"Where are you going? no, no!" Feng Tianyou got up to find the bicycle key, "You wait here, just send someone to the shipyard with me." ”

Feng Tianyou didn't need to ride his own 28 wheeled car, Lao Chu definitely couldn't let him go by himself, the father and son got into the military vehicle and arrived at the shipyard in five minutes.

There are only a few people left guarding the shipyard now, an old man who can't walk fast and can't move the doorman came to open the door, and after the group entered, Lao Chu looked at the dilapidated small shipyard and was stunned: "It's here?"

Their parts have particularly high requirements for processing technology, requiring 10,000 tons of stamping machine stamping and forming, under this pressure, the tiny gaps inside the metal can almost completely disappear, resist deformation under high pressure and high temperature, and then carry out fine processing on this basis, and its processing accuracy is also extremely high.

If it is processed in the traditional way, the 10,000-ton press is at least more than ten meters high, and the 16-axis machine tool used in the secondary processing process is the size of three basketball courts.

Can such a big machine fit here?

"Yes, when I came back, Uncle Ming sponsored me a second-generation machine, which was in the warehouse. Feng Tianyou said, "I looked at your technical indicators, the second-generation aircraft is enough, and the first-generation aircraft is not needed." ”

Generally speaking, they call the 3D printer in the Lazy God Laboratory that has been strengthened by various kinds as the first generation machine, and the 3D printer made by the 3D printer is the second-generation machine, and it is also the highest-end 3D printer that can be used on a large scale by Lazy God Technology.

"Come and help me move the materials. Feng Tianyou ran to the warehouse and turned on the machine.

This second-generation machine is specially manufactured for Feng Tianyou, and it is aimed at the manufacture of shipyard parts, so the size is quite large, and the maximum length and width can be one meter each. The two-metre-tall parts are manufactured using kinetic metallization optimized for metalworking, i.e. accelerating the metal particles above Mach 6 and liquefiing them together with the speed and energy of impact. Under constant impact. It is possible to produce ultra-dense metal structures, and stamping is actually a principle.

The drawings provided by Lao Chu are an arm-long, slightly arcanut peculiar shaft, the required working temperature is between 220 degrees and 500 degrees, the material used is titanium aluminum alloy, and the titanium aluminum ultra-fine dust used is packed in several large boxes, and several soldiers ran to help move the materials.

Lao Chu and the others stayed outside for more than ten minutes, and they were all a little shivering from the cold. Said to Feng Dad: "This thing is not easy to process, let's find a place to rest for a while......"

An expert with gray hair who followed Lao Chu was a little uneasy, and said, "I have to go in and have a look." ”

Before he finished speaking, he saw two soldiers carefully holding something out.

Under the halogen lamp in the courtyard, the parts reflected the light like a mirror. The eyes of the experts around Lao Chu were straight, and they pounced at once.

The parts processed by titanium alloy are still very hot. Both soldiers were wearing gloves, but the expert didn't wear them. was so hot that he screamed, but even so, he was reluctant to let go and touch it.

The peculiar shaft body with microstrip bending, slender and shiny, in the eyes of experts. She's the sexiest stunner in the world.

In fact, this kind of precision processing, it is no longer possible to feel the difference by hand, the processing accuracy of the second generation machine is 10nm, that is, the thickness of a bacterium. Even if it's Superman, you can't tell the difference.

But the expert in aviation machinery couldn't help but touch it, and he was particularly obsessed with it.

"It's ...... "Lao Chu was completely shocked, is this processing aviation precision parts, or is he kneading plasticine? Even if he is kneading plasticine, it is not so fast!

In fact, they always thought that Feng Tianyou was still preparing inside, who would have thought that it had been processed?

"Wind experts say it's No. 1 and there are six more being processed. A soldier said cautiously.

"What six? Isn't it enough to process one? Is there anything wrong with this?" the expert, who was obsessed with the wonderful curve of the shaft, was taken aback and hurriedly asked. Then he quickly took out the surface roughness checker to check, and the test result was perfect, two orders of magnitude higher than the required index, and the expert's hands trembled.

Wait, if the surface is so perfect, why make something else?

Is there a structural defect in the material inside?

"No, the wind expert said that although the parts they process can achieve accuracy and strength, the stress will still be released, after the stress is released, the entire processing workpiece will have a slight deformation of about 1 micron, which may lead to increased wear and tear, so he according to the stress release, process out seven parts with slight size differences, and replace the parts about once every three months, you can ignore the stress ......" These young soldiers were not illiterate big-headed soldiers, they were all technical officers, but when they spoke, they all looked drunk, questioning their own words as they spoke.

It's a fantasy!

No, we have to go back and have a look!

As soon as they finished speaking, several of them turned around and ran towards the warehouse: "Let's go get one!"

"Wait, you guys......" The others chased after them.

A machine, about three meters high and two meters wide, sits in a gloomy warehouse, with a circular column in the center of the machine and a simple workbench next to it. Feng Tianyou was sitting in front of the console playing with his mobile phone, and when he saw them coming in, Feng Tianyou smiled and said, "What, you want to see the processing process?"

