Hand rubbing nuclear fusion live in the wilderness

Chapter 277 Inspiration from Netizens

With the prepared sapphire glass, Han Yuan came to the industrial equipment workshop.

There is enough equipment here to process brick-shaped sapphires into a wide variety of shapes.

A piece of sapphire glass with a length of [-] centimeters and a height and width of nearly ten centimeters is enough to make dozens or hundreds of sapphire excitation rods.

Line drawing, sawing, honing, polishing.

The process of processing sapphire light source excitation rod is actually similar to that of processing gemstone jewelry, but the processing accuracy is much higher than that of general gemstone jewelry.

The optical quality of the gem rod is very high, although it is a small round rod.

But he needs to grind and polish the two ends of the laser rod into an optically parallel plane, the parallelism is required to be better than ten seconds, the flatness is not lower than a quarter of the aperture, and the perpendicularity between the end face and the rod axis is not less than one point.

This is a requirement on both sides, which is much higher than that of ordinary jewelry.

As for the sides, the sides are not polished, but will be blurred to prevent parasitic laser oscillations.

After all, the degree of polishing and cutting of jewelry cannot be seen by the naked eye after reaching a certain level.

The laser bar used for the light source of the lithography machine is different. Once a certain surface does not meet the requirements a little bit, various problems such as laser scattering and focusing failure will occur.

From the definition of quality, artificial sapphires are far superior to natural gemstones in terms of purity.

But the value is far less than natural gemstones.

Humans are like this, as soon as something is man-made or can be mass-produced, the value will immediately plummet.

After two days of busy work, Han Yuan still hasn't got the sapphire laser rod out.

The processing of this thing was more troublesome and difficult than he expected.

Although there are multiple and complete processing technologies in his mind, the processing equipment he is currently using is too low.

Although the M1-level multi-axis linkage processing instrument has many functions, it can be compared with the CNC machine tool in this respect, but it is far inferior to the CNC machine tool in terms of machining accuracy.

Therefore, when grinding and processing the flatness aperture, the Korean won tossed and scrapped seven or eight sapphire glass rods, but none of them met the requirements.

The whole piece of sapphire has been cut into pieces by him, and the discarded sapphire laser rod was directly thrown into the trash can.

Although only two sides of the sapphire laser bar are processed, the processing requirements for flatness are extremely high.

Calculating the flatness error based on interference fringes is the way he currently uses to check whether the flatness of both sides of the laser rod meets the requirements.

If there are interference fringes that bend in one direction during measurement, then adjust the position of the flat crystal to make several interference fringes appear, then the approximate value of the flatness error is: f=(λ/2)×nλ.

This is an eternal theorem, and it is also the calculation method that needs to be used in jewelry processing.

At present, the Korean won is stuck at this step, which is also the last step.

The flatness accuracy of the processed sides does not meet the secondary precision requirements, and the mapped aperture number always exceeds the standard when detecting the aperture.

Such a sapphire laser rod will produce more serious scattering phenomenon when used.

That is to say, the laser beam projected through the laser bar will fork.

It's as if the urine is divided into two, or three, or four when urinating.

The scattered laser light from the fork will seriously interfere with the light mirror in the lithography machine, which will cause problems with the engraving light knife.

After destroying another ten-centimeter-long sapphire laser rod, Han Yuan sighed, and threw the unqualified laser rod in his hand into the trash can in the corner, making a crisp sound.

It can't be done like this anymore.

If this continues, the entire piece of sapphire may not be able to produce a qualified one after grinding.

Why is it so difficult to process the flatness aperture?

"It would be nice to have a CNC machine."

Sighing, Han Yuan got up silently and cut a long strip of crystal from the sapphire again, held it up in front of his eyes and observed it carefully, thinking about how to improve the processing method.

In the simulated space, Han Yuan sighed, and on Earth, the audience in the live broadcast room also sighed.

Watching him ruin sapphires like this, even if it was artificially made, the hearts of the audience in the live broadcast room were still broken.

【I don't want it anymore? 】

[Holy shit, can you give me the ones in the trash can? 】

[Is this the top boss? What a luxury, such a big sapphire, just throw it away. 】

【Watching the anchor ruin such a big sapphire, I feel so distressed that I can't breathe by myself╥﹏╥】

[The discarded ones are used to grind the sapphire ring noodles, anchor. 】

[For such a large piece, it is estimated that the surface of the ring can be ground for several hundred yuan. 】

[What's wrong with the ring, it's awesome to get a sapphire ring or a sapphire bracelet. 】

[Artificial goods, the value is not high, besides, the anchor is doing scientific research, why do you want to quit? 】

[I used to grind an imperial green ring surface with a glass bottle of water, and then lied to my wife, saying that it cost 10,000+ to buy it, and the diamond ring was omitted. She still doesn’t know (ov)ノ]

[I made a mistake, the upstairs is awesome. 】

[You have the sapphire, I have the glass bottle of Bravely Traveling to the End of the World! 】

[Talent!Hope your wife finds out soon. 】

[If you find out, you will probably be punished by domestic violence. 】

After scrapping several sapphire sticks in a row, Han Yuan also temporarily stopped processing, thinking about how to improve, while looking at the virtual screen.

Most of the time, stubbornness can't handle a thing.

If it is one or two failures, it is okay, but five or six failures in a row, if there is no problem with the material, then there must be a problem with the processing method.

Just in time, he saw the use of beer bottles to process imperial green jadeite as a ring to fool his wife, and he couldn't help laughing.

He had also seen a short video of using glass bottles to process ring noodles before, but he didn't expect that someone would actually do this.

If this was discovered, it would be reasonable to be beaten up by his wife.

The netizen's shrewdness eased his depressed mood a lot.

"Wait, water mill?"

Smiling and laughing, the unfinished smile on Han Yuan's face suddenly froze.

The processing method he is currently using is to first cut with an M1-level multi-axis linkage processing machine, then manually polish once, and then enter the [-]-level dust-free workshop to handle the remaining steps to prevent dust pollution.

However, the semi-manual and semi-mechanical polished sapphire rods are not up to standard at all on the plane.

"If the last step is replaced with a fixed water mill, what will be the effect?"

Thinking of this, Han Yuan quickly searched and flipped through his mind.

As he searched and flipped through, Han Yuan's eyes gradually brightened.

"It seems to be okay."

Compared with normal abrasive grinding and polishing, the use of water grinding can achieve nano-scale polishing at the top level.

It's just that the conditions are relatively harsh, and it is necessary to use diamond grinding fluid with a particle size of W2 for processing.

But his requirements cannot reach the nanometer level, and the precision of the laser rod required by the two-level precision is at the micron level.

This level of precision can also be achieved with larger particle size diamond grinding.
