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

Seeing that Yang Xiaotao finished the fourth part, taking advantage of the rest and drinking water, Yang Youning immediately stepped forward and said with concern.

"The boiled bones made in the cafeteria, as well as pies, you can eat some to supplement first!"

Yang Xiaotao looked at Liu Daming and the others who were eating on the side, felt the physical condition, and then shook his head, "No, I feel good now, let's go for a while." ”

Yang Xiaotao opened his mouth to refuse, but Yang Youning didn't say much, picked up the cake and stood aside to watch.

The people around them left and returned, still piling up the warehouse.

Next to it, Liu Daming drank the bone broth in the rest place, solved his personal problems, and walked to the machine.

Eat and drink to your heart's content, and start working again.

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

High-intensity work, high mental concentration, and physical energy consumption are not decimals.

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

I don't know when, Xia Lao and Sun Lao from the First Machine Department came to the scene, accompanied by Liu Huaimin and Yang Youning.

Several people saw that Yang Xiaotao was resting, and they didn't come forward to disturb.

The eyes of the people around him looked at Yang Xiaotao with admiration.

From the beginning of the morning to the present, Yang Xiaotao has made a total of six parts.

It doesn't seem like much, but compared to others, so far only Liu Daming and Liu Gong have made a qualified one.

The parts made by others are not perfect in accuracy testing.

And the one made by Liu Gong also cost three materials.

It's like Yang Xiaotao, over and over again.

The efficiency and success rate are simply unbelievable!

So much so that in the end, everyone didn't dare to waste the material.

"Lao Liu, rest!"

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

Liu Daming showed a wry smile on his face, "It's old, it's useless!" ”

The 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 listened to it and raised their heads again.

As night fell, the machine shop became more and more lively.

Many people who leave work do not leave the factory, but stay on the shop floor, outside the warehouse, as if waiting for something.

At the gate, Liang Zuoxin had just received a notice that the superior leader was coming, so he hurriedly sent someone to the door to guard.

Not long after, two cars appeared on the road and soon came to the door.

"Chief!"

Liang Zuoxin saw the person sitting in the car and immediately stepped forward to see it, the person who came nodded, and then the car entered the machinery factory.

The car behind followed closely.

"Look at the gate!"

Liang Zuoxin gave an instruction, immediately got on the motorcycle, and followed behind the convoy.

The car stopped, and Liang Zuoxin immediately guided a few people to get out of the car and walk to the warehouse.

At the gate, Xia Lao and Liu Huaimin had been waiting for a long time, and when they saw Huang Lao and Chen Lao who was following behind, they immediately stepped forward.

"Chief!"

"Leader!"

A few people have seen it, Chen Lao tightened the cotton clothes on his body, and asked as he walked inside, "What step is it now?" ”

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

"One of the hardest control bearings is being done!"

"Now it's the second attempt!"

Xia Lao explained that most of the day's work was basically watched here, but he didn't feel tired.

The mind is involved in success and failure again and again, and even time feels faster.

Of course, compared to Yang Xiaotao, they are all relaxed!

Chen Lao didn't say much when he heard this, and walked quickly through the crowd to the innermost.

What caught my eye was Yang Xiaotao sitting on the side and fiddling with the workpiece on the ground.

The people around him wanted to remind him, but he was stopped by Chen Lao raising his hand.

"Chief, what you did just now is not qualified."

"Xiao Tao is checking the problem."

Chen Lao nodded, and then looked to the side, where parts were being installed in the busy crowd, and an unseen outline of a machine tool was rapidly taking shape.

"Chief, this time, thanks to Xiao Tao."

Xia Lao whispered on the side, "There are thirteen core components, and he has completed eleven by himself!" ”

Elder Sun also nodded, "This kind of accuracy requirement is beyond the ability of ordinary eighth-level workers." ”

"I guess I can't find a second person in the country!"

Huang Lao took a deep breath, "One such person is the luck of our country." How many more do you want? ”

"That's just as well!"

Chen Lao didn't say much after hearing it, but he was thinking in his heart that if such a high-precision machine tool was made, it would have an impact on the domestic manufacturing industry.

How many years will it drive the machinery industry forward?

Since the implementation of the technical blockade of the country abroad, the domestic machine tool industry has lagged behind for at least 50 years.

Fifty years, the gap between two generations.

Moreover, there are too many constraints on domestic development, and this gap cannot be said to catch up, but will only get bigger and bigger.

That's why they give the task to each machine tool manufacturer to research better machine tools to shorten the gap.

But the result.

Many machine tool factories have tried, and the best is only a level with Daystar.

