People at the scene and netizens in the live broadcast room all said that it is impossible for a machining center to achieve such machining accuracy by "cutting" alone.

Because the highest processing accuracy of this "cutting" is 0.0001mm, 100 nanometers.

Although there is evidence that the highest manual 'grinding' accuracy of humans can reach 50 nanometers, the creator of this record is Ye Hui, who specializes in grinding ultra-precision parts for Daxia Aerospace Industry.

But he relied on his special talent and it took him more than twenty years to achieve this level. How many Ye Huis are there in the whole Daxia?

You use the 'cutting' method to achieve a processing accuracy of less than 0.0001mm, or less than 100 nanometers. Isn't this too exaggerated?

If this is true, then what is the use of world-class grinding craftsmen like Ye Hui?

Faced with the questioning voices at the scene, Lin Feng did not panic, but stretched out his hand and made a quiet gesture.

Seeing this, the people who were questioning could only quiet down and give Lin Feng room to speak.

“First of all, it is not surprising that the grinding accuracy of our seven-axis machining center can reach 0.0006mm.

Because decades ago, workers in the island country could manually file out high-precision parts with a surface processing accuracy of 0.00068mm, or 680 nanometers.

There is no reason why our Xingtu five-axis machining center cannot do this, so although the precision of the Xingtu seven-axis machining center's grinding process is a bit exaggerated, this is the reality. "

After hearing Lin Feng's words, the people at the scene and in the live broadcast room were somewhat surprised.
But considering that the workers on the island can manually file out parts with a precision of 0.00068mm nanometers, it does not seem unacceptable at this time.

And looking at the appearance of the seven-axis linkage machining center at this time, it is clearly two robotic arms that imitate the structure of human arms.

Humans can manually file out parts with a precision of 0.00068mm, so it seems possible that a robotic arm can do the same.

In response, Lin Feng did not stop talking. When people nodded gently, he continued:

“As for why the machining accuracy of ‘cutting’ can reach below 0.0001mm, it is actually due to the fact that we use a brand-new cutting equipment.

That is our 'Nano Flying Knife Cutting Machine'!"

When Lin Feng said this, the structural picture and brief introduction of the 'Nano Flying Knife Cutting Machine' appeared on the projection screen and the live broadcast room behind him.

“I believe many people have read the novel The Three-Body Problem, or have heard of the concept of ‘Nano Flying Knife’ and know how terrifying it is.

The prototype of the nano-flying knife in the novel is actually single-walled carbon nanotubes!"

At this time, the projection screen behind Lin Feng and the pictures in the live broadcast room changed again, becoming an introduction to single-walled carbon nanotubes and multi-walled carbon nanotubes.

“There are two types of carbon nanotubes in the world: single-walled carbon nanotubes and multi-walled carbon nanotubes.

A single-walled carbon nanotube is a graphene rolled into a circle, ultimately forming a carbon nanotube with only one wall.

Multi-walled carbon nanotubes are carbon nanotubes with multiple walls and multiple graphene rolled into a circle.

The structure of the multi-walled carbon nanotubes is like a tube inside a tube, and then the tube inside another tube.

This process of stacking and stacking creates multi-walled carbon nanotubes with different performance parameters and slightly different names.

In terms of tensile strength and comprehensive performance, the strongest carbon nanotubes are naturally single-walled carbon nanotubes.

After all, there are no other carbon nanotubes in its stomach, so it won’t have diarrhea when it is working because of something in its stomach causing trouble.”

“Puchi…” Upon hearing Lin Feng’s vulgar metaphor, netizens at the scene and in the live broadcast room couldn’t help but burst out laughing.

Although Lin Feng's description is a bit vulgar, it is indeed the truth. In fact, the performance of single-walled carbon nanotubes crushes multi-walled carbon nanotubes in all aspects.

Not to mention the superior electronic performance, just talking about the elastic modulus, the elastic modulus of multi-walled carbon nanotubes can only reach 300~1000G Pascal.

The elastic modulus of single-walled carbon nanotubes can reach 1000~3000G Pascal, which completely crushes multi-walled carbon nanotubes.

At this time, the single-walled carbon nanotubes used in the Xingtu seven-axis linkage processing are naturally the 3000G Pascal single-walled carbon nanotubes.

So theoretically, if we weave them into a 'rope' in the same way as ropes, we can actually make the core component of the space elevator, which is the 'rope to the sky'.

Of course, it is theoretically possible, but the output is too low, and there is no way to produce such a long and large-scale "rope to the sky".

And if you really want to build a space elevator, having the 'rope to the sky' doesn't mean the end. It just solves one of the biggest problems, and there are still many problems to be solved.

In this regard, the people at the scene naturally did not think that far. Only those with a keen nose thought of using single-walled carbon nanotubes to build a space elevator.

“As you can see, this is the key to why our Xingtu seven-axis linkage machining center can achieve such machining accuracy.

There is actually only one key thing, which is a single-walled carbon nanotube wire with a diameter of 2 nanometers and a maximum length of 16 meters.

As for how to process a single-walled carbon nanotube wire, it depends on the cutting principle of our tools.

Anyone who has studied physics knows that when our knives cut, they are not actually cutting, but the thin side of the knife is squeezing the surface of the object.

When the surface of the squeezed object cannot withstand the pressure, it will break, and this breaking process is naturally continuous.

The final result is that the object is cut into two halves, which gives us room to develop special processing tools.

So our 'Nano Flying Knife Cutting Machine' uses this principle. We straighten the single-walled carbon nanotube wire with a diameter of only two nanometers to form an invisible blade.

The robotic arm will then pass this two-nanometer single-walled carbon nanotube line across the part, allowing it to pass through the metal part and cut off the unnecessary excess parts of the metal part!"

While Lin Feng was speaking, the picture behind him showed the process of metal parts being cut by an invisible blade.

When the robotic arm used the 'nano-flying knife cutting machine' to cut through the metal parts, nothing seemed to change.

This is because although the surface of the part is cut into two parts, the surface is too smooth.

Therefore, the two parts of metal still have adhesion, which is why the parts did not split apart on the spot.

But the parts and the excess parts that were cut were ultimately split into two parts by the invisible blade of the single-walled carbon nanotube line, and this cannot be faked.

So next, when the other robotic arm touched the excess part, the excess part fell off directly.

Seeing this, both the people at the scene and the netizens in the live broadcast room, they all gasped.

There is no other reason, it's just that the 'Nano Flying Knife' is so powerful, it only takes a light stroke.

That metal part seemed to be made of cake, and the excess and useless parts were cut off without any resistance.

This invisible blade is too terrifying. It can't even withstand those metals that look very hard. If it is used to cut people, wouldn't it be invincible?
As people thought of this, fear flashed across their eyes, fearing the powerful effect of the 'Nano Flying Knife'. (End of this chapter)
