Start with the aviation industry

Chapter 347 This Is My Master

"What are you doing in a daze, quickly take the parts down!"

Probably because he disliked the operator's slow speed, Jiang Haitao urged him personally, not just him, everyone wanted to see if the parts would be deformed after they were taken off, and if the size would pass.

"Yes, yes, quickly take the parts off!"

"I hope that the measurement of the parts under the machine tool is also qualified!"

"I really want to see the measurement results!"

"..."

In the eyes of everyone, the operator finally took the part off the extra bed and placed it on the work table next to the machine tool.

"Quickly measure those sizes just now!"

"Forget it, I'll do it myself!"

Feeling that the operator's reaction was a bit slow, Jiang Haitao took the measuring tool to measure it himself.

First size, pass!

Second size, pass!

The third size is still qualified!

……

I measured all the dimensions just now in one breath, and a competent technician next to me also recorded the actual value of each dimension.

OMG!

All qualified! ! !

Jianghai City held the white paper that recorded the actual value of the size, and said loudly, "It's a success, it's a success, every size is qualified, and the results of the measurement on the machine and the measurement under the machine are exactly the same!"

"Let me see!"

"Really, there is basically no change!"

"All qualified, and basically still poor!"

"..."

All of a sudden, the place was extremely lively, and some people even became excited, such a difficult processing problem that had troubled them for so long was actually solved!
"Boss Lin is amazing!"

"Yeah, it's amazing!"

"After Mr. Lin changed the NC program in this way, not only the processing efficiency doubled, but also the problem of processing deformation disappeared!"

"I am so impressed!"

"..."

These words drifted into his ears, and Lin Feng felt happy for a while. It seemed that the problem was basically solved.

Wang Tianfang held Lin Feng's hand tightly, and said gratefully, "Boss Lin, thank you, thank you so much, you helped us solve a big problem!"

Lin Feng was humble for a while, and then said, "For the sake of safety, I suggest to process another one, and like this one, measure the main dimensions on and off the machine tool."

"Okay, Mr. Lin is right." Wang Tianfang fully agreed with this point, and waved his hand, "Continue to process!"

Lin Feng suggested again, "Wait a few more hours, in the afternoon, measure the processed parts again to see if there is still deformation."

The chances of this are small, but that doesn't mean it's impossible.

When processing the compressor roulette before, it was obviously a qualified part. After half a day, or after a night, it was found that the deformation appeared again, and the originally qualified part was unqualified again!

Wuyou said loudly, "Have you heard that? Do everything according to what President Lin said!"

Jiang Haitao nodded quickly, "Okay, we must do what Mr. Lin said."

Others also nodded, and Lin Feng convinced everyone again. Of course, it was Lin Feng who said how to do it, and everyone did it.

Jiang Haitao said even more loudly, "What are you still doing, start processing the second part immediately!"

The operator only reacted, and then loaded the second part on the machine tool, aligned the part, calibrated the tool and so on.

Lin Feng even took a special look at the wear and tear of the knives. He felt that there was no problem, so he nodded slightly.

The turning performance of titanium alloy is very good, and the wear on the tool during the turning process is very small, but the grinding process is different. The grinding performance of titanium alloy is very poor, and it will not be able to grind for half a day.

Why can't it be ground for a long time? It is very easy to produce surface hardening during grinding.

Turning is different!
If the tool is sharp and the turning amount is greater than 0.2, surface hardening will generally not occur.

Knowing this in his heart, Lin Feng took a look at the wear of the tool. It can be seen that the wear of the tool is very slight, and it is still relatively sharp. There is no problem in continuing the turning process.

It didn't take long for the second part to start machining!
Twenty minutes later, the machine tool stopped. This time without Jiang Haitao's urging, the operator immediately opened the safety door of the machine tool, and then took the air gun to blow off the milky white coolant on the surface of the parts.

In everyone's eyes, the operator is holding a measuring tool and ready to start measuring the size of the part on the machine tool.

