The main moving part inside an industrial edge sander is usually referred to as a sanding belt. This large and very powerful moving part is driven — often in both directions — by two vertical rollers. The workpiece is fed into the edge sanding machine along a long supporting table. The edge sander can be adjusted to fit the exact size of the workpiece by changing the rollers’ angle of incline, and therefore the angle of the belt.
The smooth and even movement of the belt ensures that the wood is smoothed perfectly, without any scuffs, streaks or bumps. The speed at which the belt moves also plays a part in how smooth the final finish is, as well as how long the belt lasts. Generally speaking, the faster the belt moves, the shorter its lifespan.
Sanding wood in edge sanding machines can cause a great amount of dust to be released into the air. This dust can cause respiratory problems for workers, and if it gets into the workings of other machines in the area it could cause breakdowns and premature wear and tear. This is why an extraction unit is usually situated close to an edge sanding machine. Other safety measures in place when using a woodworking edge sander include clamps to hold tools firmly in place and a cover for the sanding belt. There is also a fuse in place which will shut down the machine if it should overheat.
