Chapter 1482 Shorten Thirty Years

"Would you like to go get something to eat first?"

Seeing Yang Xiaotao finishing the fourth part, while taking a rest and drinking water, Yang Youning immediately stepped forward and expressed concern.

"The canteen makes boiled bones and pies. You should eat some to replenish them first!"

Yang Xiaotao looked at Liu Daming and others who were eating next to him, felt his physical condition, and then shook his head, "No, I feel pretty good now, let's work hard."

Yang Xiaotao refused, but Yang Youning didn't say much, picked up the pancake and stood aside to watch.

People around him left and came back, still filling the warehouse.

Next to them, Liu Daming and others in the rest area drank the bone soup, solved their personal problems, and walked towards the machine.

Eat and drink enough and start working again.

At three o'clock in the afternoon, Yang Xiaotao gently put down the finished parts. The discomfort coming from his body told him that he needed to rest.

High-intensity work, high mental concentration, and exhaustion of physical energy are not a small amount.

Coming to the side, Chen Gong immediately handed the jar over to Yang Xiaotao to sit down and rest.

At some unknown time, Mr. Xia and Mr. Sun from the First Machinery Department came to the scene, accompanied by Liu Huaimin and Yang Youning.

Several people saw Yang Xiaotao resting and did not come forward to disturb him.

People around him looked at Yang Xiaotao with admiration.

From morning to now, Yang Xiaotao has made a total of six parts.

It doesn't seem like much, but compared to the others, only Liu Daming and Liu Gong have done something qualified so far.

The accuracy testing of parts made by others is not perfect.

The one Liu Gong made also cost three materials.

It's not like Yang Xiaotao, who goes through it all over again.

The efficiency and success rate are simply incredible!
So much so that in the end no one dared to waste materials.

"Old Liu, take a rest!"

Ten minutes later, Yang Xiaotao drank two bowls of broth, chewed a large piece of bone and meat, then got up and walked into the venue.

Liu Daming had a wry smile on his face, "I'm old and no longer useful!"

People around him bowed their heads and were shocked.

"Don't worry, I'm here!"

The young man's voice came from the front, and the people around him raised their heads again after hearing it.

As night falls, the machinery factory becomes more and more lively.

Many people who got off work did not leave the factory. Instead, they stayed in the workshop and outside the warehouse, as if waiting for something.

At the gate, Liang Zuoxin had just been notified that his superiors were coming, and he quickly sent people to guard the gate.

Not long after, two cars appeared on the road and quickly arrived in front of the door.

"Chief!"

When Liang Zuoxin saw the people sitting in the car, he immediately came forward to see them. The people nodded, and then the car entered the machinery factory.

Cars followed closely behind.

"Watch the door!"

Liang Zuoxin gave instructions and immediately got on his motorcycle and followed the convoy.

The car stopped, and Liang Zuoxin immediately guided several people out of the car and walked to the warehouse.

At the gate, Mr. Xia and Liu Huaimin and others had been waiting for a long time. When they saw Mr. Huang and Mr. Chen following behind, they immediately stepped forward.

"Chief!"

"lead!"

Several people had seen it. Mr. Chen tightened his cotton-padded clothes and walked inside while asking, "What step are you at now?"

"There are thirteen core components, twelve of them have been completed."

"One of the hardest controls bearings are doing!"

"Now for the second try!"

Mr. Xia explained that he spent most of the day watching here, but he didn't feel tired.

My mind is entangled in successes and failures over and over again, and even time feels faster.

Of course, compared to Yang Xiaotao, they were all more relaxed!
Chen Lao didn't say much when he heard what was said, and quickly walked through the crowd and came to the innermost part.

What caught his eye was Yang Xiaotao sitting on the ground playing with workpieces.

The people around him wanted to remind him, but Mr. Chen raised his hand to stop him.

"Chief, what you just did was not up to standard."

"Xiao Tao is checking the problem."

Mr. Chen nodded, and then looked to the side, where parts were being installed amidst everyone's busy work, and the outline of a machine tool that he had never seen before was rapidly taking shape.

"Chief, this time, thanks to Xiaotao."

Mr. Xia whispered from the side, "There are thirteen core components, and he completed eleven of them by himself!"

Mr. Sun also nodded, "This kind of precision requirement has exceeded the capabilities of ordinary eighth-level workers."

"I guess there is no other person in the country!"

Mr. Huang took a deep breath and said, "Our country is lucky to have one of these people. How many more do you want?"

"That's true!"

Mr. Chen didn't say much after hearing this, but he was just thinking about the impact on the domestic manufacturing industry if such a high-precision machine tool was produced.

How many years will it drive the machinery industry forward?

Since foreign countries imposed a technical blockade on China, the domestic machine tool industry has lagged behind for at least fifty years.

Fifty years, what a gap between two generations.

Moreover, there are too many constraints on domestic development. If we cannot catch up, the gap will only get wider and wider.

That's why they assigned tasks to various machine tool manufacturers to research better machine tools to shorten the gap.

But what a result.

Many machine tool factories have tried it, and the best ones are only on the same level as Venus.

It can be seen how difficult the technical barriers are.

Right now, Red Star Machinery Factory is their last hope.

The young man in front of them is their last hope.

"It should be ten years!"

Mr. Chen tried his best to think better and boldly, and then his heart was filled with expectations.

Huang Lao and the others had glaring eyes, trying hard to suppress their inner excitement, but they had to suppress it and keep quiet.

People around him didn't even dare to talk about it. Even if they had various thoughts in their hearts, they could only hold them back.

A group of people stared at Yang Xiaotao.

At this moment, Yang Xiaotao was holding the parts and comparing them with the drawings.

