Magic Technology Industry

There are four copies of the information.

first set:

Daar Metal, founded in 1990, is located in WLCB City, Inner Mongolia, covering an area of ​​1.5 square kilometers and total assets of approximately 2.5 billion yuan.A medium-sized iron and steel conglomerate that mainly produces special metals and implements diversified operations. There are currently 2,100 employees and about 500 professional and technical personnel...

Second copy:

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

Third copy:

Chengde Metal, established in 1985, is located in the south of CD City, Hebei Province. It covers an area of ​​2.5 square meters and has total assets of about 3 billion. It is a metal enterprise mainly producing aluminum materials with 2500 employees...

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

"The difficulty is not small. Although it is a private enterprise, 35% of the shares are in the hands of the Industrial and Commercial Bank of WLCB." Zhu Hongguo just finished speaking, patted his thigh and said: "It may be difficult for me to talk, but you may be very convenient. "

"You have cooperation with ICBC."

"Okay, I will ask President Li when I look back." Liu Chi seemed right to think about it.

"Give me the other shares, it should be no problem." Zhu Hongguo said: "Do you think Dahl Metal is suitable? Are you sure?"

"For these three companies, Dahl Metal is the most suitable."

"In this way, I will let Daal Metal conduct a detailed investigation."

"Okay, then I will trouble Mr Zhu."

"Okay, leave it to me, although I can't beat you for making inventions, it's our old business, absolutely no problem." Zhu Hongguo patted his chest and slapped the ticket.

"..." After talking for half an hour, Zhu Hongguo left with the information happily!

......

It seems that I have to solve the problem of accuracy first, otherwise I really get stuck.

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, it was enough!

Changes in ambient temperature: The solution is very simple, just build a constant temperature room directly.

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

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

I directly portray the balance system to the motor by myself, so that the shaft can be suspended without any contact, so that there will be no friction coefficient.

Then think about it now, this force is working!

How can it be ensured that the shaft does not move when it is working?

What if the repulsive force of the magnetic field is added 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 myself to do this experiment.

Excited, Liu Chi left the office directly, went to the laboratory, turned on the computer, and directly started designing the motor.

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

The stator is the stationary part of the motor. Simply put, it is composed of three parts: the shell, the winding and the base.

......

Cancel the winding directly and install a balance system.

The entire shaft will be completely suspended!

......

11 o'clock in the evening!

A large Dongfeng truck passed less than ten meters from the gate of the No. 9 Science and Technology Industrial Park. With a'poof', one side of the vehicle directly knocked down a street lamp, and after knocking down two street lamps slantingly, Just stopped.

"Li Ji, you go and see what's going on outside?" Zhou Liang, the leader of the guard station at the entrance of the industrial zone, heard the voice and immediately stood up. After looking at the probe for a while, he said to the young man not far away.

"It's Team Zhou." A little security guard ran out.

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

Two minutes later.

"Team Zhou, the left front wheel of a Dongfeng heavy truck has a puncture, but there is nothing wrong with it." Li Ji's voice came from the intercom in Zhou Liang's hand.

"Is there something abnormal?"

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

"Ask if there is anything to help." Zhou Liang felt relieved, thinking that these few days are also at this point in time, and trucks full of goods often pass by here.

Several cars have passed, and it is normal for a tire to blow out.

It is estimated to be overloaded.

Really make money without life~~~

"Okay." After receiving the Zhou team's order, Li Ji asked the middle-aged man who had just finished the phone call: "Hello, can I help you?"

"Hello, comrade, I'm sorry, I'm causing you trouble." The middle-aged man said with a plain face: "No, I have asked someone to help."

"No need?" Li Ji glanced at the abandoned front left wheel.

"No, I have already asked someone to send the tires. It might be a bit noisy by then, shouldn't it bother you?" The big man rubbed his hands and looked embarrassed.

"?"

"The air compressor is used for disassembly and assembly, and the sound will be louder." Dahan explained.

"It's okay, you can do it. If you don't need to help, then I will go back first. If there is anything to help, come to the door and call me." Prepare to withdraw later.

"Okay thank you!"

"..."

On a hill not far away.

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

"Give me fifteen minutes."

"Then I will prepare."

"..."

For half an hour, a small white van drove to the truck and stopped.

"Is it Mr. Li?" A middle-aged man with glasses opened the door and walked out of the car.

"Yes, yes, I'm Li Guang, I'm bothering you." The big man greeted him with a happy face when he saw the incoming person.

"It's okay, it's just a car."

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

"It will be a bit noisy when the air compressor is running. You should go and say hello to the industrial area over there." The middle-aged man looked for a while and glanced at the door of the industrial park not far away.

"I already said it just now." The big man added a sentence after he said, "Or I will say it again."

"That's okay, okay, you go and say it again, I'm going to go."

"..."

'Puff puff...' A sound of nearly 100 decibels passed into the night sky from an air compressor.

Two dark shadows climbed over the fence as light as a swallow.

......

'squeak......'

ten minutes later.

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