Scholars in the courtyard

Chapter 448 Success
After several parts were replaced, the hidden dangers of the original grinding machine were solved, and the replaced controller did not have any major problems as a whole.

Yang Xiaotao walked aside, took off his glasses and put them in his pocket, then nodded to Director Wang, "Director Wang, Director Liu, it should be fine."

After the words fell, Director Wang immediately nodded to Master Kong who was operating the grinding machine.

Here, Master Kong was instructed to turn on the electric switch immediately, and the grinder started to rotate quickly.

Director Wang immediately showed a smile on his face.

In the past, when the grinding machine was turned on, there would be harsh noises, and the abnormal noises continued throughout the working process, and the people around had long been used to it.

But now, the grinding machine only makes a small sound, obviously these parts are grinding together, more precise than before.

From this move alone, it can be seen that the parts replaced by Yang Xiaotao are correct.

"Try this."

Liu Dehui handed a bearing outer ring to Yang Xiaotao, and then reported the parameters.

Yang Xiaotao is holding the outer ring, and now he is considering precision, knowing that reaching this parameter means success.

"Take a few more, I want to try out the standard."

Factory Manager Wang heard this, and immediately asked for the outer ring to be brought over.

After Yang Xiaotao took it, he gave it to Master Kong to put it on the grinder, and then turned the control dial, and the grinder started to approach the outer ring.

Then, with a creaking sound, a dent was ground into the outer ring.

Master Kong stopped, took out the outer ring, and handed it to Liu Dehui for measurement.

"Two millimeters thicker."

Yang Xiaotao listened, took out a new one again, and after readjusting, let Master Kong experiment.

"It's about a millimeter thinner this time."

When Liu Dehui spoke, his expression was excited.

A little bit closer to the goal, this feeling of being close to success is intoxicating.

Squeak
Another one was put away by Master Kong, Yang Xiaotao fine-tuned the turntable, then buckled it, and the machine was polished again.

"Exactly, it meets the design requirements."

Liu Dehui's psychological expectation became a reality, and he immediately shouted.

"Great, try again."

After Yang Xiaotao fixed the scale, Master Kong began to polish the outer ring step by step.

After hitting twenty or thirty in a row, Liu Dehui at the side measured each one.

"This is qualified, this is qualified, and this is also qualified."

They all passed.

Liu Dehui and Director Wang looked at it with the outer ring, each of them was a qualified product, and the error was controlled. The speed and efficiency were much better than those polished by the eighth-level fitter.

This is the power of machines.

After a few people couldn't believe it, they were ecstatic.

Director Wang laughed even more, "Old Liu, are you still worried about not enough bearings?"

"As much as you want, and as much as you can produce, they are all high-quality parts. Now you can rest assured."

Yang Dehui nodded silently, this change represents a big step forward for the car.

Several people struck while the iron was hot and continued to experiment.

By two o'clock in the afternoon, the diameter of the outer ring, the diameter of the inner ring, and the degree of polishing had all been marked on the disk.

You only need to turn the disc to the specified place, and it can be quickly polished to ensure accurate accuracy.

Factory Manager Wang saw that a pile of outer rings and inner rings were quickly piled up, and his eyes opened with joy.

In this way, the passing rate of the bearings is directly increased to over 90%, which not only saves a lot of resources, but also improves the manufacturing efficiency.

Owning such a grinding machine is as efficient as ten skilled workers.

Even after the operation is proficient, the conversion ratio is still higher.

"Comrade Yang Xiaotao, thank you, thank you for your improvement."

"We will definitely report to our superiors, and we must give you credit."

Director Wang said, took Yang Xiaotao's hand and shook it vigorously.

With this grinding machine, not only bearings can be produced, but other tasks can also be performed.

And the defective rate of this part will be greatly reduced.

If they didn't have only one grinding machine, he would have wanted to keep this guy Yang Xiaotao and let him modify everything before leaving.

Similarly, Liu Dehui thought so too.

"Engineer Yang, let's go to the car factory after dinner."

