How to manufacture a machine tool? Simply put, it means design, production, installation, debugging and acceptance.
Let’s talk about the design first. Now we are copying the German lathe, so we will omit this aspect and just copy it.
And production means making parts, which is a big problem. If you compare a machine tool to a human body, each part is its muscles and bones. Copying the muscles and bones is production. Every part of a German machine tool
In the eyes of these people, it is all "art". The accuracy and stability cannot be compared with Chinese machine tools. To manufacture it, not only the help of machine tools is needed, but also the unique skills of workers, that is, craftsmanship.
There are some parts that cannot be manufactured in China right now because the materials are not up to standard and the precision exceeds the limits of domestic machine tools, so we will put them aside for now.
However, there are some parts that can barely be manufactured using domestic machine tools. The reason why the word "barely" is used is because the manufactured parts only have their appearance but not their charm. For example, a short shaft is made of very small materials.
It's ordinary and doesn't look special, but after it's made, I always feel that the way it rotates is quite different from others.
Why? This is the process involved. People use special methods to control the curve cutting rate when turning the short axis. This is the special process of Andrews Company.
What are the characteristics of Andrews Company's production process? It is very difficult to discover them, even more difficult than Volkswagen Company before. Is it that Andrews Company's process level is higher than that of Volkswagen Company? Of course not.
The parts drawings provided by Volkswagen to Liu Lang were very detailed, with various parameters of the parts recorded in detail on each one. Relying on these parameters, Liu Lang was able to find out the differences of some of the parts, and then deduced the parts.
The craftsmanship relies on Liu Lang's extraordinary computing and statistical abilities. Of course, his knowledge of construction machinery has also reached an "inhuman" level. Without this knowledge, it would be impossible to run a super machine tens of billions of times per second.
Computers can't do what Liu Lang does.
Only when a supercomputer has an algorithm that conforms to certain rules can it select the corresponding conditions according to these rules. Liu Lang, Liu Lang's algorithm with knowledge of mechanical engineering, and a powerful brain can do this like a "super power"
"A general level.
As these machine tools are imported products, manuals are of course indispensable. However, these manuals only have the parameters of the complete machine, and the other party will not give you the parameters of the parts. Without these, Liu Lang seems to be unable to do anything.
However, Liu Lang himself also underestimated his own brain, and some "mutations" occurred in his brain.
After a domestic machine tool is run, as long as there is no quality problem, it will have fixed indicators for operation, such as the speed of the turning tool? Are there any deviations between the parts produced and the standard, and how big is the deviation?
Through these data, we can analyze the consistency and reliability performance standards of machine tools. Students in the School of Mechanical Engineering can do this. In fact, the analysis of these data is completely a mathematical model. As long as it conforms to the model, it can be identified.
Whether the machine tool can be officially put into production is the consistent testing method in the machine tool acceptance stage.
But Liu Lang took a step closer, no, it should be a few steps closer. All the parts of the machine tool were in his mind. He knew all the functions of these parts and knew all the parameters. After the entire machine tool was run, the functions of all parts
The operating image will appear in his mind, forming a dynamic image that is almost like a "God's perspective".
Of course, this image is not really seen, but is completely based on Liu Lang's analysis of various parameters of machine tool parts.
In this case, once a problem occurs in the machine tool, this image will immediately feedback which part has the problem, the engine? Or the spindle? Or a certain short sleeve, or even a certain part, and those non-functional faults
He will also discover the causes of problems such as oil leakage, abnormal noise, slight vibration, safety doors, switches, etc. that do not directly affect the normal operation of the machine tool.
Liu Lang began to have this ability a few months ago, but he didn't tell anyone because it was too "scary".
It may be said that Liu Lang is too familiar with the domestic machine tools that can achieve such a level, but now, these three German machine tools can achieve such a level, even Liu Lang finds it incredible.
Of course, Liu Lang didn't master this "magic skill" in a day or two. He disassembled and reassembled all the parts, and then disassembled them again. A machine tool costing tens of thousands of dollars turned into a pile of building blocks, and everyone else looked at it.
Feeling distressed, this is not over yet. He then processed parts of various materials to test the parameters of each part. Two months later, his ability improved again, and he was able to compare the two machine tools made in China and those made in Germany.
Analyze, and then analyze the part parameters of German machine tools based on domestic parts.
When Liu Lang wrote out the parameters of dozens of parts, everyone present looked at me and I looked at you.
"Liu Lang taught the master of special powers a hard lesson back then. No wonder! He himself is the master of special powers, right?"
A professor thought to himself.
"I think he has clairvoyance and can see every part clearly. This ability is unrivaled!"
Another old teacher secretly said.
In short, Liu Lang is a person with special powers in the eyes of everyone, and all his "abnormal human" behaviors are understandable.
Liu Lang also felt that his abilities were simply miraculous, but after thinking about it, he seemed to be able to understand that he had been reborn once. Even a great person like Einstein didn't know whether he could go to heaven or hell after becoming popular. He only knew
There is no matter in this world that can reach the speed of light, and no one can travel through time, but he alone overturned Einstein's theory.
Being able to be reborn and live again is something that goes against all common sense. If you don't have some ability that can't be explained by common sense, then that's a damn thing.
Maybe his mind is the benefit brought by being reborn, but Liu Lang thinks that this benefit is too low. Look at the reborn protagonists in the novel, which one does not have a golden finger and a powerful system? You can do it with your hands.
If you had the ability to create things out of thin air, how could you still be squatting in the workshop every day and dying of exhaustion like you are now? Just let the system create all kinds of black technology, and then let the countries all over the world bow before you. In the end
Lead mankind to the pinnacle of the universe...!
Of course, these are just Liu Lang's fantasies. He has been reborn for more than five years, and no system has ever appeared to remind him that he still has to rely on himself for everything!
