After the screw was installed in place, Jiang Yan re-inspected the entire machine.

Turning the screw rod, Jiang Yan listened carefully, and there was not a trace of noise coming out of the screw rod.

Jiang Yan turned his head and gave a thumbs up to Sun Deshui, who was helping beside him.

Then things are relatively simple, and the remaining parts can be drawn and installed according to the step-by-step drawings.

However, among them, perhaps only Jiang Yan himself is the most distracted.

He has to carefully scrutinize the installation situation step by step against the drawings to see if the best installation state is achieved, if not, he needs to re-scrutinize.

So today, he has Shen Gong by his side, as well as two other engineers to assist.

When encountering a place where the installation is not in place, several people stop to discuss and brainstorm.

The drawings were changed by them, and in the discussion of several of them, a whole set of such installation steps was discussed.

There are many pieces of scratch paper, as long as there is text and scratch paper, they are all collected by Guo Jianjun and stored carefully.

Due to the long installation time, Director Zhao has already taken his secretary to deal with other work, and before leaving, he specially told Guo Jianjun to take care of Jiang Yan and Minister Hong.

After more than three hours of installation, the entire finishing machine has been fully assembled.

At this time, the finishing section machine has been removed from the stains and a lot of new parts have been added, which looks like a completely new machine.

"Engineers, workers, Minister Hong, isn't it time to eat something?"

Seeing that the precision section machine had been assembled, Guo Jianjun hurriedly stepped forward with a lunch box.

Hearing Guo Jianjun's words, Jiang Yan took out the watch that he had put in his pocket when he was working and took a look.

It's already half past two in the afternoon, and I've been working for more than six hours since I knew it.

To be honest, I was really hungry after this stop.

So Jiang Yan hurriedly beckoned the others who had stopped working to come over for dinner.

Jiang Yan took the aluminum lunch box handed over by Guo Jianjun and opened it and looked at it.

The lunch box is divided into two pieces, one side is the vegetable and the other is the white rice.

The dish is mainly cabbage and potatoes, but there are a few pieces of braised pork with bright colors on top, which is very appetizing to look at.

"Jiang Gong, you tested it just now, there is no problem!" As soon as Jiang Yan took a bite of rice, Shen Gong brought the lunch box to him.

"There should be no problem, after a while, let's finish eating, start and test, and if there is a problem, we will improve it on the spot."

Jiang Yan swallowed the rice in his mouth before he spoke.

"Jiang Gong, do we need to sort out the installation steps we have perfected today?" At this time, Wang Tianlai also came to Jiang Yan with a lunch box.

"It's to sort it out, these are first-hand information, and it will be of great help to the installation or the main one in the future."

"Then I'll sort them out and show them to you."

When Jiang Yan heard Wang Tianlai's words, he looked up and found that this kid was a chicken thief, but this little thing was nothing to Jiang Yan.

"No problem, after the information is sorted out, I will add the names of several of you to report it."

After eating, Jiang Yan drank another large glass of warm water, and after smoking a cigarette outside the workshop, he walked into the workshop again.

The people who were resting in the workshop all stood up one after another when they saw Jiang Yan coming in, waiting for Jiang Yan's command.

"Old Sun, go get a seamless steel pipe."

"Wang Gong, prepare for the record."

After arranging the people, Jiang Yan came to the Jingduan machine.

He skillfully connected the finishing machine to the power supply and pressed the start button.

At this time, Sun Deshui handed the seamless steel pipe to the lathe waiting there, and he skillfully put the steelless pipe into the finishing machine.

Then he installed the corresponding knife on the knife holder, and after the test knife was debugged, under the eyes of everyone, he started the machine and began to carve the gun line in the seamless steel pipe.

After a screeching sound, the turner stopped the machine and removed the barrel from the machine.

He walked down with the barrel that had been carved on the inside of the barrel and handed it to Jiang Yan.

Jiang Yan picked up the tool for measuring the internal line of the barrel.

Seeing Jiang Yan testing, everyone's hearts lifted.

Everyone in the workshop seemed to be breathing carefully, afraid that if they breathed a little more, it would affect the measurement.

"Excellent. Just a trace. ”

After hearing these two words from Jiang Yan's mouth, everyone cheered, even Director Zhao, who came over later.

Jiang Yan said a trace of it, representing the tolerance generated in the production process of the parts, this tolerance value is already a rather terrifying data for the current machine, this data is almost exactly the same as the tolerance of the new machine, which also means that Jiang Yan and they have completely repaired this fine section machine at this time.

"Master, how did you feel about starting the machine just now?"

Hearing Jiang Yan ask, the lathe carefully recalled.

"The control of the finishing section machine is very sensitive, especially the time of turning the tool and pushing and pulling the screw, without a trace of stagnation."

Hearing him say this, Jiang Yan nodded with satisfaction.

"Are all the drawings in order?" Jiang Yan turned his head and asked Guo Jianjun, who was following him.

"It's sorted out, all the drawings are here with me, as long as it's paper with words, I'll pack it up and send a special person to take care of it."

Drawings are the most important thing, with these drawings plus the installation steps discussed by Jiang Yan, it can be said that as long as they want, they can completely produce this fine section machine.

This is good news for the country now.

"Congratulations to Jiang Gong, I thank you on behalf of all the employees of the 663 factory."

At this time, Director Zhao walked up to Jiang Yan and grabbed Jiang Yan's two hands and shook them vigorously.

"Thank you, Director Zhao, but Shen Gong and they also made a contribution, and these workers, without them, we wouldn't have been able to complete it at all."

At this time, Jiang Yan's heart was full of satisfaction, and every time he researched something new, he felt like this.

How to say it! I feel that I have contributed to the rise of the flower planter.

This kind of mood is full of feelings, the kind that nothing can bring.

The cheers of the surrounding workers have become a wonderful note at this time.

The machine maintenance and transformation was successful, and there were a lot of follow-up things, but these should be the things that should be shared by this Zhao factory director, high-intensity work to be honest, very tired and tired, and now Jiang Yan's only idea is to sleep beautifully.

After Jiang Yan handed over the full set of drawings to Director Zhao along with several of their installation records, he declined his invitation to Jiang Yan to participate in the celebration banquet.

Of course, Jiang Yan also told Director Zhao the reason why he did not participate in the celebration banquet.

Guo Jianjun, who knows how to be a person, naturally couldn't see Jiang Yan hungry, and when he escorted him back to the supply and marketing cooperative, he bought Jiang Yan a lot of things.

After returning to the hotel, Jiang Yan took a comfortable hot bath in the space, and then lay on the bed and fell asleep.
