Automotive Black Technology Chapter 755: : It’s time to show real sophistication!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
No matter how sophisticated a model is, it is still a model.
The components in this ladder model have been simplified in order to facilitate processing. But the essence of this model is to show the machining accuracy, not the design.
But even so, it took the technical engineers a whole day to dismantle the ladder model, measure it, build a 3D data model and double it according to Li Fanyu's requirements.
After getting the data package, Li Fanyu threw Manson Clay's ladder model directly to the engineers, and he drove to the newly completed industrial base.
All the production lines currently in use by Zhengxin are actually unable to process parts with tolerances below fifteen microns.
So if Manson Clay had given such a model to Li Fanyu a month ago, he would have had no choice but to endure it even if he was furious.
Because his skills are indeed inferior to others, and he cannot do what others make.
But now, Li Fanyu has the capital to challenge Manson Clay - because the precision machining center of the industrial base has been built!
Zhengxin Industrial Base.
Considering that the processing and production equipment here are all advanced equipment brought by the Xapp unlocked industrial base, Li Fanyu directly asked Zhu Zhu to lead people to station here.
When the A8 with the iconic license plate slowly drove into the gate, the pillars immediately greeted it.
When he learned that Li Fanyu was going to use a precision machining center, Zhuzi immediately walked with Li Fanyu to the newly completed factory building with a very post-modern appearance.
"Hey? Boss, what are you doing this late at night?" Zhu Zhu couldn't help but asked strangely when he saw Li Fanyu swinging a USB flash drive on his finger.
"Haha, try the processing level of the precision machining workshop. I can do it myself, you go out and watch over me."
Zhu Zhu looked at Li Fanyu who had a pensive look on his face, scratched the back of his head in confusion, helped Li Fanyu turn on the electric switch in the workshop, and walked out with three steps.
In the empty and bright workshop, Li Fanyu whistled easily, directly entered the Xapp, and retrieved the information of the precision machining workshop.
After seeing the usage methods and technical parameters of the equipment on the list, Li Fanyu felt confident; because he was too advanced in black technology and was afraid of being shocked if he was discovered, he selectively ignored X Super Modification workshop and X-super production line. Therefore, after the system upgrade, the technological level of the equipment redeemed by the system was lowered in order to allow Li Fanyu, a test user, to apply X technology on a large scale.
So the equipment in the precision processing workshop at this time seems to be something slightly more sci-fi than the currently commonly used precision processing equipment.
But essentially, it is a set of wire cutting machines, high-precision CNC milling machines, lathes, boring machines, five-axis machining centers and some anodizing equipment.
But in terms of precision, it can be said that the equipment in Zhengxin Industrial Base is extremely explosive!
Perhaps after reaching level 6, the system took into account the current technological level of Kong Kong. In order to take into account Li Fanyu's fair use of black technology equipment, some restrictions were placed on these equipment.
For example, the parameters on the surface of the five-axis machining centers currently in the workshop can control the minimum tolerance during the machining process to fifteen microns, which is equivalent to the most advanced machining centers in time and space.
However, the system opened a backdoor for Li Fanyu!
After investing in research and development of the system, the processing capabilities of the equipment can be temporarily improved. Performance such as processing speed, accuracy and volume.
This is so cool,
After reading it, Li Fanyu had a clue in his heart. Input the 1:36 ladder model component data in the USB flash drive into the 3D metal printer. In a short time, more than 400 No. 3 super aluminum alloy blanks were printed.
In fact, after the upgrade of the X3D metal printer, the aluminum alloy parts printed have already reached the tolerance requirement of 20 microns. But the cool Li Fanyu seems to have gone one step further!
The blank is too small,
Under the abnormal ratio of 1:36, even the original 10-meter-long part is only 27 centimeters at this ratio. And after the blanks that Li Fanyu wants to process are reduced in proportion, some are even only 3.4 mm in size!
To put it bluntly, such a "blank part" may not be as big as an iron chip removed from the part during normal machining center operation.
If it weren’t for the convenience of processing, Li Fanyu left a base for the machining center to fix when printing the blank, and he might not be able to clamp it...
