    "this¡­¡­"

    Of course, the person in charge of the aviation engine manufacturing plant still wanted to defend himself, but after being so big-mouthed for a long time, he didn¡¯t even fart. Zhuang Jianye was so stunned that he was speechless.

    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 category of special processing. Not only that, because of the quantity factor, it is also special precision hole processing.  Among them, the most advanced and complex special group hole processing.

    In this regard, not to mention Japan, even Germany, which is the leader in mechanical equipment, cannot do it. Only superpowers like the United States, which has absolute technological leadership in the aviation field, have such capabilities.

    So don¡¯t say that the person in charge of the aviation engine manufacturing plant in front of you can¡¯t get it. Even if you search all over Japan, you can¡¯t find such equipment. Otherwise, why would Japan stumble in the aviation manufacturing industry?  The older generation of aviation designers left over from World War II worked hard across the country to create an unsuccessful regional airliner, but in decades they haven't even built a single piece of self-produced aircraft skin?

    It¡¯s not that the entire industry has been suppressed invisibly, there is no way to move forward in this direction. Of course, it is no problem to work as a high-end foundry and wage earner for the American aviation giant, but because of this, Japan¡¯s aviation industry has been  Completely limited to the local area, without even a chance to touch the whole.

    It¡¯s like a blind man touching an elephant. No matter how well you do the parts, without a sense of the whole, you still can¡¯t achieve a higher level of sublimation.

    And this also brings insurmountable limitations to Japanese mechanical processing equipment. After all, the aviation industry is often very demanding of experience. You, a small Japanese, can't even come into contact with it, so how can you talk about experience?

    Therefore, Japanese hole processing machine tools may be able to do very well with precision holes of about 1mm, but they cannot make ultra-precision holes below 0.3mm, let alone the air film used on aeroengine turbine blades.  It is estimated that the Japanese have never even seen such an ultra-precise group of holes, let alone made them.

    ¡°After all, when Americans hire Japanese OEMs, they don¡¯t leave all their heart and soul to the Japanese. For core components like aero engines, Americans have always done it alone and never relied on others.

    The person in charge of the aircraft manufacturing plant was in business, and he was not really a doctrinaire. He was very knowledgeable about these matters. Not to mention Zhuang Jianye, who had been vigorously promoting the processing equipment produced by Ascendas Group, so he saw  Seeing that the person in charge of the aircraft manufacturing plant was speechless for a moment, Zhuang Jianye was not polite and shook the metal wave spring in his hand: "There is also this, with a thickness of 2mm. The entire spring requires 627 0.1mm diameter ones.  For craft holes, if you know people from relevant Japanese companies, leader, ask them if they have 0.1mm drill bits?"

    As soon as these words came out, the heads of the aircraft engine plant present noticed that it turned out that the wave spring was also densely covered with extremely fine holes.

    This is not because these people are not observing carefully, but because of the inclusion of ceramic materials, they preconceptionally believe that the internal metal materials do not need too much processing. In addition, the underwings block the light. A group of people fifty years away  The veteran cadres all have presbyopia, so it is normal for them to be unaware for a moment.

    But after being reminded by Zhuang Jianye, these people naturally reacted and immediately found their reading glasses if they had bad eyesight. Some even took out their magnifying glasses and looked at the samples carefully for a while, and then issued a series of  Marvel.

    "It is very difficult to make a 0.15mm hole, and the material is so thin that it cannot be made by ordinary heat sources or mechanical processing."

    "Yes, the heat source will cause a deposited layer to appear around the holes in the material, which will damage the properties of the material itself; and for pure mechanical processing, such a thin material can easily cause cracks, which will increase the scrap rate to a terrifying level."

    "Well~~ That's right, 0.15mm is enough. 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 with the most advanced equipment on the market, it is best to cooperate with us  Operators can¡¯t do it either, so¡­¡±

    "It should be electrochemical processing. I remember that Ascendas Group has developed similar equipment."

    "I remember that some time ago, the person in charge of the aircraft manufacturing plant who was tough with Zhuang Jianye imported two electrochemical machining centers from Japan"

    The surrounding discussions are becoming more and more noisy. However, among these noisy discussions, the processing technology of the metal core and the air film cooling holes on the wave spring that Zhuang Jianye took out is becoming more and more clear to everyone.

    There is no way, although most of the people present are leaders, but all of them are veterans who have been in the field of aviation for decades. It may be a bit difficult for them to start building aero engines by themselves, but let them master it.The eyesight is quite reliable.

    But precisely because of this, the person in charge of the aviation engine manufacturing plant who was stern with Zhuang Jianye also calmed down from the panic just now. Although he didn't say anything more, his stinky face showed that it was like this.  The relaxed gesture seems to be saying, your Ascendas Group has electrochemical processing equipment, we also have it, and it is better than yours. It is purely imported from Japan. That is the birthplace of electrochemical equipment, and it is world-class. How about it?  ?  No more chanting!

    "Xiaozhuang, we do have several brother factories that have introduced electrochemical processing equipment from Japan. The overall technology is very good. You just said that you are willing to transfer part of the technology to the brother factories, so"

    At this time, the deputy director spoke at the right time, picking peaches as usual, that's all. The key is the look on your face that will tell you whether you deserve a beating or not.

    After hearing the words of the deputy director, the other heads of the aircraft engine plant also stopped in unison, and immediately stared at Zhuang Jianye with a strange look, as if they saw some prey and could pounce on it in the next moment.  Cut into pieces.

    There is no way. The only position of the heads of these aircraft engine plants is political achievements. If the things of Ascendas Group are irreplaceable, then they should bow their heads and admit that they are cowards. It is time to cooperate; but if they can do it at any cost, of course  You have to try it, otherwise you will become a fool?

    So among this group of people, not only was the person in charge of the aircraft engine factory who was tough with Zhuang Jianye full of doctrines but thinking about business, there was also one who was not a good bird at all.

    Of course, including Zhuang Jianye!

    Because of this, as soon as the deputy director's long speech on the rationality of "monkey picking peaches" ended, Zhuang Jianye replied with a smile, which immediately made the deputy director's cheerful face turn black: "Electrochemical processing.  We eliminated all the equipment in the second half of last year, and even sold the patented technology to Japan's Kobayashi Chemical Um Leader, don't tell me, several brother factories purchased products produced by Kobayashi Chemical and eliminated the ones we exported.  Did you spend a lot of money to buy the goods again?"
