Chapter 530: Times Have Changed, Goudaner
"Where are you flying to? No, no!" Feng Tianyou got up to look for the bicycle key, "You wait here, just send someone to follow me to the shipyard."
After all, Feng Tianyou didn't need to ride his own 28 wheeler, and Lao Chu definitely couldn't let him go by himself. The father and son got on the military vehicle and arrived at the shipyard in five minutes.
There are only a few people left guarding the shipyard, an old janitor who can’t move came to open the door, after a group of people entered, Lao Chu looked at the dilapidated small shipyard, and was stunned: “It’s here? "
Their parts have particularly high requirements on processing technology, and require a 10,000-ton stamping machine to be stamped and formed. Under this pressure, the tiny gaps inside the metal can be almost completely disappeared, resisting deformation under high pressure and high temperature, and then on this basis It is finely processed, and its processing accuracy is also extremely high.
If it is processed in the traditional way, the 10,000-ton stamping machine is at least more than ten meters high, and the 16-axis machine tool used in the secondary processing process is as large as 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 saw your technical specifications, and the second-generation machine is enough. The first generation machine."
Generally speaking, they call the 3D printer that has undergone various enhancements in the Lanshen laboratory the first-generation machine, and the 3D printer manufactured with that 3D printer is the second-generation machine, which is also the current technology of Lanshen Technology. The most high-end 3D printers for mass use.
"Come and help me carry the materials." Feng Tianyou ran to the warehouse by himself and turned on the machine.
This second-generation machine is specially manufactured for Feng Tianyou. It is aimed at the manufacture of shipyard parts, so the size is quite large. It can manufacture parts with a maximum length of one meter in width and two meters in height. The manufacturing method used is aimed at metal processing. The optimized kinetic energy metallization is to accelerate the metal particles to above Mach 6, liquefy them and bond them together through the impact speed and energy. Under continuous impact, ultra-dense metal structures can be produced, and stamping is actually a principle.
The drawing provided by Lao Chu and the others is a strange shaft body with a long arm and a slight curvature. The required working temperature is between 220 degrees and 500 degrees. The material used is titanium aluminum alloy. After picking up a few big boxes, a few soldiers ran to help carry the materials.
Lao Chu and the others stayed outside for more than ten minutes, all shivering from the cold, and said to Dad Feng: "This thing is not easy to process, let's find a place to rest for a while..."
A gray-haired expert who was following Lao Chu was a little worried, and said, "I have to go in and have a look."
Before he finished speaking, he saw two soldiers coming out with something carefully in their arms.
Under the halogen lights in the courtyard, the part reflected light like a mirror. The experts around Lao Chu stared straight at him, and rushed forward immediately.
The parts processed by the titanium alloy were still very hot. Both soldiers were wearing gloves, but the expert didn't wear them.
With a unique curved shaft body, slender, slender and shiny, in the eyes of experts, she is the sexiest stunner in the world.
In fact, it is no longer possible to feel the difference with this kind of precision processing. The processing precision of the second-generation machine is 10nm, which is the thickness of a bacterium. Even a superman cannot feel the difference.
But this expert in aviation machinery still couldn't help touching it, and he was particularly obsessed with it.
"Is this... finished?" Lao Chu was completely shocked. Is this machining precision aviation parts, or is it plasticine? Even pinching plasticine is not so fast!
In fact, they always thought that Feng Tianyou was still making preparations inside, who would have thought that the processing had already been completed?
"Wind experts say this is No. 1, and there are six more that are being processed." A soldier said cautiously.
"What six? Isn't it enough to process one? Is there any defect in this?" The expert who was obsessed with the beautiful curve of the shaft body was surprised and asked hastily. Then he quickly took out the surface roughness tester to check, and the test result was perfect, two orders of magnitude higher than the required index, which made the experts' hands tremble.
Wait, if the finish is so perfect, why make another?
Is there a material structural defect inside?
"No, wind experts said that although the parts they process can achieve precision and strength, the stress will still be released. After the stress is released, the entire processed workpiece will have a slight deformation of about 1 micron, which may lead to increased wear. Therefore, according to the stress release situation, he processed seven parts with slight size differences, and replaced the parts about once every three months, so that the stress can be ignored..." These young soldiers are not illiterate soldiers, they are all A technical officer, but when he spoke, he looked drunk and questioned his own words while speaking.
This is simply a fantasy!
No, I have to go back and have a look!
As soon as they finished speaking, several of them turned around and ran into the warehouse: "Let's go get the next one!"
"Wait, you..." The others also chased in.
A machine about three meters high and two meters wide is placed in a dark warehouse. In the center of the machine is a round 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 he saw them coming in, Feng Tianyou smiled and said, "Why, do you want to watch the processing process?"
