Description:
The Covington 8" Expandable Drum Unit 110V is a powered drum sanding and grinding unit built around an expandable drum that accepts an abrasive sleeve. The expandable drum design lets the sleeve fit tightly and run true for controlled shaping and smoothing work. In glass and lapidary coldworking, an expandable drum unit is used when you want a compliant, cylindrical abrasive surface for contouring and refining edges, curves, and inside profiles that are awkward to address on a flat lap. This style of machine is especially useful for shaping and smoothing glass forms after cutting, and for refining contours prior to moving on to finer finishing and polishing steps.
How it is used:
This unit is used as a coldworking station for shaping and smoothing glass by bringing the work to the rotating expandable drum fitted with the appropriate abrasive sleeve. It is commonly chosen for rounding and refining edges, cleaning up saw marks, and developing curved surfaces where a wheel or drum profile gives better control than a flat disc. After the desired shape is established, you typically progress to finer abrasives and polishing methods depending on the finish required.
