Looks like one of the high speed sanding rigs. You glue different grades of sanding disk to the flat wheel and use it for rapid smoothing of flats like T-eggs, agates and pet wood. The one I had you would run dry so you had to use it outside with a vacuum and mask to avoid silicosis. Final polish was done on a bull wheel which was a big soft leather coated wheel that ran much slower. High speed sanders are great rigs and sometimes fairly expensive but are a pain to use because of the dangers associated with dry sanding. Mine was more of a home made rig that came from a thunderegg rch in Oregon where they used them to polish eggs for their rock shop. Yours looks much more like a good commercial setup.....Mel

I have one. If you are not careful it will fling the almost finished slab out of your hand and smash it on the floor. And they get hot fast too, so best have a few slabs lined up to keep the heat down.

And especially keep your fingers out of the way. The edge is moving 72mph and will cut flesh. It might have a nut with 2 holes for a spanner wrench at the center of the disc, and use sandpaper discs with center holes. If so you don't glue the discs on. First, and only one I ever owned had the glue on setup, I changed it over to screw on fairly quickly.
