Chapter 1046

After listening to Zhuang Jianye's words, Aziz was stunned for a moment, but at the next moment, he unconsciously tilted his mouth and shook his head: "Mr. Zhuang, I can admit that you Tengfei group is a leader in the global laser field, but there is a consensus in the industry. I think you should be clear that laser processing technology is not suitable for micro precision processing in the aviation field."

After a pause, the middle-aged man on Aziz's side immediately respectfully handed over a bottle of soda water with his hands. Aziz took it with indifference and drank it gracefully. Then he cleared his throat and continued: "I can't deny that in the extreme situation, using laser can produce qualified products, but this single measure has no replicability Generally speaking, it is not in line with the mode of industrial production... "

Aziz is worthy of being a senior expert who has spent most of his life in European aviation technology circle. His knowledge and experience are impeccable both in theory and practice.

Let's not say anything else, but laser processing, which is not a particular field in aviation manufacturing, is by no means a mainstream manufacturing process. Aziz can say everything, which shows that this person's attainments in aviation technology are quite good.

Aviation experts from the United Arab Emirates and Algeria, who have gradually gathered together because of Aziz's dialogue with Zhuang Jianye, also nodded their heads in agreement after hearing Aziz's words.

Let alone an outsider, a few of the air force experts who accompanied the head of the headquarters agreed with Aziz, frowning and worried.

So Aziz's statement is not only correct, but also quite correct. Even in a sense, it has become a recognized consensus in the industry.

Laser processing technology, especially precision hole processing, has incomparable advantages over other processing methods, such as simple operation, low cost and convenient efficiency.

But also has its own insurmountable shortcomings, that is, the laser wavelength is too large, the pulse is too high, resulting in the surface temperature of drilling parts is too high, easy to cause the internal thermal stress around the process hole is too large, the surface recast into more and thick, and even form fine cracks around the process hole.

The civil parts with low structural strength requirements are not much, but the aviation manufacturing field with strict requirements, let alone cracks, is that excessive internal stress may cause structural fatigue of the parts, and the life of the parts will be sharply reduced, which will threaten the flight safety of the whole machine.

When it comes to more sophisticated aeroengines, these shortcomings are even more intolerable.

Because of this, laser processing technology is generally used for cutting or welding in aviation manufacturing industry. Of course, recently, there is an additive manufacturing.

But no matter which one, it is far from hole processing, especially micro precision hole processing.

In the past, Tengfei group did not use laser to process the film cooling holes of turbine blades. Instead, it used a manufacturing technology called electrochemical drilling technology. Its advantage is that it can complete the processing of film cooling holes at one time without any other process.

The problem is that the electrochemical drilling technology is the production technology of Tengfei group five years ago. Now that the Soviet Union has disintegrated and the world pattern has changed, Tengfei group must cross the next century with the old yellow calendar, and can't keep pace with the times?

"Well, Mr. Aziz, and other experts, let's move to our WC-8 honeycomb combustion chamber production workshop to see if our nb-6600dl ultra precision laser drilling machine can realize what you call industrial mass production."

After Aziz popularized the knowledge that laser processing is not suitable for precision hole processing recognized by the world aviation industry with elegant Royal intention, Zhuang Jianye did not refute, but said a proposal with a smile, and then walked to the door on the other side first.

"Your Highness Abdullah, your highness Mahmoud, why don't we go with you?" Seeing Zhuang Jianye leave, the head of the headquarters immediately sent an invitation to the two real speakers.

How could Abdullah and Mahmoud refuse the real big man, the head of the headquarters? They immediately nodded, chatted with the head of the headquarters and left slowly with Zhuang Jianye.

Seeing the two princes leave, Aziz and others have to go with them even if they don't want to. What's more, they are also curious about what kind of equipment is the nb-6600dl ultra precision laser drilling machine in Zhuang Jianye's mouth. Can it really break the consensus of the aviation industry for many years?

One by one, they quickly followed. After five or six minutes' walk, they finally came to a factory built of reinforced concrete. After several procedures, such as changing, dedusting, disinfecting and sterilizing, they entered the workshop with dust-proof clothes and goggles. From a distance, they looked like the ones carved in a mold.

However, Aziz and others not only did not feel trouble, but after stepping into the workshop, they were shocked by the two extremely sophisticated equipment in front of them.

In front of the meeting, the equipment with nb-6600dl on the facade is about 5 meters long, 3 meters wide and 2.5 meters high. On the left side is the processing area, where there are five WC-8 honeycomb combustion chamber flame tubes in a row, on which the flexible laser is facing one of the flame tubes, and the high-energy laser is used to accurately make process holes.However, this is not surprising for Aziz and others. After all, they have seen a lot of laser drilling equipment in Europe and the United States, and even some of their own processing machines have laser processing equipment. What makes them really incredible is the observation window on the right side of the device, which is used to observe the operation of the internal mechanism of the device.

I really don't know. It's enough to scare Aziz and other people in the industry. Every time the equipment runs, the light source inside the equipment will be refracted, reflected and finally injected into the laser to form high-energy pulse.

"This set of institutions is It's It's Lithography machine.... "

A well-informed Algerian expert twisted his eyebrows and pondered for a moment. He always thought where this set of institutions had been. After thinking for a long time, he finally opened his eyes and cried out in surprise.

"This gentleman is really knowledgeable. He even knows the mechanism of the lithography machine. Our nb-6600dl can't compare with the real lithography machine. It can do abnormal level existence below 193 nm. At present, our nb-6600dl can only compress the laser to 355 nm, which is still half way behind."

Before the middle-aged expert's words were heard, Zhuang Jianye came over with a stack of documents and handed the documents to Aziz: "Mr. Aziz, this is the random sampling test result of the micro precision process holes of the flame tube that have just been processed. There are 1182 holes in total, and there is no internal thermal stress, recast layer or crack. Of course, if you If you don't believe it, there is our laboratory, which has the most sophisticated testing equipment in the world. You can choose from these products or test them together. "

Zhuang Jianye seems very magnanimous, but Aziz did not listen to the words behind Zhuang Jianye, because his whole brain has been shocked by the previous sentence of Zhuang Jianye. He didn't react until Zhuang Jianye finished saying it. He asked naively: "Mr. Zhuang, how much can your nb-6600dl compress the laser wavelength? 355 nm? "
