The texture of the inside of the bearing under the light is completely different from that in the drawing.
Under the reflection of light, the lines inside look like a big snake running, winding and meandering.
This is a bearing;
eldest brother;
What the hell is this twist and turn?
If this accessory is installed, Liu Chi can guarantee that the bearing will break down within three days, without any negotiation.
The entire bearing is the supporting point of the core component of the prism and the control center of the magnetic field. If this thing cannot be made, then there is absolutely nothing to say about the prism and it can just go to sleep in.
You can also go home, take a shower and go to bed.
What are bearings?
Bearings are the most common metal parts in modern industry and life. They are the core components that convert mechanical energy into kinetic energy. No matter what kind of machine it is, they are basically one of the indispensable accessories.
This time, it is the three magnetic field generating points of the entire prism.
Electricity expands the magnetic field!
Electron ionizing magnetic field!!
Atoms induce magnetic fields!!!
Although the requirements for this bearing are a bit too high, there are a total of 36X2=72 positioning grooves of the same size on the front and back and on both sides, and an assembly is installed in each groove.
The front is a little better, all 36 sets of components are consistent and used to fire energy cannons.
The reverse side is a bit more complicated, with 36 slots, each divided into three groups of 12 sets, corresponding to the electric expansion magnetic field, electron ionization magnetic field, and atomic induction magnetic field.
The requirements are very high.
There are 72 sets of components in four groups, which are the core of the entire prism.
In fact, this bearing assembly is also the most difficult accessory of the entire prism.
......
Half an hour later;
Liu Chi took down the bearing that had just been processed from the machine tool, took a deep breath, reached out and picked up a Callander 900x portable microscope from the operating table.
Try again!
Portable microscopes with their own light source are usually used to observe the surface of jewelry and the roughness of the surface of metal materials. They are only the size of a mobile phone and are very suitable for carrying.
Liu Chi adjusted the resolution and light source, and aimed the lens of the portable microscope at the inner hole of the bearing.
After watching for three minutes, Liu Chi put down the bearing in his hand and stretched his tired hands! It would be strange if he didn't feel tired holding an object weighing about 15 kilograms with one hand.
Liu Chi's face also became serious. Under the nine hundred times magnification, it looked crooked just now, but now there were gaps appearing;
These notches are at the edges of each slot.
Like a rat had gnawed it.
Although it is so small that it is difficult to see clearly, it appears crooked when viewed with the naked eye, but one cannot tell where the problem is.
Only under observation with a 900 portable microscope can you clearly see the gaps between the slots.
How thin are these gaps?
When you discover a problem, you have to find a way to solve it. Before solving the problem, you must first find out the root cause of the problem so that you can prescribe the right remedy.
Liu Chi took the bearing to an ultra-high precision laser interferometer for measurement. After some fiddling, he found that the gaps were basically only 0.2UM, so small that they could not be seen with the naked eye.
......
After half an hour of fiddling, observing, measuring, and comparing the results several times, I finally found the answer!
The answer is that the metal material used in this bearing does not meet the requirements.
!!!
Material problem!
well!
Materials are the biggest headache for Liu Chi.
Liu Chi is now feeling overwhelmed, as if he is playing a game. He most hopes to encounter the world boss, but his luck is so good that he encounters him just by chance, and he is blocking his way.
Aaaaahhh!!!
The accuracy problem has been solved;
You have a material problem again.
Is there any love left?
Damn it!!!
Liu Chi almost burst into swearing!
If the material is not solved, there is basically no way to start now. The material just now is already the most suitable for processing bearings;
Still doesn't work.
Now it's completely blocked and I can't move!
......
Liu Chi sighed, put down the measuring tools in his hand, picked up the mobile phone from the table, swiped a few times on the screen, found Wang Shan's number and called it!
“Beep, beep, beep…”
After the phone rang several times, Wang Shanming's full-throated voice came from the phone: "Boss, this is Wang Shan?"
"Manager Wang, do you have any suitable materials for bearings? Do you want the best? Don't worry about the cost." Liu Chi added, "I want something ready-made, or do you have a way to get the best you think?"
“Bearings?”
"Yes, the higher the density, the better. Most importantly, the lower the impurity content, the better. Now I use high-carbon steel and chrome alloy steel, but they don't work. The inside is full of potholes after processing."
"Boss, if those two materials are not good enough, the materials I have now probably won't be much better either?" Wang Shan asked after a while.
"See what you have, or what you can get, and bring some samples over so I can try." At this time, Liu Chi could only try his luck.
"Okay, what specifications do you want, boss?"
"My bearing diameter is 52mm, and the maximum width is 23mm. When you arrange the blank, try to make it larger."
"Okay, I'll arrange it right away and produce it as quickly as possible. I'll also ask some of my friends if they have any suitable ones and we can send them over when the time comes."
"Okay, hurry up with this matter, I'm waiting to use it." Liu Chi instructed.
