After the replacement of several components, the hidden dangers of the original grinder have been solved, and the replaced controller has no major problems as a whole.

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

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

Here, Master Kong was instructed to close the electric switch immediately, and the grinder quickly spun around.

Director Wang immediately had a smile on his face.

In the past, when the grinder was turned on, there would be a screeching sound, and the whole work process was constantly abnormal, and the people around were used to it.

But now, the grinder only makes a very small sound, and it is clear that the parts are grinding together, and they are more precise than before.

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

"Try this."

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

Yang Xiaotao took the outer ring, and now he is considering precision, knowing that being able to achieve this parameter represents success.

"Take a few more, I'm going to try out the standard."

When Director Wang heard this, he immediately asked people to bring the outer ring.

After Yang Xiaotao took it, he handed it to Master Kong and asked him to put it on the grinder, and then he toggled the control wheel, and the grinder began to approach the outer ring.

Then, with a creaking sound, a dent was made on the inside of the outer ring.

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

"It's two millimeters thicker."

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

"This time it's about a millimeter thinner."

When Liu Dehui spoke, his expression was excited.

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

creak

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

"Exactly, in line with the design requirements."

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

"Great, try again."

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

Twenty or thirty in a row, Liu Dehui on the side measured each of them.

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

They all passed.

Liu Dehui and Director Wang are holding the outer ring and watching, each of them is a qualified product, and the error is controlled, this speed, this efficiency, is much stronger than the eighth-level fitter polishing.

That's the power of machines.

A few people were incredulous, and then they were ecstatic.

Director Wang laughed even more, "Lao Liu, are you still worried that there are not enough bearings?" ”

"How much you want, how much you produce, it's all high-quality parts. Now you can rest assured. ”

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

A few people struck while the iron was hot and continued the 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 been marked on the disc.

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

Director Wang looked at the pile of outer rings and inner rings that were soon piled up, and his eyes were happy.

In this way, the pass rate of bearings has been directly increased to more than 90%, saving a lot of resources and improving manufacturing efficiency.

With such a grinding machine, it is worth the efficiency of ten skilled workers.

Even after the operation is proficient, this exchange ratio is still higher.

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

"We will definitely respond 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, it is possible not only to produce bearings, but also to complete other tasks.

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

If it weren't for the fact that they only had one grinder, he would have wanted to leave Yang Xiaotao behind and let him finish all the modifications before leaving.

Similarly, Liu Dehui also thought so on the side.

"Engineer Yang, let's finish dinner and go to the automobile factory."

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

"Director Liu, I'm sorry, Yang Gong will go back to Sijiu City tomorrow, and he will rest in the afternoon, so it's better not to leave the factory."

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

It wasn't until he thought of something that his face relaxed, "It's okay, it's okay if you don't go, this bearing problem has been solved and it has helped us a lot." ”

After speaking, he looked at Yang Xiaotao, "Yang Gong, I have time to come to my automobile factory to sit in the future." I'll go back and tell you the good news. ”

"Please."

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

This time, I didn't eat any food, so I was eager to go back.

The things in the workshop have ended, Director Wang invited Yang Xiaotao to the office, and the task was completed, both of them had relaxed expressions.

"Brother, there's one more thing I need to trouble you."

Director Wang personally poured a jar of hot water, and Yang Xiaotao quickly took it, "Brother, if you have something, just say it, don't be polite." ”

"Okay."

Director Wang leaned on the table and took out a red box of cigarettes from his pocket, on which was engraved a hand holding a white dove of peace, and the words 'Changsheng' appeared impressively.

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

Director Wang took out the matchbox, sneered at it, and handed it to Yang Xiaotao, the two hurriedly lit it, and after a while, there were bursts of smoke in the office.

"Brother, my brother wants you to keep a copy of the drawings of the grinder to the factory, and if there is a problem in the future, it will be repaired."

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

"Rest assured, the credit will be on your head."

"What happened to me, this is it." Yang Xiaotao exhaled smoke and didn't feel anything, "Brother didn't say that I would stay." ”

"As for the other factories, if they need you to arrange it, I have no problem on my side."

"Besides, this thing is useless to me, I'll find a piece of paper in a moment, and I'll draw a copy for you."

"Good, bright, happy."

