so in order to make those cabs you make, you need a saw to cut the shapes, a grinder to smooth the edges, and what else? also for the grinder, do you need different wheels like 60/90 wheel, 220 wheel and so on? Then how do you polish them once they are ground down smooth?

John, diamond wheels are great! They are also tough, and fragile. A grinding wheel can be made into a shape where diamond wheels cannot. I have found, a 100 diamond wheel, and a rubber wheel with belts for sanding from 220 to 1200 with a leather belt for the rubber wheel. That is all you need for perfect cabachons, cabochets, and general stone work. Keep the diamond wheel wet, it lasts forever. With the belts, sand a piece of brick before sanding stones. It breaks the peaks off the grit and they sand smoother. A water drip makes them cut more agressivley. All one needs is a bench grinder, diamond wheel, rubber wheel, sanding belts, leather belt, an improvised water drip. Voila'. Great things can be made from humble machines.

doc do i have to dress the new diamond wheel i notice alot more edge chiping useing it ,,there not big but its leaving a very rough edge,, unlike the carbide wheel they would come out with close to a razor edge,, i did get a 80grit diamond wheel, maybe it just has to break in ?

80 grit is pretty agressive for a diamond wheel. You will get chipping. 100 grit chips a little less, 220 chips very little but it takes forever. You will have to take the chipping into consideration when you make the grind. I would sand with 220 after using the 80 grit. Sooner or later, the high points will wear down. You might also grind from the bottom of the stone to the top. That is how most commercial cabbers cut.

John, a good while from now, when the 80 finally gets real dull, replace it with a 100 grit. It cuts about the same with a little less chipping. Grinding stones will chip them some, so sanding belts will always be needed. Too fine and it takes all day, too coarse and it chips away. The quest to find the perfect solution.