According to your own design, there should be no problems with the parts produced!

Two symmetrical bearings, no problem.

Materials used, no issues. Where did it appear?
The accuracy of the production should meet the requirements!
How could it go wrong?
It’s wrong twice in a row, it shouldn’t be!

Be puzzled.

Yang Xiaotao touched his head and suddenly felt a little cold.

The night was getting cold, and he only wore an autumn coat and a shirt. It was still too hot for physical activity when he was working, but now he felt a little cold sitting down.

cold?
Suddenly, Yang Xiaotao immediately took off his gloves and touched the surface of the component with his hands. It was cold.

This is a piece of copper tungsten alloy.

Yang Xiaotao didn't know what the expansion coefficient of this alloy was, but he understood one thing.

Thermal expansion and contraction.

"Hahaha, no wonder, no wonder!"

Suddenly, Yang Xiaotao chuckled.

Everyone around was curious, and Mr. Chen and the others even stepped forward.

Looking up and seeing everyone, Yang Xiaotao stood up and patted the parts, then smiled and said, "I understand, I understand!"

"Understand what?"

Yang Youning asked anxiously.

Yang Xiaotao nodded to Mr. Chen and others. Seeing everyone's curiosity, he immediately looked aside, "What's the temperature now?"

"how many degree?"

"The temperature!"

People on the sidelines immediately started asking questions, and some even ran out to check the thermometer.

"What does the temperature have to do with it?"

Huang Lao asked from the side.

"Chief, this metal has a special characteristic: it expands with heat and contracts with cold!"

Yang Xiaotao said with a smile, while Chang Mingjie and others on the side bowed their heads and stamped their feet, mumbling.

Huang Lao and others also reacted, and then a shout came from outside, "Fahrenheit 42!"

Then I saw a person holding a thermometer to me.

Yang Xiaotao took a look and realized that it was less than six degrees!

Then he explained to everyone, "Under normal circumstances, compared to about 20 degrees at normal temperature, this temperature difference will have little effect on the metal, but when the accuracy is extremely high, a little change will affect the final result. "

After hearing this, Yang Youning didn't think much. Since he found the problem, he solved it.

"Quick, light the brazier!"

"Take a few more, and the extra people can go out and close the doors and windows."

"Old Li, find someone to block the window."

"Turn on the lights!"

Everyone cheered and got busy.

At this time, Yang Xiaotao came to the rest area and started to replenish his strength.

Mr. Chen sat aside with a kind expression.

"Xiao Tao, tell me something right. With this machine tool, how much can we shorten the gap between us and foreign countries?"

After Mr. Chen finished speaking, Mr. Huang and others were also listening.

The people in the machinery factory clenched their fists and were thinking in their minds.

Some people say the difference is fifty years, some say thirty years, and still others say the difference is even more.

They don't know how much or where the difference is.

But the pace of catching up with the world's advanced technology has never stopped.

I just couldn't see the opponent's back in front of me, so I never had a clear idea.

Yang Xiaotao took a sip of water, picked up the toffee on the table, put it in his mouth and chewed it, thinking about this problem in his mind.

What Alphat said about the most advanced machine tools in Germany was simply deceived.

But when it comes to products produced ten or twenty years ago, Yang Xiaotao is still credible.

Coupled with the study and understanding of mechanical books during this period, Yang Xiaotao also knew that such high-precision semi-automatic machine tools would not mature for many years.

Thinking of this, Yang Xiaotao made a judgment in his mind.

"Chief, if it succeeds, this machine tool can reach the level of developed countries in foreign countries in the 1950s!"

Yang Xiaotao did not give a direct answer, because in his view, the commission for a machine tool does not represent an improvement in overall strength.

If you want to improve the domestic machine tool manufacturing industry as a whole, you need a lot of production and a lot of equipment, which also requires a lot of infrastructure construction.

Nowadays, due to the emergence of the machinery factory Qixing, China can already manufacture some machine tools independently, but most of them still rely on imports.

It can be said that the development of machine tools is very slow.

The domestic development speed cannot even reach the level of Western countries before World War II.

But this machine tool should be at the level of Germany in the 1950s.

Based on this calculation, thirty years of improvement is a conservative estimate.

Of course, the premise is to make it!
The premise is to promote it nationwide!

"Okay. Hahaha. Good!"

Mr. Chen smiled. The situation of national economic and industrial construction was clearly in his mind.

Sometimes I dream about increasing the country’s production capacity and improving machinery standards.

But the reality is often cruel.

The current industrial level of the country cannot even reach that of Goryeo in the east.

"Thirty years, thirty years!"

"This step will shorten the life span by thirty years."

Mr. Chen suddenly stood up, put his hands on his hips, looked at the semi-finished product not far away, and couldn't help but sigh.

When people around him heard the words thirty years, they were inexplicably shocked.

"We can finally see the back of someone's head!"

Mr. Huang suddenly sighed, Mr. Chen looked over, and then the two of them laughed again.

Keep your head down and work hard, and we’ll see each other again, not far away!
"Comrade Yang Xiaotao."

The next moment, Mr. Chen suddenly became serious.

"Chief, please give instructions."

Mr. Chen took two steps forward, raised his arms, and put them on Yang Xiaotao's shoulders.

At this moment, people nearby could clearly feel the change in Mr. Chen's expression, and his eyes were full of tears.

"Chief!"

Mr. Chen's move made Yang Xiaotao feel a little at a loss, and at the same time, a fire arose in his heart.

"I, as an old worker, solemnly request you!"

"Make it happen."

Yang Xiaotao looked at the old man, and then solemnly nodded, "I will live up to my mission."
