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 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?"

"Temperature!"

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

“What does the temperature matter?”

Mr. Huang 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. At this time, 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 requirements are 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 would solve it.

"Quick, light the brazier!"

"Get 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 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. Okay!"

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 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 me 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 clearly felt the change in Mr. Chen's expression, and his eyes were filled with 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."
Chapter completed!
