Chapter 1603 Special Thread

After handing the design to Liu Daming, Zhang Guanyu and others, Yang Xiaotao no longer participated in the production of the rolling mill, but inspected the situation in the workshop accompanied by Chang Mingjie.

"How is the production of Morning Star now?"

The two walked to the innermost Morning Star production line, and Yang Xiaotao asked casually while looking at the busy workers.

Hearing Yang Xiaotao's question, Chang Mingjie smiled bitterly.

"One machine a month is good now."

Yang Xiaotao frowned, "So few?"

Chang Mingjie nodded.

"Since you made ten machines in one go last time, only eight have been produced so far."

"Half of them were made by Engineer Liu and his team."

Chang Mingjie said aside, feeling a little uneasy.

Recently, the defective rate of their second workshop has been quite high.

Especially the production of Morning Star, which consumes a lot of materials, even Director Yang has opinions.

Yang Xiaotao did not see Chang Mingjie's embarrassment, but looked at the busy workers.

Because Yang Xiaotao mentioned to Liu Huaimin last time that the popularization of machine tools requires high-precision machine tools, but if you want to improve it further and get a better machine tool than Morning Star, you can't do without human operation.

You can't use ten or eight Morning Stars to make Morning Star.

That's unrealistic.

But you can use people to improve the accuracy of machine tools.

Therefore, the machinery factory has not relaxed the technical requirements for factory workers, but has become more strict.

Only when subsequent talents keep up can we lay a solid foundation for future machine tool research.

And how to improve the ability of talents?

In addition to talent, it is practice.

At present, the lowest level on this production line is a sixth-level fitter, and there are even a few eighth-level workers.

"Are these people transferred here?"

Chang Mingjie nodded quickly, "Yes, they are all elites who have been transferred, and there is a lot of room for improvement in technology!"

"That's good!"

"You don't have to rush, give your comrades enough time to grow."

"Don't be afraid of waste, as long as we make one, we will be successful."

Yang Xiaotao looked at everyone with more expectations in his eyes.

These people are the treasures of the machinery factory!

Chang Mingjie nodded.

"It's just some waste alloy!"

Yang Xiaotao smiled and said, "It's okay, it's okay, it's used anyway!"

Hearing Yang Xiaotao say this, Chang Mingjie's worries were put down.

The two were walking, and then they saw a person coming out from the side, walking quickly.

"Mr. Yang?"

The person suddenly stopped in front of Yang Xiaotao, and then saw Yang Xiaotao, and his face showed joy.

Yang Xiaotao saw the person and stopped, "Old Guo!"

The person was Old Guo who was pulled into the R&D department by Yang Xiaotao. The relief on the friendship pot was his masterpiece.

Based on the plan to recruit special talents, many people in various workshops of the machinery factory were pulled into the R&D department.

Just like the hollowing technical talents in the fourth workshop, the welding talents in the eighth workshop, and so on.

Of course, this is only for the machinery factory. As for other branches or other factories, as long as it is possible, they will recruit people to the R&D department.

So, there are quite a few people in the R&D department now.

Of course, some people are just in name only.

After all, the workshop still needs them to work.

The advantage of being in name only is that they can get an extra five yuan subsidy every month.

Those with special skills are very active in this regard.

At this time, in the cold weather, Lao Guo rolled up his sleeves, holding two long and thin screws in his hands, and the two tufts of white mustaches on his lips jumped, looking particularly excited.

"Mr. Yang, when I heard that you were back, I wanted to find you."

"Originally, I didn't bother you yesterday, but you were so busy that I didn't bother you."

"I didn't expect you to come to the workshop today, haha, that's great."

Lao Guo is not young, but it may be related to his profession. He likes to be straightforward when he sees Yang Xiaotao. He is very familiar with him and says whatever he wants.

"Old Guo, what do you want to do with me?"

Yang Xiaotao was not polite and asked directly.

"Hey! Mr. Yang, good stuff. Definitely good stuff!"

As he said that, he stretched out his dark hand and handed the two finger-sized screws in front of him to Yang Xiaotao.

Yang Xiaotao reached out to take it, and Chang Mingjie, who was standing beside him, was also curious and took one to look at.

Old Guo clapped his hands, looking a little conceited, but his eyes showed expectation.

Yang Xiaotao looked at the screw in his hand, and at first glance it was just an ordinary screw.

But after looking more carefully, he felt that it was different from ordinary screws.

Chang Mingjie reached out and touched it, then looked at Yang Xiaotao, and then looked at Old Guo who was waiting for praise, and then spoke.

"Isn't this just an ordinary screw? And, you hit it too roughly, it's not dense at all."

As he said that, he returned the screw to Old Guo, feeling a little unhappy.

That is to say, the other party is from the R&D department, so he can't say anything.

But in fact, most people in the R&D department are capable, no, it should be said that they are all capable, but they are not using them in the right way.

Lao Guo took the screw and didn't say anything, but looked at Yang Xiaotao.

In his heart, Yang Xiaotao is the most powerful person in this machinery factory.

He can definitely see the doorway.

"No, this screw is not ordinary!"

Yang Xiaotao looked at it for a while, and touched it with his hand, his eyes solemn.

"Why is it different?"

Chang Mingjie also realized that if it was an ordinary screw, the other party would not come so happily.

Yang Xiaotao looked at Lao Guo, and then laughed, "Lao Guo, take out the bolts you hid."

Hahaha

"It's really Mr. Yang, worthy of being the most powerful engineer in our machinery factory."

"Awesome, it's awesome!"

He stretched out his hand and gave a thumbs up.

On the other hand, he took out two bolts from his trouser pocket and handed them to Yang Xiaotao.

"Boss Yang, this is the screw I made. Look inside, it is a special thread formed by two superimposed threads."