"What do you think will happen this time, will you still pass the test!"

"It shouldn't be a problem, Mr. Lin is here!"

"I have confidence in Mr. Lin!"

"..."

Amidst the hot discussion between you and me, those dimensions were measured on the machine tool, and the actual measured values ​​were recorded on white paper.

"All sizes are still qualified!"

"It seems that this time is very promising. It is estimated that it will be qualified to measure under the machine tool later!"

"I was suddenly a little excited. I have never had a record of passing the process twice in a row!"

"..."

All dimensions were measured on the machine tool, and the operator looked at Jiang Haitao without further action.

Jiang Haitao said a little angrily, "What are you doing in a daze, take the part out of the machine tool, measure the dimensions just now, and operate in the same way as the first part."

"Okay, I get it now."

The operator grunted, and started to loosen the clamp plate with a wrench, and took the part down and placed it on the work table next to the machine tool.

Jiang Haitao said, "Let me do it, your speed is too slow."

So, Jiang Haitao began to measure those dimensions himself, and a supervisor next to him recorded the actual measurement value of each dimension.

Quiet down here!

Everyone watched the measurement of each size. When these measurements were completed, the scene became lively with a "boom".

"It's so awesome, as expected of Mr. Lin!"

"Surprisingly, every size is still qualified!"

"Two pieces in a row are qualified, a record!"

"..."

The scene was extremely lively, in stark contrast to the quietness just now. Everyone looked at Lin Feng completely differently, full of admiration.

At this moment, Lin Feng is the idol of everyone in Workshop 406!
Feeling everyone's stares, Lin Feng also felt a slight sense of accomplishment in his heart. The very difficult technical problems for Phoenix Factory were basically solved by himself.

For the sake of safety, it is necessary to verify again, Lin Feng said, "Process one more piece. After the processing is completed, measure the dimensions on the machine tool and under the machine tool, and compare the measured values ​​to see if there is any change."

Wang Tianfang fully agreed, and ordered loudly, "Do as Boss Lin said, and make another one!"

Jiang Haitao said loudly, "What are you still doing, continue to process the third piece!"

The operator wiped down the jigs on the machine tool and loaded the third part, and a few minutes later, the machining of the third part began.

Some people watched the processing of parts, and some people chatted happily.

"If the third piece is also qualified, then this problem that bothers us will be completely solved!"

"I don't think it's a big problem!"

"I also have confidence in Mr. Lin, and the third one will definitely pass!"

"..."

In less than 10 minutes, the third part was finished. After measuring it on the machine tool, those dimensions were still qualified.

The parts were removed from the machine tool and measured again, these dimensions are still qualified!
"The third one is also qualified!"

"Yes, no matter whether it is measured on the machine tool or under the machine tool, there is almost no change in the dimensions!"

"It seems that this problem has been solved, and there is no need to worry about parts being scrapped after processing!"

"..."

Lin Feng looked at the tool after the third part was processed, and felt that it would not be a big problem to process another part, so he suggested to continue processing.

The fourth piece of processing is completed, and the parts are still qualified!

At this time, the technicians, administrators, and even the workers who were watching around cheered uncontrollably from the bottom of their hearts.

Lin Feng took a special look at the condition of the data tool on the machine tool, and found that it was a bit worn out, so he said, "The alloy blade needs to be replaced with a new one, and we can't continue processing!"

why!

Many people are puzzled! ! !
An older, more experienced worker said, "Boss Lin, the turning of titanium alloys has very little wear on the turning tool, and there is no problem in machining seven or eight parts with one blade."

Lin Feng took the opportunity to popularize science for everyone.

"Everyone, after the tool is worn to a certain extent, it will no longer be sharp. You must use a sharper blade during processing. Therefore, in order to prevent surface hardening, this alloy blade that has processed four parts needs to be replaced. .”

That's it!

Many technicians have raised their postures!
The original turning alloy blade must be kept sharp, otherwise it is prone to surface hardening.