Fortunately, after going through krypton gold, the five-axis machining center in the workshop has become an extremely precise thing. Otherwise, it would really make Li Fanyu's head hurt for a while.
After processing, the cutting tools of the five-axis machining center are directly replaced with a set of cutter heads that are thinner than the tip of a needle according to the size of the workpiece. Li Fanyu lay in front of him and looked at it for a long time, but he couldn't even see what the shape of the knife was!
How small do you think this has to be?
But as he pressed the button, he saw the machining center making a slight noise and starting to work at a sci-fi speed, "raising and lowering its hands" on the embryonic piece the size of a grain of rice. Li Fanyu was still shocked!
As the cutter heads on several axes moved, he could clearly see the color change on the surface of the blank!
From the original silvery white color of the aluminum alloy, it turns into a shiny bright silver as the invisible blade moves!
When the first blank was processed, Li Fanyu took out the laser caliper in the precision processing workshop for measurement, and was surprised to find...
This blank has no tolerance!
What is tolerance? Tolerance is the amount of variation allowed beyond the actual size required for a part. For mechanical manufacturing, the purpose of establishing tolerances is to determine the geometric parameters of the parts so that the variation is within a certain controllable range to achieve interchange or coordination.
Why should tolerances be established?
Because there is no processing equipment in the world that can produce absolute precision!
For example, a factory needs to make a set of screws. The outer diameter of the screw is 10mm, and the inner diameter of the nut is also 10mm. Theoretically, this size can perfectly insert the screw into the nut.
But in the actual processing process, no processing equipment can process a perfect "10mm". If the screw is a little thicker and the nut is a little tighter, it won't fit in!
This is very embarrassing,
So in order to prevent the size of the parts from being greatly affected by the processing accuracy, designers can only set tolerances on the processing drawings. Therefore, in the processing drawings of screws and nuts, we can often see that the diameter of the screw is 10mm-0.5mm, and the inner diameter of the nut is 10mm+0.5mm.
What does it mean?
It is to set a variation index for the parts and tell the workers: Damn, when you are processing, don't make the screws thicker, and don't tighten the nuts!
So tolerance, strictly speaking, is a kind of helplessness and compromise caused by insufficient precision in processing.
But the parts in front of Li Fanyu were missing! have! male! Difference!
Um...
That's not right. Maybe the part in front of him has tolerances.
But at least...the most accurate laser caliper in the industrial field cannot measure!
What is this concept?
If Li Fanyu was thick-skinned, he could call it "absolute accuracy"!
What is the use of this "absolute precision"?
The simplest thing is a watch! Why are Jaeger-LeCoultre and Rolex watches so expensive? Do you really think that a few diamonds set on it and a layer of gold on the outside can be worth hundreds of thousands or even hundreds of thousands?
Pattern!
Photography obligation!
In the watch industry, precision has always been sold!
Only when a complex and precise small machine can measure time for you with incredibly precise movements can it be worthy of its value!
“I’m-rich……”
"I'm going to get rich..."
Thinking of this, Li Fanyu murmured.
He completely forgot that he was already a rich man worth hundreds of billions.
As a person in the industrial field, when I see any equipment that can process precision parts, I will feel like Lu Bu opened Diao Chan's bellyband, Guan Yunchang rode on Red Rabbit's horse, and foolishly opened the E disk of his computer.
That is a kind of joy from the heart!
It's addictive!
So after the first part was completed, Li Fanyu couldn't stop at all!
The second, the third, the fourth, the fifth...
It wasn’t until about three o’clock in the morning that the light turned white in the east. He just used five red soft girl coins to carefully pack all the processed ladder model parts.
I returned to the R&D center with satisfaction.
When the technical engineers saw the extremely fine parts inside Li Fanyu’s soft coin folded into a triangle, their knees went weak!
And when they brought precision calipers and inspected these parts one by one, several engineers died on the spot.
These are people who deal with parts and dimensions every day, but they swear they have never seen such precise parts!
Never!
After watching it for more than ten minutes, an engineer collapsed to the ground with a "pop", wiping his tears and murmuring: "Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooow meanwthhhhhhhhhhh. How do we assemble it?"