It can be seen how difficult the technical barriers are.

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

The youth in front of them is their last reliance.

"It should be ten years!"

Chen Lao tried his best to think better, to think boldly, and then, his heart was full of expectations.

Huang Lao's eyes were burning, and he tried to suppress the excitement in his heart, but he had to suppress it and keep quiet.

The people around him didn't dare to talk about it, even if they had all kinds of ideas in their hearts, they could only hold back.

A group of people were staring at Yang Xiaotao.

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

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

Two symmetrical bearings, no problem.

The materials used, there are no problems.

Where exactly does it appear?

The accuracy of the production should meet the requirements!

How could it go wrong?

I also made two mistakes in a row, which shouldn't have been!

Studied but cannot comprehend.

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

The night was cold, and he only wore an autumn coat and a shirt, and it was still too hot when he was working, and it was a little cold to sit at this time.

Cold?

Suddenly, Yang Xiaotao immediately took off his gloves and touched the surface of the parts with his hands, which was cold.

This is a block of copper-tungsten alloy.

Yang Xiaotao didn't know what the expansion system of this alloy was, but he understood a truth.

Thermal expansion and cold contraction.

"Hahaha, no wonder, no wonder!"

Suddenly, Yang Xiaotao chuckled.

The people around were all curious, and Chen Lao and a few people stepped forward.

Looking up and seeing everyone, Yang Xiaotao got up and slapped the parts, and then smiled, "Understood, understood!" ”

"Got what?"

Yang Youning asked anxiously.

Yang Xiaotao nodded to Chen Lao and the others, and when he saw that everyone was curious, he immediately looked to the side, "How many degrees is it now?" ”

"How many degrees?"

"Temperature!"

When people heard this, they immediately asked, and some people ran out to check the thermometer.

"What does it matter about temperature?"

Huang Lao asked on the side.

"Chief, this metal has a characteristic, thermal expansion and cold contraction!"

Yang Xiaotao said with a smile, Chang Mingjie and the others on the side hung their heads and said with their mouths oops.

Huang Lao and the others also reacted, and at this time, there was a shout from outside, "Fahrenheit forty-two!" ”

Then I saw a man holding the thermometer to him.

Yang Xiaotao glanced at it, and when converted, it was less than six degrees!

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

Yang Youning listened, and didn't think much about it, since he found the problem, then solve the problem.

"Quick, raise the brazier!"

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

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

"Turn on the lights!"

Everyone cheered and cheered.

At this time, Yang Xiaotao came to the rest place and began to replenish his strength.

Old Chen sat on the side, his demeanor kind.

"Xiao Tao, you give me an accurate sentence, with this machine tool, how much can we shorten the gap with foreign countries?"

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

The people in the machinery factory clenched their fists even more, thinking in their hearts.

Some people say that it is 50 years worse, some say 30 years, and some people say that it is even worse.

They don't know how much worse it is, and where it is.

But catching up with the world's advanced footsteps has never stopped.

It's just that I can't see the back of the other party in front of me, so I haven't had a clear concept.

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

What Alpha said about the most advanced machine tools in Germany at present was purely fooled.

But if you want to talk about the products of 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 knows that this kind of high-precision semi-automatic machine tool has not matured for many years.

Thinking of this, Yang Xiaotao had a judgment in his heart.

"Chief, if it can be successful, this machine tool can reach the level of the fifties in foreign developed countries!"

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

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

Nowadays, because of the emergence of the machinery factory Daystar, it has been able to 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 pace of domestic development is not even at the level of Western countries before World War II.

But this machine should be on the level of the German fifties.

In this way, an increase of 30 years is a conservative estimate.

Of course, the premise is to make it!

The premise is to promote it to the whole country!

"Good. Hahaha. Good! ”

Chen Lao smiled, the situation of national economic construction and industrial construction was clear in his mind.

Sometimes I dream of increasing the country's production capacity and improving the level of machinery.

But the reality is often harsh.

The current level of industry in the country cannot even be reached in Goryeo in the east.

"Thirty years, thirty years!"

"This step has been shortened by 30 years."

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

The people around heard the words of thirty years, and they were inexplicably shocked.

"Let's finally see the back of someone's head!"

Huang Lao suddenly sighed, Chen Lao looked over, and then the two laughed again.

Immerse yourself in hard work, look up and see each other, not far away!

"Comrade Yang Xiaotao."

The next moment, Old Chen suddenly became serious.

"Chief, please instruct."

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

At this moment, the people who were close to clearly felt the change in Old Chen's expression, and his eyes were full of tears.

"Chief!"

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

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

"Make it."

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