There are four copies of the information in total.
First batch:
Daer Metal, 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. It is a medium-sized steel joint venture mainly engaged in the production of special metals and diversified operations. It currently has 2,100 employees and about 500 professional and technical personnel of various types......
Second copy:
Youbin Metal, founded in 1995, is located in the south of JZ City, LN Province, covers an area of 1 square kilometer, with total assets of about 1.7 billion yuan. It is a smelting enterprise mainly engaged in steel production, with about 1,500 employees......
The third:
Chengde Metal, founded in 1985, is located in the south of CD City, Hebei Province, covering an area of 2.5 square meters. The company has total assets of about 3 billion yuan and is a metal enterprise mainly producing aluminum materials. It has 2,500 employees......
After Liu Chi read all three documents in detail, he asked Zhu Hongguo, "Can Dahl Metal be fully acquired?"
"It's not easy. Although it's a private company, 35% of its shares are held by the ICBC branch in WLCB City." Zhu Hongguo just finished speaking, slapped his thigh and said, "It may be difficult for me to negotiate, but it may be convenient for you."
"You have cooperation with ICBC."
"Okay, I'll ask President Li later." Liu Chi thought about it and it seemed to be right.
"I should be able to give the other shares to you." Zhu Hongguo said, "Do you think Dahl Metal is suitable? Are you sure?"
“Among these three companies, Dar Metal is the most suitable.”
"Well, I'll have someone conduct a detailed investigation on Dahl Metal."
"Okay, then I'll trouble you, Mr. Zhu."
"Okay, leave it to me. Although I can't compare with you in inventions, acquisition is our forte, so there will be absolutely no problem." Zhu Hongguo patted his chest and made a promise.
"......" After chatting for half an hour, Zhu Hongguo left happily with the information!

It seems that I have to solve the problem of accuracy first, otherwise it will be stuck and unable to move.
Accuracy???
A ray of light flashed through Liu Chi's mind. As long as he could solve the main reasons that hindered the accuracy of machine tools, wouldn't it be enough?
Changes in ambient temperature: The solution is very simple, just build a constant temperature room.
Heat generated by electric motors and heat generated by mechanical movement friction: If CNC machine tools do not have motors and mechanical friction, wouldn’t that solve the problem?
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.
By engraving the balancing system directly onto the motor, you can completely keep the shaft suspended in the air without any contact, so there will be no friction coefficient.
Now think carefully about the effect of this force!
How can we ensure that the shaft does not move when it is working?
What if we add the repulsive force of a magnetic field in the middle of the bearing?
???
!!!
It seems very feasible.
"Pa..." Liu Chi slapped his thigh and stood up excitedly.
No, I have to try;
If I could solve this problem, I would be very lucky.
The equipment in the laboratory can fully support me to do this experiment.
Excited, Liu Chi left the office and went straight to the laboratory, turned on the computer, and started designing the motor.
The electric motor consists 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 winding and the base.
......
Simply remove the winding and install a balancing system.
The entire shaft will be completely suspended in the air!

11 o'clock at night!
A Dongfeng truck passed by the gate of No. 9 Science and Technology Industrial Park less than ten meters away. With a "puff", the whole side of the truck fell over and knocked down a street lamp directly. It knocked down two street lamps crookedly before it stopped.
"Li Ji, go and see what's going on outside?" Zhou Liang, the team leader on guard duty at the gate of the industrial zone, stood up immediately after hearing the voice, and after looking for a while, he said to the young man not far away.
"It's Captain Zhou." A young security guard ran out.
"Captain Zhou, a Dongfeng truck was in an accident and hit two street lamps, but it looks like no one is hurt. I'll go over and take a look." After saying that, Li Ji opened the electric door and went out.
Two minutes later.
"Captain Zhou, the left front tire of a Dongfeng heavy-duty truck has burst, but no one is hurt." Li Ji's voice came from the walkie-talkie in Zhou Liang's hand.
"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 is any help I can provide." Zhou Liang felt relieved, thinking that at this time these days, there would often be trucks loaded with goods passing by here.
Several cars have passed by just now, so it is normal to have a flat tire.
I guess it's overloaded.
It's really like making money without caring about one's life~~~
"Okay." After receiving Captain Zhou's order, Li Ji asked the middle-aged man who had just finished a phone call, "Hello, is there anything I can help you with?"
"Hello, comrade. I'm sorry to trouble you." The middle-aged man said in a simple manner, "No need. I've already asked someone to help."
"Really not going to use it?" Li Ji glanced at the broken left front wheel.
"Really? That's not necessary. I've asked someone to deliver the tires. It might be a little noisy, but I hope I don't disturb you." The big man rubbed his hands and said embarrassedly.