"I tried it on the machine tool, this screw is more durable and wear-resistant."

"If you don't believe me, I'll take you to see it."

"It's still strong now that I used it last time."

After Lao Guo finished speaking, Yang Xiaotao immediately understood why there were two kinds of threads on the screw.

One is thin and tall, and the other is thick and short, but they are arranged in order as a whole.

It is obviously a thread that has never appeared before.

"Lao Guo, are you kidding?"

Chang Mingjie on the side also realized the benefits of this screw.

Lao Guo patted his chest, "Needless to say, it must be true!"

He then explained what happened, "During the winter months before the New Year, I was helping to look after the machine tool. Later I found that the machine tool had been used for a long time, and the screws would loosen due to the vibration of the machine."

"I thought, can I make a screw that will not loosen."

"Then I thought about it."

"I thought about it for a few days, and then it was my old profession that reminded me."

Speaking of this, Lao Guo showed a hint of pride on his face.

"When I went back to do the relief, I was hammering it, thinking that if the hair of this character is all the same, no matter how thin it is, it will still look like one layer."

"It doesn't feel anything when you touch it."

"On the contrary, it's the kind of high and low, uneven, that feels obstructed when you touch it."

"So."

"So you made this kind of thread, right?"

Chang Mingjie couldn't listen anymore. This old Guo has been a person in the R&D department. He used to be so capable, but why is he still talking in a slick way and talking endlessly.

When Lao Guo heard what Chang Mingjie said, he immediately nodded, "Yes, so I tried to make a few screws."

"I didn't expect it to be useful."

Yang Xiaotao picked up the screw and silently felt the thread.

To be honest, in his professional eyes, these two screws are indeed rough, and even a fitter apprentice can make better than him.

But the way these two threads are superimposed, let alone a fitter apprentice, even he, an eighth-level fitter, has never thought about this aspect.

"Let's go and have a look."

A gleam of light flashed in Yang Xiaotao's eyes. If it works, it will greatly improve the design of machine tools and the performance of some special machines.

"Okay."

Old Guo smiled and hurriedly took Yang Xiaotao and the others to the machine tool production nearby.

When they came to a semi-automatic Venus machine tool, the workers who were operating it saw the factory's general manager Yang and the supervisor coming over, and thought something had happened. They hurriedly stopped the machine tool, and their faces were a little nervous.

But when the three of them came in front of him, Old Guo pointed to the two screws under the machine tool.

"I drove these two screws out. At that time, the screws were easy to loosen, so I found a new screw and changed it. Now you see, it doesn't move at all."

Old Guo pointed to the place where the machine tool was fixed, and Yang Xiaotao squatted down to check.

"You work normally."

Chang Mingjie said, and everyone realized that he was not here to find them this time, so they continued to work.

Yang Xiaotao stared at the fixed screws. When the machine tool processes parts, the whole will produce a certain degree of vibration, and the fixed screws will tremble with it.

Although it is not noticeable in a short time, it is easy to loosen over time.

This situation is not only common in machine tools, but also in rolling mills in the past.

"How long has this screw been used?"

Yang Xiaotao asked casually while asking people to stop.

Lao Guo thought about it and said, "About a month."

"I dug this bolt out myself, so it may not be very compatible."

Lao Guo explained again, but Yang Xiaotao looked up and said, "Give me a wrench and pliers."

The worker stopped the machine tool and someone handed the tool to Yang Xiaotao.

After Yang Xiaotao took it, he first tried a normal screw and then tightened this special screw.

In terms of strength, Yang Xiaotao obviously felt that the latter was more struggling.

However, Yang Xiaotao did not rush to draw conclusions.

"Old Chang, I remember that our factory's assessment team has a screw torque test. Please ask someone to come."

Chang Mingjie immediately agreed.

After a while, two people ran in from outside, led by Guo Liang, the leader of the assessment test team.

Coming closer, Guo Liang greeted Yang Xiaotao.

When Yang Xiaotao took the first-level fitter exam, he was in charge of the assessment.

But so many years have passed, Yang Xiaotao has become General Manager Yang, and he is still the leader of the assessment team.

"Team Leader Guo, measure the torque of these two screws."

Yang Xiaotao said directly, and Guo Liang nodded.

As early as when he received the news, he had already brought the equipment.

Knowing that it was to test the torque of the screws, he took out the torque wrench and tested it seriously.

After the original screw test was completed, Yang Xiaotao looked at the scale on the wrench and pointed to five.

After changing the screws with special threads, Guo Liang was curious but tested them seriously until he heard a click. Yang Xiaotao hurried over to check. Eleven!

Yang Xiaotao looked serious and Chang Mingjie's eyes widened.

Even Guo Liang was a little unconvinced, and then he tested it again. It was still eleven.

The only one who didn't change his expression was Lao Guo.

Of course, he was not calm, but he didn't know what the number on the wrench meant.

"Mr. Yang, that's right, it's eleven."

Yang Xiaotao laughed immediately after hearing this, and then came to Lao Guo and patted him on the shoulder gently, "Comrade Lao Guo, congratulations, you have made a contribution."

Yang Xiaotao laughed, and Lao Guo also laughed after hearing this.

"It doesn't matter whether it is a contribution or not, as long as it helps the machinery factory."

"Help, yes, definitely."

Yang Xiaotao said affirmatively, and then added, "Your invention may be useful to the whole country."

Lao Guo didn't care after hearing this.

In fact, the original vision was that I didn’t want to follow Lao Liu to look at the machine tool.

But if the machine tool is not optimistic, it can really go wrong.

Now that we have this kind of screw, we don’t have to look at the machine tool anymore.

Lao Guo was very happy, because now he has time to slack off.
