Siheyuan: The Era of Struggle

Chapter 128 CNC Machine Tool Introduction (Subscription Request)

"What is this?" That day Yang Ning was processing the information sent by various research institutes.

When he picked up a document, he found that it was about a strange-shaped machine tool and its parameters and structure diagram.

Yang Ning picked up the file bag containing the information and took a look. It turned out that the information was sent by his alma mater, the Wudaokou Technical School.

Yang Ning then remembered that when he gave a lecture at the school before, he specifically mentioned the application and development trend of data machine tools.

This document is a CNC machine tool designed by a team of people organized by the school in nearly a year.

Well, just treat it as a CNC machine tool, but this design drawing looks so strange. After calculation, Yang Ning found that although this design drawing looks reasonable, it is actually not reasonable at all.

The locomotive was directly modified using our imitation of Hans' World War II-era machine tool. This was a little better than the X53K1 that was developed a few years later and used an imitation of Big Brother's machine tool, but the arrangement of the servo control system was not reasonable at all.

Looking at the extremely large control room and the complex and confusing wiring, Yang Ning smiled bitterly and shook his head.

"I am a little anxious! If this CNC machine tool is produced, its performance may not even be as good as the historical X53K1."

Yang Ning took a general look at the data and structure of this machine tool. The machine tool can be started, but it seems that there are problems everywhere, and it is very easy to become disordered in control.

In fact, it is not the fault of these teachers and students that they designed it this way. Two years later, when we developed X53K1, although we still had a blank in this regard, at least there were some reference materials and schematic diagrams to learn from.

But we are only in the 56th year now, and the world's first CNC machine tool will not be available on the market until next year. The design of this machine tool depends entirely on the teachers and students' own knowledge and imagination, and it is already remarkable that it can be put into operation.

Yang Ning put the information aside and dealt with other information first.

Yang Ning decided to participate in the development of CNC machine tools.

The reason why he chose to study mechanics in this life was because he didn't want us to follow the old path of history.

Historically, we were the first in Asia to develop CNC machine tools, but we got up early and arrived late.

Even China, which is still recovering from the war, was able to become a powerful country in the production of high-tech equipment. There is no reason why we can't do it!
After get off work, Yang Ning went home to have dinner, said goodbye to Hu Yinghong, then took the drawings and went to the teachers' apartment of Wudaokou Technical School.

"Master's wife, is Professor Dong here?" He went straight to Professor Dong's residence and knocked on the door.

"Yang Ning, why are you here? Have you eaten?"

When Professor Dong’s wife opened the door and saw Yang Ning, she warmly invited him into the house.

After Yang Ning entered the room, he found Professor Dong sitting on the sofa, reading a newspaper.

When he heard it was Yang Ning, he just looked up at him and continued reading the newspaper in his hand.

"I've eaten. Thank you, Master's wife!" Yang Ning took the tea handed over by Master's wife and sat on the sofa in front of Professor Dong. He smiled and said, "Professor Dong, I haven't seen you for a while. You have done a great job, right?"

Professor Dong rolled his eyes at Yang Ning, then glanced at the blueprint on the table. He put down the newspaper in his hand and said unhappily, "Are you here to make fun of an old man like me? Is this design finished? How is it? Is there anything you want to improve?"

As a professor at the School of Mechanical Engineering of China Wudaokou Technical School, Professor Dong naturally participated in the design of this CNC machine tool, so after seeing the drawings, he asked three questions in a row.

Yang Ning looked at Professor Dong, who looked much older than when he just graduated. He couldn't bear to criticize him, so he could only say tactfully: "Many designs are very innovative. For example, the servo control system is the first of its kind in China..." "Don't say these useless things. Just tell me whether the design of this machine is feasible or not?"

Professor Dong glared at Yang Ning and said, "What you said is nonsense. This is the first machine tool we designed. It is slightly different from traditional machine tools and is a domestic first."

But from Yang Ning's expression, Professor Dong saw that there was something wrong with this design.

He had no doubt about Yang Ning's calculation ability. Moreover, mechanics was Yang Ning's major and Yang Ning's professional foundation was also extremely solid.

Any slight problem in the design of a CNC machine tool will not escape Yang Ning's eyes.

"Well, there are still some problems with the machine tool built using the design on this drawing." Yang Ning answered honestly.

"What went wrong? I calculated it later, so there shouldn't be any problem with the machine tool equipment, right?"

"There are no major problems in this area. The main problems are in the hydraulic system, control system and wiring layout."

"It's not a big problem, but there are still some issues. Tell me about it." Professor Dong said unconvincedly when he heard Yang Ning say that.

"Well, generally speaking, there is no problem. But in the design of the machine tool, did you fail to take into account the electromagnetic interference factors of the external environment? After all, the working environment of the machine tool is very sensitive."

Looking at this unconvinced old man, Yang Ning simply pointed out the mechanical problems.

"Also, the sealing system data of the hydraulic system is incorrect. When the power element reaches a certain power, the hydraulic system will leak oil, so the power of the actuator cannot meet the design requirements at all."

"Hiss!" After hearing Yang Ning's words, Professor Dong quickly picked up the design drawing and started looking at it. Then he couldn't help but take a breath.

"That's true. Traditional machine tools don't need to consider these things. After all, they mainly rely on the workers' craftsmanship."

"I am still calculating according to traditional machine tools!"

"Wait here, don't leave yet, I'll go call someone!" After saying that, Professor Dong put down the drawings and ran out in a hurry.

Yang Ning looked at Professor Dong in silence as he hurried along. If one didn't know better, one would have thought that he was going to ask someone to help him.

"It's already this late, what are you still doing?"

"Slow down~"

At this time, the teacher's wife came out with a plate of fruit. Seeing Professor Dong running out in a hurry, she shouted anxiously.

"This old man!" Seeing that Professor Dong had run away, the teacher's wife cursed at the door with a smile, and then smiled embarrassedly at Yang Ning who was sitting next to her.

After a while, Professor Dong came back in a hurry with three people.

Yang Ning also knew one of them, who was the dean of the School of Mechanical Engineering when he was studying. After Professor Dong’s introduction, Yang Ning learned that the other two were both professors of the Department of Electrical Engineering. The woman in her thirties was Professor Xia, who was later called the "Mother of Computers."

　I'm going to the train station later. There are only two chapters today. The remaining chapter will come later, before 8 o'clock in the evening. Please forgive me!
