Chapter 294 Machine Tool Apprentice
Whether Shi Jian's prayer can become a reality is another story. Now that the mountain is covered by heavy snow, he is unable to investigate carefully.After confirming the location of the salt mine, Shi Jian went into intense production again, and Mei Zi, Zhang Jian and Yi Hengge also officially started their machine tool apprenticeships.

In fact, even Shi Jian's operation of various machine tools is limited to meetings, and he is not proficient at all. After all, the major of mechanical design is not mainly about operating machine tools, but more about design.But even so, Shi Jian taught these three rookies who knew nothing at all, it was more than enough.

The three of Meizi were also very eager to learn, and even Yi Hengge, who was always slick, put away his smirk and listened meticulously to Shi Jian explaining the operation methods and precautions of the machine tool to them, not daring to be sloppy.

If you are not serious, it is absolutely impossible. For those who have only elementary school education and basically no knowledge of geometry, the selection of knives and angle adjustment are like heavenly scriptures, and they cannot be understood thoroughly.

In the end, Shi Jian had no choice but to teach the three people geometry knowledge from scratch, and it took a few days for them to understand what was going on.

"It's terrible to be uneducated." Shi Jian privately sighed to Feng Kuang.

Instead of comforting Shi Jian, Feng Kuang hit him instead, and said gloatingly: "Yes! Who told you to drag the three of them away? Just take Zhang Weiqiang there. That kid is playing with woodworking lathes and Like."

Shi Jian said with a bitter face: "You think I don't want to bring him here, but now the foundry needs him to make sand molds, how can we do without him?"

"Then don't complain. You want the horse to run well, but you also want the horse not to eat grass. You have it all." Feng Kuang said unceremoniously.

Shi Jian murmured, "Why don't they let them eat grass? I just want to train a few more people."

Feng Kuang pointed at Shi Jian with his finger and said, "I think you want to squeeze the surplus value of all of us, and look like a capitalist. Are your ancestors landlords?"

Shi Jian curled his lips and said, "I won't talk to you anymore, I'll continue to teach them." Then he walked outside.

Feng Kuang pointed at Shi Jian's back, and said with a smile: "Boy, don't run away, your ancestors must be big landlords, or the kind of big landlords who specialize in exploiting long-term workers, like Huang Shiren!"

Shi Jian staggered and almost fell, thinking to himself: "Old man, I really made you guess, but am I so black-hearted?"

"President Shi's heart is too dark," Yi Hengge complained softly to Zhang Jian in the reading room of the former fire brigade, "Look at all these things, they are stuffed and pressed for a while, and they have to be pulled out again for a while. Press it again, how can I remember it? The most difficult thing is that I can’t remember that he didn’t let me go back to my room to sleep, and I just memorized it all night, and Vika is still waiting for me.”

Zhang Jian sighed, and said, "Forget it, if you have the time to complain, you can recite it more, maybe you can go home and sleep with Vikado in your arms, otherwise, she will really be alone tonight." bed."

Meizi raised her head from the side and said, "Then you two continue, I'm going back to sleep."

"Didn't Mr. Shi say he couldn't memorize it and wouldn't let him go back?" Yi Hengge said.

Zhang Jian patted him and said, "You idiot! Of course Meizi memorized it all, why don't you just go back to sleep, right Meizi?"

Before Meizi could thank him, Shi Jian walked in and asked after hearing Zhang Jian's words, "Did Meizi memorize it?"

Meizi nodded and said, "I've memorized it, Mr. Shi." After speaking, he memorized the knowledge of trigonometric functions.

Seeing that Meizi memorized it quickly, Shi Jian nodded approvingly, and said, "That's right, let's go back and rest, but we can't relax in the future, the operation of the machine tool is very important."

When Meizi walked out the door with a smile, Shi Jian turned to Yi Hengge and Zhang Jian and asked, "How are you two? I can do what I say. If anyone can't memorize it today, don't go back to sleep until it's memorized." until."

Yi Hengge was about to say that neither of them knew it yet, but Zhang Jian stood up and said, "Let me recite it." Yi Hengge's eyes widened all of a sudden, and he was alone for a long time I can't recite anything.

After Zhang Jian also went out, Shi Jian came over and asked, "Hengge, how much can you recite?"

Yi Hengge hesitated for a long time before he said dully: "Mr. Shi, I mainly just can't figure out what it is. It's too convoluted."

Shi Jian patted his forehead when he heard the words, and said: "Oh, blame me, blame me, I used to say it before, you can't remember this, just memorize sine, cosine, tangent and cotangent."

This time Yi Hengge finally figured it out, and quickly recited it, and was finally able to go back to the house and sleep with his wife.

For several days, Shi Jian was teaching these basic knowledge, and only after finishing what should be said, he began to formally teach them how to operate.

