Chapter 121: Gravitational Waves Make New Materials
Black Hole Technology Company, No. 3 Machine Tool Factory.
Wei Ming, who participated in the research and development of the high-end machine tool "Phoenix" project, recently encountered a very difficult problem.
High-end machine tools are really hard to build.
Personally, he thinks, it may be more difficult than EUV lithography machines.
Why?
Experience needs to be combined with actual experience.
It is very easy to build a machine tool with an initial processing accuracy of 1 nanometer, Wei Ming and Zhu Guangji have tinkered with it for less than two months, and they have built a prototype machine to process a glass lens, which can ensure the flatness of the surface, and the high and low error is within 1 nanometer.
At that time, Wei Ming thought that the high-end machine tool "Phoenix" had succeeded, it was too easy, and he was about to celebrate.
Zhu Guangji shook his head, and immediately asked the machine tool to process the second lens, and then asked people to measure the error.
"Surface error, 10 nm."
This surprised Wei Ming, "This is only the second piece, why does the error suddenly become so big?" ”
Zhu Guangji and other experts explained to him that unlike lithography machines, 1 nanometer high-precision machine tool does not mean that its processing accuracy has always been 1 nanometer, but that it can achieve 1 nanometer under the best working condition.
"Take the cutting operation of the machine tool as an example, although its cutter head is made of the hardest diamond and sapphire, but in the process of cutting other materials, there will still be wear, which will lead to machining errors, so we have to adjust the processing strength according to the degree of wear, and count a wear formula, dynamically adjust the processing method according to the formula, and achieve the consistency of machining accuracy."
"In addition, in the process of machine tool processing, the motor that drives the cutter head, the motor that drives the mechanical arm, and dozens of motors in the entire machine tool, are working together, so many motors work, the mechanical vibration and parts are loose, and the processing accuracy of the machine tool will be seriously affected for a long time, and even in the case of four-axis and five-axis linkage, it is still possible to achieve good machining accuracy."
"So it is not enough to rely on the machine tool itself to have high precision, and then the precision of the machine tool, you add a strong motor motor to it, and the shock is an ordinary low-end machine tool for half an hour, the most important thing is to use, we must be in the long-term use process, find out its laws, count out the mathematical formula, and finally do it according to the state of the machine tool, process the best parts at any time, this is the birth process of a high-end machine tool."
"This is also a completely empirical discipline, it takes more than five or ten years, constantly summarized, adjusted, and thoroughly understood, in order to completely tame a machine tool, create a peerless artifact, and achieve the degree of 'man-machine integration', in order to process any precision you want."
Wei Ming said before that it would be a fool's dream and whimsical to get the 'Phoenix' high-end machine tool within a year, but Zhu Guangji did not say anything.
Of course, the high-precision parts provided by Weiming are still very important, which can greatly shorten the research and development cycle of machine tools, speed up the progress of taming and understanding, and make it entirely possible to make this project successful within three years.
Wei Ming was dumbfounded.
He didn't expect that there were so many famous names in a machine tool, and he had to face the problem of dynamic wear of the cutter head, and to solve the reduction of accuracy caused by his own mechanical vibration, which was equivalent to embroidering the most perfect flower with a constantly shaking embroidery needle.
The physics and mathematics involved in it, as well as a lot of unspeakable experience, were enough to make his head explode.
He underestimated high-end machine tools.
The difficulty of developing this thing is definitely greater than that of EUV lithography machines - after all, the technical difficulty of machine tools that can be used in the manufacture of lithography machines must be one dimension higher.
What to do?
Is it really necessary to be like Zhu Guangji and other experts said, patience on this project for three years will definitely bear fruit?
The problem is that the second parts factory is in a hurry to need high-end machine tools for manufacturing a large number of high-precision parts to meet the manufacturing needs of the Tyrannosaurus EUV of the first lithography machine factory.
He boasted about Haikou in front of many people, and strives to achieve the mass production goal of shipping at least one Tyrannosaurus EUV per month in 2024.
Now high-end machine tools are not in place.
At least 12 Tyrannosaurus EUV mass production tasks, do they all depend on his god-level polishing?
Does that mean he's going to have an extra year of classes next year?
No way!
This is a no-no!
We must try our best to take down the high-end machine tools and end the boring god-level polishing as soon as possible.
Wei Ming immediately thought of Xiao Hei in his body.
He wants to use Xiao Hei to solve the thorny problems he is currently facing.
"Since the wear of the cutter head will lead to errors, can we find a way to get a material that makes it extremely hard, and in the process of processing other materials, there is almost no wear, and the wear is reduced to zero, and the wear error will disappear?"
"Mechanical vibration can only be reduced, it cannot be avoided, and the machining error caused by mechanical vibration can be reduced by using some high-density materials to increase the quality of the machine tool and improve the shock resistance."
According to these two guiding lines.
Wei Ming intends to create two completely new materials, one wear-resistant and the other high-density.
Then, having the factory's logistics department, buy dozens of tons of crushed coal, stack it in a special workshop, and purchase a large vacuum vessel, began his research.
"Generally, in order to obtain a new material in industry, it is generally necessary to exert more and more pressure and give higher problems in a high-temperature, high-pressure, and interference-free environment, and finally there may be surprises."
"It's called a miracle."
Blackie can also work miracles!
In a high-pressure environment, near the horizon of Xiao Hei, the gravitational pressure brought by the huge gravitational force is equivalent to hundreds of thousands or millions of standard atmospheres.
In a high-temperature environment, the matter moving around Xiao Hei, near the horizon, the matter is accelerated to close to the speed of light, and the particles collide with each other, resulting in high temperatures, not to mention millions or tens of millions of degrees Celsius?
It is entirely possible to trigger nuclear fusion.
About 20 kilograms of pulverized coal are put into the container, and the air in the container is pumped out to make it a vacuum state to avoid the interference of air molecules.
Xiao Hei had already been released into the container.
Slowly expand the gravitational radius.
Let Xiao Hei start to rotate, creating a rotating gravitational vortex, starting from the edge, sucking fine particles of coal dust into the rotating orbit.
Hasten.
Keep lowering the track.
Keep accelerating.
The closer you get to Black's core, the speed is exaggerated.
With the increase of inhaled coal particles, the pressure and temperature near the core also rise sharply.
The collision between high-energy particles produces hundreds of thousands of degrees of high temperature and tens of thousands of standard air pressures.
If it weren't for Wei Ming's full control, nearly half of the high-energy particles would have spilled out, and the other half would have fallen into the field of vision and been completely devoured, and the vacuum vessel would have been destroyed.
But under his precise control, only about one-thousandth of the particles spilled out, and most of them were restrained by Xiao Hei, continuing to pressurize and accelerate...... Wei Ming was sweating all over his head, and his spirit was very exhausted.
More than half an hour later.
Absorbing more than 20 kilograms of coal particles, a high-temperature fireball near the core of Xiao Hei was born, a crystal substance the size of a water droplet was born, it did not melt in the tens of millions of degrees of high temperature, and its structure was stable and unchanged in the violent particle collision.
Wei Ming's spirits lifted!
That's probably what you're looking for!
Immediately weaken the strength of the gravitational radius, or let the little black rotate in the opposite direction, gradually reducing the rotation speed of the droplet crystalline substance.
However, this process is long and slow, and there must be no mistake in between, otherwise the droplet crystals will deorbit at high speed and disappear.
Ten hours later.
In Wei Ming's hand, there was a special crystal substance with a pure transparent color, teardrop-shaped, and a diameter of about 3 millimeters.
It's hard and beautiful in the light.
