Belt And Disc Sander

The belt and disc are the machining surfaces where the abrasive coated belt moves in a downward direction towards the work table. Always note the direction of rotation of the abrasive disc as you only want to put work pieces in contact with the disc on the downward motion side (See attached diagram). Hazards.Belt sanders are highly effective tools for removing roughness and preparing woodwork for less aggressive tools in the process like random orbit and finishing sanders. It is crucial to belt-sand with the wood grain rather than across it. Otherwise, the belt sander's lateral action can ruin the work.
