Kunlun Seiko's speed shocked everyone. In less than six minutes, a set of marine propellers was milled. Such efficiency was crazy.

After all, it takes more than 40 minutes to use a traditional five-axis milling machine to manufacture the same set of propellers. Kunlun Seiko's manufacturing efficiency is about seven times that of traditional machine tools.

The Western melon-eating crowd was extremely upset and sent barrages to complain.

Huaxia Manufacturing is already amazingly efficient, and now with such an efficient fully automatic machine tool, I am afraid that it will farewell the whole world in terms of cost.

Gao Yuan looked at some barrage, and then said with a smile: "Kunlun Seiko can achieve such high efficiency. In addition to high-speed drivers, the more important thing is material technology. Our carbon nanotube condensate is not only strong, but also resistant to high temperatures. If it were replaced with ordinary metal and cut at such a fast speed, it would have been red and transformed because of the high temperature."

"Of course, speed is just one aspect, and the key is to look at accuracy. Submarines, rockets, and supersonic aircraft. The more advanced the mechanical structure, the higher the accuracy requirements."

"Now please look at the big screen. After laser and magnetic resonance joint detection, the error of this set of marine propellers is as follows."

Swish ~

The big screen behind it suddenly flashed, and then a lot of data appeared.

"Average error, 1.26 microns!?"

"It's actually only more than one micron? Wouldn't that mean that the surface of the propeller is smoother than a mirror?"

"I always feel like Kunlun Seiko hasn't actually done all her strength."

"I also feel this way. If the speed is reduced and fine grinding is fine, the error should be easily achieved below one micron."

"Nanoscale machine tools!? Do you know what you are talking about?"

"So what about nano? Although it is more difficult, this is Kunlun Group, a legendary company that is good at creating miracles!"

The error result excited everyone. Audiences who have learned mechanical skills even pointed out that one micron is probably not the limit of Kunlun precision craftsmanship. Judging from the drastic performance of the machine tool just now, it is not like doing fine work, and a set of propellers can be milled out casually.

Assuming that Kunlun Precision has given enough time and slowly carving, this machine tool will definitely be able to surpass microns and enter the world of nano-level precision.

For this reason, the audience cheered and looked forward to the next aircraft blade manufacturing.

"Well, the results are pretty good." Gao Yuan looked at the big screen, and he didn't care at all. He nodded slightly and said, "The error is more than one micron, which is in line with our expectations. After all, it is high-speed processing, and the stability of the machine is slightly poor. And after all, it is enough for propellers to achieve one micron accuracy. Even if the propeller used for nuclear submarines, the error is more than five microns."

"Now our engineering team is doing the final debugging for Kunlun Precision, after all, it is a challenge to the world's most accurate parts. Aeroengine blades not only need to be adjusted, but the carbon nanocondensates used later will also be more expensive and more refined."

"The materials to be milled have been installed, so our engineers are only wearing white dustproof clothing because they are afraid of dust pollution and reducing processing accuracy."

The engineers of Kunlun Group seemed very cautious and repeatedly checked and proofread the machine. It took more than twenty minutes before making an OK gesture to the plateau to signal the machine to complete the inspection.

Huh ~

Gao Yuan let out a long sigh and patted the shoulder of the manipulator engineer next to him.

The control engineer understood and pressed the start button. The machine made a very faint buzzing sound, and the robotic arm pulled out the No. 3 milling cutter from the tool holder.

"This process will be relatively long, so we can take advantage of this time to talk about the issue of aircraft engines." Gao Yuan smiled, as if he was preparing to enter the traditional class time.

"The full name of the aeroengine blade is called the aircraft engine high-pressure turbine rotor blade. This type of blade requires complex internal cooling airways. In the past, it was modeled first and then poured with a special ceramic."

"In other words, the aerospace blades are not milled, but poured. The pouring process is extremely troublesome, involving not only metal materials science, but also mechanical technology and chemical coating technology."

"Every time you pour, countless layers of coatings are required. The coating technology directly determines the quality of the blades. At present, all over the world, except for Russia, still using maids to coat them manually, other countries have already used robotic arms."

Sure enough, the plateau started classes, but unlike in the past, he was more like introducing interesting little knowledge in the manufacturing process of aeroengine blades.

Through popular science on the plateau, the audience gradually understood why aerospace engineering is so difficult to build. In order to prevent overheating, the blades are usually coated with ceramics, but ceramics are a little brittle. During high-speed operation, even if the ceramic coating falls off at zero points and one grams, it is fatal to the engine.

So scientists thought of zirconia, and used an electron gun to shoot out an electron beam to establish a magnetic field. The electron beam is guided by the magnetic field and accurately hit the zirconia substrate. The substrate bombarded by the electron beam will instantly turn into a gaseous state. The gaseous zirconia is then guided by the magnetic field and adhered to the blade surface to grow rapidly.

In the end, zirconia will grow into small sticks with a diameter of 1 micron and a length of 50 microns, densely covered with the surface of the leaves. There can be subtle relative movement between the small sticks, but the whole piece will not peel off. At this point, the problem of the blade's heat-resistant coating has been solved.

Except for a few aviation fans, most of the melon-eating people didn’t know this. After hearing the plateau, they went crazy on the spot! It turned out that just the blade coating was so difficult!

No wonder Aero Engine often takes more than ten years or even decades from design to production. It is worthy of being the brightest jewel in the crown of the industry, and its technical level is too high.

Gao Yuan said: "But luckily, the casting method faces various difficulties in manufacturing aerospace blades, which does not exist for us, because we started with materials. Carbon nanotube polymers can overcome high temperatures and can still fly even without thermal conductivity holes. Their hardness and toughness are more than titanium alloys..."

After hearing this, the audience posted barrage in the audience.

"Uh, what Boss Gao said so easily, it seems a bit hateful."

"Absolutely, if I were an engineer from Boeing or Lockheed Mart, I would probably be so angry that I would spit out old blood."

"It's so bullying. Western aviation-engine blades have to go through so many processes. They need to pull the front-mounted technology tree. Boss Gao is so simple and crude! Just go to the machine tool to mill!"

Before we knew it, more than twenty minutes had passed, and five sets of marine propellers were able to mill, but the aircraft engine blades had just been set, the speed of the robotic arm was slowed down, and they were extremely patient, and they were constantly polishing over and over again.

The laser detector seems to have never stopped since the beginning, and the red light wires are constantly scanning the blades to check for any minor changes.

Waiting time is inevitable to make people anxious. The plateau continues to teach classes and teaches some small knowledge about aeroengine manufacturing. Time passes by minute by minute, and I don’t feel bored.

In a blink of an eye, more than an hour had passed. Even though the plateau was eloquent and spoke lotus, the audience didn't want to hear it at this moment. They were all staring at the exquisite work of art in the workshop.

It is round and flawless, with a glimmer of light on the surface, as crystal clear as black pearls, countless blades are stacked layer by layer, elegant curves and sharp curves, perfectly fitting aerodynamics, and from any angle, it contains an ultimate beauty.