Wang Tianfang waved his hand and said, "Do as Mr. Lin said, and this point must be written into the process regulations, strictly specifying the number of parts processed by each alloy blade."

Several technicians in charge nodded quickly.

It's just that someone said, "Originally, a single alloy blade can process at least seven or eight parts, but now it only processes four parts. Isn't it a bit wasteful?"

Alloy blades are not cheap, each piece costs tens of dollars, and ordinary workers have to work hard for several days to earn these dozens of dollars.

"Yeah, it's a waste!"

"Oh, there is no way. In order to ensure that the parts are processed qualified, this is the only way to do it. If you waste it, just waste it."

"A compressor roulette costs thousands of dollars, but alloy blades worth tens of dollars are nothing!"

"..."

Seeing so many people caring about alloy blades, Lin Feng smiled slightly and said loudly, "It won't be wasted, they can still be used, after the alloy blades of our Leihuo Technology Industrial Group are finished finishing, they will not be discarded, It can also be used for dry semi-finishing, or for roughing."

Oh yes!

We can do the same!
Many people's glasses lit up!
"As expected of Mr. Lin, this suggestion is good, we will no longer worry about the waste of alloy blades."

The fourth part has been processed, and all dimensions are qualified. The thorny problem that plagued Phoenix Factory has been solved, and the time has already reached eleven o'clock.

Wang Tianfang was in a relaxed mood, raised his hand to check the time, and then ordered, "Continue to operate as just now, Haitao, and report to me after everything is processed."

Jiang Haitao quickly said, "Okay, no problem."

He is also in a good mood now, and he no longer has to worry about processing and scrapping parts.

Before leaving, Lin Feng added, "In the afternoon, or tomorrow, measure the dimensions of these parts after processing, mainly to see if there is any deformation."

"Okay, we will measure again and make a record of the actual measured value." Jiang Haitao replied.

The problem was solved, and Lin Feng left workshop 406 accompanied by Wang Tianxin. Immediately, the scene burst into warm applause.

"Mr. Lin, thank you!"

"Boss Lin, walk slowly, you have come to our workshop 406 often!"

"..."

Many people clapped vigorously and yelled like this loudly. They were full of gratitude to Lin Feng from the bottom of their hearts, and even a little bit reluctant to leave Lin Feng.

Amid the warm applause, the two walked out of the 406 workshop together, Wang Tian was very relieved, "Mr. Lin, this problem that troubled us has finally been solved."

Lin Feng said, "There should be no problem."

Wang Tianfang said, "Let's go, let's go out for dinner, and I have some things to ask."

Lin Feng readily agreed, "Okay, then let's go and have a drink or two."

The two went to Fenghuang Hotel, which is the own hotel of Fenghuang Factory.

When Wang Tianfang, the top leader, came, of course the hotel took it very seriously, arranged the best private room, served him with good food and wine.

The two ate and chatted.

"Brother, I really shouldn't have let you go. If you were still in our Phoenix factory, then there would be no such series of processing problems."

Lin Feng smiled, "Out of the Phoenix Factory, the world is bigger, otherwise there would be no Leihuo Technology Industrial Group."

After chatting for a while, Wang Tianfang said, "When you are free, how about talking to our technicians about machining, CNC programming, etc."

Lin Feng said, "Phoenix Factory has hidden dragons and crouching tigers. There are a lot of talented people. If I give lectures to everyone, it's not like a classmate."

Wang Tianfang said, "You are too modest. Don't mention our Phoenix factory. Looking at the whole country, who has a higher level of professional technology than you. Anyway, I don't think so."

This evaluation is relatively high, and it also shows that Lin Feng's position in Wang Tian's heart is very high.

"Mr. Lin, take the finishing turning of the compressor wheel just now as an example. Although all the parts have been processed and the problem has been solved, there are not many technicians who really understand the principle. You have to explain it to everyone. Just do it."

