"There is another very important point you need to know, do you look at this drawing, the benchmark symbol on it? The clamping part of our machine is actually the benchmark, and our clamping jaw is the indirect benchmark of the workpiece! ”

"If the claws are clean, the benchmark for clamping every part is guaranteed to be the same! If one part is clamped with iron cutting, and another part cannot carry the same iron filings when clamping, then the benchmark will change! Parts that are not machined on the same basis obviously have problems when they are machined together! ”

"Even the parts processed by different machine tools will have shape and position errors, so there are so many things, we should try to avoid human deviation when processing products, understand?"

Looking at a few students coming around, Ji Donglai simply began to explain this matter, Li Chunhe also listened attentively beside him, and a group of students kept nodding.

Scattered again, many students began to take notes, and the class leader even directly sent a student to take the initiative to clean the surface of the semi-finished product.

Carefully check every item on the drawing, especially with regard to the position of the datum.

"Young man, your craft is real! It's really good, few people can understand the machine so thoroughly, the vast majority of practitioners in this industry are mixed, in my old man's words, anyone who has a little ability is not doing a grease twist profession, dirty and tired! You're here to ......."

The cigarette butt in his hand was extinguished and put in his pocket, Li Chunhe looked at Ji Donglai, with a sincere face, and Ji Donglai smiled.

"It's not about it, it's just to make some money to support the family! People are divided into high and low, regardless of occupation, this industry is all based on craftsmanship! In fact, all of them are, Master Li's side Mr. Lu does not allow outsiders to enter, if you have something, you tell me to go out and talk about it! ”

Regarding Li Chunhe's compliment, Ji Donglai was not cold.

Especially the other party's uninvited visit, Ji Donglai doesn't like it even more.

Because just yesterday, when Ji Donglai came to trial production, he found that there was a problem with the workpiece, and at first Ji Donglai thought it was the lack of experience on the student's side.

I ended up getting one myself, and it was crooked to check it. Ji Donglai hurriedly checked the machine tool, and found that the spindle of the machine tool was offset by 0.5 degrees, and it was not an insider who could not see it at all.

Even if you are an insider, it is difficult to spot if you are not very careful.

Ji Donglai checked all the machine tools on his side by the way, and all of them were in this situation without exception. This proves that it is definitely not the machine itself, and it is likely to be the uniform behavior of one person.

According to the conventions of the machinery industry, it is the rule that outsiders are not allowed to enter the new factory. What's more, there is a contradiction between Lu Shipeng and Li Chunhe, and the other party will not come to Lu Shipeng's territory if there is no special purpose.

Now that the other party is uninvited, his eyes are still staring at the product, obviously he is coming to see the joke, Ji Donglai can now be sure that the other party got the machine tool.

"Haha, it's easy to say, guy! Call me if you have something, and when you're fine, we can communicate casually and find time to have two drinks together, haha......"

was broken by Ji Donglai, Li Chunhe was a thief, and left in a hurry, constantly cursing Ji Donglai for not understanding the rules.

There is always a chance that you can't eat and walk around, let's see.

"Thank you, Mr. Ji, we are quite willing to learn from you!"

Ji Donglai was about to go home, and before leaving, he explained to the students what he wanted to pay attention to the scene, and taught some unique skills to these people, and several student representatives sent Ji Donglai directly to the door.

Especially the students who often make mistakes in the past two days, stuffed Ji Donglai with a box of things.

"Don't be afraid to make mistakes, what our industry remembers is the process of constantly making mistakes and then correcting them, it's all dead things, just don't be smart!"

Ji Donglai did not refuse to accept the things given by a few people, after all, they were all the same age, and there were no valuable things.

"We are not afraid in front of you, but not in school, the master will scold us to death! On that day, we didn't clamp the workpiece, and the master scolded a student and cried! We later gave gifts to the old guy, and the old guy didn't scold us! ”

"Actually, we're all here to learn things, so why don't you get us to death? We can't figure out why we can order something so domineering these days......"

Several students from technical schools stood in front of Ji Donglai, spitting bitterness, Ji Donglai smacked his mouth, and secretly said that it would be like this in another twenty years.

Old mechanics, especially those who are old, have gone through a certain amount of factory experience.

Especially the old people who experienced the Angang Constitution, they all had eyebrows and eyes, so they were not surprised, and at the same time, their hearts moved slightly.

"If you students are worried about not being able to learn anything at school, then come here for an internship, and then I will give you an internship report! It is possible that the salary will be lower in the early stage, for food and housing, and enough for food, fish and meat! When you learn well, I will give you a salary increase when the time comes, and I will go back and talk to Mr. Lu! ”

Students who are interested in learning things are a scarce breed in any era, and they can choose some of the ones they need from them, and they just use this platform to do it.

Ji Donglai made up his mind and threw an olive branch to these children again.

"Okay Mr. Ji, when you come back and tell us, our classmates will come over, except for you, we are rarely willing to learn things from us, and we don't want to be scolded! Even if we give you money, we are willing to learn from you, and it is best to follow you after we graduate......"

Hearing that Ji Donglai allowed his classmates to also come for internships, the gang was very happy.

After all, there are very few places that are really willing to let Biotech come out for internship in recent years, even if it is that kind of state-owned enterprise.

Ji Donglai left a pager for one of the students, and agreed to paged the gang before coming back.

Originally, Ji Donglai wanted to go back to Hebei directly, but he didn't want to be called back by Wang Jue.

"What? My grandparents are here? Just kidding, the old man is not at home to recuperate, what are you walking back and forth? Just had surgery!

Hearing that his grandfather was coming, Ji Donglai had a big head for a while, and secretly played the piano.

"Cut, you don't come! It's not because of you, only you are studying in our family now, grandpa has to say that you can't miss your college entrance examination, go to the station to pick up people! Don't you have a car? Came to the counter to pick me up, just in time to bring something for the old man! ”

Wang Jue's eyes rolled for a while, and he didn't want people to toss back and forth.

But Ji Heng is that temper, and no one in the family listens to it.

Out of concern for his eldest grandson, Ji Heng had to come to support his grandson's college entrance examination, Ji Donglai had the impression that there was indeed such a thing, and the house incident happened a few years later.
