Chapter 241 (1/2)
The inner part of the bearing, under the light, presents the texture, which is not shown on the drawing.
Under the reflection of light, the lines inside are like big snakes running, winding.
This is a bearing;
eldest brother;
What the hell is bending;
If this part is installed, Liu Chi can guarantee that the bearing will stop cooking in less than three days without discussion.
The whole bearing is the support point of the core component of the prism and the magnetic field control center. If these things can't be made, there's absolutely nothing to say about the prism. You can go to the side and sleep in slowly.
You can also go home and wash and sleep.
What is the bearing?
Bearing is the most common metal part in modern industry and life. It is a core component that converts mechanical energy into kinetic energy. No matter what machinery it is, it is basically one of the indispensable accessories.
This time, it is the three magnetic fields of the whole prism.
Power expands the magnetic field!
Electron free magnetic field!!
Atomic induced magnetic field!!!
Although the requirements of this bearing are too high, there are 36x2 = 72 detent grooves with the size of one to on both sides, and each groove is equipped with an assembly.
The front is a little better. 36 sets of assemblies are one to one, which are used to launch energy guns.
The reverse side is a little complicated. There are 36 detents, one of which is divided into three groups, each of which is 12 sets, corresponding to electric expansion magnetic field, electron free magnetic field and atomic induction magnetic field.
Very demanding.
There are 72 sets of assemblies and four groups, which are the core of the whole prism.
In fact, this bearing assembly is also the most difficult part of the whole prism.
......
Half an hour later;
Liu Chi took down the newly machined bearing from the machine tool. With a deep breath, he reached out from the console and picked up a Kaland 900 times portable microscope.
do it again!
A portable microscope with its own light source is usually used to observe the surface roughness of jewelry and metal materials. It is only the size of a mobile phone and is very suitable for carrying.
Liu Chi adjusted the resolution and light source, and aligned the lens of the portable microscope with the inner hole of the bearing.
After watching for three minutes, Liu Chi put down the bearing in his hand and moved his tired hands! It's strange to hold an object of about 15 kilograms in one hand without getting tired.
Liu Chi's face also became serious. Under 900 times magnification, it looked like twists and turns just now, but now I can still see gaps;
These notches are at the edge of each slot.
It's like a mouse.
Although it is so small that people can't see clearly, it can feel tortuous with the naked eye, but we can't see the problem.
Under the observation of 900 portable microscope, we can see that there are gaps between the slots.
How thin are these gaps?
If you find a problem, you have to find a solution. Before solving the problem, you have to find out the root cause of the problem before you can apply the medicine to the case.
Liu Chi took the bearing to an ultra-high precision laser interferometer for measurement. After some manipulation, the gap was basically only 0.2um, which was too thin to be seen with the naked eye.
......
After half an hour of fiddling, observation and measurement, after several results comparison, we finally found the answer!
The answer is that the metal material used in this bearing can not meet the requirements.
！！！
Material problem!
Alas!
Material is the biggest headache for Liu Chi.
Liu Chi now feels that the first two are big. He feels like playing a game. He most hopes to meet the world boss, but you are so lucky that you encounter it and directly block your way forward.
Ah ah!!!
The problem of accuracy is solved;
You come to the material problem again
There is no love.
Shit, shit!!!
Liu Chi almost burst into foul language!
If the material is not solved, there is basically no way to start now. The material just now is the most suitable for processing Bearings;
Still not.
It's completely blocked now!
......
Liu Chi sighed, put down his measuring tools, picked up his mobile phone from the table, scratched a few on the screen, turned out Wang Shan's number and called out!
”Doo, Doo, Doo...”
After the bell rang several times, Wang Shanming's hearty voice came from his mobile phone: ”boss, I'm Wang Shan?”
”Manager Wang, do you have any suitable materials for bearings? Do you want the best? Cost doesn't matter. ” Liu Chi added, ”I want ready-made, or you have a way to get what you think is the best.”
”Do bearings?”
”Yes, the higher the density, the better. The most important thing is that the lower the content of sundries, the better. Now I can't use high carbon steel or chromium alloy steel. There are potholes inside.”
”Boss, if those two materials are not good, I don't think the materials in my hand are much better now?” Wang Shan asked after a while.
”See what you have in your hand, or what you can get. Get some samples and I'll try.” At this time, Liu Chi could only be a living horse doctor.
”OK, what's the specification the boss wants?”
”My bearing diameter is 52mm, the maximum is 23mm. When you arrange the blank parts, try to be larger.”
”OK, I'll arrange it immediately and produce it as soon as possible. I'll also ask some of my friends to see if they have suitable ones and send them together at that time.”
”OK, hurry up. I'll use it later.” Liu Chi explained.
”OK.”
”Do you have all the scientific researchers in place now?” Liu Chi asked.
”Not yet. Recently, I recruited a group of fresh students from colleges and universities across the country. Some of them are not in place. In another month, the scientific research system will be basically built. If you want to form combat effectiveness, it is estimated that it will take more than a month to run in.”
“......”
After 10 minutes, Liu Chi hung up the phone, put down his mobile phone and tried again when Wang Shan sent some materials.
After that, I called Chen Luguang and asked him to help!
If not, we can only start with the materials.
In fact, the material problem is the last thing Liu Chi wants to touch.
I feel like buying lottery tickets. If I'm lucky, I won at once. If I'm not lucky, ten or eight years will be in vain.
Study it again.
Liu Chi thought for a long time and thought that a diamond grinding layer with a thickness of only a few nanometers could be plated by plasma vapor deposition.
But he gave up before he started.
Because it's more unreliable!
Because I don't have that technology, I can't do it myself. Even one of those domestic Seiko enterprises can do it;
To have such a technology, there is also a series of technologies. Liu Chi now feels that he is as busy as a dog. If he develops a series of technologies, he will not let people live. There is no time to do it again.
Let's talk about this later. There's no air control over it now.
