Lazy God Possession

"Where to fly? No, no!" Feng Tianyou got up and looked for the bicycle key. "You wait here, just send someone to the shipyard with me."

Feng Tianyou did n’t have to ride his 28-wheeler. Lao Chu certainly could n’t let him go. The father and son got on the military vehicle and arrived at the shipyard in five minutes.

There are only a few people left at the shipyard. An old fast-moving janitor came to open the door. After entering, Lao Chu looked at the dilapidated boat factory, and he froze, "Here it is? "

This part requires particularly high processing technology, which requires a 10,000-ton punch press to form. Under this pressure, the tiny gaps in the metal can almost completely disappear, and the deformation under high pressure and high temperature can be resisted, and then based on this The precision of machining is extremely high.

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

Can you fit such a big machine here?

"Yeah, when I came back, Uncle Ming sponsored a second-generation machine, which was in the warehouse." Feng Tianyou said, "I looked at your technical indicators, the second-generation machine is enough, not used. The first generation. "

Generally speaking, they call the 3D printer in the Lazy God Lab with various enhancements as the first generation machine, and the 3D printer made with that 3d printer is the second generation machine, which is also the current Lazy God technology. The most high-end 3d printer for mass use.

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

This second-generation machine is specially made for Feng Tianyou, and it is aimed at the manufacture of shipyard parts, so the size is very large, and the maximum length can be one meter each. Two-meter-high parts are manufactured using kinetic energy metallization optimized for metal processing. That is, the metal particles are accelerated above Mach 6 and liquefied by the speed and energy of the impact. Glued together. Under continuous impact, ultra-dense metal structures can be produced, and stamping is actually a principle.

The drawings provided by Lao Chu are a peculiar shaft with a long arm and a slight arc. The required working temperature is between 220 degrees and 500 degrees. The material used is titanium aluminum alloy, and the titanium aluminum superfine dust is used. A few big boxes. Several soldiers ran to help move the materials.

Several people in Lao Chu stayed outside for more than ten minutes, and they all shivered a little, and said to Feng Dad, "It's not easy to process this thing. Let's find a place to rest for a while ..."

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

Before the words were over, I saw the two soldiers carefully holding out something.

Under the halogen lamp in the yard, the part looks like a mirror and reflects the light. The eyes of the experts around Lao Chu were straight, and they all flew up.

Titanium machined parts are still hot. Both soldiers were wearing gloves. The expert was not wearing them and was howling. But even so, he didn't want to let go and touch it.

Weird curved shaft with slender, slim and bright, in the eyes of experts, she is the sexiest stunner in the world.

As a matter of fact, it is no longer possible to feel the difference in processing with this precision. The processing accuracy of the second-generation machine is 10nm. That's the thickness of a bacterium, even a superman. Can't feel the difference.

But the aeronautical machinery expert still couldn't help but feel fascinated.

"This is ... finished?" Lao Chu was completely shocked. Is this machining aviation precision parts, or is it pinching plasticine? Even pinching plasticine is not so fast!

In fact, they always thought that Feng Tianyou was still preparing inside. Who thought it was finished?

"Wind experts say it's No. 1 and six more are being processed." A soldier carefully warned.

"What six? Isn't it enough to process one? Is there anything incomplete about this?" The expert obsessed with the beautiful curve of the shaft was surprised and asked quickly. Then he quickly took out the surface roughness tester to check, and the test result was perfect, which was two orders of magnitude higher than the required index, making the experts' hands tremble.

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

Is there a structural defect in the material?

"No, wind experts say that although the parts they process can achieve accuracy and strength, the stress will still be released. After the stress is released, the entire processed workpiece will be slightly deformed about 1 micron, which may cause increased wear. Therefore, according to the stress release situation, he processed seven parts with small size differences and replaced the parts about three months to ignore the stress ... "These young soldiers are not ignorant giants, they are all The technical officer, but when he was speaking, he looked drunk and questioned his words.

This is nothing but heaven and earth!

No, you have to go back and take a look!

As soon as the words were finished, several of them turned back to the warehouse and said, "Let's get the next!"

"Wait, you ..." The others chased in together.

A machine that is about three meters high and two meters wide is placed in a dark warehouse. In the center of the machine is a circular column with a simple operating table next to it. Feng Tianyou was sitting in front of the console and playing with his mobile phone. When they saw them coming in, Feng Tianyou laughed and said, "Why, do you want to watch the process?"

"Can you? Isn't this good?" Old Chu said.

