This marble polishing machine is powered by 3 engines and plugs into a standard wall outlet. The machine ships with 3 grinding cups which screw onto each of the 3 drive shafts. These cups will polish marbles from a bit under 1" up to 2" in diameter. Your local hardware store will have an abundance of pipe fittings, adapters and reducers that can be used as grinding cups to polish any size marble you wish.

Silicon carbide grit is used to grind damage away, polishing compound provides the wet polished finish. Grit/compound is not included, but easily obtained - we'll tell you where). Illustrated guide is included.

The machine can also be fitted with optional diamond cups - diamond dust is incorporated into the cups so they grind without the grit!

As illustrated by the additional images, this machine is capable of taking marbles so badly damaged the core cannot be seen, and restoring them do a mint, polished surface. Also works with machine-mades.
