Chapter 1240: Eliminated goods for export to domestic sales
"this……"
Of course, the person in charge of the Aerospace Manufacturing Factory wanted to defend himself, but after a long time of long mouth, he didn't let go of his farts, and was speechless by Zhuang Jianye.
The 0.15mm air film cooling holes, and the number is as high as 1,800. This is no longer ordinary hole processing in the traditional sense, but has risen to the scope of special processing. Not only that, because of the quantity factors, it is also the top and most complex special population hole processing in special precision hole processing.
In this regard, let alone Japan, even Germany, which is the leader in mechanical equipment, cannot do this. Only a superpower like the United States, which has an absolute technological leadership in the aviation field, can have such capabilities.
So let alone the person in charge of the Aerospace Engine Manufacturing Factory in front of you can't get it out, even if you search all over Japan, you can't find such equipment. Otherwise, why would Japan stumbling in the aviation manufacturing industry? Except for the older generation of aviation designers left over from World War II in the 1960s who used the whole country to create an unsuccessful regional passenger plane, it has never even made a piece of self-produced aircraft skin over the past few decades?
It’s not that the overall industry has been invisibly suppressed, and there is no way to move forward in this direction. Of course, it’s okay to build high-end foundry factories and workers for American aviation giants, but because of this, Japan’s aviation industry has been completely limited to the local area, and there is no opportunity to touch the whole.
Just like a blind man touching an elephant, even if he does the part well, he still cannot be fully sublimated at a higher level without a sense of overall feeling.
This also brings unsurpassable limitations to Japan's mechanical processing equipment. After all, the aviation industry is often very experienced. You can't even get in touch with Japan, so how can you talk about experience?
Therefore, Japanese hole processing machine tools may be able to do a very good job of precision holes around 1mm, but they can't play with super precision holes below 0.3mm, let alone super precision holes such as air membrane holes on turbine blades of aircraft engines. Not to mention doing it, it is estimated that the Japanese have never seen them.
After all, Americans don’t just give it to the Japanese for their own work. Americans always do core components like aircraft engines, and never take action on others.
The person in charge of the Aerospace Manufacturing Factory is doing business, not really polite, and is clear about these things. As for Zhuang Jianye, who has been vigorously promoting the processing equipment produced by Tengfei Group, it doesn’t need to be said. So when the person in charge of the Aerospace Manufacturing Factory was speechless, Zhuang Jianye was not polite and shook the metal wave spring in his hand: "And this, the thickness is 2mm, the entire spring needs to be equipped with 627 process holes with a diameter of 0.1mm. If you know people from relevant Japanese companies, ask them if there is a 0.1mm drill bit?"
As soon as these words came out, the people in charge of the aerospace factory present noticed that the wave spring was also densely covered with extremely thin holes.
This is not because these people did not observe carefully, but because of the ceramic materials, they preconceived that the metal materials inside do not need to be treated too much, and the light is blocked under the wings, and a group of veteran cadres outside the fifties are all presbyopic, so it is normal not to notice for a while.
But when Zhuang Jianye reminded him, these people naturally reacted. They immediately found the reading glasses when they were not good at their eyes. Several even took out magnifying glasses and looked at the sample carefully for a while, before they could exclaim a series of awesomeness.
"It's very difficult to make a hole of 0.15mm, and the material is so thin that it can't be done by ordinary heat sources or machining."
"Yes, heat sources will cause a melting layer to appear around the material holes, which will damage the properties of the material itself; and if purely machining, such thin materials can easily cause cracks and will make the waste rate scary."
"Yeah~~Yes, 0.15mm is fine, 0.1mm is the thickness of ordinary printing paper. Whether it is heat source processing or mechanical processing, it is impossible to do it. Even the most advanced equipment on the market can't be done with our best operators, so..."
"It should be electrochemical processing. I remember Tengfei Group seemed to have developed similar equipment."
"I remember some time ago, the person in charge of the Aerospace Engineering Manufacturing Factory that fought with Zhuang Jianye imported two electrochemical processing centers from Japan..."
The surroundings were getting louder and louder, but among these noisy discussions, the processing technology of the metal core and the air film cooling holes on the wave springs that Zhuang Jianye took out was becoming clearer and clearer in front of everyone.
There is no way. Although most of the people present are leaders, they are all old birds who have been working in the aeroengine industry for decades. It may be a bit embarrassing to get them started to build aircraft engines themselves, but it is still quite reliable to let them get their hands on them.
But because of this, the person in charge of the Aerospace Engine Manufacturing Factory, who fought with Zhuang Jianye, calmed down from the panic just now. Although he didn't say anything, the smelly face showed such a relaxed attitude, as if saying, "Tengfei Group has electrochemical processing equipment, we have it too, and it's better than yours. It's purely imported from Japan, and it's the birthplace of electrochemical equipment, it's definitely world-class. How about it? No curse it!
"Xiaozhuang, we do have several brother factories that have introduced electrochemical processing equipment from Japan. The overall process is very good. As you said just now, you are willing to transfer some of the technology to brother factories, so..."
At this time, the deputy director spoke in time and picked peaches as usual. That’s fine. The key is that the expression that you should eat is to be beaten as much as you deserve.
After hearing the deputy director's words, the other aviation factory leaders stopped for a while, and then stared at Zhuang Jianye with a strange look, as if he had seen some prey, and the next moment he could pounce on him and dismantle them directly.
There is no way, the only position of these aviation and development factories is political achievements. If the things of Tengfei Group are irreplaceable, then lower your head and admit your timidity, and cooperate with each other; but if Bai Piao can afford to pay any price, of course he has to try it, otherwise he will become a fool?
So among them, it is not just the head of the Aviation Development Factory who fought with Zhuang Jianye, who is full of verbalism and business in his heart, but one person is not a good person.
Of course, it also includes Zhuang Jianye!
