Rebirth of Military Workers

Chapter 202

“Lao Wei, why are you leading the team? I told Lao Wang, so don’t bother you with such trivial matters?” Zheng Yucheng hurriedly stepped forward to help the old man walking tremblingly in front of him. .

The old man has white hair, wrinkles on his face like old mulberry bark, and his eyes are muddy, as if he is about to die.

“It wasn’t that Xiao Wang arranged for me to come over. I always stay in the factory, my old bones are rusty. It’s okay to come out and walk.” Wei Lao looked at Zheng Yucheng, the wrinkles on his face squeezed closer. Up.

“It’s not bad to go out for a walk. We are too disgusted during this time. Apart from tossing a few apprentices, there is nothing to do.” Another white-haired old man said. “What’s the situation here? What shall we do?”

“Lao Liang, I have been working hard on this journey. Let’s eat and rest first, and we’ll talk about it tomorrow morning.” Zheng Yucheng said with a pious face.

Chen Degui saw Zheng Yucheng in such a state for the first time.

There is no air of leadership, and there is no such momentum that Lao Tzu is the number one in the world.

Even in Sun Daogan, he would not give a good face.

Who is Sun Daogan? That was the secretary of a large unit like Qin Fei with more than 100,000 people!

“Fucking, we have so much time to waste? First figure out how to do it. Put a cushion in the workshop and make a few quilts.” Hearing Zheng Yucheng’s words, Wei Lao, who took the lead, was immediately unhappy.

The whole person’s momentum has changed.

“Wei Lao, Liang Lao, we haven’t finished the inspection yet, let’s take a rest!” Xie Kai knows that these old men are used to working all the time, but looking at the old man’s body, he will continue to work and work. They can’t afford it.

“Xie family boy? You are good, you can toss, and you have tossed us all here.” Wei Lao looked at Xie Kai, his muddy eyes brightened instantly.

Hearing Wei Lao talking about the Xie family boy, the eyes of a group of old men who just got out of the car fell on Xie Kai.

Xie Kai suddenly became uncomfortable.

“Old Wei, don’t make fun of him. This kid is timid!” Zheng Yucheng smiled and helped Xie Kai escape. “This is Chen Tongan, director of Fengcheng Optoelectronics Research Institute; this is…”

A greeting, but the old men from 404 didn’t pay much attention to Chen Tongan’s director. They just shook hands and urged to talk about things.

Chen Degui, who kept humming and asking for warmth, didn’t even take a second look at it anymore.

Seeing these old men, Xie Kai suddenly felt that in his previous life, he should have been influenced by his master, so he was uncomfortable with the world.

If these old men belong to Chen Degui or Chen Tongan, then…

Xie Kai knows that this kind of awesome people are arrogant in their bones. They spend all of their time studying technology. They don’t have time to think about people’s worldliness, and they don’t care about the mess of promotion and salary increase.

After these old men can’t do anything, there will be fewer and fewer nine-level fitters at the 404 base.

When the mind becomes more complicated, the energy devoted to technical research is naturally less.

As Master Xie Kai said, it is impossible for Xie Kai to reach the level of nine-level fitter in his entire life, even if he has more theoretical knowledge than the teacher, and he understands programming and PLC circuits that Master does not understand.

“…This is the situation. The broken parts need to be re-produced, there are no drawings, no high-precision measuring instruments…” In the workshop where the equipment was stacked, Cheng Tongan introduced all the faults they had checked.

At this time, Old Man Wei was totally different from the previous one, and his whole body became radiant.

“These are the most manufactured precision equipment in the world. As long as a little accuracy is not reached, it will affect the accuracy of the entire equipment.” Chen Tongan emphasized.

“Everyone talk about your own ideas, and you understand the situation.” A group of old men gathered around a German-made lithography machine on the spot. After they learned where the equipment was malfunctioning and which parts needed to be replaced, they began to discuss without anyone else. .

Old man Wei who led the team asked everyone.

After discussing a plan, they will begin to disassemble various components and even parts.

“First, make some replacement parts, replace them gradually, and take the physical and chemical analysis of the replaced ones to figure out what materials are used and what are their characteristics.”

“I agree with Lao Liang. But we must replace them one by one to ensure the accuracy of the assembly.”(Read more @ wuxiax.com)

“Start with non-critical components, and replace one if you find one. Only in this way can we ensure that the parts we produce can fully match the original ones and achieve the original accuracy requirements as much as possible.”

A bunch of old men, you say and I say a word, the people next to you can’t figure out what they are discussing.

Imitation, shouldn’t it be disassembled first to survey and map the parts?

They didn’t even ask Chen Degui for measuring tools.

“Director Zheng, you can ask someone to help us remove the tools from the car.” Soon, Old Man Wei and others came up with a plan and said to Zheng Yucheng.

