Kunlun Seiko's speed shocked everyone, and it took less than six minutes to mill a set of marine propellers, which is insanely efficient.

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

The people who eat melons in the West are extremely annoyed and have sent barrages to complain.

Huaxia manufacturing is already amazingly efficient, and now there is such an efficient fully automatic machine tool, I am afraid that in terms of cost, it will leave the world far behind.

Gao Yuan looked at some barrage, and then said with a smile: "Kunlun Seiko can achieve such a high efficiency, in addition to high-speed drives, in fact, the main thing is material technology, our carbon nanotube condensate is not only strong, but also able to resist high temperatures, if it is replaced with ordinary metal, cutting at such a fast speed, I am afraid that it will have long been reddened and deformed because of the high temperature." ”

"Of course, speed is only one of the aspects, the key depends on accuracy, submarines, rockets, supersonic vehicles, the more sophisticated the mechanical structure, the higher the requirements for precision."

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

Swish~

The big screen behind him suddenly flashed, and a lot of data appeared immediately.

"Average error, 1.26 microns!?"

"It's just over a micron? Doesn't that mean that the surface of the propeller is smoother than a mirror? ”

"I always feel that Kunlun Seiko is actually not doing its best."

"I also feel the same way, if you reduce the speed and grind finely, the error should be easily less than one micron."

"Nanoscale machine tools!? Do you know what you're talking about? ”

"What about nanometers? Although it is more difficult, this is Kunlun Group after all, a legendary enterprise that is good at creating miracles! ”

The error results made everyone excited, and the audience who had learned machinery pointed out that one micron may not be the limit of Kunlun Seiko, looking at the machine tool just now, it doesn't look like doing fine work at all, and a set of propellers is milled out casually.

Assuming that Kunlun Seiko is given enough time to carve slowly, this machine tool will definitely be able to surpass the micron and enter the world of nanometer precision.

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

"Well, the results are not bad." Gao Yuan looked at the big screen, didn't care about it, and said with a slight bow: "The error is more than one micron, in line with our expectations, after all, it is high-speed processing, and the stability of the machine is slightly poor, and in the final analysis, the propeller is completely enough to have an accuracy of one micron, even if it is a propeller for nuclear submarines, the error is more than five microns." ”

"Now our engineering team is doing the final debugging for Kunlun Seiko, after all, it is a challenge to the world's highest precision component, the aviation development blade, not only the machine to be adjusted, but also the carbon nano condensate to be used later, but also more expensive and finer."

"The milling material has been installed, and our engineers only wear white dustproof clothing, because they are afraid that dust pollution will reduce the machining accuracy."

The engineers of Kunlun Group were very cautious, repeatedly checked and proofread the machine, and it took more than 20 minutes before making an OK gesture to the plateau to signal that the machine had been inspected.

Call~

Takahara let out a sigh of relief and patted the shoulder of the control engineer next to him.

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

"It's going to be a long process, so we can take advantage of this time to talk about aero engines." Takahara was smiling, as if he was getting ready for the traditional school day.

"The full name of the aviation engine blade is called the aero engine high-pressure turbine rotor blade, which requires a complex internal cooling airway, which used to be modeled first and then poured with a special ceramic."

"That is to say, the blades are not milled, but poured, and the pouring process is extremely troublesome, not only involving metal materials, but also mechanical technology and chemical coating technology."

"Every time you pour, you need countless layers of coating, the level of coating technology, directly determines the quality of the blade, at present, all over the world, except for Russia is still coated by hand, the rest of the countries have used robotic arms."

Sure enough, Gao Yuan started to take classes, but unlike before, he was more like an introduction to interesting trivia about the manufacturing process of aviation blades.

Through the popular science of the plateau, the audience gradually understood why it is so difficult to make this thing, in order to prevent overheating, the blades are usually coated with ceramics, but the ceramic thing is a little brittle, and in high-speed operation, even if the 0.01 gram of ceramic coating falls off, it is fatal to the engine.

So scientists thought of zirconia, using an electron gun to shoot an electron beam, establish a magnetic field, guide the electron beam by the magnetic field, and accurately hit the zirconia substrate, the substrate bombarded by the electron beam will instantly become gaseous, and the gaseous zirconia will be guided by the magnetic field and attach to the surface of the leaf to grow rapidly.

Eventually, the 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 blade, and the small sticks can move slightly relative to each other, but will not peel off the whole piece, so that the problem of heat-resistant coating of the blade is solved.

Except for a few aviation fans, most of the people who eat melons know this, they went crazy on the spot after listening to Gao Yuan! It turned out that it was just a blade coating, and it was so difficult!

It is no wonder that it often takes more than ten years or even decades from design to production, which is worthy of being the most shining pearl in the industrial crown, and the technical level is too high.

Gao Yuan said: "But fortunately, there are all kinds of difficulties in manufacturing aviation blades by casting method, which does not exist for us, because we started with materials, carbon nanotube polymers can overcome high temperatures, even if there are no thermal conductive holes, they can still fly, and the hardness and toughness exceed that of titanium alloys..."

Listening to this, the audience barrage was sent off the stage.

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

"Definitely, if I were an engineer from Boeing or Loma, I would probably spurt out a mouthful of old blood."

"It's too bullying, the West makes aviation hair blades, it has to go through so many processes, and it needs to be full of pre-technology trees, and Boss Gao is good, simple and rude! Milling directly on the machine! ”

Unconsciously, more than 20 minutes have passed, and the marine propeller can be milled out of five sets, but the aviation blades have just been finalized, and the speed of the mechanical arm has slowed down, and it is very patient, and it has been polished over and over again.

The laser detector never seemed to stop from the beginning, with the red filament constantly scanning the blade to check for any slightest changes.

The waiting time is inevitably anxious, Gao Yuan continued to take classes, talked about some small knowledge of aviation manufacturing, and the time passed minute by minute, but he did not feel bored.

In a blink of an eye, more than an hour has passed, Rao is Gao Yuan can speak well, spit lotus flowers, and the audience doesn't want to listen to it at the moment, they are all staring at the exquisite artwork in the workshop.

It is rounded and flawless, with a shimmering surface that shines like a black pearl, and countless layers of blades, elegant curves, sharp curves, perfect aerodynamics, and a supreme beauty from any angle.

It took one hour, seventeen minutes and five seconds to complete the aviation blades!