"Is it possible? Is this not very good?" Old Chu asked.
"No, no!" Feng Tianyou stood up enthusiastically, he was asked to visit the aircraft carrier, so why would 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 guys better wear sunglasses, here, it's very dazzling..."
One side of the column is opened, exposing the glass body inside.
Everyone saw that inside the column, there was a stick-shaped object, which was only as thick as a finger at this time, and it was constantly rotating.
On the stick-shaped body, countless light spots are constantly shining, like countless fireworks exploding in the night sky at the same time, or the stars in the entire night sky suddenly start to explode at the same time.
This beauty, like the explosion of the galaxy, has attracted countless people. They never knew that the process of processing a part can be so beautiful.
Feng Tianyou explained the principle of kinetic energy metallization for them, 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 part of the energy is released as visible light, so We can see dots of light, the yellow-green ones are aluminum, the white ones are titanium, the red ones are carbon, this time it's sulfur... The powder you provided is not very pure!"
Old Chu glared at the expert, who was ashamed.
The spectrum of titanium is very long, and it emits dazzling white light. This light is still very dazzling after a long time. Dad Feng touched a welding mask from the side, and in a blink of an eye, he saw that Lao Chu was still squinting, and handed it to him. One, the two of them held up their masks and watched with gusto just like attending a royal masquerade ball.
The others were not treated so well. After squinting for a while, they burst into tears, and there were spots of light on their retinas, so they hurriedly turned their heads away.
Under the continuous light, the central shaft was thickening at a speed visible to the naked eye, but in about five minutes, the shaft already had its initial shape.
At this time, the speed began to slow down, and the light spots were no longer flickering all over the sky, but concentrated in a few places.
"Next, the outer cover must be closed." Feng Tianyou explained, "In fact, the biggest difficulty in finishing is the observation accuracy. The next processing accuracy has far exceeded the wavelength of visible light, and X-rays are needed to detect it, because X-ray radiation, so the enclosure needs to be closed."
Use X-rays to irradiate the workpiece at 360 degrees. If the detection is not enough, it will make up for it with ultra-fine dust.
In fact, modern finishing does not mean that the "hard precision" of finishing equipment must be achieved, but through high-precision measurement, and then compensation and correction to achieve the corresponding precision.
In this process, algorithms and programs are the most important.
This is the difference between high-precision processing and the outdoor 3D printing used by Heqing. Architectural printing does not require such high precision, as long as it is printed, it is not a problem if there is a difference of a few microns or even a few millimeters. The diameter of the particles used is even larger. Larger, the printing speed is much faster, and there is no need for X-rays 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 the bracket next to it.
It took about an hour to process the seven workpieces. Feng Tianyou was a little embarrassed, scratched his head and said: "The particles you provided are too fine, and there are many workpieces. If there are a few coarse particles, the processing speed of the inner body will slow down." Much sooner, sorry for the long wait."
Machining the interior with coarse grain and correcting the exterior with finer grain allows for a much faster print.
But everyone else was completely dumbfounded, even Father Feng was tongue-tied and speechless for a while.
Hearing Feng Tianyou's apology, Lao Chu subconsciously said, "We just wanted to make one..."
The reason why I brought so many ultra-fine dust materials is because this kind of workpiece has a good product rate, and once it is processed and damaged, it must be replaced.
"Ah?" Feng Tianyou suddenly knew that he was making a joke, scratched his head, and said with wide eyes: "Then what should I do? I... I don't know, sorry... I wasted your materials... Sigh, why not earlier explain!"
Old Chu didn't want to say anything anymore, he shook Feng Tianyou's hand desperately, what a simple and honest comrade!
The aviation expert looked down at the seven identical shafts lined up in a row, and said incoherently: "Oh my god... how is this possible, it took us more than a month to process a workpiece last time!"
"The times have changed, son of a bitch." Hearing what the expert said, Feng Tianyou smiled and quoted a famous quote in the game, then changed a serious expression, and said to Old Chu: "Comrade Chief, it's time to talk about the rewards." It's..."
"Ah?" Lao Chu suddenly became nervous, no wonder he processed seven at a time, the conspiracy is here! Is this a strong buy and sell?
The processing cost of this kind of shaft is extremely high. If there are seven shafts, he will have to hide from creditors everywhere during the Spring Festival this year.
Do you want to buy it? A fool would not buy it!
"How much...how much?" Old Chu asked.
"Ten days!" Feng Tianyou grinned and looked at Lao Chu, seeing that Lao Chu's expression was not very good, "No...otherwise, seven days is fine, but there are two of us!"
"Huh?" Old Chu was stunned.
