There are four copies of the information in total.
First copy:
Dal Metal was founded in 1990 and is located in WLCB City, Inner Mongolia. It covers an area of 1.5 square kilometers and has total assets of approximately 2.5 billion yuan. It is a medium-sized steel joint enterprise that mainly produces special metals and implements diversified operations. It currently has on-the-job employees
2,100 people, including about 500 professional and technical personnel of various types...
Second copy:
Youbin Metal, established in 1995, is located in the south of Jz City, Ln Province. It covers an area of 1 square kilometers and has total assets of approximately 1.7 billion yuan. It is a smelting enterprise mainly engaged in steel production and has 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 approximately 3 billion. It is a metal enterprise that mainly produces aluminum materials and has 2,500 employees...
After Liu Chi read all three documents in detail, he asked Zhu Hongguo: "Can Dal Metal acquire it wholly?"
"The difficulty is not small. Although it is a private company, 35% of the shares are in the hands of the ICBC branch in WLCB City." Zhu Hongguo just finished speaking, patted his thigh and said: "It may be difficult for me to negotiate, but it may be convenient for you.
"
"You have cooperation with Industrial and Commercial Bank of China."
"Okay, I'll ask President Li later." Liu Chi seemed right after thinking about it.
"Leave the other shares to me, it should be no problem." Zhu Hongguo said: "Do you think Dal Metal is suitable? Are you sure?"
"Among these three companies, Dal Metal is the most suitable."
"In this case, I will have someone conduct a detailed investigation on Dal Metal."
"Okay, then I'll trouble Mr. Zhu."
"Okay, leave this to me. Although I can't compete with you in invention, acquisition is our old profession, so there is absolutely no problem." Zhu Hongguo patted his chest and confirmed.
"..." After chatting for half an hour, Zhu Hongguo took the information and left happily!
...
It seems that I have to solve the accuracy problem first, otherwise I will be stuck and unable to move.
Accuracy???
A flash of light flashed through Liu Chi's mind. As long as he solves the main reasons that hinder the accuracy of the machine tool, it will be fine!
Changes in ambient temperature: The solution is very simple, just build a constant temperature room.
Motor heat and mechanical motion friction heat: 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 various parts of the machine tool is uneven; this is a material problem.
If you write the balance system directly onto the motor, you can completely make the rotating shaft suspended without any contact, so there will be no friction coefficient.
Then think carefully now, this force works!
How can we ensure that the rotating 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 to be very feasible.
‘Pa…’ Liu Chi slapped his thigh and stood up excitedly.
No, you have to try;
If you can solve this problem, you will really go to heaven.
The equipment in the laboratory can fully support you to conduct this experiment.
Excited, Liu Chi left the office directly, came to the laboratory, turned on the computer, and started designing the motor directly.
The electric 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 consists of three parts: the casing, the windings and the frame.
...
Simply cancel the winding and install a balancing system.
The entire rotating shaft will be completely suspended!
...
11pm!
A large Dongfeng truck passed less than ten meters from the gate of No. 9 Science and Technology Industrial Park. With a 'pop' sound, the entire side of the truck directly knocked down a street lamp. After knocking down two street lamps crookedly,
Then it stopped.
"Li Ji, go check what's going on outside?" Zhou Liang, the captain of the guard station at the entrance of the industrial zone, stood up immediately after hearing the sound. After looking for a while, he said to the young man not far away.
"It's Captain Zhou." A small security guard ran out.
"Team Zhou, a large Dongfeng truck was in an accident and hit two street lights. But it seems that everyone is fine. I'll go over and have a look." After Li Ji said that, he opened the electric door and turned out.
Two minutes later.
"Team Zhou, the left front tire of a Dongfeng heavy truck burst, but the person is fine." 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 yet."
"Ask if there is anything I can help with." Zhou Liang felt relieved, thinking that at this time these days, trucks loaded with goods often pass by.
Several vehicles have passed by just now, and it is normal for a tire to blow out.
It's probably overloaded.
It’s really hard to make money without your life~~~
"Okay." After receiving Team Zhou's order, Li Ji asked the middle-aged man who had just finished the phone call: "Hello, is there anything I can help you with?"
"Hello, comrade, I'm sorry to cause you trouble." The middle-aged man said with a simple face: "No, I have already asked someone to help."
"Really no need?" Li Ji looked at the broken left front wheel.
"No need, I've already asked someone to deliver the tires. It might be a little noisy by then, but I guess it won't disturb you, right?" The big man rubbed his hands and said with an embarrassed look on his face.
"?"
"An air compressor is required for disassembly and assembly, and the sound will be relatively loud." The big man explained.
"It's okay, you can do it. If you don't need help, I'll go back first. If you need help with anything, come and call me at the door." Li Ji looked at it for a while, and after confirming that he didn't need help, he glanced around a few times, but there was no movement.
Then prepare to withdraw.
"OK, thanks!"
"..."
On a hilltop not far away.
"Old A, how are you doing?" Old K looked seriously at the No. 9 Science and Technology Park not far away.
"Give me fifteen minutes."
"Then I'll get ready."
"..."
Half an hour later, a white minivan drove up to the truck and stopped.
"Is this Mr. Li?" A middle-aged man with glasses opened the door and got out of the car.
"Yes, yes, yes, I am Li Guang, please excuse me." The big man saw the person coming and came over with a happy face.
"It's okay, it's just a car."
"Yes, just the left front wheel." The big man pointed at the left front wheel.
"It will be a bit noisy when the air compressor is running. You go and say hello to the industrial park over there first." The middle-aged man looked at it for a while and glanced at the entrance of the industrial park not far away.
"I already said it just now." After the big man finished speaking, he added: "How about I go and say it again."
"Okay, okay, just say it again and I'll be ready."
"..."
‘Puff puff puff...’ A sound of nearly 100 decibels was transmitted from an air compressor into the night sky.
Two black figures climbed over the fence as lightly as swallows.
...
'squeak......'
Ten minutes later.
A hole about half a meter in diameter opened silently.