"Is this okay?, isn't this very good?" said Lao Chu.

"No, no!" Feng Tianyou stood up enthusiastically, everyone asked him to visit the aircraft carrier, where did he have any complaints? Besides, there is nothing to keep secret about this processing process.

He stood up, operated a few times, and said, "You'd better wear sunglasses, well, it's very dazzling......"

One side of the column's shell opens, revealing the vitreous inside.

The crowd saw that inside the pillar, there was a stick-like object, which was only the thickness of a finger, and it was constantly spinning.

And on the stick, countless points of light are constantly shining, as if countless fireworks exploded in the night sky at the same time, or the stars in the entire night sky suddenly began to explode at the same time.

This beautiful scenery like the explosion of a galaxy has attracted countless people who have never known it. It turns out that the process of machining a part can be so beautiful.

Feng Tianyou helped them explain the principle of kinetic energy metallization, and then said: "When each metal particle hits the body, the kinetic energy suddenly turns into potential energy, melting the metal particle into a liquid, and at the same time, a part of the energy is released as visible light. So we can see the sparkling light, the yellow-green is aluminum, the white is titanium, the red is carbon, and this time sulfur...... The powder you provide is not very pure!"

Lao Chu glared at the expert, and the expert was embarrassed.

The spectrum of titanium is very long, and it emits a dazzling white light, which is still very dazzling after looking at it for a long time, and Feng Dad touched an electric welding mask from the side. In a blink of an eye, Lao Chu was still squinting and watching, and he also handed him one, and the two of them were like participating in the palace masquerade ball, holding the mask and watching it with relish.

Others are not treated so well, squinting for a while, tears flowed, and the retina was full of light spots, so quickly don't turn your head.

Under the continuous light. The central shaft is thickening at a visible rate, but it takes only about five minutes. The shaft body already has its initial shape.

At this time, the speed began to slow down, and the points of light were no longer flashing all over the sky, but concentrated in a few places.

"The next thing you have to do is close the cover. Feng Tianyou explained, "In fact, the biggest difficulty in finishing lies in the observation accuracy, and the subsequent processing accuracy. The wavelength of visible light has far exceeded that of X-rays is required to detect it, and because of the radioactive nature of X-rays, the housing needs to be closed. ”

Using X-ray 360-degree irradiation to machine a workpiece, it is not enough to detect which position to be. It will be compensated with ultra-fine dust.

In fact, modern finishing does not mean that the "hard accuracy" of finishing equipment must be achieved, but through high-precision measurement, and then compensated and corrected to achieve the corresponding accuracy.

In this process, the algorithm and program are the most important.

This is the difference between high-precision processing and outdoor 3D printing used by Heqing, architectural printing does not need such high precision, as long as it is printed, it is not a matter of a few microns or even a few millimeters, the diameter of the particles used is larger, the printing speed is much faster, and there is no need to detect it with X-rays.

After a few minutes, the print is complete and cooled, and a robotic arm takes the printed workpiece out and places it on a stand next to it.

Seven workpieces, it took about an hour to process, Feng Tianyou was a little embarrassed, scratched his head and said: "The particle particles you provide are too fine, and there are many workpieces, if there are a little coarse particles, the processing speed of the internal body will be much faster, sorry, I have been waiting for a long time." ”

Machining the inside with coarse grains and correcting the outside with fine grains allows for much faster printing speeds.

But everyone else was completely stunned, and even Dad Feng was speechless for a long time.

Hearing Feng Tianyou's apology, Lao Chu subconsciously said: "We originally just wanted to create a ......"

The reason why so many ultra-fine dust materials are brought is because this kind of workpiece has a yield rate, and once the processing is broken, it must be replaced.

"Huh?" Feng Tianyou suddenly knew that he was making a joke, scratched his head, and said with wide eyes: "What should ......I do then?" I don't know, sorry...... Wasted your materials...... Alas, why didn't you say it earlier!"

Lao Chu didn't want to say anything, he held Feng Tianyou's hand and shook it desperately, what a simple and honest comrade!

The aviation expert looked down at the seven axes lined up and looked exactly the same, and said incoherently: "Oh my God...... How is this possible, it took us more than a month to produce a workpiece last time!"

"Times have changed,. Hearing what the expert said, Feng Tianyou smiled and quoted a famous quote from the game, then changed his serious expression and said to Lao Chu: "Comrade Chief, it's time to talk about the reward......

"Huh?" Lao Chu suddenly became nervous, no wonder seven are processed at a time, the conspiracy is here! Is this a forced buying and selling?

This kind of shaft body, the processing cost is super high, if there are seven shafts, he can only hide from creditors everywhere during the Spring Festival this year.

Don't you buy it? Fools don't buy it!

"Multi-...... How much?" asked Lao Chu.

"Ten days!" Feng Tianyou grinned and looked at Lao Chu, seeing that Lao Chu's expression was not very good, "No...... Otherwise, seven days would be fine, but there are two of us!"

"Huh?" Lao Chu was stunned. (To be continued.) )