At that moment, Yang Xiaotao began to draw in the office.

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

It didn't take long for the test results to come in.

The wear and tear of the bearings is also greatly reduced compared to the previous one, 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 will have to be tested in practice.

Liu Dehui asked people to hurry up and test, the observation team will come next month, and they must hurry.

After returning to the office, Liu Dehui regained his composure, thought about it again, and sat at his desk and began to draft this incident.

He said that he asked Yang Xiaotao for credit, then he had to do it.

Similarly, after Director Wang left the office, he came to the conference room, and a person was tinkering inside, also objectively describing what happened.

During the afternoon shift, Yang Xiaotao handed over the drawings that had been compared twice to Director Wang, and then was pulled by Director Wang to the canteen.

This time, it was a farewell ceremony.

The people who ate together were still those people last night, of course, Liu Dehui didn't come, the specifications were the same as last night, but everyone's mood was better than last night.

Yang Xiaotao once again became the focus of everyone's drinking, and at the latest he was thinking about working during the day, and tonight, that is, let go.

"Team leader, this is the train personnel information sent by Section Chief Ding. There are people who got on the bus in Quancheng, and there are people who got on the bus in the middle of the way. ”

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

"Section Chief Ding, your people must always be ready, there is something here, you must fully cooperate, and strive to find out the bottom before dawn."

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

"Okay."

In the room, a group of people began to register and compare the data, looking at them one by one, never missing any details.

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

Section Chief Ding next to him was also smoking a cigarette, and the scar on his face was looming.

Ten o'clock in the evening.

"Team leader, the results are out."

Xiaobo walked over with the comparison data.

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

"Zhao He, male, 24 years old. The treasurer of the brigade department of Wangjiahezi Village, Qihe, proved that the letter was issued by the brigade department, and went to Sijiu City to meet relatives. ”

"Liu Feng, male, 34 years old. The workers of the No. 4 Machinery Factory in Quancheng proved that the letter said that they went to the Sijiucheng Machine Repair Factory to study. ”

"The last one is Ding Junhong, male, 19 years old, who lives in Dashuihe Village, and is a squad leader in the village, proving that the letter was issued by the village brigade department and is going to Sijiu City to find relatives."

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

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

On both sheets of paper, both are women.

"Wang Cuixia, female, 19 years old."

"Li Man, female, 21 years old."

"The letters of proof from both of them were opened by the flour mill, and they went to study at the flour mill in Sijiu City."

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, these people are all investigating."

"It is necessary to investigate not only their origins and family members, but also the unit and reason for issuing the certificate."

"Be careful to investigate secretly, and don't startle snakes."

"Rest assured, we are all trained, well-staffed, and will give you results before dawn."

"Hard."

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

After Team Leader Yu finished instructing, Xiaobo and the others continued to review the materials, and he walked to the phone and reported to the section chief in person.

"Section chief, there is something that needs to be investigated."

"Yes, the reason why these people went to Sijiu City must be investigated, yes, it will be completed before dawn. Well. Good. ”

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 something.

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

"Team Leader Yu, the results are out."

Among the three people investigated, "Zhao He has no problem with Liu Feng." ”

"However, when Ding Junhong was investigating, our people inquired that Ding Junhong was living a better life than other villagers, and he was a little lazy to eat. And it was the elder uncle of their own village who gave him the proof. ”

"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 was sick before leaving, so he gave up the place to Li Man."

"Our man went to the hospital and found that his man was indeed sick."

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

"Ding Junhong is suspicious, and he will pay close attention to it tomorrow."

"Also, go to the hospital and see what is wrong with this man."

Section Chief Ding was stunned for a moment, and then ran out again.

"Team leader, section chief's phone."

"Hey, Chief. You say. ”

"Yes, okay."

Soon, the news from Sijiu City was also confirmed.

After Zhao He's relatives found it, they 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 was decided a week in advance, and Liu Feng planned it eight months ago.

As for Ding Junhong, according to the information they received, his relatives were not found in Sijiu City.

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

The news was summarized together, and Team Leader Yu looked at it again and again.

"Xiaobo, you follow your comrades to investigate Ding Junhong's village elder uncle."

"Yes."

As soon as Xiaobo heard this, he knew the severity and hurried out.

And so, there was another wait.
