Scholars in the courtyard

Liu Daming said what was in his heart, but Yang Xiaotao didn't care about it, "Now that our copper-tungsten alloy is provided by the steel factory, the production problem of this turning tool has been alleviated, and this special screw will play an important role in the future production of machine tools. "

"This time, I plan to use this kind of screw for the new rolling mill."

"Determine the model as soon as possible and make what is needed!"

After Yang Xiaotao finished speaking, Liu Daming nodded immediately.

Since Yang Xiaotao didn't care about the machine tool anymore, he had nothing else to say and immediately led a few people out.

Then Yang Xiaotao asked again, and after everyone had no questions, he went to the workshop to get started.

On the way to the workshop, Zhang and Lao also learned the whole story from Yang Youning.

Then there was some disbelief.

"What kind of screws are they really that good?"

Yang Youning smiled and nodded, "This is the work of our employees. We tried it and it turned out to be really good!"

"I told them above, but they don't quite believe it. No, Mr. Xia asked us to experiment again."

"It comes in handy for this experiment!"

The two nodded after listening.

After walking to the workshop, Mr. Zhang felt that this kind of screw was not simple, especially since they used a lot of screws on their aircraft. If the screws were loose, it would be a big or small problem for the aircraft. One screw destroyed an airplane.

"Go and see what's going on with this screw."

"There are a lot of good things here in the machinery factory. If they are useful, we will introduce them!"

Director Zheng nodded seriously after hearing this, "That's right, there are really a lot of good things here!"

"This is the workshop of the R\u0026D Department. It was specially set up by the machinery factory for the R\u0026D Department!"

Yang Youning introduced to Mr. and Mrs. Zhang, "This was originally a logistics warehouse, but the R\u0026D department needs to do research, so we can't always go to the workshop. Why don't we just find a new location..."

With that said, a few people came inside and saw a lot of machines placed inside. Many people were busy working at this moment, and it was much warmer inside than outside. The two of them glanced at the radiator next to them and agreed. Clearly!

"Is this the morning star?"

Not long after he came in, Director Zheng saw the machine tools in the workshop at a glance.

Three in total!

The one at the front is the shining star.

But the two stations at the back are both Morning Stars.

Two Morning Stars!

Director Zheng shouted involuntarily, and then saw everyone around him looking over, and his face turned red for no reason.

When Mr. Zhang next to him shouted out, the words also reached his throat.

However, he held back and did not say anything.

But what I saw in front of me still made me feel uncomfortable.

Their third machine department only has three Morning Star machine tools, which have to be distributed to the factories below, so there is only one for them to use at the headquarters.

More importantly, they regard this machine tool as a treasure, and would not use it unless there are special circumstances.

But now...

There are actually two of them in this workshop!

And they know very well that there must be at least seven or eight machines in the workshop of the machinery factory!

What's more important is that these two machine tools are actually making components. It's really...

What a waste of natural resources!

Things that I regard as treasures are treated as iron here. Really, I feel a little sad!

"This is what people are good at!"

Seeing Director Zheng's surprised look, Mr. Zhang sighed and sighed.

"If people have the ability to make it, they can put it to good use!"

Director Zheng nodded, "I just feel that even if there are so many, they won't give us even one!"

"If we have one more machine, we can improve the progress!"

"makes sense!"

Zhang Lao agreed very much after hearing this.

"Ask me later and give us another one!"

The two of them were talking quietly in the back, and Yang Xiaotao had already started arranging tasks.

After Liu Daming and his people arranged the production of screws, he quickly came over to help!

"Don't be nervous, everyone, do it the same way as before, don't be anxious, and don't be afraid of failure!"

"The production of the rolling mill this time is still different from the three-roll rolling mill last time. Everyone will start after looking at the drawings."

Yang Xiaotao took off his cotton-padded jacket as he spoke, then rolled up his sleeves and prepared to start work.

Zhang Guanyu took the drawings and assigned tasks.

"Gong Liu, please bring someone to get this screw out first!"

Zhang Guanyu found Liu Daming who came in. After hearing this, the latter immediately picked up the drawing and walked to Chenxing Machine Tool aside.

Director Zheng listened on the sidelines and said that he wanted to use Morning Star to drive screws, and suddenly he wanted to speak again.

But Mr. Zhang had already followed him and didn't say much.

However, when they saw the other party actually using the Morningstar machine tool to drive screws, they both looked at each other and saw the helplessness in their expressions.

A small screw was scratched with a knife, and a moment later another knife was scratched on the original basis. In an instant, one thread became two, quick and simple.

On the other side, after Zhang Guanyu divided the preliminary drawings, everyone got into their roles. Yang Xiaotao also came to the machine tool and started to operate the machine tool!

Manufacturing components is tedious and requires time and energy, as well as the pain of failure.

No matter how strong a person is, if he fails too many times, his mentality will be ruined.

So, most workers don't do it all the time.

They also need to rest and adjust.

Of course, there are some people who are special.

Just like Yang Xiaotao.

Throughout the morning, everyone else took a break more or less, but Yang Xiaotao was the only one who kept busy and had no intention of stopping.

"Chief, look!"

On the other side, Director Zheng came to him holding a screw with a little excitement on his face.

Yang Youning looked at it and said with a smile, "This is the special screw we made. It's very good to use!"

After hearing this, Mr. Zhang took the screw and looked at it. Director Zheng explained at the side, "This kind of screw has two kinds of threads. Look here, here..."

"The advantage of this is that when vibration occurs, the occurrence of same-frequency resonance can be reduced."

