There are four copies of the information.

First Serving:

Dahlmetal, founded in 1990, is located in WLCB City, Inner Mongolia, covering an area of 1.5 square kilometers and with total assets of about 2.5 billion yuan. A medium-sized iron and steel conglomerate mainly engaged in the production of special metals and diversified operations, with 2,100 employees and about 500 professional and technical personnel......

Second Serving:

Youbin Metal, established in 1995, is located in the south of JZ City, LN Province, covering an area of 1 square kilometer, with total assets of about 1.7 billion yuan, is a smelting enterprise mainly engaged in steel production, with about 1,500 employees......

3rd Serving:

Chengde Metal, founded in 1985, is located in the south of CD City, Hebei Province, covers an area of 2.5 square meters, with total assets of about 3 billion, is a metal enterprise mainly producing aluminum, with 2,500 employees......

After reading all three documents in detail, Liu Chi asked Zhu Hongguo: "Can Dalmetal be wholly acquired?"

"Although it is a private company, it also has 35% of the shares in the hands of the ICBC branch in WLCB City. As soon as Zhu Hongguo finished speaking, he patted his thigh and said, "It may be difficult for me to talk, but it may be convenient for you." ”

"You have a cooperation with ICBC. ”

"Okay, I'll ask Governor Li when I go back. Liu Chi seemed right when he thought about it.

"Give me the other shares, it should be fine. Zhu Hongguo said: "Do you think Dalmetal is suitable?"

"With these three companies, Dalmetal is the best fit. ”

"In that case, I'll have Dalmetal investigated in detail. ”

"Okay, then it's troublesome Mr. Zhu. ”

"Okay, leave this matter to me, although I can't compare to you when it comes to invention, the acquisition is our old business, absolutely no problem." Zhu Hongguo patted his chest and hit the ticket.

......After chatting for half an hour, Zhu Hongguo left with the information!

......

It seems that I have to solve the problem of accuracy first, otherwise I will really be stuck and unable to move.

Precision???

A ray of light flashed in Liu Chi's mind, as long as he solved the main reasons that hindered the accuracy of the machine tool!

Changes in ambient temperature: The solution is very simple, just build a constant temperature room and it's OK.

Motor heating and mechanical motion friction heating: If the CNC machine tool does not have motor and mechanical friction, it will be solved.

As for the influence of cutting heat and cooling medium, the temperature rise of each part of the machine tool is uneven, which is a material problem.

By portraying the balance system directly to the motor, you can completely make the shaft suspended without any contact, so that there will be no friction coefficient.

Now you have to think about it, this force works!

How can we ensure that the shaft does not move when working.

What if you add the repulsion of a magnetic field to the middle of the bearing?

？？？

！！！

It seems that the feasibility is very high.

'Smack...' Liu Chi slapped his thigh and stood up excitedly.

No, you have to try;

If you can solve this problem, then you really have to go to heaven.

The equipment in the laboratory can fully support you to do this experiment.

Liu Chi, who was excited, left the office directly, came to the laboratory, turned on the computer, and directly began to design the motor.

The motor is composed of two basic parts: the stator (fixed part) and the rotor (the rotating part).

The stator is the stationary part of the motor, which is simply composed of three parts: shell, winding and base.

......

Directly cancel the windings and install a balance system.

The whole reel will be completely suspended in the air!

......

11 p.m.!

A Dongfeng truck, less than ten meters from the gate of No. 9 Science and Technology Industrial Park, 'poof', the entire side of the car, directly knocked down a street lamp, crookedly knocked down the two street lights, and then stopped.

"Li Ji, can you go and see what's going on outside?" Zhou Liang, the captain of the guard detachment at the entrance of the industrial zone, immediately stood up after hearing the voice, and after looking at it for a while, he said to the young man not far from the side.

"It's Team Zhou. A small security guard staggered out.

"Team Zhou, it was a Dongfeng truck that had an accident and hit two or two street lights, but it seems that people are fine, I'll go over and take a look. After Li Ji finished speaking, he opened the electric door and turned out.

Two minutes later.

"Team Zhou, the left front wheel of a Dongfeng heavy truck had a flat tire, but there was nothing wrong with the person. Li Ji's voice came from the walkie-talkie in Zhou Liang's hand.

"Is there anything unusual?"

"It should be a normal accident. Li Ji looked around, and then said, "I haven't seen anything special for the time being." ”

"Ask if there's anything you can help with. Zhou Liang felt relieved, thinking that these days are also at this point in time, and trucks full of goods often pass by.

It's been several past just now, and it's normal to blow a tire.

It is estimated that it is overloaded.

It's really hard to make money~~~

"Okay. After receiving Team Zhou's order, Li Ji asked the middle-aged man who had just finished the call, "Hello, is there anything I can do to help?"

"Hello comrade, I'm sorry to cause you trouble. The middle-aged man said with a simple face: "No need, I have already called someone to help." ”

"Really?" said Leeki, glancing at the discarded left front wheel.

"I really don't need to, I've already asked someone to send tires, it might be a little noisy at that time, it shouldn't bother you, right?" the big man rubbed his hands and said with an embarrassed expression.

“？”

"If you need to use an air compressor for disassembly and assembly, the sound will be louder. Dahan explained.

"It's okay, you can get it, you don't need to help, then I'll go back first, if there is anything to help, come to the door and call me." Li Ji looked at it for a while, and after confirming that he didn't need help, he glanced at the neighborhood a few times, and then prepared to withdraw after there was no movement.

"Okay, thank you!"

“......”

On a hill not far away.

"Old A, how is it?" Old K looked at the No. 9 Science and Technology Park not far away.

"Give me fifteen minutes. ”

"Then I'll prepare. ”

“......”

Half an hour later, a small white van pulled up to the truck and stopped.

"Is that Mr. Li?" a middle-aged man with glasses opened the car door and stepped out of the car.

"Yes, yes, I'm Li Guang, I'm sorry for you. When Dahan saw the comer, he greeted him with a happy face.

"It's okay, it's just the car. ”

"Yes, the left front wheel. The big man pointed to the left front wheel.

"It's going to be a bit noisy when the air compressor is running, so you go and say hello to the industrial area over there. The middle-aged man looked at it for a while and glanced at the entrance of the industrial park not far away.

"I just said that. After speaking, Dahan added: "Or I'll say it again." ”

"Alright, alright, you go talk again, I'm ready. ”

“......”

'Puff puff puff ......' a nearly 100-decibel sound came from an air compressor into the night sky.

Two black shadows climbed over the fence as light as swallows.

......

'Squeak' ......

Ten minutes later.

A hole almost half a meter in diameter burst open silently.