"I have already told everyone what should be said. Now each of you will take turns operating the lathe. Today's practice is to produce a hammer from the machine." Shi Jian said while handing them a three-dimensional view of the hammer. It is clearly marked.

The hammer can be said to be the first finished product for most people who learn how to work as a lathe. Shi Jian did the same at the beginning. Shi Jian took the hammer home and kept it there.

Because the lathe to be repaired is actually a machine tool integrating turning, boring and drilling, Shi Jian also made it a little more difficult, asking them to make the hammer head and hammer handle separately, and then combine them together through threads.

This request tortured the three of Meizi to death. Although the shape of the hammer could be turned out, they were completely stumped when drilling and threading.

"Mr. Shi, I have failed three times. It seems that I really don't have my day." Meizi said dejectedly.

Shi Jian patted him on the shoulder and comforted him: "It doesn't matter, we don't lack materials now, don't panic, take your time."

Meizi gritted her teeth, nodded vigorously, picked up a piece of steel again, and started working again.

Yi Hengge looked at Meizi's repeated failures, and felt a little nervous. He said to Zhang Jian, "Brother Jian, you said that Meizi has failed so many times, can we do it?"

Although Zhang Jian didn't have much confidence in his heart, he still said: "It's okay, didn't you hear what Mr. Shi said? There are plenty of materials. If it doesn't work once, it can be done twice. I don't believe that we can do it a hundred or eighty times. Can't do it."

Yi Hengge nodded and said, "Yes, practice makes perfect, anything can be done."

Shi Jian was listening to their conversation, his heart hurt like blood, and he said to himself: "You guys have to do a hundred or eighty experiments with a hammer, so what else can you do in the future?"

But he couldn't say this, otherwise, they would be even more nervous.

Meizi finally succeeded in making the hammer for the fifth time. He screwed the hammer head and the handle together, looked at the tight seam of the hammer, felt a sense of pride in his heart, and said happily: "Mr. Shi, It finally worked! Can I do something else?"

Shi Jian took the hammer over with a smile, held it in his hand and looked at it carefully, finally nodded with satisfaction, and said, "Yes, you did a good job this time. But let's practice a little bit first, and wait until you can operate it proficiently." After that, you can make other things.”

Meizi immediately said, "Then Mr. Shi, what should I do next?"

"Next? You should rest first," Shi Jian pointed at Zhang Jian and Yi Hengge with a smile, and said, "Are you a little anxious if you haven't seen them?"

Meizi smiled embarrassedly, walked to the side and sat down to rest, while Zhang Jian got a little luck, walked forward, put aside the drawings he had already read, and started his first machine tool operation .

What Shi Jian didn't expect was that it took Zhang Jian five times to make the finished product, but Yi Hengge succeeded in two.

"Mr. Shi, come and see, is the one I made the best?" Yi Hengge shouted excitedly, waving the hammer in his hand.

Shi Jian took the three hammers together, compared them, then measured the size with a tool, and said: "Not to mention, Heng Ge's is indeed the most standard one, and it takes the shortest time. It seems You are very talented in this area, practice hard in the future, you know?"

Hearing that he was the best, Yi Hengge's self-confidence suddenly swelled up, and he said: "Mr. Shi, why don't you make one too, and let us see your craftsmanship."

Shi Jian knew that this kid wanted to show off again, so he agreed, picked two pieces of steel and walked over, and quickly produced the hammer head and handle, assembled them together, and handed them to Yi Heng Ge said, "Take a caliper and measure it yourself. Didn't I teach you how to use it?"

Yi Hengge took it over and took a caliper to measure it, and immediately said in admiration: "Boss Shi is still amazing, the project was completed so quickly, and the size is not bad at all, I am convinced."

Shi Jian scolded with a smile: "There's so much nonsense, how can I teach you guys if I haven't done this twice?"

Yi Hengge laughed and said, "Boss Shi, what should we do next? Make arrangements."

Shi Jian shook his head and said: "You already know how to operate it, the next thing you need to do is to think about what can be processed from our daily necessities, and then do it yourself. If you think about it, you can Tell me, I will draw the drawings for you, of course you can also draw them yourself."

After Shi Jian finished speaking, he went back, leaving the three of them thinking about what to do.In the end, everyone made an item that they wanted to make, and the most peculiar thing among them was the one made by Yi Hengge.

This thing was built by Yi Hengge alone, and Shi Jian was not asked to draw a design drawing. Moreover, during the process of processing, he took it off from time to time and put it in his hand to compare it with, until finally he held up a reserved one. Looking at the mushroom-headed cylinder, he proudly said: "The ratio is absolutely one-to-one. When I am old, I can show it to others and tell those young people that I used to be very majestic, grandpa." !"
