Countercurrent 1982

Chapter 11 Master
"Brother, what if you give someone a free repair if you lose money?" Duan Fang said worriedly, she would not have thought about how low the repair cost of her brother was.

"Don't be stupid, your brother, am I a person who does that kind of business at a loss?" Duan Yun smiled at his sister and said, "It's not good for other teachers to help you promote it for nothing? You may not even have ten mouths. Words work."

"When did you become so smart?" Duan Fang felt that her brother seemed a little different now...

"Your brother, I was originally a wise man, you just didn't realize it."

"Bragging!" Duan Fang stuck out her tongue when she heard the words, put the money in her pocket and continued to cook happily.

Duan Yun glanced at the 30 yuan he just got, and was quite happy in his heart.

But he also knew that modifying radios was just a small business, and if he wanted to make a lot of money, he still needed to think of something else.

In fact, Duan Yun also thought about a lot of things in the past two days after his rebirth.

He obviously wouldn't be willing to be an ordinary worker in a factory all his life, but judging from the current situation, doing business is a bit risky, speculation is a serious crime these days, and even if he is willing to take risks, he doesn't have enough capital on hand.

As for taking the college entrance examination and going to university, at least he will have to wait until next year to have the opportunity, and Duan Yun has spent most of his life studying on campus. Since he has relived his life once, he will always have to change his way of living.

The safer and more practical way now is to mix in the factory first, repair an electrical appliance part-time after get off work, and then consider the next step when you have more money on hand.

Duan Yun even thought about opening an electronic or mechanical company by himself. With his technology, he can make products that are ahead of the times, but it is impossible to open a factory in a city right now. It may be possible to rely on a rural cooperative. , but Duan Yun still needs to prepare a lot of money.

In short, the road has to go a little bit, and the meal has to be eaten in one bite.

After the sister made lunch, the brother and sister sat down and ate together.

If it wasn't for the extreme hunger, Duan Yun really didn't want to eat such a meal. His appetite had already been raised by the brilliant cooking skills of his fiancee Luo Yanjun in his previous life, and ordinary food was hard to see.

But thinking of his fiancee at this moment makes Duan Yun a little sad. He still clearly remembers the scene where the two were hit by a speeding car at the same time, but he just doesn't know how she is now...

After the meal, after brushing the dishes with his sister, Duan Yun lay directly on his bed.

He has to work night shift at night, even if he is not sleepy now, he has to sleep for a while.

The night shift is the most exhausting. From twelve o'clock in the evening to eight in the morning, it is already nine o'clock after changing clothes and returning home. If you can't eat well, you can't sleep well, and no one can eat it for a long time.

But Duan Yun also understands that the secretary and the leaders of the first workshop do not want to see him, they want to let him retreat, but since Duan Yun intends to engage in technical work, he will definitely not bow his head...

……

At 11:30 in the evening, Duan Yun took the lunch box his mother prepared for him, gently opened the door and went out.

At night, the sky is quiet, the sky is full of stars, and the air is a little cool.

On the street leading to the gate of the factory, the lights on the two roads were dim, and sporadically, some commuting workers could be seen passing by on both sides of their bicycles.

When Duan Yun came to the door of the first workshop, Huang Haitao, the third squad leader in charge of the night shift this week, had been waiting for a long time.

Huang Haitao is in his early forties and is a veteran lathe worker with more than 20 years of experience. He is flexible and quick-witted, and he is also close to the chief engineer.

"It's alright, I'll be late a few minutes late." Huang Haitao glanced at the Shanghai plum blossom watch on his wrist, patted his shoulder and said, "Go and change into work clothes, and I'll arrange for a master to take you."

"Okay." After Duan Yun finished speaking, he walked quickly to the locker room.

And when Duan Yun put on his clothes and walked out, there was an old man with white temples beside Huang Haitao at the door.

The old man was cleanly dressed and looked about 70 or [-] years old, but his eyes looked very energetic.

"Duan Yun, this master's name is Han Zhong. He will be your master from now on. Master Han is an old technician in our factory. He was rehired from retirement. He is of a high level. You can study hard with Master Han in the future!" Huang Haitao said to Duan Yun calmly.

"Hello, Master Han." Duan Yun greeted Han Zhong with a smile.

"Yeah." Han Zhong didn't seem to be interested in the new apprentice in front of him, he just replied with a blank expression.

The master of the factory these days is not the honorific title that was called out in later generations, but a real master-apprentice relationship.

As the saying goes, one day is a teacher, and a lifetime is a father. The old master not only teaches the skills to the apprentices, but also acts as a backer for many new apprentices.

When apprentices learn from their masters, they must concentrate fully on their work, and they must not be lazy or distracted in their work, otherwise they will be reprimanded. , and even help with retirement.

