Cutting/working with ruby in a DIY setting.

>>1203481
I would try to use a dremel. But I have no experience either.

Ruby has a hardness of 9 Mohs, same as corundum. Diamond is 10 Mohs.

You might be able to work it with diamond wheels.

Ruby...the second-hardest metal

Dude, ruby is a vitamin.

>Would it be possible to carve them into stuff in a home setting without special jewelers tools or is this too impractical.
It's possible, but it would be a hassle. How much of a hassle you're willing to go through with naturally depends on you.

>stone or stone like materials
Single crystal aluminum oxide is not much like stone at all. It's among the hardest gemstones. It is enormously harder, tougher, and more difficult to work with than even hard stones like granite. Small crystals are the most common abrasive for a reason.

An angle grinder probably spins much too fast. Even with a diamond disk under water, surface speed should be relatively low. It will cut, but it will be slow. A dremel with a diamond cutting tip will likewise remove material, but it will be slow.

Corundum sandpaper will not work at all for smoothing. It's the same material, and the small grains will handle the contact worse than the big piece. Once you have it smooth, it might work as a buffing compound to make it shiny though. Diamond or silicon carbide abrasives are harder.

Angle grinder is way too fast. A tile saw with a diamond blade can work, if you make a zero-clearance insert for it (without ruining coolant flow somehow). Craigslist always has a few tile saws up for cheap.

If you plan on trying to facet, though. that's not going to happen without a lapidary machine. Not well, anyway. They're not HORRIBLY expensive, considering the potential cost of the raw materials they're meant to process, but they're not exactly priced to be disposable, either.

So an angle gringer spins too fast resulting in a slower cut.
Did not expect this but you seems to know what you are talking about.

What other tool would be better to do this? Something slower with more tork?
Tnx for the silicon carbite tip.

The zero clearance for the tile saw is dooable, im not planning on making facets.
Like always it seems that i will spend more on tools then on the raw materials themselves.

I use my pottery wheel as a lap wheel. I glue diamond grit pads onto plastic bats, affix them to the wheel head via the bat pins, and set up a water drip feed over the pad with a bucket of water and plastic tubing. If you're considering getting into both ceramics and glass/lapidary work, this is a nice setup.

No, it's a shitty web cartoon.

Okay so I've cut some rediculously hard and expensive research crystals before, and what we use to do precise cuts is either a slowspeed diamond wheel in lubricated water, or a diamond wire saw with lubricated water.

You're never going to get the wire saw, but maybe you can rig up a ghetto diamond saw or find one for sorta cheap.

Shut you whore mouth.

No Ruby damces toples on Saturday down the street.

>Same as corundum
Because Ruby emerald sapphire ect are all corundum with different impurities that give them color

Yea everyone derps sometimes

How cheap?
Because you can still carve what you want in plastic, make a mold and pour ruby colored resin.

I hear that tungsten carbide is about as hard or a little bit harder than ruby. The ball in ballpoint pens is made of tungsten carbide. So in theory, all you need is a pen. Or a thousand.

you know what you have to make with the ruby

>>1204620
>Ruby emerald sapphire
Ruby, sapphire, and padparadscha are all forms of corundum, which is crystalline aluminum oxide. Emerald is an entirely different mineral, beryl (beryllium aluminum cyclosilicate) with green impurities.

Where are you getting 1000+ carat shit from?

OP indicates that he has a hookup with QC failed boules from a laser tube manufacturer. Rubies are relatively easy to grow to large sizes these days industrially.

For the time it actually cuts, it cuts faster. The problem is that grinding generates heat at the point of grinding, and a harder material and higher abrasive surface speed generate higher temperatures. Grinding ruby with diamond at 150mph (typical of an angle grinder) would probably set the diamond on fire, but even if it didn't, it would chew up the wheel pretty fast. Recommended masonry cutting speeds are based on balancing productivity against abrasive life, and the water often used serves to help keep things cool. Something like a purpose-made masonry saw with water cooling would probably work best for the store-bought options, though since it's optimized for conventional masonry, you'll still probably have rather short blade life. Some kind of extra-slow custom rig as mentioned here >>1203982 could give you decent blade life.

I wish I had his hookup. Laser ruby is still super expensive on fleabay.
