Scholars in the courtyard

After replacing several parts, the hidden dangers of the original grinder were solved, and the replaced controller did not cause any major problems overall.

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

After finishing his words, Director Wang immediately nodded to Master Kong who was operating the grinder.

Here, Master Kong received the instruction and immediately turned on the switch, and the grinder started rotating rapidly.

Director Wang immediately smiled on his face.

In the past, when the grinder was turned on, there would be a harsh sound, and the noise was constant throughout the working process, and people around it had long been used to it.

But now, the grinder only makes a small sound. It is obvious that these parts are running together and are more precise than before.

This move alone showed that the parts Yang Xiaotao replaced were correct.

"Try this."

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

Yang Xiaotao held the outer ring. What he was considering now was precision. He knew that being able to reach this parameter would mean success.

"Get a few more, I want to test out the standard."

Director Wang heard this and immediately asked someone to bring the outer ring.

After Yang Xiaotao took it, he handed it to Master Kong and placed it on the grinder. Then he turned the control panel and the grinder began to approach the outer ring.

Then with a squeaking sound, a dent was made inside the outer ring.

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

"Two millimeters thicker."

After hearing this, Yang Xiaotao took out a new one, readjusted it, and asked Master Kong to experiment.

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

Liu Dehui looked excited when he spoke.

Getting closer to the goal little by little, this feeling of being close to success is intoxicating.

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

"Just right, 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.

Twenty or thirty were beaten in a row, and Liu Dehui on the side measured each one.

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

All of them passed.

Liu Dehui and Director Wang were holding the outer rings and looking at them. Every one of them was a qualified product, and the error was controlled. This speed and efficiency were much better than those polished by an eighth-level fitter.

This is the power of machines.

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

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

"As much as you want, we will produce them for you, and they will all be high-quality parts. Now you can rest assured."

Yang Dehui nodded silently. This change represented a big step forward for the car.

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

By about two o'clock in the afternoon, the diameter of the outer ring, the diameter of the inner ring, and the degree of polishing were all marked on the disc.

You only need to turn the disc to the specified place to quickly polish and ensure accurate accuracy.

Factory Director Wang saw how quickly a pile of outer and inner rings were piled up, his eyes widening with joy.

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

Having such a grinding machine can match the efficiency of ten skilled workers.

Even after you become proficient in the operation, the exchange ratio is still higher.

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

"We will definitely report it to our superiors and ask for credit."

Director Wang said, taking Yang Xiaotao's hand and shaking it vigorously.

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

Moreover, the defective rate of this part will be greatly reduced.

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

Similarly, Liu Dehui thought the same thing on the side.

"Engineer Yang, let's finish our meal and go to the automobile factory for a walk."

Liu Dehui issued 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, but Mr. Yang will go back to Sijiu City tomorrow. He needs to rest in the afternoon, so 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 expression relaxed, "It's okay. It doesn't matter if you don't go. Solving the bearing problem also helps us a lot."

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

"As you please."

Liu Dehui winked at Factory Director Wang, who nodded to express his understanding, then turned and walked out.

This time I really didn’t even eat anything, so I went back eagerly.

Things in the workshop were over. Factory Director Wang invited Yang Xiaotao to the office. The task was completed, and both of them had relaxed expressions.

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

Factory Director Wang poured a jar of hot water himself, and Yang Xiaotao quickly took it, "Brother, if you have anything to say, you're welcome."

"good."

Factory Director Wang leaned on the table and took out a red cigarette box from his pocket. On it was engraved a hand holding a white dove of peace, and the words 'Long Victory' appeared clearly.

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 strong.

Director Wang took out the matchbox, opened it and handed it to Yang Xiaotao. The two of them quickly lit it. After a while, bursts of smoke appeared in the office.

"Brother, I want you to leave a copy of the drawings of the grinder to the factory so that if any problems arise in the future, they can be repaired."

