Chapter 355: Copycat Modification of Gear Hobbing Machine
"Don't you like to watch the fun? Come and see how the people who study with the great professor teach their apprentices. Learn from them carefully, or you will get so angry that you fail to teach your apprentice."

Director Wang took the opportunity to gather all the people who were watching the fun together to watch what Wang Luo would do.

With a "whoosh", everyone gathered around again. They had all seen Wang Luo processing the gears just now. His technique was really good. Since he was not shy and was willing to teach, and Director Wang also allowed it, they would be fools if they didn't seize the opportunity.

"You saw it when I was doing it just now. Come, I'll show you again. Watch carefully."

Wang Luo took a look at the drawings of the gears they were going to process, and all the data was imprinted in his mind. He immediately started to make the rough gear skillfully and started processing it. Just like before, it was so smooth that it was simply a work of art.

Before Feng Jin and the others could recover from their shock, Wang Luo had already removed the milled gear from the fixture and placed it in a finished product box nearby. He stepped aside and said to Feng Jin, "Okay, it's your turn."

"Can I do this myself?"

"Yeah, if you don't do it yourself, how can you learn it? Don't be afraid, I'll teach you how to do it."

Feng Jin was a little scared and tremblingly put the blank into the fixture. He had only been in the factory for more than half a year and was still familiar with the machine tools. How could he dare to process parts directly? The machine he used was the one that his master used because he had taken leave for something. Otherwise, as an apprentice, he would not have a separate machine to use. In his current situation, he could only help Jiang Guizhen and do some odd jobs like moving blanks. Wang Luo, on the other hand, just came up and let him start working.

"Be bold. You are very familiar with the machine. You have no problem with daily operation. What you lack now is practical operation and data calculation. A real man should be afraid of nothing. The more you are afraid of it, the less you will learn."

Feng Jin hardened his heart and became a little bolder.

"When clamping the workpiece, the force on each clamping claw should be even. After clamping, you can turn it around to see if the shaft is deviated... Yes, turn it like this. The algorithm of the dividing head is this: divide the scale number by the number of teeth on the gear, and use the remainder to select other scales..."

Wang Luo taught by example, guiding Yang Xin step by step in the operation. He is now proficient in top-level machining skills and knows how to operate the machine tools by heart. He knew at a glance that Feng Jin was about to make a mistake and immediately began to correct him. With his skills, teaching him a simple gear machining should be a piece of cake.

For the first gear, Wang Luo instructed him ten times and corrected five mistakes;

For the second gear, Wang Luo gave five instructions and corrected two mistakes;
In the third gear, Wang Luo only said one sentence;

The fourth gear, Wang Luo didn’t say a word from beginning to end.

Feng Jin trembled as she used a caliper to measure the gear for which she had complete intellectual property rights. After measuring the width of the last tooth, a bright smile appeared on her face: "It worked, it worked! Master Xiao Wang, you are really amazing."

"Haha, it looks like you milled this yourself. I didn't say anything."

Wang Luo became modest.

"You taught me well!" Feng Jin said, "I didn't understand what my master said. But once you started talking, I understood everything. It's still the same things, but you explain it better than her."

"Haha, Brother Feng, your master is right next to you. If you say anything more, she will really not want you as her disciple."

Wang Luo pointed at Jiang Guizhen, who had a gloomy face, and said with a smile.

"Master, you know I didn't mean that. Don't blame me. You will always be my master."

This silly fool.

A good teacher produces good students. Although Jiang Guizhen is a skilled worker, her skills are acquired through years of practice. Her understanding is far inferior to that of Wang Luo, so it is natural that Feng Jin will feel miserable if she teaches Feng Jin with such skills. Wang Luo has a thorough understanding of the principles of mechanical processing. He can tell at a glance what Feng Jin does not understand and can always give just the right hints. Therefore, Feng Jin has learned more in just one hour than he has learned in a week.

"Ah, it's better to be educated. In just an hour, you've trained a half-witted person to be able to process workpieces independently. I, Jiang Guizhen, am ashamed of myself."

