Chapter 62 This is to ask Xiaolin
"Old Zeng, this time we use milling instead of precision casting."

"Yes, the milling process is used. This is also the main purpose of my coming here. Old man, you are an expert in the processing field. Help me look at this design drawing."

As a high-level mechanical processing expert, when looking at the design drawings, the rough drawing will appear in his mind, and then he will know a series of process steps.

Wang Tianfang looked at this design drawing seriously.

This is an integral turbine disk. The so-called integral turbine disk means that the turbine disk and the turbine blades are integrated, while the turbine disk and turbine blades of most engines are separated, connected by tenon and tenon, and combined by locking pieces.

The integral turbine disc is processed as a whole from a blank.

Both integral and split turbine disks have their own advantages.

The advantage of the split turbine disc is that it has a long service life, and the blades can be replaced and disassembled after a certain service life.

The integral turbine disk is relatively simple to process, because its process is relatively small, and the disadvantage is that its service life is short.

The life of the missile engine is generally only a few minutes, at most two or three 10 minutes, and it is disposable, regardless of the life, the design of the overall turbine disk is often used.

"Old man, everything else is fine, but the machining of the turbine blades may be a little difficult."

Zeng Zhihong said, "Yes, I also think that the difficulty in manufacturing lies in the turbine blades, because we have adopted a brand-new blade design, and the machining accuracy is also high."

The fuel of the missile is limited. With the same fuel, the designers hope that the missile will hit farther, which requires the missile engine to have better performance.

The key component that determines the performance of a missile engine is often the turbine part. The new turbine blade design is also an attempt by Zeng Zhihong and the others.

In theory, this blade design can greatly improve the performance of the turbine part, but whether it is actually the case requires design verification.

How to carry out design verification, that is to manufacture the turbine according to the design drawings, and then conduct a series of tests in the laboratory.

Zeng Zhihong said hopefully, "Mr. Wang, your factory should have the ability to manufacture this complete set of turbine disks."

Wang Tianfang said, "If it was two months ago, we didn't have this processing capability, but now we have an imported five-axis linkage CNC machine tool, the problem is probably not big."

Zeng Zhihong was about to be happy, but Wang Tianfang changed the subject and said cautiously, "You have to ask Xiao Lin about whether it can be processed or not."

Kobayashi, who is Kobayashi?
Zeng Zhihong quickly ran through all the people he knew in the Phoenix Factory in his mind, and there was no one with the surname Lin.

Wang Tianfang said, "You don't know Xiaolin. He is a young craftsman in the 406 workshop. He is not low in the field of CNC machining. Just ask him to come and ask."

It turned out to be a young craftsman!
Zeng Zhihong became curious about this young craftsman and thought in his heart, what kind of young man is this?

"Then tell him to come here quickly, or we can go to him with the blueprint."

Zeng Zhihong was a little anxious. The overall turbine disk is related to the design performance of the entire missile engine. If it cannot be processed, then the design can only be changed.

Is it possible to reduce the design precision, or to change back to the previous precision casting process?

As if feeling the old man's anxiety, Wang Tianfang smiled and said loudly, "You don't need us to go there, I'll call and just ask him to come over."

Just kidding, one is the deputy director and chief engineer of Phoenix Factory, and the other is a well-known design expert in the field of domestic aero-engines. If these two awesome characters go to find Lin Feng in person, it will scare many people.

Zeng Zhihong was also a little too impatient and didn't think about it so much, so he thought about going to find Lin Feng.

Wang Tianfang obviously knew this very well, smiled slightly, and picked up the phone on the desk.

The call went directly to the office of the director of the 406 workshop, "Director Yan, this is Wang Tianfang, please ask Xiao Lin to come to my office."

"Okay, I'll call him right away." Yan Bing, the workshop director, agreed.

The production and manufacturing site of workshop 406.

The turbine cover of the turboprop six is ​​being processed on that domestic CNC machine tool.

There are many drilling and milling processes for high-temperature alloy materials. It is very suitable for such parts to be processed on this CNC machine. Multiple processes can be combined into one process to complete.

The first part has been processed, the inspection is completely qualified, and the inspector also stamped the "First Inspection Passed" stamp, and the processing of the second part has started.

Because multiple processes are merged into one process, the efficiency is doubled, and even Wang Qiang himself can't believe it.

"Master, I have done this part before. It is drilling and milling. These processes can't be finished in a few hours. Our machine tool took less than two hours, even half of the original one. The time is not up."

Lin Feng nodded slightly, and said in his heart that the processing efficiency can actually be faster, but the cutting tool is not powerful. If there is a high-performance alloy cutting tool, the efficiency can be increased by at least one-third.

At this time, Yan Bing, the workshop director, walked over quickly, and said loudly at least ten meters away.

"Xiao Lin, Mr. Wang called you to go to his office, hurry up, he is waiting for you in the office."

what!
Mr. Wang personally called Lin Feng!

Because Yan Bing's voice was loud enough, many people nearby heard it, and immediately, they all felt a burst of envy.

Mr. Wang is looking for it himself!

Lin Feng is so awesome. Throughout the year, I rarely even meet Mr. Wang's face a few times. It can't be compared.

Lin Feng was also slightly taken aback, and immediately reacted, and replied, "Okay, I'll go there now."

After briefly explaining to Wang Qiang, Lin Feng left immediately and went to the factory building.

While walking on the road, Lin Feng was also guessing in his mind, what is the matter that Mr. Wang suddenly came looking for me.

After thinking about it for a long time, I couldn't figure it out, so I just stopped thinking about it, walked into the factory building, and arrived at the door of Wang Tianfang's office familiarly.

This floor is full of offices for the factory leaders, including the offices of the first and second leaders.

Lin Feng was at the door of an office with the words "Chief Engineer's Office" hanging on it. He took a deep breath to calm himself down as much as possible, and then he raised his hand and knocked on the door.

"come in."

Hearing the voice from the office, Lin Feng gently pushed the door and walked in, "Mr. Wang, you are looking for me."

"Xiao Lin, come over and take a look at this design drawing." Wang Tianfang waved his hand.

Lin Feng noticed that besides Wang Tianfang, there was a middle-aged man in the office, who gave Lin Feng an appreciative look.

　Everyone, please collect it!
