Chapter 47
"What about Xiao Lin, why didn't you see him?"

Wang Tianfang asked again, he looked around the meeting room just now, there were more than [-] people, he didn't seem to see Lin Feng's figure, not even in the corner.

Many people are envious!
Mr. Wang actually asked Lin Feng himself, this is not common!
The deputy factory directors hold meetings in the factory office building. Generally, the secretaries of the factory office are responsible for organizing the meeting, such as arranging and arranging the meeting room, and notifying the participants of the meeting.

Xiao Wang, the secretary of the factory office, was at a loss.

There is a big question mark in my heart, who is Kobayashi?

In his mind, he quickly went through the middle-level leaders in the factory, as well as senior engineers and professor-level senior engineers.

I was even more puzzled. Among so many people, there was no one with the surname Lin, and there was only one surnamed Lin among the retired experts. But he was 70 or [-] years old, and it was impossible for Deputy Factory Director Wang to call him "Little Lin".

Who is this "Little Lin"?
Wang Tianfang glanced at Xiao Wang, and waved his hand impatiently, "Forget about this meeting, and Xiao Lin must be notified to attend the next meeting."

Why forget it this time?

In fact, Wang Tianfang didn't think that Lin Feng had any good suggestions on how to repair the three turbine casings. He could provide a way to find out the faulty parts of the three combustion chamber casings, which is already very remarkable.

In his opinion, Lin Feng is just a new technician who has only worked for three years.

Forget it.

Wang Tianfang didn't continue to ask Lin Feng why he didn't attend the meeting, which made Xiao Wang, the secretary who organized the meeting, quietly breathe a sigh of relief.

Xiao Wang thought in his heart, the first thing to do after the meeting is to quietly ask, who is the "Xiao Lin" that Deputy Director Wang is talking about.

Wang Tianfang said, "The faulty parts of the three combustion chamber casings have been found out, and they are all in the same position. Although the overhaul manual does not have a repair plan for this part, these three casings must be repaired, and they must be repaired as soon as possible."

"Next, let's discuss how to repair these three receivers. Everyone can speak, and if there are good methods and plans, tell them."

As soon as Wang Tianfang finished speaking, a professor-level senior engineer at the meeting said, "The repair of this part can only be done by welding, but we all know that welding may cause deformation of the welded part, and this position is too close to the turbine bearing. "

The turbine bearing is the most important bearing in the whole engine, and the center line determined by it and the compressor bearing is also the center axis of the whole engine.

Turbine bearings are so important, and the precision of the bearing holes is very high. This is one of the tricky places for everyone. Once welding deformation occurs, the problem will be serious.

It didn't take long for the meeting room to become a little dull. Everyone knows that it is extremely difficult to repair it by welding.

No way, Wang Tianfang had no choice but to come up with a plan himself, and asked, "How many turboprop six-combustion chamber casings do we have scrapped?"

The director of the central warehouse immediately replied, "There are four more, two of which were dismantled from the engine after the engine reached the end of its life, and the other two were scrapped due to size deviation during the manufacturing process."

There are four in total.

I hope the quantity is enough, Wang Tianfang said, "Since we are not sure about welding, let's use the scrapped combustion chamber casing to do the test first. I think that as long as the welding parameters are proper, the deformation can be controlled."

For the time being, we decided to test the welding parameters first, and then formally use the welding method to repair the three combustion chamber casings after it is safe.

It’s just that it takes time. In addition, the number of casings for the four combustion chambers is a little too small. There may be four scrapped casings that have been used up. As a result, reasonable welding parameters have not been tested yet.

All in all, the stakes are high right now.

406 Workshop.

Because no one had informed him to attend the meeting, and Lin Feng didn't know that as soon as he went to work today, Chief Engineer Wang organized a meeting in the factory building to discuss the repair of the three turboprop six-combustion chamber casings.

Lin Feng first wrote two or three thousand words, and then went to the production site to have a look.

Whether it is the imported five-axis CNC machine tool or the domestic CNC machine tool, they are all processing parts.

The four apprentices were divided into two groups. Hu Xiaoxiao and Ma Xiaoli operated imported CNC machine tools, while Wang Qiang and Song Liu operated domestically produced CNC machine tools.

They (they) are now able to operate the CNC airport, and Lin Feng will go to see the processing situation in person from time to time, and sometimes he will give guidance.

After returning from the production and manufacturing site in the workshop, Lin Feng originally wanted to go back to his own separate office to continue coding, but after thinking about it, he went to the big office in the process technology room.

In this big office, Lin Feng's position is still reserved, and he often comes over to sit.

In the workplace, the relationship with colleagues must still be good. If he stays alone in that private office all day, Lin Feng is a little worried that he will gradually become estranged from his colleagues.

Lin Feng would sit in this big office basically every day, and even chat with his colleagues.

"Brother Lin, you're here."

Yang Wenjie greeted Lin Feng first, he was sitting next to him, and the relationship between the two was usually relatively good.

The point is that Yang Wenjie is now pursuing Ma Xiaoli, so he is more polite and enthusiastic towards Lin Feng. Although it is not to the extent of licking, it is not much worse.

"Come and read a book for a while."

Lin Feng replied, and sat down in his seat. There were still many professional books on the big table, all of which were borrowed from the factory archives.

Sometimes, instead of going to the archives to borrow books by yourself, give the library card to Hu Xiaoxiao or Ma Xiaoli and tell them what books to borrow, and they will do the errands for them.

"Lin Gong, when you have time to teach us CNC programming, how about it?"

"Xiao Lin, I will read the technical manual of the imported five-axis in a few days."

"Lin Feng, I really envy you. You have your own separate office and a computer."

The colleagues were enthusiastic and greeted Lin Feng, and Lin Feng responded one by one, without any coldness, but also with the same enthusiasm.

However, there was a voice that made Lin Feng slightly uncomfortable.

"Lin Feng, I heard that you went to the test stand with Director Jiang yesterday. How about it? Gain some knowledge. This is the first time you saw an engine test run."

That was Ji Fenghua, in his 40s, an old technician and Maggie's mentor.

Although he is in his 40s and has worked for more than 20 years, his relationship with his colleagues is not very good. For example, there are less than 20 people in the crafts and technology room, and at least three or four of them are at odds with Ji Fenghua.

Ji Fenghua is a person with mediocre talents, but he has a good temper and a petty temper. He is a typical person with a small belly.

His apprentice Ma Ji was beaten up in front of Lin Feng several times, and Ji Fenghua also began to taunt Lin Feng, as long as there was a chance, he would definitely not let it go.

For such a person, Lin Feng really doesn't want to talk to him, it is of course best to keep a distance.

The tree wants to be still, but the wind does not stop.

Lin Feng didn't want to get involved with Ji Fenghua, but Ji Fenghua did not intend to let him go.