Seeing that her apprentice who knew nothing was taught by Wang Luo in a short time, she felt a little disappointed. Although this apprentice was a fool, he was still her apprentice after all. Wang Luo was indeed much better than her. No matter what, she had to admit it.

"Yes, look at what this apprentice has done. We, a rough man, can't compare to him. Director Wang, you must keep Comrade Wang Luo in our factory for a few more days so that he can teach us more."

"Yes, Comrade Wang Luo must stay for a few more days."

Everyone expressed that at this time, if someone was willing to share technology and teach them things, that was definitely what they had dreamed of.

"Don't say that, everyone. Feng Jin is not stupid to begin with, and Master Jiang also laid a solid foundation for him, so I was able to teach him quickly. Don't push the blame on me."

Wang Luo waved his hand and said modestly.

"You are too modest. With your skills and the way you teach your apprentices, we dare not even think about it. Comrade Wang Luo, if you have time, I ask you to stay in our factory for a few more days and teach our workers. If you have any requests, please feel free to ask. As long as I can do it, I will do it for you. Even if I can't do it myself, I will try my best to do it for you."

"Director Wang, your words are a bit serious. Okay, I will stay here for a few days and give everyone a systematic training before leaving. Anyway, I don't have anything too urgent to do when I go back."

Since everyone said so, and the workers' eyes were thirsty for knowledge, he couldn't say no. He had no intention of keeping it to himself. You know, it would not have been easy if he had such a group of people willing to learn in his previous life. At that time, no one seemed to be keen on doing so. It was probably because there was too much knowledge and the society was too advanced.

Wang Luo called Director Ma and told him about the current situation of the machinery factory. Director Ma readily agreed to Wang Luo's request to stay in the machinery factory. He was very willing to see his subordinates apply the knowledge they learned to actual work, especially in a large factory like a machinery factory. If the workers can be trained, it will be good for all aspects. So Wang Luo stayed in the machinery factory and gave the workers a short-term training.

"Does your factory usually use milling machines to process gears? This efficiency is a bit too slow. Have you ever thought about modifying it yourself and making machines such as gear hobbing machines and gear shaping machines? Then the efficiency will be much higher."

After repairing the machine tool and explaining some training content to the workers, Wang Luo, led by Director Wang, visited the Qianjin Machinery Factory and discovered the reasons why the efficiency of the machinery factory has been very slow and the workers have high requirements.

He remembered that it was very simple to modify machines such as gear hobbing machines and gear shaping machines. In the past, there were many small mechanical processing workshops, which were factories with seven or eight workers and the boss. Their main business was to undertake the gear processing business of various large factories. In order to save costs, they bought some second-hand machine tools and modified them by themselves. The efficiency was very good, and one person could produce hundreds of gears a day.

My alma mater, Northwestern Polytechnical University, had a collaboration between the Department of Mechanical Engineering and the Department of Electronics on CNC gear hobbing machines, so the calculation is not that difficult.

"Ha, you think too highly of our factory's capabilities. Forget about anything else. No one can handle the maintenance of this milling machine. You're still counting on modification. You think our factory has eighth-level workers and engineers? That's relative to mechanical processing and the existing mechanical level. If you want everyone to modify it on their own, it's impossible to reach that level. It's very difficult. At present, our country has just stepped into the threshold of industrialization. We can't handle things that are too professional."

During the conversation, Feng Jin, a silly guy, happened to be standing by. After hearing Wang Luo talking about gear shaping machines and gear hobbing machines, which were terribly efficient, he asked, "Master Wang, what is a gear hobbing machine? Is it really more efficient than the current milling machines?"

"Gear hobbing machine..." Wang Luo scratched his head, "I can't explain it to you clearly, but it's a machine specially used for processing gears."

"I've never heard of it." Feng Jin said dejectedly.

