Chapter 137 (1/2)
There are four copies of the information.
First copy:
Dahl metal, founded in 1990, is located in wlcb City, Inner Mongolia, covering an area of 1.5 square kilometers and total assets of about 2.5 billion yuan. A medium-sized iron and steel complex mainly engaged in the production of special metals and diversified operation, with 2100 on-the-job employees and about 500 professional and technical personnel
Second copy:
Youbin metal, founded 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 about 1.7 billion yuan. It is a smelting enterprise focusing on steel production, with about 1500 employees
Third copy:
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 a total assets of about 3 billion. It is a metal enterprise mainly producing aluminum materials, with 2500 employees
After reading the three materials in detail, Liu Chi asked Zhu Hongguo, ”can Dar 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 China branch in wlcb city.” Zhu Hongguo just finished, patted his thigh and said, ”it may be difficult for me to talk, but you may be very convenient.”
”You have cooperation with ICBC.”
”OK, I'll ask President Li later.” Liu Chi seemed right when he thought about it.
”Give me other shares. It should be no problem.” Vermilion National Highway: ”do you think Dahl metal is suitable? Are you sure? ”
”For these three companies, Dahl metal is the most suitable.”
”Well, I'll have a detailed investigation of Dahl metal.”
”OK, I'll trouble Mr. Zhu.”
”OK, leave it to me. Although I can't compare with you in invention, acquisition is our old business. It's absolutely no problem.” Zhu Hongguo patted his chest and sealed the ticket.
”...” 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 I really can't move.
Accuracy???
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!
Change of ambient temperature: the solution is very simple. It's OK to build a constant temperature chamber directly.
Motor heating and mechanical friction heating: if the NC 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; This is the material problem.
By directly depicting the balance system on the motor, the rotating shaft can be suspended without any contact, so there will be no friction coefficient.
Now think about it. This force works!
How can we ensure that the rotating shaft does not move during operation.
What if the repulsive force of the magnetic field is added in the middle of the bearing?
？？？
！！！
It seems very feasible.
”Pa...” Liu Chi patted his thigh and stood up excitedly.
No, I have to try;
If you can solve this problem, you really have to go to heaven.
The equipment in the laboratory can fully support yourself to do this experiment.
Excited, Liu Chi left the office directly, came to the laboratory, looked for a computer and began to design the motor directly.
The motor is composed of two basic parts: stator (fixed part) and rotor (rotating part).
The stator is the stationary part of the motor, which is simply composed of shell, winding and base.
......
Directly cancel the winding and install a balance system.
The whole shaft will be suspended!