It seems that Zheng Yucheng is not their leader.

After listening, Chen Degui hurriedly arranged for someone to move the tools in the car.

There are more than a dozen small boxes made of wood, and I don’t know what’s in them. They are not too heavy.

The toolbox came over, and the old men in twos and threes studying how to start each found their own toolbox. When the inside was opened, everyone was dumbfounded.

There are no high-precision tools inside. If you have to say there are, the micrometer is the top precision measuring instrument.

In the toolbox, most of them are various types of files, sandpaper, and even cotton, silk, etc.!

The artifact used by the nine-level fitter!

The main thing is the file.

The world spreads, a file is in hand, fitter goes all over the world.

“Director Zheng, they use these equipment…” Chen Tongan was a little worried, “Once you can’t install it again, it will be a problem.

“Don’t worry, they know that everyone’s tools are measured by themselves after they have used them for many years.” Zheng Yucheng said calmly, “Aerospace rockets and missiles, many high-precision parts, they rely on these measuring tools. Processed.”

Xie Kai knows that these old men’s measuring tools are not ordinary goods on the market. Although they are mechanical, their measurement accuracy is not high. With the experience of these old men, the accuracy is higher than the most precise electronic measuring equipment in the world.

Some equipment is a group of two or three old men, and some equipment is handled by one person.

They carefully disassembled the parts in various positions, then installed them, and then disassembled and installed them again, ensuring that they can be installed back to their original positions after disassembly.

Time has passed so slowly. Cheng Tongan’s people have been hacking for a long time, but they can’t take a rest. The old men need their cooperation and ask them about the role of each part and the relationship with other parts. How much accuracy will be worse? What is the impact.

“Isn’t it about to be demolished? It’s almost dawn.” Chen Degui was a little anxious.

He wanted to ask if the old men could do it.

“If you are not satisfied, you can go to sleep.” Zheng Yucheng said to him.

Chen Degui really wanted to, but he didn’t dare to leave. Their repair shop was ordered to be on standby after the old man arrived. They must provide the rough machining they need in the first time according to the old man’s requirements.

Until dawn, everyone was exhausted and greasy, and the old men were still full of energy.

“It’s disassembled!” Xie Kai has been observing the actions of the old men. They repeatedly disassemble, install, and then repeat again, just to test the assembly accuracy of the various parts of the equipment, and to ensure that the parts they processed can be consistent with the original processing accuracy. .

As for materials and heat treatment processes, they have no alternative.

Only after the material is replaced, use physical and chemical analysis to determine the material and performance of the part, and then consider using the material with the closest performance to produce the part for processing.

The nine-level fitter at the 404 base can not only file high-precision parts with a file in their hands, but they also understand the characteristics of the material!

Pao Ding Jie Niu must know how the meridians of all positions on the cow body are.

Finally, someone did not reinstall the removed parts, and began to draw sketches with the work notebook that he carried with him.

As a signal, other people also start to draw pictures.

“Xiao Chen, let the people in your repair shop process them according to the requirements on these drawings.” Liang Lao handed the drawings drawn on the work notes directly to Chen Degui, who was about to be unable to hold on.

“Well, is the accuracy above too high?” When the director of the 691 factory repair shop saw the drawing, he couldn’t help being dumbfounded.

Their workshops are all ordinary skilled workers.

The dimensional tolerances on the sketches are almost always within 0.02 mm, and many are even within 0.005.

“Lao Wei, the technical conditions here are not as high as ours, and the precision is too high and they can’t process it…” Zheng Yucheng said to Wei Lao embarrassed after learning about the situation.

“If this accuracy is not achieved, our time will not be guaranteed.” Wei Lao frowned.

“No time is required.”

“That way, all tolerances can be enlarged to within 0.05. They can only be large, not small, otherwise they will be useless.” Wei Lao replied after discussing with others. “We can only leave a little more margin. Let them pay attention to the location of some holes. If there is no guarantee, we will leave the margin.”

“Okay, I will guard it myself!” Zheng Yucheng said.

He knows the importance of pre-processing to ensure accuracy by hand.

There are a lot of seven-level workers and eight-level workers in the 404 base, and the old men put forward their requirements completely in accordance with the standards of the base.

The repair workshop of the 691 factory does not have much finishing ability, and naturally it cannot meet the requirements of the old men.

“That’s OK, let’s make arrangements. We must process these in the morning. Let’s eat something, sleep for a while, and do our work in the afternoon. We should be able to get all the parts out tomorrow morning.” Old Wei nodded and said nothing.

In the morning, they ate something in the cafeteria of the 691 factory. They went to the factory guest house to sleep.

Chen Tongan watched all night, but never figured out what these old men were doing.

You can’t see what’s wrong with it at all!

The legendary nine-level fitter is also very ordinary.
