    Looking at the machine-based step leader who was walking behind Zhuang Jianye, whether it was the deputy director or the person in charge of the aviation engine manufacturing plant who was very tough with Zhuang Jianye, one by one, he was no longer confused, but completely  's petrified.

    You must know that it is the world's top electrochemical equipment manufacturer, Kobayashi Chemical's machine-based stepper.

    It is not easy for the heads of domestic manufacturing companies to meet him. They are lucky to have to queue up to buy equipment. It is normal to have long queues for increased prices. Therefore, wherever the machine-based step leader goes, he looks at people with his nostrils.  , Where have you ever seen this gentleman beg someone so lowly?

    ????????????? And he¡¯s a Chinese who¡¯s constantly raising prices to the point of doubting his life?

    So much so that the people in charge of these aerospace plants have a sense of absurdity that they are living in a dream, or traveling through a parallel world. There is no way, the existing values ????and world view are really shattered, making them feel that this  The world is a little too crazy, and mice have become bridesmaids to cats.

    ¡°You guys~~~~You guys~~~~¡±

    Just when everyone was confused, the old general who was walking in front suddenly spoke, and then he looked at everyone including the deputy director with an expression as cold as a grandfather looking at the prodigal grandson with eyes full of hatred.  The people in charge of the aircraft engine plant stretched out their hands and nodded one by one, and said with great regret: "Can't you be more careful? They are all in their forties or fifties. I am a bad old man who has to bury his pornographic pictures above his head.  Is it okay to scold you a few times to wake up?"

    The people who were confused were even more at a loss when the old commander scolded him for no reason. They didn't know why the old commander suddenly got angry, so a person in charge of the aircraft engine factory who had a good relationship with the old commander took the courage to be careful.  asked: "Master, what is this"

    "What am I?"

    Before the person in charge of the inquiring aircraft engine factory could finish his words, the old commander retorted back angrily, and then pointed at Zhuang Jianye and the machine-based step leader who were walking further and further away: "The key is them, a  Are you going to hand over the world-class high-end equipment to the Japanese again? Every day, everyone values ??political achievements more than their lives. What is the result? When the opportunity comes to get political achievements, they just look like a fool.  Opportunities just passed by me and I didn¡¯t even bother to stretch out my hands. I¡¯m just old and my body really doesn¡¯t allow it anymore, so I don¡¯t need more. If it were three years ago, I would have taken off my leather shoes and slapped each other a dozen times.  If you can¡¯t wake up if you scratch your ears, you¡¯ll be beaten to death!¡±

    "Commander, please calm down, calm down" Seeing that the senior commander was really angry, another aviation development manager quickly stepped forward to comfort him. Not only that, this one also hinted to the assistant to put his  The quick-acting Jiuxin Pills were prepared. I was afraid that the boss would be in trouble if he got angry, so he said it politely: "We all know this truth. The problem is that we don't know the new technologies of Ascendas Group yetespecially the machine-based infantry."  We have never even heard of what the nb-6857 six-axis composite machining center the director is talking about. You always say that we gave it up to others, which is really an injustice to us"

    The person in charge of the aerospace engine plant expressed his grievances and sincerity. His words were both truthful and gentle. The key is that he still makes sense. Others also nodded. This is indeed the case. nb-6857 six-axis  The name of the compound machining center is very lofty, but what exactly does this thing do? No one here knows it clearly. Naturally, it is impossible to talk about understanding. Since you don't know, how can you know whether the technology applied is good or bad?

    "I am impatient"

    After listening to the explanations of others, the old master sighed and calmed down his anger a little, but he still said with sonorous words: "But you also have to understand, because the metal core and wave spring in the high-pressure turbine guide blade you just saw  The air film cooling group holes on the machine were made using the nb-6857 six-axis composite machining center."

    "Oh? So this equipment is also an electrochemical equipment?" The deputy director stepped forward and was about to continue talking, but was stared back by the old teacher: "If it is a general electrochemical equipment, I  Is it necessary to give you a chance?

    That is a composite special processing equipment that combines two different processes: electric spark and electrochemistry"

    ¡°As he spoke, the chief engineer slowly explained the basic situation of the nb-6857 six-axis composite machining center.

    It turns out that there are generally three processing techniques for film cooling holes on turbine blades of aeroengines. One is the electric spark process, the second is the laser process, and the last is the most advanced electrochemical process.

    Among them, the EDM process is the most mature and efficient; the laser energy density is the highest; and the electrochemical process has the best quality.

    However, aside from the advantages, the shortcomings of these three processes are also obvious. Due to the discharge effect of the EDM process, it is easy to form a recast layer around the hole, micro-cracks, burrs and sharp edges and other sequelae, which affect the overall structural strength of the blade, leading to??Quality decline.

    In addition to all the shortcomings of electric sparks, the biggest drawback of laser is that the energy density is too high, which is good for thick materials. If it is thin material, it can easily penetrate the outer clamp or workpiece if it is not controlled well.

    The electrochemical process is not as certain as the above two processes. It can almost process the most perfect film cooling holes at one time. However, this process has an unavoidable problem, that is, the production efficiency is too low.

    With a general electrochemical single-hole machine, it would take at least 120 hours to make a low-pressure turbine blade with more than 1,200 film cooling holes.

    If it is a two-hole machine, it will take less time, but it will still take 80 hours to complete.

    There are at least hundreds of guide blades and turbine blades for an aero engine, and each one takes 80 hours. The length of hundreds of them together can make people¡¯s scalp numb.

    This is still the quantity of one aero-engine. Mass-production aero-engines can only produce hundreds or thousands of units. The total time taken together is absolutely an astronomical figure.

    Of course, some people will say that if there is a two-hole machine, there should be a three-hole, four-hole or even five-hole machine. Wouldn¡¯t this be more efficient?

    The idea is good, but the problem is that the electrochemical equipment, except for the two-hole machine, has no way to separate the excess drilling chemical liquid injection tube.

    The reason is also very simple. The medium of electrochemical equipment is highly corrosive and toxic chemical synthesis agents. Driving such reagents requires special materials and accessories. The cost itself is very high. Being able to accurately control two injection holes is already a must.  At the limit, it is impossible to do more than three holes.

    Therefore, if you want to quickly process a batch of film cooling holes, you can only expand the scale of the electrochemical equipment and use the so-called sea of ??machine tactics to pile up a batch of film cooling holes.

    Just doing this will cost you a terrible amount of money.

    The nb-6857 six-axis composite machining center of Tengfei Group is a high-quality and efficient air film cooling hole processing equipment developed based on the contradiction between quality and efficiency that plagues aerospace film cooling hole processing.

    "nb-6857 six-axis composite machining center has both the efficiency of electric sparks and the high quality of electrochemistry" After some introduction, the old manager concluded: "So it is used in processing high-precision air film cooling holes.  The efficiency is quite high. Normally, the nb-6857 six-axis composite machining center can complete about 2,000 high-pressure turbine blade film cooling holes in less than eight hours."

    "Eight hours?" The person in charge of the aircraft engine factory who prepared the quick-acting Jiuxin Pill exclaimed in surprise when he heard this. The next moment, he left the still angry chief engineer and chased Zhuang Jianye who was about to enter the maintenance workshop.  While running, he shouted: "Mr. Zhuang, we bought your nb-6857 six-axis composite machining center. You can give me a price, no matter how much you want"
