Preforming of Beads: It is necessary to cut the gemstone material into cubes, slightly larger than the desired size. Accuracy in cutting the cubes so they are uniform in size will hasten grinding. Complete the preforming process by grinding off all corners and sharp edges until the cube is a rough sphere.

Milling: The preforms are placed in the cast aluminum 5" diameter bead chamber with a 50/50 mixture of silicon carbide and water. The 4 1/2" diameter x 1/2" aluminum head has a 3/8" recessed ring in the ceiling. Milling action is achieved by rotating the chamber with the location of the beads controlled by the milling head.

Procedures: It is necessary for the operator to develop his own procedure by making test runs and keeping records of gemstone hardness, silicon carbide grit size and milling time. Remember, soft materials require light mill head pressure and finer abrasive grit.

Caution: The mill is not recommended for gemstone material softer than 5 on the Mohs hardness scale. This is because the bead mill is a very aggressive machine.

Load: You can grind twenty 1/2" beads at one milling.

Cleaning: Chamber and head can be quickly removed for easy cleaning.

Polishing: Beads must be polished in a gem tumbler.