In fact, it is not Feng Jin's fault for being ignorant. Gear hobbing machine is a special machine used to process gears. It has the advantages of high processing precision and high speed. It is generally suitable for mass production of gears. At that time, various mechanical equipment was in short supply in China. Gear hobbing machines were only available in a few large machinery companies. Medium-sized companies like Qianjin Machinery Factory could not use them at all. At Qianjin Machinery Factory, processing gears could only be achieved by using a universal milling machine combined with a dividing head, as Wang Luo taught Feng Jin to do.

Using a universal milling machine with a dividing head to process gears is not a big deal when the number is small, but it becomes very troublesome when processing hundreds of gears at a time. To process each gear, the dividing head must be repeatedly rotated dozens of times. Each time it is rotated, the tool must be re-calibrated before a tooth can be milled. Turn it again, calibrate the tool again, and mill another tooth, repeating the cycle. The workload is terrifying. Most people will feel dizzy just by rotating the dividing head.

"Well, Mr. Wang, since there is such a useful thing, can you modify it? If you can, why don't you make it? Then our factory will be very powerful. One person can process hundreds of gears every day, which is much better than the current milling machine that is so busy and inefficient."

Feng Jin didn't consider at all that Wang Luo was just staying to provide them with training and not to help them modify the machine, so it was a bit impolite to speak to him like that.

"You kid, it's good enough that Comrade Wang Luo can stay and help us with training and machine repairs. You are still thinking too much. There are so many things to do. Go and do your job."

Although he said so, Director Wang's expression was different. His eyes were full of hope, as if he wished that the network would agree immediately. However, he was too embarrassed to ask for it. People had already helped a lot, and if they wanted more, that would be a bit too much, and he felt embarrassed.

"Director Wang, you don't have to look at me like that. Just say whatever you want to say. This thing is not complicated and is easy to modify. You just need to make a few accessories separately. If you believe in me, I will figure it out for you and make a copy of the gear hobbing machine for you. For someone like Brother Feng who has some mechanical knowledge, it won't be a problem to process hundreds of pieces a day."

Wang Luo really couldn't stand the disgusting look from Director Wang. It would be fine if this look came from a beautiful woman, but it came from a middle-aged man in his forties or fifties. It was disgusting just thinking about it.

"Copycat? What is a copycat?"

Before Director Wang could speak, the silly Feng Jin showed up again. It seemed that he never stood on the same line with normal people. Everyone was talking about gear hobbing machines, but he changed the topic to what is a copycat.

"Get out of here and shut your mouth."

Director Wang really couldn't stand this idiot anymore. He felt like he would go crazy if he talked to Feng Jin any more.

"Director Wang, I'm just curious, please don't chase me away."

"Yes, yes, let Comrade Wang Luo tell me about it. I find it strange too."

The apprentice hadn't left yet when the master came again. Jiang Guizhen also put down her work and came over.

"Alas, it's true that the master has the same apprentice as him. I'm really pissed off by you two. Forget it. If I don't satisfy your curiosity, you two probably won't be able to work well today. Comrade Wang Luo, please tell us about it."

Originally, he was happy that Wang Luo agreed to modify the machine. He was so happy that he wanted to jump three feet high and hurriedly shake Wang Luo's hand. But unfortunately, the good atmosphere was ruined by the weird master and apprentice pair of Jiang Guizhen and Feng Jin.

"Shanzhai means... surrounding the city with the countryside, do you know? Shanzhai means millet plus rifles." Wang Luo said in a language that people at that time could understand.

"You mean the home remedy, don't you?"

"Is it okay for you to understand it this way?"

"You said you can process hundreds of gears in a day?"

"Uh, it should be okay."

"That's great. With this gear hobbing machine, our Qianjin Machinery Factory will soar to new heights. Our factory mainly processes gears. Comrade Wang Luo, thank you very much. If you have any requests, please feel free to ask. My office is yours now. Take it and use it as you like. Yu Zhitong, Yu Zhitong, come here for a moment."

Director Wang was delighted at the thought and no longer cared about the master and apprentice Jiang Guizhen. He immediately began to happily provide Wang Luo with the necessary conditions and called the mechanic over.