Liu Dehui sent out an invitation at the right time, and Yang Xiaotao was about to agree, but was stopped by Wang Hao at the side.

"Factory Manager Liu, I'm sorry, Mr. Yang will return to Sijiu City tomorrow, and he has to rest in the afternoon. It's better not to leave the factory."

After hearing this, Liu Dehui frowned and looked at Wang Hao.

It wasn't until he thought of something that his face relaxed, "It's okay, it doesn't matter if you don't go, the bearing problem is solved and it will help us a lot."

After speaking, he looked at Yang Xiaotao, "Mr. Yang, come to my car factory when you have time. I'll go back and tell everyone the good news."

"You please."

Liu Dehui winked at Director Wang, who nodded in understanding, then turned and walked out.

This time, I really didn't eat any food, so I hurried back.

The work in the workshop was over, and Director Wang invited Yang Xiaotao to the office. The task was completed, and both of them looked relaxed.

"Brother, there is something else I need to trouble you with."

Director Wang personally poured a jar of hot water, and Yang Xiaotao quickly took it, "Brother, if you have something to say, you are welcome."

"it is good."

Director Wang leaned on the table and took out a red pack of cigarettes from his pocket. It was engraved with a hand holding a white dove of peace, and the word 'Long Victory' appeared impressively.

Yang Xiaotao took the cigarette handed over by Director Wang, and did not rush to light it. He just smelled it and found that the smell of the cigarette was not offensive.

Factory Manager Wang took out the matchbox, opened it with a snort, and handed it to Yang Xiaotao. The two quickly lit it, and after a while, there were bursts of smoke in the office.

"Brother, brother wants you to leave a copy of the drawing of the grinding machine to the factory, so that if there is any problem in the future, it can be repaired."

"Furthermore, with this drawing, the grinding machines in other factories can also make targeted improvements."

"Don't worry, this credit will be recorded on your head."

"What happened to me at the time, so this is it." Yang Xiaotao exhaled the smoke, and didn't feel anything, "I will stay if I don't say anything."

"As for other factories, if they need you to arrange it, I have no problem here."

"Besides, this thing is useless to me. Find a piece of paper later, and I will draw a copy for you."

"Okay, open and bright."

Immediately, Yang Xiaotao began to draw pictures in the office.

On the other hand, Liu Dehui told his workers the good news after returning to the automobile factory, and even handed over the bearings he brought back to the workers for testing.

After a while, the test results came out.

The wear of the bearings is also greatly reduced compared to the previous ones, and because of the uniform specifications, the carrying capacity of the car must be more than the previous 8 tons. As for how much more, it has to be tested in practice.

Liu Dehui asked people to hurry up to test. The observation team will come next month, so we must hurry up.

After returning to the office, Liu Dehui regained his composure, thought for a while, sat at the desk and began to draft the incident.

He said to give Yang Xiaotao credit, so he must do it.

Similarly, after Factory Manager Wang left the office, he came to the meeting room, where he was fiddling alone, and was also describing the incident objectively.

During the afternoon shift, Yang Xiaotao handed over the blueprints that he had compared twice to Director Wang, who was then dragged by Director Wang to the cafeteria.

This time, it will be a farewell ceremony.

Those who ate together were still those people from last night. Of course Liu Dehui didn't come, and the specifications were the same as last night, but everyone was in a better mood than last night.

Yang Xiaotao once again became the focus of everyone's drinking, and at the latest he was thinking about his work during the day. Tonight, he just let go.

"Team leader, this is the information on the train personnel sent by Section Chief Ding. It includes those who got on the train in Quancheng, and those who got on the train on the way."

Xiao Bo put away the sorted out information, Team Leader Yu nodded, "According to what I said, find out the duplicate personnel twice, including those from the same factory and unit."

"Chief Ding, your people must be ready at all times. There is something going on here. You must cooperate fully and try to find out the details before dawn."

"Leader Yu, don't worry, I promise not to delay."

"it is good."

In the room, a group of people began to register and compare the data, looking at each one without missing any details.

