Chapter 769

If merlinz knew the Zuan culture of Chinese people, your mother would not hesitate to look at Zhuang Jianye.

Of course, even if you don't know, the mainstream saying of the poor f or s in Europe and the United States also circulates in your heart and roars for countless times, countless times.

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

Yes, merlinz, who is engaged in aerospace technology and has a lot of knowledge, is really confused when he looks at the equipment in front of him.

If it is high-end drilling equipment such as laser, plasma or electron beam, this special drilling equipment with modern appearance is equipped with the most traditional mechanical tools.

How do you think there's a kind of gold and jade? The sense of vision is that since it's a traditional mechanical hole processing equipment, you have a sense of science and technology in your appearance.

It can be said that it is a simple traditional hole processing equipment, but it is very different from the general processing plant equipment, that is, the drill bit of this equipment has no matching coolant or cutting fluid as auxiliary in the processing process.

We should know that in general machining, high-speed drill or cutting tool will inevitably produce a lot of heat, and its high temperature will even melt most of the metal, which is why we need to inject coolant or cutting fluid into such high-speed machining equipment.

But in front of this device, there is no liquid shadow around the high-speed rotating head, so it is running at high speed, and under the control of industrial software, it is drilling the carbon fiber composite panel on the fixture one after another.

After one piece of plate is processed, another piece of plate immediately follows, and the special control equipment runs at high speed as usual.

Merlinz looked at it quietly for a long time, and found that the drill would stop for a while, except for the alternation between the two plates.

As a professional, he can understand all kinds of taboos in the processing of carbon fiber composites. For example, due to the different chemical properties of epoxy resin, some special carbon fiber composites will react with coolant or cutting fluid to destroy the properties of materials.

Can we just indulge the erosion of carbon fiber composites by coolant or cutting fluid, regardless of high temperature, and ensure that the finished products meet the expected effect?

We should know that the sensitivity of carbon fiber materials to temperature can not be ignored, although there are steel, aluminum, copper and other metal materials so active, but the change of temperature will still cause subtle differences in materials.

Although these differences are not obvious, on the most meticulous space equipment, even a few microns of error may lead to the complete scrapping of a valuable space spacecraft.

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

It seems that Tengfei group doesn't care about this. It still uses the drill commonly used in mechanical processing as the main force for manufacturing carbon fiber materials. That's all. The problem is that the processing quality is still very good.

Just a moment ago, merlinz saw the microscopic image played by the inspector in charge of inspecting the processing quality. From the picture, it can be seen that the carbon fiber material panel processed in batches not only has few burrs at the edge of the opening, but also has very low roughness. As for the micro cracks commonly seen in machining, there is no one.

This makes merlinz surprised. If it is made by electron beam, plasma, laser, even EDM, high-speed water cutting, merlinz can accept it. After all, these methods are the most advanced hole machining methods in the world.

However, this equipment of Tengfei group only uses ordinary machining methods, and the processed products are not inferior to those advanced technologies, or even superior in some aspects.

Apart from other things, the cost of using it alone is much lower than other advanced technologies. After all, machining is the longest and most mature technology currently used by human beings. Of course, other processing technologies are also good. The problem is that there is a fundamental difference between manufacturing and operation and traditional machining equipment.

This is also an important reason why satellite parts in Europe and the United States are expensive. In addition to the frightening high labor costs, it is difficult to make things that are not expensive by abandoning traditional machining and completely using other expensive processing technologies.

But without those expensive high-tech processing methods, what method can make ordinary machining achieve the same effect as electron beam and other high-tech means? Is it hard for God to come down to earth and turn stone into gold?

However, when merlinz couldn't figure out why, and he had to bow his head to ask why, he suddenly flashed a professional term that had been forgotten for a long time in his mind, and the words about to ask immediately turned into: "wait a minute ~ ~ I seem to remember that your equipment is using ultrasonic vibration processing technology."

Zhuang Jianye is looking up and ready for merlinz to ask. He directly put this 13 in the full grid. There's no way. Who let merlinz express himself in the "1314520 factory history museum" just now.

If you dare to threaten, you have to be prepared to be pretended to be 13.Yes, comrade Lao Zhuang is so careful.

I really didn't expect that merlinz's belly was not white. In addition to fat meat, it also contained a lot of dry goods. I could see that the dl-666 automatic drilling machine in front of me applied ultrasonic vibration processing technology.

But what can we do? Can we make Comrade Lao Zhuang forgive us? Dream about it.

"Ha ha ~ ~ Mr. merlinz is worthy of being an expert in the field of aerospace. You can see it at a glance. Yes, our dl-666 uses ultrasonic vibration processing technology, not only it."

Before the words are heard, Zhuang Jianye leads merlinz and others to enter the factory quickly, then points to a running three-axis CNC milling machine not far away and says: "this dl-250 three-axis CNC milling machine, and the one over there..."

Then he pointed to the front of a complex surface processing equipment and continued: "dl-233 CNC EDM equipment, and dl-123 portable drilling machine used by workers in front They all use ultrasonic vibration processing technology without exception. "

With these words, Zhuang Jianye pauses and looks back from such a big car year to the surprised merlinz and others: "through the large-scale application of ultrasonic vibration processing technology, not only the processing accuracy of the old-fashioned mechanical processing equipment has been improved by several orders of magnitude, but also the use cost has been greatly reduced. Because of this, our Tengfei group is in the original factory Besides NB series aviation professional equipment, we have created a batch of new DL series aerospace special equipment. What you see in the workshop are the achievements of our group in recent years, and their only goal is to reduce the expensive satellite cost. "
