for Zhou Meng to celebrate his return to China.

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 wrong, something is going on again?" Ye Yuxin knew who Liu Chi was talking about Lao Zhang, and now his elders have personally called, it must be no small matter.

"I don't know yet. It's not convenient to say on the phone. I won't know what happened until your uncle comes over." Liu Chi shook his head.

"Yeah!" Ye Yuxin responded.

"..."

after an hour.

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

"So fast." Chen Song raised his head upon hearing the words.

"You think everyone is the same as you, so they can eat this way." Li Haiqing also put his chopsticks on the side, and said in a shock.

"Today you two can't talk well, so it's okay to frustrate me." Chen Song despised: "I don't eat more today, I won't lose money."

"No way, who makes you owe you." Xiao Yunhao made up an assist fiercely.

"Damn, I deserve to be unlucky?" Chen Song stared at a few hurt friends dissatisfied.

Liu Chi felt the vibration coming from the mobile phone. He picked it up and took a look. The message from Chen Luguang had arrived. He said to the people, "If you are full, you will withdraw."

"What's wrong, busy?"

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

"Let's go, anyway, get together again when you have time." Li Haiqing knew that Liu Chi must be busy again, so he said.

"Walk around."

After more than ten minutes, Liu Chi sent everyone away, leaving Ye Yuxin and Zhou Meng to wait for a while and got into Chen Luguang's car!

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

"This is the information you need to look at first. Is there 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 talk nonsense, opened the seal, pulled out the document, and opened the first page.

Title: "21 HNA Project"

After half an hour, Liu Chi got out of the car with a headache, beckoned 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 meet the requirements, the success rate will exceed 70%.

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

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 power of pseudo artificial intelligence is used, at least three sets of Taihu Light-level supercomputers are required to run, plus at least four sets of spare ones.

Early-stage investment in materials.

and many more......

The core intelligent system was written by myself.

After calculating the whole set, 5 billion may not be enough.

Liu Chi looked at the documents on the electronic screen with more than 100 materials and more than 80,000 parts blanks, helplessly frowning.

Pack up the files and send them to Chen Luguang.

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

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

"You help me check how many can be processed for me, I have an experiment to use." Liu Chi said vaguely.

"Experiment? So much? Are you fooling me? Are you making some equipment?"

"Well, I want to equip one set of equipment." Liu Chi changed the subject directly: "Help me ask the above, can I buy four Taihu Lights?"

"Huh? Are you going to buy four?" Chen Luguang lost everything about materials.

"Yes, four stations."

"Also for experiment?"

"Correct......"

"You are going to heaven, four at a time?"

"You help me ask, let's talk about success or not." Liu Chi was also helpless.

"I will report these two things to the above, but they may not happen, especially if you need so much material." Chen Luguang felt that there was a need to remind.

"I know that counts as much as there are. Help me sort out. Don't produce them first. If there are ones, mark them for me. If there are none, I think of a solution by myself. Of course, it's best if you can help me."

"Okay, but you have a lot of material. You have to sort it out in a few moments. I will let you know when there are results."

"Okay." Liu Chi nodded and asked, "What happened to Zhou Meng? Is there a way to cure it?"

"There is hope, but it hasn't been determined yet. We will have to wait two or three days for results."

"Okay, let me know if there are results." 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 have dealt with everything at hand, I will try it."

"it is good!"

"..." After Chen Luguang hung up Liu Chi's phone, he took the materials and reported to the boss.

When Liu Chi just hung up the phone with Chen Luguang, Jiang Yu called.

"Is there anything wrong with Jiang Yu?"

"Boss, Jiang Dinghong, general manager of Anran Electric, just called and said about the rice cooker. Basically, preparations are almost complete. The production line personnel are already in place and the listing schedule can be brought up."

"Every month 2.5 million sets of core devices are given to our No. 9 Technology." Jiang Yuhui reported.

"You can arrange this, right? Is the production line of our core device in place?"

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

"Just now Jiang Dinghong said that the commercial for the rice cooker is ready to be filmed. He would like to invite Li Xiaoying to ask if you have any comments?"

"Li Xiaoying, she, whatever, I don’t have any opinion." When it comes to rice cookers, Liu Chi thinks of Yingjiang’s Best, and then asks quizzically: “A year ago, Best had taken 3.5 million hot water bottles. What? How are they? They haven't listed yet?"

“According to the itinerary, it should be in Best’s hands now, but I don’t seem to see the relevant information.” Jiang Yu added another sentence after finishing his sentence: “Now Best Plus has placed 5 million orders, starting from May this year, every month Give them half a million."

"Starting in May, COFCO will supply 2 million sets. For the remaining 1 million, the Keck Group in Europe won 500,000, and the final 500,000 will be divided among some scattered companies."

"Keck Group has such a thick skin? How many orders has he placed in total." Liu Chi asked curiously.

"After paying 3 million, they paid the full amount at once, and the price rose by ten percent, which is considered the last compensation." Jiang Yu explained.

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

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

"Only more than 2.5 million a month, the amount is too small, not enough points." Jiang Yu helplessly said: "It's noisy over there, the table is not too much."

"Then ignore them, let them handle it by themselves."

"Okay, is the boss's induction cooker also on the agenda?" Jiang Yu said a little greedy: "After all, the company still has so many vacant factories, and the rice cooker only used two factories."

"Since the original Huahong order has been returned, plus it is basically an automated production line, the staff is now very sufficient. I was too busy before, and now there is not enough work."

"Well, let me think about it. You can let Yuxin get the design drawings first."

"Okay, I will communicate with Manager Ye in a while." Jiang Yu heard Liu Chi song mouth happily.

"..."

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

The last experiment was halfway down, and it stopped, and the motor and bearing had to be manufactured first, otherwise the accuracy would be a big problem.

Only when the motor and bearings are ready, will there be time to deal with what Zhang Lao said.

The "Automatic Design System" can't move even if the motor doesn't come out.

The last time the error was 0.5 grams 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 needs to be revised and the rotor reworked.

Magnetic field balance force.

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

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

The machining accuracy should be high. If it is at high speed, it will cause frictional heat and force problems;

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

This wasteful work is finally dissipated in the form of heat, and there is also an increased requirement for the strength of the shaft, so it should be minimized, so the balance system must have the ability to adjust the balance.

If you want to maintain accuracy.

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

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

g=r×11.18×10-6×(rpm)2

r is calculated in cm;

The effective centrifugal radius is the length of rotation radius from the motor shaft center to the bottom of the centrifuge tube.

Conversion of revolutions and 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;
