If Mellinz understands the Zu'an culture of the Chinese people, guess your mother will not hesitate to paste Zhuang Jianye's face.

Of course, even if you don't know, the mainstream sayings that start with F or S are repeated in my heart countless times, countless times.

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

That's right, he is engaged in aerospace technology, and the well-informed Merlinz is indeed very confused when he looks at the equipment in front of him.

If you say that high-end drilling equipment such as laser, plasma or electron beam is used, the most traditional mechanical tools are used inside this modern special drilling machine.

How to look at how there is a sense of déjà vu in the appearance of gold and jade, since it is a traditional mechanical hole processing equipment, you look so scientific and technological and have an egg use.

However, it is a simple traditional hole processing equipment, but it is very different from the equipment in the general processing plant, that is, the drill bit of the equipment in front of it does not cooperate with the coolant or cutting fluid as an auxiliary during the processing process.

It is important to know that high-speed drilling bits or tools in general machining will inevitably generate a lot of heat, and their high temperature will even melt most of the metal, which is why coolant or cutting fluid should be injected into such high-speed machining equipment.

But in the machine in front of me, there is not even a shadow of liquid around the high-speed running rotor, just running at high speed, under the control of industrial software, the carbon fiber composite panel on the fixture keeps drilling one after another.

After one plate is processed, the next plate immediately follows, and the special control equipment runs at high speed as always, repeatedly.

Merlinz watched quietly for a long time, and noticed that the drill bit would pause for a moment except between the two plates, and the rest of the time it was running non-stop.

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

Can we blindly accommodate the erosion of carbon fiber composites by coolant or cutting fluid, regardless of high temperatures, will we ensure that the finished product meets the expected effect?

It is important to know that the sensitivity of carbon fiber materials to temperature cannot be ignored, although there are such as steel, aluminum, copper and other metal materials are so lively, but the temperature change will still cause subtle differences in materials.

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

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

Tengfei Group doesn't seem to care about this, and still uses the drill bit commonly used in machining as the main force for carbon fiber materials, which is enough, the problem is that the quality of processing is still very good.

Just now, Merlinz looked at the microscopic imaging played to them by the inspector who was responsible for inspecting the processing quality next to him, and it can be seen from the picture that the carbon fiber material panel that has been processed in batches not only has few burrs on the edge of the opening, but also has very low roughness, and there is no subtle crack common in machining.

This surprised Merlintz, if it is electron beam, plasma, laser even if it is EDM, high-speed water cutting, Merlinz can accept, after all, these methods are the most advanced hole processing methods in the world today.

The equipment of the Tengfei Group only uses ordinary machining methods, and the processed things are not only inferior to those advanced processes, but even superior in some aspects.

Not to mention, the cost of use alone is much lower than other advanced processes, after all, human beings currently use the longest time, but also the most mature is machining, other processing technology is of course not bad, the problem is that the production and operation are essentially different from traditional machining equipment.

This is also an important reason why satellite spare parts in Europe and the United States are expensive, in addition to the scary high labor costs, abandon traditional machining, completely use expensive other processing technology, and make things that are not expensive.

But without those expensive high-tech processing methods, what is the way to make ordinary machining achieve the same effect as high-tech means such as electron beam? Could it be that God really descended to earth and turned stones into gold?

However, just when Mellinz was puzzled, and scolded Zhuang Jianye for selling the guanzi blindly, but had to lower his head to ask the reason, a long-forgotten professional term suddenly flashed in Merlintz's mind, so the words that were about to be asked immediately became "Wait~~ I seem to remember, your equipment is using ultrasonic vibration processing technology." ”

Zhuang Jianye was raising his head and preparing to ask Mellintz with his head down, he directly loaded this 13 directly to the full grid, no way, who let Mellintz not be authentic, in the "1314520 Factory History Exhibition Hall" just now, the words connotate themselves.

If you dare to threaten, you have to be mentally prepared to be pretended to be 13 and slapped in the face.

That's right, Comrade Lao Zhuang is so cautious.

I really didn't expect that the big belly on Merlintz's body was not white, in addition to the fat meat, it also contained a lot of dry goods, and I could actually see that the DL-666 in front of me, the automatic hole making machine applied ultrasonic vibration processing technology.

But what can this be, can it just be that Comrade Lao Zhuang can forgive?

"Haha~~ Mr. Mellinz is worthy of being an expert in the field of aerospace, and you can see it at a glance, yes, our DL-666 uses ultrasonic vibration processing technology, not only it. ”

Before the words fell, Zhuang Jianye led Merlinz and others into the factory quickly, and then pointed to a running three-axis CNC milling machine not far away and said: "This DL-250 three-axis CNC milling machine, and the ...... over there."

Then he pointed to a machine that was doing complex surface processing in front and continued: "DL-233 CNC EDM equipment, and DL-123 portable punching machine used by the workers in front...... Without exception, they all use ultrasonic vibration machining technology. ”

Zhuang Jianye paused as he spoke, withdrew his gaze from the huge car, and looked at Merlinz and the others who were shining with surprise: " Through the large-scale application of ultrasonic vibration processing technology, not only the machining accuracy of the old machining equipment in the past has been improved by several orders of magnitude, but also the cost of use has been greatly reduced, because of this, we Tengfei Group in the original NB series of aviation professional equipment, to create a new DL series of aerospace special equipment, we see these equipment in the workshop is the result of our group in recent years, and their goal is only one, that is, to bring down the expensive cost of satellites. ”
