    ¡°If Merlinz understood the Zaun culture of the Chinese people, I guess your mother would definitely look at Zhuang Jianye without hesitation.

    Of course, even if you don¡¯t know it, the poor mainstream idioms starting with f or s in Europe and the United States are still repeated in your heart countless times, countless times.

    Guess, if I can guess it, I can ask you!

    Yes, Merlinz, who is engaged in aerospace technology and is well-informed, was really confused when he looked at the equipment in front of him.

    Speaking of high-end drilling equipment such as laser, plasma or electron beam, the modern-looking special drilling equipment in front of you uses the most traditional mechanical tools inside.

    ??????????????????????????????? There is a sense of d¨¦j¨¤ vu with the appearance of gold and jade but the inside is crumbs. Since it is a traditional mechanical hole processing equipment, it is of no use to make the appearance so technological.

    It can be said that it is a simple traditional hole processing equipment, but it is very different from the equipment in general processing plants. That is, the drill bit of this equipment does not have coolant or cutting fluid as an auxiliary during the processing process.  .

    It should be known that in general machining, high-speed drill bits or cutting tools inevitably generate a large amount of heat, and the temperature is so high that it will even melt most metals. This is why it is necessary to inject coolant or cut into such high-speed machining equipment.  liquid reasons.

    But in the equipment in front of me, there is not even a trace of liquid around the high-speed rotating head. It is running at such a high speed, and under the control of industrial software, it moves against the carbon fiber composite panel on the fixture one after another.  Keep drilling.

    ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? After the processing of one plate, another plate is immediately followed, and the special control equipment runs at the same high speed as before, and the cycle begins again and again.

    Merlinz looked at it quietly for a while, and found that except for the alternating between two plates, the drill bit would stop for a moment, and it would keep running at other times.

    As an industry insider, he can understand the various taboos in the processing of carbon fiber composite materials. For example, some specially made carbon fiber composite materials will react chemically with coolant or cutting fluid due to the different chemical properties of the connected epoxy resin.  Destroy material properties.

    Can we just tolerate the erosion of carbon fiber composite materials by coolant or cutting fluid, and ignore the high temperature? Will we ensure that the finished product meets the expected effect?

    It should be noted that the sensitivity of carbon fiber materials to temperature cannot be ignored. Although metal materials such as steel, aluminum, and copper are as active, changes in temperature will still cause subtle differences in materials.

    Although these differences are not obvious, in extremely meticulous aerospace equipment, an error of even a few tenths of a micron may lead to the complete scrapping of a valuable space vehicle.

    Because of this, in developed countries in the United States and Europe, many space equipment companies have replaced traditional mechanical processing with more advanced high-energy equipment such as electron beams and lasers.

    ??Tengfei Group doesn¡¯t seem to care about this. It still uses drill bits commonly used in mechanical processing as the main air control force of carbon fiber materials. That¡¯s it. The problem is that the quality of the processing is still very good.

    Just now Merlinz watched the microscopic image played to them by the inspector responsible for inspecting the processing quality. From the picture, it can be seen that the carbon fiber material panels processed in batches not only have very few burrs at the edges of the openings, but also have roughness.  It is so low that there are no tiny cracks that are common in machining.

    This surprised Merlinz. If it is made by electron beam, plasma, laser, or even electric spark or high-speed water cutting, Merlinz can accept it. After all, these methods are the most advanced hole processing in the world today.  means.

    But this equipment of Tengfei Group only uses ordinary mechanical processing methods, and the processed products are not only no worse than those with advanced processes, but are even better in some aspects.

    Not to mention other things, the cost of use alone is much lower than other advanced processes. After all, the longest and most mature one used by humans is mechanical processing. Of course, other processing processes are also good. The problem is that the manufacturing and operation are different from those of other advanced processes.  There are essential differences between traditional mechanical processing equipment.

    This is also an important reason why satellite spare parts in Europe and the United States are expensive. In addition to the horrifyingly high labor costs, it is difficult to abandon traditional mechanical processing and completely use other expensive processing techniques to make things that are not expensive.

    Without those expensive high-tech processing methods, is there any way to make ordinary mechanical processing achieve the same effect as high-tech methods such as electron beams?  Could it be that God really came down to earth and turned stones into gold?

    However, just when Merlinz was puzzled and scolded Zhuang Jianye for being blind, but he had to lower his head and ask why, a long-forgotten professional term suddenly flashed in Merlinz's mind, and he was about to  ?When the question came to my lips, it immediately turned into: "Wait~~ I seem to have remembered that your equipment uses ultrasonic vibration processing technology."

    Zhuang Jianye was raising his head and chest, preparing for Merlinz to lower his head and ask. He directly loaded the 13 to the full grid. He had no choice but to make Merlinz unreasonable. In the words of "1314520 Factory History Exhibition Hall" just now,  Connotate yourself.

    If you dare to threaten, you must be mentally prepared to be slapped in the face by pretending to be 13.

    Yes, Comrade Lao and Zhuang are so narrow-minded.

    I really didn¡¯t expect that the big belly on Merlinz¡¯s body was not in vain. In addition to fat, it also contained a lot of dry goods. I can actually see that the DL-666 in front of me is a fully automatic hole-making machine that uses ultrasonic vibration processing.  technology.

    But so what, is it just because you can make Comrade Lao and Zhuang forgive?  Dream on.

    "Haha~~Mr. Merlinz is indeed an expert in the aerospace field. You can tell at a glance that yes, our DL-666 uses ultrasonic vibration processing technology, not just it."

    Before he finished speaking, Zhuang Jianye led Merlinz and others into the factory quickly, and then pointed to a three-axis CNC milling machine that was running not far away and said: "This DL-250 three-axis CNC milling machine, and over there  The one"

    Then he pointed to a piece of equipment that was doing complex curved surface processing in front and continued: "The DL-233 CNC EDM equipment, and the DL-123 portable drilling machine used by the workers in front they are all used without exception.  Ultrasonic vibration processing technology.¡±

    Zhuang Jianye paused for a moment, then looked away from the huge car and looked at Merlinz and others with surprised eyes: "Through the large-scale application of ultrasonic vibration processing technology, not only the old-fashioned mechanical processing equipment of the past has been transformed into  The machining accuracy has been improved by several orders of magnitude, and the use cost has been greatly reduced. Because of this, our Ascendas Group has created a batch of brand new dl series aerospace special equipment in addition to the original nb series aerospace professional equipment. Everyone in the workshop  The equipment you see is the result of our group in recent years, and they have only one goal, which is to reduce the cost of expensive satellites."
