The words "Brother Shaoyou" resounded clearly in Chu Ziqiang's head. What an affectionate title!Moreover, one is Qin Shaoyou and the other is Xia Miaomiao, they are definitely not siblings, cousins?It's not like, the way Xia Miaomiao looked at Qin Shaoyou would make Chu Ziqiang jealous.

"Xiaoqiang, you really shouldn't talk nonsense." Wang Xiaobo said: "In our science and engineering department, we believe in data and facts the most."

cockroach?A smile appeared on Qin Shaoyou's face, well, I will forgive you, there is no need to make things difficult for Xiaoqiang.

"Young man, you just said that the rigidity of the linked double pendulum milling head is not enough, can you prove it?"

"It's very simple, just take it apart and take a look. The No. 18 bearing inside has already leaked oil due to excessive force." Qin Shaoyou said.

"Disassemble? It's easy for you to say, do you know the internal structure? What if it can't be installed after disassembly?" Chu Ziqiang retorted again from the side.

In fact, Chu Ziqiang didn't know what the structure was inside, but now, he had to put on a posture, and he must oppose any opinions put forward by Qin Shaoyou, and all Qin Shaoyou's words must be deceitful!

"Hmph, can't you put it back together after you take it apart? Xiaoqiang, are you insulting these people present? Or are you insulting Professor Wang?" Qin Shaoyou deliberately put the word "Xiaoqiang" very seriously, but unfortunately, people in this era don't know What does Xiaoqiang refer to? Tang Bohu ordered Qiuxiang and it hasn't come out yet.

Speaking of multi-axis linkage CNC machine tools, it seems very mysterious. In fact, it is just a few more axes. For ordinary parts, after processing one surface, change the fixture, and then process the other surface, there will be errors. The advantages of multi-axis machine tools , that is, there is no need to change the fixture, and everything can be done in one go.

Among them, the double pendulum milling head is the core component of this kind of processing equipment. It involves many disciplines such as machinery, electricity, hydraulic pressure, and measurement. It is composed of hundreds of parts inside, high rigidity bearings, hydraulic brakes, and multi-bearing support structure…

If you are a layman, you really can't install it after taking it apart, but these people in front of you are obviously studying this kind of device, can they still install it?

"That can't be disassembled. Every time it is disassembled, it will cause wear and tear. These senior brothers have debugged for several months before reaching the current level. If they are disassembled, they have to be re-adjusted. Absolutely not !"

Qin Shaoyou knew that it was impossible for him to ask them to disassemble and repair it with just a few words. After all, he was too young, had no hair on his mouth, and could not do things well.

"It doesn't matter if you don't disassemble it, just change the workpiece. The stainless steel is too hard. Try changing it to an aluminum ingot." Qin Shaoyou said.

This time, Wang Xiaobo also nodded: "Zhao Gang, go to the material department and get an aluminum ingot, and tell me it's what I want."

"Yeah." A student named Zhao Gang ran out quickly, and soon came back with an aluminum ingot.

Without Wang Xiaobo's instructions, Zhao Gang quickly put the aluminum ingot into the CNC machine tool, and after clamping it, closed the plexiglass cover, and then started the system.

The program is still the same as the original program, and the cutter head is still the original cutter head, but this time, the aluminum ingot is cut, which is naturally much easier. With the operation of the cutter, strips of aluminum are cut out, forming a beautiful braid.

After half an hour.

Zhao Gang opened the lid and took out the workpiece inside. When he measured it with a caliper, he immediately exclaimed: "At present, with a vernier caliper with a division of 0.02 mm, there is no error in measuring it, and its accuracy has been improved to 0.01. , Teacher, we succeeded!"

The error was still a few millimeters just now, but now it has been miraculously reduced to less than 0.01, which shows that their CNC machine tool has succeeded!

"Impossible, absolutely impossible, this must be a blind cat hitting a dead mouse! Try again, maybe the error will be big!" Chu Ziqiang shouted.

"Try again? Do you pay? Do you know how much this aluminum ingot costs?" Qin Shaoyou glanced at Chu Ziqiang, his tone full of contempt.

This guy is called Wang Xiaobo as Uncle Wang. It is estimated that his father and mother are also university professors. He is a typical second-generation student. The living conditions are good and he has no concept of money.This piece of aluminum ingot is worth tens of dollars, which is a month's wages as an apprentice!

"Xiaoqiang, as I said just now, you have to believe in data and facts. Now, the facts are in front of you. It is true that the rigidity of the linked double pendulum milling head is not enough. Let's dismantle it!" Wang Xiaobo said.

"Uncle Wang, you can't listen to him, he is a liar!"

"Xiaoqiang, I'm very curious. You have repeatedly prevented disassembly and maintenance. Do you have any ulterior motives? Do you not want this project to succeed? Who are you instigated by? Is this project related to the school? Are there other projects that compete with it?"

"Fart, you spit blood!"

"This is a sacred university, the proud son of heaven, a high-achieving student, how can you speak dirty words? Defiled the sacred campus."

"you!"

Chu Ziqiang blushed and wanted to scold, but, in front of so many people, Wang Xiaobo, Xia Miaomiao... he couldn't say anything, he could only hold back his words.

Pooh!Xia Miaomiao laughed.

The shell of the linkage double pendulum milling head was quickly disassembled, and even without dismantling the internal structure, one of the bearings could be seen, and lubricating oil had leaked out!

"Sure enough, the No. 18 bearing is leaking oil! Qin Gong, you are really amazing!" Zhao Gang cast admiring gazes at Qin Shaoyou.

"Yeah, fortunately, it was discovered early. If it continues to run, other parts will definitely be stained, and the machining accuracy will be worse. Moreover, we still can't find the right direction. Even after graduation, we won't know what the problem is. where!"

These senior students were full of emotions, and their words were full of gratitude to Qin Shaoyou.

Chu Ziqiang was dumbfounded, did Qin Shaoyou really get what he said?No, how would he know?

"Uncle Wang, I see, our machine must have been destroyed by Qin Shaoyou! Otherwise, how would he know what the problem is? Uncle Wang, notify the school security department and arrest Qin Shaoyou! He might be a spy!"

"Okay, that's enough, Xiaoqiang, you don't have anything to do here, you can go." Wang Xiaobo finally couldn't help but started to chase people away.

"What, Uncle Wang, you let me go?" Chu Ziqiang couldn't believe his ears.

"That's right, let's go. When you go back, reflect on your mistakes. To be a human being, you must have a broad mind and a humble attitude. When you do things, you must be careful and meticulous, pay attention to the facts, and don't make false statements."

When Chu Ziqiang left in disgrace, Wang Xiaobo said to Qin Shaoyou: "Qin Gong, thank you for your guidance! By the way, what's the matter with you this time? I still have a little prestige in the school. If you need my help, just tell me. "

"Professor Wang, I did come to ask for help." Qin Shaoyou said: "I have a few complicated parts that I want to process with this machine..."