Team Leader Yu lit a cigarette, and the smoke drifted over the oval glasses, as if passing by.

Beside him, Section Chief Ding was also smoking, and the scars on his face were looming.

Ten p.m.

"Team leader, the result is out."

Xiao Bo came over with the comparison data.

"These three people bought both yesterday's train tickets and tomorrow's train tickets."

"Zhao He, male, 24 years old. The warehouse manager of the Brigade Department of Wangjiahezi Village, Qihe. The letter was issued by the Brigade Department. He went to Sijiu City to meet relatives."

"Liu Feng, male, 34 years old. A worker at Quancheng No. [-] Machinery Factory. The certificate says that he went to Sijiucheng Machine Repair Factory to study."

"The last one is Ding Junhong, male, 19 years old. He lives in Dashuihe Village and works as a small team leader in the village. The letter of proof was issued by the village brigade. He is going to Sijiu City to find relatives."

Xiao Bo handed the three documents to Team Leader Yu, and at the same time took out two pieces of paper.

"These two people are both from Quancheng Flour Mill."

On both pieces of paper, there are women.

"Wang Cuixia, female, 19 years old."

"Li Man, the female is 21 years old."

"The certification letters of both of them were issued by the flour mill. They went to Sijiu City Flour Mill to study."

Team leader Yu snuffed out the cigarette butts, and there were already a lot of cigarette butts piled up on the ground.

"Section Chief Ding, investigate all these people."

"Not only their origins and family members must be investigated, but also the unit that issued the letter and the reason must be investigated clearly."

"Be careful to investigate secretly, don't startle the snake."

"Don't worry, all of us have been trained and have sufficient manpower. We will give you the results before dawn."

"Hard."

Section Chief Ding ran out with the materials, and soon the people from the security department outside got the task, and after remembering it, they immediately dispersed and disappeared into the night.

After Team Leader Yu finished giving instructions, Xiaobo and the others continued to review the materials, while he himself went to the phone and reported to the Section Chief himself.

"Section Chief, something needs to be investigated."

"Yes, the reason why these people came to Forty-Nine City must be found out, yes, it will be completed before dawn. Hmm. Okay."

After hanging up the phone, Team Leader Yu lay on the bed, took off his glasses, squinted his eyes, and went through the situation again in his mind, for fear of missing anything.

At three o'clock in the morning, Section Chief Ding walked back quickly.

"Group Leader Yu, the results are out."

Among the three people investigated, "Zhao He and Liu Feng have no problem."

"However, during Ding Junhong's investigation, our people found out that Ding Junhong's life is better than other villagers, and he is a bit lazy. And the one who issued the certificate for him was the old uncle of their own village."

"As for the two female comrades, the flour mill did send two people, but Wang Cuixia didn't get on the train yesterday, and the man in the family fell ill before leaving, so the quota was given to Li Man."

"Our people went to the hospital. The man in his family is indeed sick."

Section Chief Ding said, and Team Leader Yu looked at the investigation data again.

"Ding Junhong is suspected, and he will pay close attention tomorrow."

"Also, go to the hospital to see what's wrong with this man."

Section Chief Ding was taken aback for a moment, then ran out again.

"Team leader, section chief call."

"Hey, Chief. Say it."

"Is good."

Soon, the news from Forty-Nine City was also confirmed.

Zhao He's relatives found out and confirmed the facts, and the machine repair factory also confirmed Liu Feng's identity, and the two of them were going to come to Sijiu City. Zhao He made a decision a week in advance, and Liu Feng even planned it eight months ago. of.

As for Ding Junhong, according to the information they received, no relatives of him were found in Forty-Nine City.

In addition, the situation of the flour mill has also been confirmed, but it is true that I received a request from Quancheng Flour Mill four days ago.

The news was gathered together, and Team Leader Yu read it again and again.

"Xiao Bo, follow your comrades to investigate Ding Junhong's uncle, the village chief."

"Yes."

As soon as Xiao Bo heard it, he knew the seriousness, so he hurried out.

So, another wait.
