Stock removal on a widebelt sander is determined as much by the abrasive belt as by the machine. Each abrasive belt is designed to remove a certain amount of stock and if that amount is surpassed,
the life of the belt is affected and workpiece burning or other heat issues may occur.
As a rule, use the lower grit belts for heavy stock removal (36-80 grit belts can remove approximately 1/8 to 1/32 inch respectively)
and medium grit belts for lighter stock removal (100-120 grit belts can remove approximately 1/32 to 1/64” respectively).
Belts in grits from 150 on up should only be used for finishing and are not considered cutting belts.
Other factors affecting stock removal are: abrasive belt speed, type of sanding head, feed speed and horsepower.
