"This one……"

Of course, the person in charge of the Hangfa Manufacturing Factory wanted to defend himself, but he kept his mouth open for a long time, and he was dumbfounded by Zhuang Jianye, who didn't let out both farts.

0.15mm film cooling holes, and the number is as many as 1,800. This is no longer ordinary hole processing in the traditional sense, but has risen to the category of special processing. Not only that, because of quantitative factors, it is also special precision hole processing. Among the top, the most complex special population hole processing.

In this respect, let alone Japan, even Germany, which is the leader in machinery and equipment, can't do it. Only the United States, which has an absolute technological leadership in the aviation field, has such capabilities.

So don’t say that the person in charge of the aviation manufacturing factory can’t get it out. Even if you search all over Japan, you can’t find such equipment. Otherwise, why should Japan stumble in the aviation manufacturing industry, except in the 1960s. The older generation of aerospace designers left over from the Second World War put together a national effort to create an unsuccessful regional airliner. For decades, even a piece of self-produced aircraft skin has not been built?

It’s not that the entire industry has been invisible suppressed, and there is no way to move forward in this direction. Of course, it’s no problem to build high-end foundries and wage earners for American aviation giants, but it is also because of this that Japan’s aviation industry has been It is completely restricted to the part, and there is no chance to touch the whole.

Just like a blind person, even if you do a good job of the part, you still can't complete the higher-level sublimation without the overall feeling.

And this also brings the limitations of Japanese machining equipment that are difficult to overcome. After all, the aviation industry is very experienced in many cases. You can't even touch the Japanese connection. How can you talk about experience?

Therefore, Japanese hole processing machine tools may be able to do well with precision holes of about 1mm, but ultra-precision holes below 0.3mm will not work, let alone the air film applied to the turbine blades of aero engines. Kong has such an ultra-precision group of holes, let alone do it, I guess the Japanese have never even seen it.

After all, what Americans do when they find Japanese OEMs are not all heartbroken and thrown to the Japanese. For core components such as aero engines, Americans have always worked on their own, and never leave it to others.

The person in charge of the Hangfa Manufacturing Plant is doing business and is not really arrogant. He has a clear understanding of these things. As for Zhuang Jianye, who has been trying his best to promote the processing equipment produced by the Ascendas Group, let alone, so see As the person in charge of the Hangfa Manufacturing Factory was speechless for a while, Zhuang Jianye was also welcome, and the metal wave spring in his handle flicked: "There is also this, with a thickness of 2mm. The entire spring needs to be equipped with 627 0.1mm diameters. Craft hole, if you know someone from a Japanese company, ask them, do you have a 0.1mm drill?"

As soon as these words came out, all the people in charge of the aviation development plant at the scene noticed that the wave spring was also densely covered with extremely fine small holes.

This is not because these people did not observe carefully, but because of the inclusion of ceramic materials, they preconceived that the internal metal materials do not need to be treated too much, and the underside of the wing already blocked the light, and a group of fifty outside. The veteran cadres of China have presbyopia again, so it is normal to not notice for a while.

But after being reminded by Zhuang Jianye, these people naturally reacted, and immediately found reading glasses if their eyes were not good. Some even took out a magnifying glass and looked at the sample carefully for a while before sending out a series of messages. Amazed.

"It's very difficult to make a 0.15mm hole, and the material is so thin that it can't be done with ordinary heat sources or mechanical processing."

"Yes, the heat source will cause a fusion layer around the material hole, which will damage the nature of the material itself; and purely mechanical processing, such a thin material will easily cause cracks, which will make the rejection rate scary."

"En~~ Yes, 0.15mm is fine. 0.1mm is the thickness of ordinary printing paper. Whether it is heat source processing or mechanical processing, it can’t be done at all. Even with the most advanced equipment on the market, it’s best for us. The operator can’t do it either, so..."

"It should be electrochemical machining. I remember Ascendas Group seems to have developed similar equipment."

"I remember some time ago, I imported two electrochemical machining centers from Japan with the person in charge of Zhuang Jianye's rigid aviation manufacturing plant..."

The surrounding discussion became more and more noisy, but among these noisy discussions, the processing technology of the metal core and the film cooling hole on the wave spring that Zhuang Jianye took out became more and more clearly presented in front of everyone.

No way, although most of the present are leaders, all of them are veterans who have been in the field of aviation for decades. It may be difficult for them to build aero engines by themselves, but let them take control. The eyes are pretty reliable.

But precisely because of this, the person in charge of the Hangfa Manufacturing Factory who was rigid with Zhuang Jianye also calmed his mind from the panic just now. Even though he didn't say anything, his stinky face showed what it was. The relaxed posture seems to be saying that your Ascendas Group has electrochemical processing equipment, we also have it, and it is better than yours, purely imported from Japan, that is the birthplace of electrochemical equipment, properly world-class, how about ? No curse!

"Xiao Zhuang, we do have several brother factories that have imported electrochemical processing equipment from Japan. The overall process is very good. As you said just now, you are willing to transfer part of the technology to brother factories, so..."

At this time, the deputy director spoke in a timely manner, picking peaches as always, that's all, the key is that the expression that will eat you up is to be more owed and owed.

The other person in charge of the aviation development factory who heard the words of the deputy director also stopped the round. UU reading www. uukanshu.com immediately stared at Zhuang Jianye with a strange gaze, as if he had seen some prey, and he could pounce on it in the next moment.

No way, the only position of the heads of these aviation development plants is their political achievements. If the Ascendas Group’s things are irreplaceable, then lower your head, recognize a counsel, and cooperate; but if you can do nothing at all costs, of course Go and try, or you will become a fool?

Therefore, among them, it is not just the head of the aviation development plant who is rigid with Zhuang Jianye who is full of ethics and business in his heart, but one is not a good bird.

Of course it also includes Zhuang Jianye!

Because of this, as soon as the long post on the rationality of "monkey picking peaches" was over when the deputy director-general was over, Zhuang Jianye replied with a smile, and immediately turned the breezy face of the deputy director-general into the bottom of the pot: "Electrochemical Machining We eliminated all the equipment in the second half of last year, and even the patented technology was sold to Kobayashi Chemical of Japan...Um...Leader, don't tell me that the few brother factories purchased were produced by Kobayashi Chemical and eliminated our export. The goods are bought back at a big price?"
