The Four Station Expandable Drum Unit is a versatile machine that allows the user to move through grinding stages without changing the wheels. The angled expansion slots through the rubber rim of the expandable drum allow it to expand when rotated, thereby locking the belt in place. The drum surface flexes to the contours of the gemstone quickly removing grinding flats and scratches. Accessories include four (4) 3" x 8" sanding belts (1-each 100g, 220g, 400g, & 600g), belt guard, and instructions. The hoods are easy to remove for cleaning or wheel changes. The water valve takes 1/4" OD plastic tubing for gravity water flow or 1/4" copper tubing for pressure systems. Spray nozzles under the hood wet the entire wheel face. This unit ships mounted on a rustproof aluminum-topped Lam-I-Cushion base. |