"Furthermore, with this drawing, grinders in other factories can also make targeted improvements."

"Don't worry, this credit will be credited to you."

"What happened to me at that time? It turns out this is it." Yang Xiaotao exhaled the smoke and didn't feel anything. "I will stay even if I don't tell you."

"As for other factories, if they need you, just make arrangements. I have no problem here."

"Besides, this thing is of no use to me. I'll find a piece of paper later and I'll draw a copy for you."

"Good, open and happy."

At that moment, Yang Xiaotao started drawing pictures in the office.

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

After a while, the test results came out.

The bearing wear is also greatly reduced compared to the previous one, and because the specifications are unified, the car's load capacity is definitely more than the previous 8 tons. As for how much more, actual testing is required.

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

After returning to the office, Liu Dehui regained his composure, thought for a while, and sat at his desk to start drafting what happened.

He said to ask for credit from Yang Xiaotao, so he must do it.

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

During the afternoon shift, Yang Xiaotao handed over the twice-compared drawings to Director Wang, and was then dragged toward the cafeteria by Director Wang.

This time, treat it as a farewell ceremony.

The same people who ate together were the same people as last night. Of course Liu Dehui didn't come. 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. At the end of the day, he was still thinking about his work during the day. Tonight, he just wanted to let go.

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

Xiaobo put the compiled information away, and Team Leader Yu nodded, "Follow what I said, find two duplicate people, including those from the same factory and unit."

"Chief Ding, your people must always be prepared. If something happens here, you must cooperate fully and try to find out the details before dawn."

"Team Leader Yu, don't worry, I promise there won't be any delays."

"good."

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

Team leader Yu lit his cigarette, and the smoke drifted from his oval glasses like a passing cloud.

Next to him, Section Chief Ding was also smoking, with scars on his face looming.

Ten p.m.

"Team leader, the results are out."

Xiaobo came over with the comparison data.

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

"Zhao He, male, 24 years old. Warehouse manager of the Brigade Headquarters in Wangjiahezi Village, Qihe. The letter of certification was issued by the Brigade Headquarters. He went to Sijiucheng to meet relatives."

"Liu Feng, male, 34 years old. Worker at Quancheng No. 4 Machinery Factory. The letter of certification states that he went to study at the No. 4 Jiucheng Machinery Repair Factory."

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

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

"Both these two people are from Quancheng Flour Mill."

On both pieces of paper, there are women.

"Wang Cuixia, female, 19 years old."

"Li Man, female is 21 years old."

"Both of them have certificates from flour mills, and they went to the Sijiucheng Flour Mill to study."

Team leader Yu put out his cigarette butts. There were already many cigarette butts piled on the ground.

"Chief Ding, investigate all of 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 and don't alert others."

"Don't worry, we are all trained and have enough manpower. We will give you the results before dawn."

"Hard."

Section Chief Ding took the materials and ran out, and soon the people in the security department outside were given the task. After remembering it, they immediately dispersed and disappeared into the night.

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

"Section Chief, there is something that needs investigation."

"Yes, the reason why these people came to Sijiu City must be found out. Yes, it must 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 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 and Liu Feng have no problem."

"However, when Ding Junhong was investigating, our people found out that Ding Junhong's life was better than that of other villagers, and he was a bit too lazy to work. And the person who issued the certificate to him was their village elder uncle."

"As for the two lesbians, the flour mill did send two of them, but Wang Cuixia did not get on the train yesterday. The man at home fell ill before leaving, so she gave her place to Li Man."

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

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

"Ding Junhong is suspicious, so we should pay close attention tomorrow."

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

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

"Team leader, section chief's phone number."

"Hey, section chief. Tell me."

"Is good."

Soon, the news from Sijiucheng was confirmed.

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

As for Ding Junhong, according to the information they received, no relatives of his were found in Sijiu City.

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

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

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

"yes."

When Xiaobo heard this, he understood the seriousness and hurried out.

So, another period of waiting.