The relationship between the two is good, and the friendship is good. Since Wang Tianfang has already spoken, it is not easy to refuse, Lin Feng said, "Then let's do it in the afternoon, how about 03:30 in the afternoon."

Why 03:30 instead of 02 o'clock, or 30:03, of course Lin Feng has his own plans and plans. After eating, he plans to go back, take a look at his wife and children, and take a nap And so on, it is just right to arrive at Phoenix Factory at 30:[-] in the afternoon.

Seeing that Lin Feng agreed, Wang Tianfang was very happy. As for what time in the afternoon he didn't care, he took out his mobile phone and made a call in front of Lin Feng, ordering to go down, notify in place, and arrange the afternoon training.

The two chatted while eating and drinking, not only about the situation of the Phoenix Factory, but also about the situation of the Leihuo Technology Industrial Group.

For example, Wang Tianfang said with admiration, "Your stealth strategic bomber is about to start the final assembly of the first prototype. This speed is simply beyond the reach of others."

It has only been a little over a year since the design started last year, and the assembly of the first prototype has begun. Even those giants in the world's aviation industry do not have such a speed.

Lin Feng is also very satisfied with this speed, and the speed of the progress is beyond his expectations. "The full assembly of the first prototype will start in two months at most, and we will strive to complete the first flight before the National Day."

"Mr. Wang, if you are interested in the first flight of this plane, how about taking some time to come and have a look?"

This was a polite invitation to Wang Tianfang, and of course Wang Tianfang happily agreed, "That would be the best, this is the most advanced stealth strategic bomber in the world, even if you don't tell me, I still want to take a look."

After eating a meal for nearly an hour, they were full with wine and food, and the two waved goodbye. Lin Feng did not go to the company, but returned to his villa in the middle of the mountain.

When Hu Xiaoxiao saw Lin Feng coming back, she was a little surprised, "Brother Feng, why did you come back at noon?"

Lin Feng said, "Boss Wang has something to do with me. He has been staying at the Phoenix Factory this morning, and he will go to give lectures to the technicians of the Phoenix Factory at 03:30 in the afternoon."

Looking around the hall, he didn't see his son's shadow, Lin Feng asked, "Son, have you gone outside?"

Hu Xiaoxiao said, "Just fell asleep, Aunt Zhang took him to sleep."

"Aunt Zhang" is an experienced childcare wife, with her helping to take care of the children, Hu Xiaoxiao is much more relaxed.

The son was already asleep, Lin Feng suggested, "wife, let's go to bed together."

Hu Xiaoxiao smiled and gave him a blank look. The two had been married for a few years, so how could they not know that Lin Feng's little thoughts were probably more than just sleeping.

Seen through by his wife, Lin Feng smiled, picked up Hu Xiaoxiao and went upstairs.

Workshop 406, technology room.

It is not long after work in the afternoon, and the whole technology room is full of excitement. Everyone is talking about the processing of the compressor roulette in the morning.

"A total of six pieces were processed in the morning, all of which were qualified!"

"I remember that in the morning, I usually processed about two pieces, and they might all be scrapped. Once Mr. Lin makes a move, it's really different!"

"Of course, that's my master!"

"It's also my master, okay?"

Several technicians argued, saying that Lin Feng was their master.

Seeing this situation, an older technician said, "Cai Zhenjiang, Mr. Lin is not your master, right? I remember that you have nothing to do with him."

"That's right, that's right, Xiao Cai, don't come to join in the fun. Mr. Lin is not your master. Your master is not Mr. Lin's apprentice at all."

"Why isn't it my master?" Cai Zhenjiang quit. "My master who is intern at the production site is Wang Qiang, and Wang Qiang is Mr. Lin's real apprentice, and I am Mr. Lin's real disciple."

You bullshit!
This works too!

Anyone who has worked in the 406 workshop for a few years knows that Wang Qiang is really Lin Feng's apprentice. Back then, Lin Feng taught a total of four people to operate the imported CNC five-axis machine, and Wang Qiang was one of them.
