I have to say that the car model sent by Manson Clay is too exquisite. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In the field of manufacturing and processing, it is not the ability to make a complex thing bigger. But if you want to do it smaller, that's real kung fu!

When Li Fanyu was in junior high school, he learned an ancient text called "The Story of the Nuclear Boat", and it is not an exaggeration to use the exquisite words to describe the walnut micro-carving in it to describe the fire ladder model in front of him, which is only about half a meter long.

The chassis part of the model is just that of an ordinary car model, nothing worth noting. But the tops, under a magnifying glass, look like a real fire ladder;

The main frame, ladder arm, outriggers, and hydraulic system all seem to be the same as the real one, the hydraulic telescopic rod of the lifting part of the ladder seems to be fully linked, and the telescopic ladder part can be seen by the rubber instead of the chain and the tiny slider......

Although the whole ladder structure is not large, it is extremely complex, which can be called ingenious!

Such a thing is placed here, even Chen Yuhan and the two security guards who don't understand processing technology are deeply shocked.

Chen Yuhan squatted beside Li Fanyu and watched for a long time before closing his slightly open mouth, "Dong Li, there is a remote control here......"

Li Fanyu was also attracted by the precision expressed on the car model, and only picked up the remote control after listening to Chen Yuhan's reminder.

The remote control is actually completely modeled after the ladder control system. The levers and buttons on it have been simplified, but they are almost identical to the real ladder panel.

Picking up the remote control and turning on the switch above, Li Fanyu pressed the ladder lifting button.

“……”

Watching the ladder slowly rise at a steady speed, with an almost imperceptible tremor, Chen Yuhan and the two security guards' faces were a little weird.

Although it is not good to praise competitors in front of Li Fanyu, but in their hearts, the three of them all gave out a word!

Li Fanyu looked at such a thing, and he was also angry and funny in his heart.

This Manson Clay, giving himself such a thing, is clearly showing off his muscles and showing his high-end manufacturing process!

Li Fanyu shook his head helplessly, and waved his hand to the two, "Load, carry, I'm going to the R&D center." ”

"Come on," the two security guards hurriedly repacked the model and followed Li Fanyu downstairs.

……

When Li Fanyu drove to the R&D center, he happened to catch up with the engineers to change groups for dinner. He came to the cafeteria directly with the box with one hand.

The four goods of Sanxueba and Wang Rui have a fixed lunch time every day, and they always like to force each other on the canteen table. Li Fanyu didn't have to bother to find them directly in the crowd.

Why don't you bother with it?

Because watching these four goods is forced to belong to the conservative program at lunchtime, the engineers love to watch it.

"Yo, Brother Fan, what are you carrying?" Wang Rui sat facing the door, and when he saw Li Fanyu coming in, he hurriedly got up and asked.

Li Fanyu didn't speak, he directly put the car model on the dining table, opened it in front of them, and personally took the remote control to show the lifting of the ladder.

The four of them are all the top students among the top students, and when they saw the vivid and ingenious model, they actually worked with a very stable attitude, and they saw the key to the problem at a glance.

Look at the ladder legs, two millimeters in diameter, with the ring sleeve of this small electric hydraulic pump, if the tolerance is not controlled within 20 microns, the ladder will definitely shake when it is extended!"

"Awesome, I saw a Swiss tech nerd on the Internet before, and it took 105 days to make a mini engine with a 32-bar bar of just over 20 centimeters. That's pretty awesome, holding grass compared to this, it's just scum!"

"Awesome, really awesome, Brother Fan, this is what you did?"

Li Fan grinned: "Do you think I have such idle kung fu?"

Hearing Li Fanyu's denial, everyone's faces froze.

Li Fanyu shook his head helplessly, took out the postcard in the box, and photographed it in front of everyone.

Xu Fufang is proficient in German, and when he saw that everyone was confused, he picked up the postcard: "Dear Mr. Li Fanyu, we believe that all machinery that is closely related to the user's life needs precision and reliability as its essence. I hope that after you have seen this model, you can have some insight and awe of this field. Yours sincerely, Mansenkle von Schmidt. ”

After reading the postcard, he frowned and looked at Li Fanyu, "Brother Fan, this is sent by Manson Clay Company?"

Li Fanyu nodded.

", what do you mean, what is this? Say our technology is not good?" Liu Qing slapped the table and got up and shouted.

Wang Yu pulled him back to his seat, looked at the car model in front of him, and said slowly: "Why are they doing it, it may be that they are thinking that we haven't started research and development yet, and they will disgust us with this thing." We are more than halfway through the R&D process, and the big guys are working hard, and making the finished product is the best response to them. ”

Li Fanyu nodded, "Brother Yu is right, Li'er is this Li'er." But people have already sent the war book to our house, and the courtesy is still exchanged, so we have to pay a salute in return. ”

"Brother Fan, what do you mean?" Xu Fufang's brows tightened.

"You took out a few idlers, dismantled this thing for me, and made a data model according to their structure. Hmph, since he can make a model of a real ladder, let's make him a smaller, more precise! Isn't it 1:18, let's give him a 1:9!"

“……”

Although the words were quite uplifting, the group of engineers around them could only laugh dryly.

"Li Dong," a technical engineer spoke, "it is not difficult to model, it seems that his car model is also simplified according to the real ladder after a certain structure." But...... I feel that according to the current processing technology, the ability to make a 1:18 model of the ladder with such a complex structure already represents the pinnacle of modern processing technology. ”

"Yes, senior brother, if we make a 1:9 model, the body length of such a complex thing can only be more than 20 centimeters...... Not to mention, the outrigger now looks only two millimeters in diameter, and the tolerance to achieve the stability of this model ladder when it is extended is controlled to about 20 microns. It is important to know that even the best five-axis simultaneous machining center can only control the tolerance of processing delicate and small parts to more than 15 microns. If you want to make a 1:9 model like this, then ...... How to make such a small and delicate part, not to mention, the tolerance of ten microns ......"

Li Fanyu waved his hand at him, "Manson Clay is different from our previous competitors, this company is a bit interesting. If you don't play with us in literary fighting and martial arts, you just want to disgust us with their best precision machining. It's like a duel between two knights. The other party has already thrown the gloves in my face, and if I don't take out my sword to fight this guy, how will I raise my head and behave in the future? I'll figure out the rest!"

Li Fanyu waved his hand and set the tone.

Seeing the engineers helplessly put down their chopsticks and go directly to the tools to disassemble on the spot, Li Fanyu's eyes narrowed.

Hmph, play this with me?

What about being a fool?

The master came all the way with Rengang, afraid of you?!
