Can you actually get an acceptable polish on that Jang801? Is it tough to program? Just interested since this seems like a difficult thing to do given the nature of gem stones.

The key to polishing on automatic machines is the lap and compound used.
That is one of the reasons most commercial stones only get a 14K final polish. It is aggressive enough to actually place and ut the facets, and leave an acceptably bright 14K finish. So "brillianteering" (diamond terminology), and polishing are actually the same step. m This is also the way hand cutting also works in many high production shops.
For those unfamiliar with the term brillianteering.

Sure, as good as by hand. Same processes applies. Software runs gemcad files. As the index and lap rotation run counter-clockwise and no reversing direction of the lap some angles above 55 degrees can be problematic with polishing. Reversing the lap direction would eleviate it, but I have found alternative methods to resolve.

3D means - three dimensional view In the fully automatic faceting machines helps in inclusion mapping in rough before faceting.
Even Jang machines(advanced) do the same.
But I am not getting the contact details of suppliers of these machines.
Hoping kind and positive response pls
I am not aware of any AI Jang machines that plot rough to avoid problem areas. The models I know of have a two dimensional display of the set facets it is currently cutting.
I would suspect that if there was something out there it would be presented for purchasing. I remember watching some youtube videos a few years ago about machines claiming to do what your asking but they appeared to be pretty much like Jang(advanced).
I can not count the number of times I have been approached by someone wanting me to participate in reverse engineering the Jang 801 not so much the hardware but the software.

The diamond industry does have machines that plot inclusions and calculate the best cutting solutions. I knw some people in Idar have used such machines for colored stones.
Almost all the diamond cutting factories in India now use such tools.
Look at Sarine Technologies from Israel who are the leaders in this field.

If you know Jang's why not contact?

Saw an interesting article quite some time ago (like 2 decades?) about an Israeli company using computerized machines to cut emeralds. They might have moved forward a lot since then, unless cheap labor elsewhere put them out of business...

Just like diamond cutting, The emerald cutting industry is now predominantly in India.
Steve if incase this is true and I believe it is as well, why would the OP be in search of an Ai machine to put in service in the same arena? I know in fact that Jang placed many automated faceting machines for cutting melee sizes at 100-200 pieces a pop in India.
To my knowledge there is no machine that is fully automated to be a do all facets of faceting. Cutting, Polishing even preforming can be automated.
I can be wrong, please someone point me to that robot.