Yang Youning listened with his ears pricked up. Although Yang Xiaotao had heard that this kind of screws were better than ordinary screws, important parts of the machine tool were now replaced with special screws.

But he had never heard of such resonance at the same frequency.

However, Director Zheng soon explained to him.

"Vibrations have frequencies. When the frequencies are the same, resonance will occur. This is why some sound waves shatter glass and collapse bridges!"

"When this screw is vibrated, it will also vibrate at a certain frequency. In most cases, it will loosen after the vibration!"

"But the situation of these two threads is equivalent to the existence of two frequency bands. It is difficult to produce resonance under one effect, or it requires two effects to occur at the same time. This is more difficult and the chance of occurrence is naturally smaller. "

"In other words, it is very difficult for this kind of screw to be shaken off!"

"Chief, our engines and even airplanes must use these screws!"

The more Director Zheng said, the brighter his eyes became. It is not difficult to design this kind of screw, it just needs to be made.

Just do this, Director Zheng frowned slightly again.

Mr. Zhang looked at the screws in his hands, which were still a little warm after being processed.

He was convinced by Director Zheng's judgment. After all, Director Zheng was an expert in the northwest and was also a well-known 'academic' in the Three Machinery Department.

"Of course, the processing of this kind of screw is not easy."

Director Zheng calmed down and thought about how when he saw the Morningstar machine tool used to process screws, he thought it was a waste of resources and waste.

But after understanding the situation, I felt that only Chenxing could make this kind of screw.

Mr. Zhang looked over again and Director Zheng continued to explain.

“First, the distance between the two threads needs to be exactly the same.”

“Secondly, each thread must remain exactly the same as a whole.

"Finally, the two threads must be different, and this difference must be exactly the same."

"In other words, the accuracy requirements are very, very high."

When Director Zheng said this, he looked at the Morning Star Machine Tool not far away, wondering whether he should use it to drive screws when he went back.

"Yes, Director Zheng is right."

Yang Youning heard Director Zheng's analysis and immediately took what he said to heart.

When people come down from above, he will use this as an example, which will definitely give him more face.

"We have also discovered the advantages of this kind of screw, so we are pushing the machine to use better screws."

"In this way, the quality of the machine can be better improved."

Mr. Zhang nodded silently after hearing this, then looked at Director Zheng, "I'll try it when I get back."

Director Zheng nodded in agreement.

Time flies very fast when busy.

Even if Yang Xiaotao did it himself, the production of this four-roller rolling mill still took two days.

On the morning of the third day, when Yang Xiaotao led people to assemble the rolling mill, many people came to the factory.

The boss of the First Machinery Department, Mr. Huang, is also here this time.

Ever since I learned that Mr. Qin from the Logistics Department had 'stolen' my home, I didn't give Mr. Qin a good look.

That's right, Mr. Qin from the Logistics Department heard that the machinery factory was building a rolling mill again, so he came this morning.

Mr. Qin is here, and Mr. Wang, one of the last four giants, is free.

"Old Huang, tsk tsk, this morning star doesn't even deserve to be in there, tsk tsk."

"It's so rich. It's so rich."

Mr. Wang looked at the machine tools in the warehouse and muttered.

During the last art performance, he told Yang Xiaotao that he would help build a few Morning Star machine tools.

But the other party ignored him at all, and in the end it was useless for him to use his trump card.

Moreover, his trump card was really not around, so the matter was dropped.

But now I see two Morning Stars right in front of me, and they are used for research and development, which means they are usually idle when there is nothing to do.

If you don't need it, give it to him.

Their Seven Machinery Department lacks everything.

What's even more disgusting is that one of them is still driving screws.

This wasteful thing, why do you need such a good machine tool to drive screws?

Tell him how many screws you want, and he will tell the factory below to send them to him immediately.

"Old Qin, where are the things? Don't fool people."

Mr. Huang ignored Mr. Wang's thoughts and looked at Mr. Qin beside him.

At this moment, Mr. Qin was looking at the rolling mill assembled by Yang Xiaotao. It looked different from the three-roller one.

Moreover, it is said that this was designed by Yang Xiaotao himself, while the three-roller was only designed by the R\u0026D department of the machinery factory.

He knew the difference.

I also felt a little regretful in my heart. I had known it would come a day later, so why was I in such a hurry?

Now, if the Third Machinery Department uses such a good rolling mill, the progress will not be greatly improved?

The most important thing is, quality.

"I've brought them all, don't worry, they will definitely be indispensable."

Old Qin said without replying.

If Mr. Qin had this attitude before, Mr. Huang would have gone up to have a good 'communication'.

But now, he was happy and didn't care about it anymore.

Besides, after all, they didn't suffer a loss.

Looking at Yang Xiaotao in the field, Mr. Huang's mouth slightly raised.

"Old Huang, Old Huang, let's discuss something."

"Old Huang, we are brothers as close as a family."

The voice of Mr. Wang came again from the side, and Mr. Huang directly measured his body and chose to ignore it.

Damn, these guys are always targeting him.

They really think they are landlords, but even landlords don't have surplus food.

If it doesn't work, I'll just live here.

An idea suddenly popped up in Mr. Huang's mind, and the more he thought about it, the more he thought about it.

Anyway, there is Lao Xia in the First Ministry of Machine Building, and he is in this machinery factory.

Look at this environment, listen to the wonderful sound of the machine, the enthusiasm here is also high, and there are always surprises.

And the food is not bad.

'Is this considered an early retirement day? '
