Everyone's eyes on Zhou Jingming instantly became different, especially the maintenance workers who were the most unconvinced just now, and they were even more surprised that they couldn't even say anything at this moment.

It's so weird!

Many of them have been repairing cars for more than a year or two, and they think that they have mastered the structure and faults of the car, but who knows, this new college student, just drove a few cars, and the rest didn't even look at it, so he can say the problem of the car so accurately, it is really too clever!

Not only them, Lao Huang also has to be impressed with Zhou Jingming at the moment, I really can't wait to ask Zhou Jingming over immediately, I really don't know how he got such rich on-site experience!

Could it be that he was learning to repair cars in his mother's womb? Or is it that the young man in front of him was born for cars?

Of course, the most surprising thing was Zhao Ke, he was just to test Zhou Jingming at the beginning, and he didn't think that Zhou Jingming could give any substantive conclusions, let alone pin his hopes on him, after all, it has been more than ten years since Shencheng car had such a problem, and no one has been able to solve it until now, how can it be possible to rely on a new college student?

But Zhou Jingming's performance was really beyond Zhao Ke's expectations, not to mention finding out the reason so quickly, a series of follow-up events have proved that every conclusion Zhou Jingming has reached is correct!

This is the most terrifying, anyone can speculate on the reason, but if you can say the reason correctly, then it is really a technical job.

"Now you are a few convinced! Look at your virtue, you know how many catties and taels you have!" Lao Huang did not forget to take this opportunity to teach a few of his workers.

I've been doing it for so many years, and I don't know how my little brother sees it. ”

"College students are college students, and it's really not comparable to us earth dogs. ”

"Little brother, I was offended just now, please don't be surprised!"

Several workers hurriedly said with a smile. Online workers are like this, they don't have any scheming, but they are very simple.

It only took less than an hour for Zhou Jingming to successfully impress the entire maintenance team.

Zhou Jingming naturally didn't care about these people, I saw him come to the dismantled gearbox, pick up a friction plate, put it in his hand and carefully examine it, one end of the friction plate has been seriously burned, and the friction resistance is not enough, which leads to the clutch slippage, and even the final breakdown.

"Is there any problem?" Zhao Ke couldn't help but ask when he saw that Zhou Jingming didn't speak.

Zhou Jingming frowned, and carefully looked at the friction plate in his hand, "The material of the friction plate is asbestos-based, which is manufactured by molding, and there is no problem with the material itself, I guess there is a flaw in the manufacturing process, but I still need further confirmation." ”

Compared with the more expensive powder metallurgy materials and cermet materials, asbestos-based materials are indeed the best choice at present, after all, the load of Shencheng brand cars is not large, and the friction coefficient of asbestos-based is enough to meet the design needs.

When the machinery manufacturing department encounters quality problems, there is such an improvement principle, the first is to find the problem of assembly process, the second is the problem of parts, and finally the problem of design.

There are no special requirements for the assembly of friction plates, so the spearhead of the problem should first point to the parts themselves.

"Manufacturing process? Are you saying that there was a problem with this batch of friction plates from the beginning?" Lao Huang has also been dealing with cars for more than ten years, so he naturally understands what Zhou Jingming means.

"Very likely, Director, is the clutch used in our factory domestically produced or purchased?" The friction plate is only an important part of the clutch, and the clutch that Zhou Jingming has seen before is assembled in the form of an assembly.

Zhao Ke thought for a while, "The main and slave disc parts of the clutch are produced by ourselves, but the friction plate is a purchased part, and the production process of the friction plate is relatively simple, and it is more cost-effective to use the purchased parts." ”

Zhou Jingming was silent, and then put the friction plate in his hand on the ground, "Please work harder, brothers, and disassemble the two gearboxes, I want to confirm whether the friction plate burns out is a common problem." ”

This time, those workers have no complaints, they don't care if you are a college student or not, provided that you have the ability to convince them, Lao Huang and Zhao Ke are naturally qualified to command them, but now, there is a Zhou Jingming to add, in terms of level, Lao Huang is not better than it is impossible to say, but they must not be able to compare.

Since it can't be compared, then it must be right to listen to him.

As soon as a few people greeted them, soon, the gearboxes of the two cars were removed, Zhou Jingming and others stepped forward to take a look, and the friction plates of the two cars were burned to varying degrees!

This time, the problem is obvious, there must be a problem with the friction plate!

"Great! I've finally figured out what the problem is!" Zhao Ke couldn't help but say excitedly.

At yesterday's regular quality meeting, although the factory director Xu Guanglu did not directly name him, Zhao Ke also knew in his heart that the main responsibility for the large-scale breakdown problem of the car lay with him.

Zhao Ke as the youngest workshop director of SAIC Car Factory, the more dazzling the light on his head, the more people will stare at him, and the greater the responsibility to bear.

He was still worried about this matter last night, but he didn't expect it to be solved this morning!

How could he not be excited!

"Xiao Zhou is worthy of being a college student! He has solved our old problems for more than ten years, but he is really our lucky star!" Lao Huang also praised with a smile, revealing a mouth full of yellow teeth.

Compared with the joy of the rest, Zhou Jingming fell into contemplation, he always felt that things were not so simple, there must be something wrong with the friction plate, but what about the others?

For example, in terms of design!

Could it be that the car broke down, and it had nothing to do with the design?

Zhou Jingming frowned, and there was no joy on his face after the problem was solved, "Director, Master Huang, can you take me to see the friction plates that haven't been used yet." ”

"Xiao Chen, you go to the workshop and get a new set of friction plates, move quickly. Zhao Ke quickly gave instructions.

It didn't take long for Xiao Chen to run back out of breath, and what he was holding in his hand was the friction plate that Zhou Jingming wanted.

Zhou Jingming took the friction plate, looked at it carefully, and constantly compared it with the friction plate that had been burned, from the thickness point of view, there is no obvious difference between the new friction plate and the old one, that is to say, the burning of the friction plate is not caused by long-term use.

"It's supposed to be a problem with the manufacturing process. Zhou Jingming raised his head and said.

"Since it's a manufacturing problem, then I'll send someone to the supplier to take a look, if it doesn't work, I'll change the supplier!"

"Wait! I want to take it back and check it first!" Zhou Jingming's eyes lit up, and he suddenly raised his head and said.