While some mentor-apprentice relationships are not that harmonious, this has generally been the case these days.

"That's it, Master Han, you can lead Xiao Duan to get familiar with the next station first, and arrange tasks for him by the way." Huang Haitao said, turned around and walked to the other stations.

Duan Yun immediately followed behind Han Zhong and walked to the workstation on the side of the factory.

At this time, when the workers at the station saw Duan Yun, their eyes were a bit weird.

Now Duan Yun is already a celebrity in the factory. Before, it was well known that he committed suicide for a female worker. Many young workers even called him the number one 'love saint' of the Red Star Gear Factory behind his back.

Duan Yun naturally saw everyone's curiosity and ridicule towards him, but he didn't care about it. After all, he was a mature middle-aged man in his previous life, and his face thickness and experience were beyond the reach of the previous owner of this body.

At this time, Duan Yun's thoughts were temporarily focused on his new master. He was a little curious about Han Zhong. You must know that state-owned enterprises in the 80s rarely rehired. Usually, the master retired and the apprentice took the top. There is no shortage of labor, and what kind of high-end technology does the old man in front of him have, so that the factory will rehire him.

But when Duan Yun followed Han Zhong to his workstation, he suddenly realized.

It turned out that the lathe used by Han Zhong was the former SL lathe produced in 1952 that he saw during the day!

Even in the 80s, this old-fashioned lathe was almost eliminated in China, and it looked like an old antique.

In fact, Hongxing Gear Factory wanted to scrap this machine tool two years ago. However, due to the increasing number of orders from factories and mines and the huge production task of Hongxing Gear Factory, all workshop leaders finally decided to continue to use this master machine tool. One of the few old employees who can play with this lathe, Han Zhong was eventually retired and rehired, and together with this machine tool, he continued to use his waste heat for the factory...

"You can just watch by the side, and help me get the materials by the way." After Han Zhong settled down with Duan Yun, he started the machine and started the night shift work tonight.

Han Zhong's workshop is specialized in processing the column head of the single hydraulic strut. Because this old lathe has low precision, slow speed and large vibration, it can only do the rough turning step of the column head, and the fine turning is replaced by another domestic machine. Lathe processing.

Han Zhong obviously didn't want to seriously teach Duan Yun. For more than an hour, he basically didn't look at him directly, except for instructing Duan Yun to take the material and put it on the chuck.

As the so-called church apprentice starves the master, it is probably because of this reason that Han Zhong is a little cold to Duan Yun, the new apprentice.

In fact, there is no need for Han Zhong to teach him, Duan Yun is also good at turning technology. When he graduated from college, he was a technician in the machining workshop. Although the factory has already used a lot of imported five-axis lathes, there are still a few ordinary cars. Still machining parts with general accuracy.

Duan Yun once asked the workers how to use the lathe in his spare time. During the three years in that factory, he was considered a half-skilled worker, and he was able to process some slightly difficult parts.

So even though the machine used by Master Han Zhong is very old, after just watching it for a while, he feels that he can already use it.

While the master didn't speak, Duan Yun didn't say anything, just stood beside him.

The night shift work was a bit long and boring, but Duan Yun kept thinking about some technical issues at work in his mind.

In Duan Yun's view, if only a simple workpiece such as a hydraulic prop column head has been processed, then some simple technical improvements can be made to make this work simple and efficient.

After thinking about it for a while, Duan Yun found half of the stone pen and squatted on the ground to draw a design idea.

Although ordinary lathes have differences in machining accuracy, their working principles and operation methods are basically the same.

Like the stigma of this hydraulic strut, it is divided into two steps: rough turning and fine turning.

The so-called rough turning is to process the cut metal materials to a certain reserved amount, while the finishing is to further improve the machining accuracy on the basis of rough machining.

In the case that the workpiece accuracy requirements are not too high, Duan Yun can directly convert this lathe into a high-efficiency automatic lathe.

In fact, as early as the 60s in China, factory technicians had already modified automatic machine tools, but that was only a very small-scale use.

The main reason why this kind of modified machine tool has not been promoted on a large scale in the country is that the modified lathe can only process a single workpiece due to its simple technology. Improvement, and due to some limitations and defects in early domestic technology and design, it is prone to problems, so this technology has limitations.

But this modification is very suitable for Duan Yun's current work situation.

Due to the slow rotation speed, large vibration and low precision of this old machine tool of the master Han Zhong, it can only be used for a single product such as a thick lathe column head, which is very suitable for automatic modification.

In addition, Duan Yun's electro-mechanical skills are not comparable to those of the old lathes and technicians in the factory. It is a trivial matter to modify such a lathe.

Duan Yun squatted on the ground and continued to write and draw with a stone pen, repeatedly revising several plans, while his master Han Zhong simply regarded the newly recruited apprentice as air and was just concentrating on his work.