"No, no!" Feng Tianyou stood up enthusiastically, and he was asked to visit the aircraft carrier. Where can he complain? Besides, there is nothing to keep secret during this process.

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

One side of the pillar opened the shell, exposing the glass inside.

Everyone saw that there was a stick standing upright inside the column, and at this time it was only the thickness of the fingers, and it was constantly spinning.

On the stick-shaped body, countless points of light are constantly shining, like a number of fireworks exploding at the same time in the night sky, or the stars of the entire night sky suddenly burst out at the same time.

This is like the beautiful scenery of the Xinghe, attracting countless people, they never knew. The process of machining a part can be so beautiful.

Feng Tianyou helped them explain the principle of kinetic energy metallization, and then said: "Every metal particle hits the body. The kinetic energy suddenly turns into potential energy, melting the metal particles into a liquid. At the same time, some energy is released as visible light, so We can see the stars, yellow-green is aluminum, white-light is titanium, red is carbon, this time is sulfur ... The powder you provided is not very pure! "

Lao Chu stared at the expert, the expert ashamed.

Titanium has a long spectrum and emits a dazzling white light. This light is still very dazzling for a long time. Feng Dad touched a welding mask from the side, and looked at Lao Chu still squinting and gave it to him. The two were just like attending the court costume ball. The mask looked interesting.

The others were not treated so well, squinting for a moment, tears flowed, and there were light spots on the retina, so don't go over your head.

Under the continuous light. The central shaft is thickening at a speed that is visible to the naked eye, but in about five minutes, the shaft has already had its initial shape.

At this moment. The speed began to slow down, and the light spots no longer flickered in the sky, but concentrated in several places.

"Next, you must close the cover." Feng Tianyou explained, "In fact, the biggest difficulty in finishing is the observation accuracy. The next processing accuracy is far beyond the wavelength of visible light and requires x-rays to detect it, because X-rays are radiant, so the enclosure needs to be closed. "

X-rays are used to process the workpiece 360 ​​degrees. It is not enough to detect which position, it will be compensated with ultrafine dust.

Actually modern finishing. This is not to say that the "hard precision" of finishing equipment must be achieved, but that it is measured with high precision. Compensation correction is then performed to achieve the corresponding accuracy.

In this process, algorithms and procedures are the most important.

This is the difference between high-precision processing and outdoor 3D printing used by Qingchuang. Architectural printing does not require that high accuracy. As long as it is printed, it is not a matter of a few microns or even a few millimeters. Large, printing speed is much faster, do not use X-ray to detect.

After a few minutes, the printing was completed and the cooling was completed. A robotic arm took out the printed workpiece and placed it on a nearby support.

Seven workpieces took about an hour to process. Feng Tianyou was a little embarrassed and scratched his head and said, "The particulates you provided are too fine, and there are many workpieces. If there are a few coarse particles, the processing speed of the internal body is Much faster, sorry, I have waited a long time. "

The inner part is processed with coarse particles and the outer part is corrected with fine particles, so the printing speed can be much faster.

But everyone else was completely gone, and even Feng's dad was speechless, speechless for a long while.

Hearing Feng Tianyou's apology, Lao Chu subconsciously said, "We originally wanted to make one ..."

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

"Ah?" Feng Tianyou suddenly knew that he was joking, scratching his head and staring, "What should I do? I ... I don't know, I'm sorry ... I wasted your materials ... Well, why not early? Say!"

Lao Chu didn't want to say anything. He shook Feng Tianyou's hand desperately, how simple and honest he is!

The aviation expert looked down at the lines ~ www.wuxiaspot.com ~, the seven shafts that looked exactly the same, said incoherently: "Oh my God ... how is this possible that we last worked for more than a month to produce a workpiece what!"

"The times have changed, doggies." After hearing the experts say, Feng Tianyou smiled and quoted a famous quote from the game, then changed his expression with a serious expression, and said to the old Chu: "Comrade Chief, it is time to talk about compensation. It's ... "

"Ah?" Old Chu suddenly became tense, no wonder processing seven at a time, the plot is here! Is this strong buying and strong selling?

This kind of shaft body has a high processing cost. With seven shaft bodies, he can only hide from creditors during the Spring Festival this year.

Can't buy it? Fools don't buy it!

"More ... how much?" Old Chu asked.

"Ten days!" Feng Tianyou grinned at Lao Chu, looking at Lao Chu's expression was not very good, "No ... Otherwise, seven days will do, but we have two of them!"

"Ha?" Lao Chu stayed. (To be continued.)
