Sanding Machine 

a woodworking machine for sanding parts and articles made of wood and wood materials. Sanding machines are divided into disk, belt, drum, bobbin, vibratory, and polishing types depending on the type of abrasive tool, the shape of the backing to which the abrasive paper is applied, and the purpose.

Depending on the workpiece feed motion, sanders may be fixed or traverse types. In the former, either the abrasive paper or the workpiece executes a reciprocating motion; in the latter, the workpiece passes through the working zone of the abrasive paper. Machines used for polishing varnished items are of the fixed type. Varnished surfaces are usually sanded on vibratory sanders, in which the abrasive paper executes an oscillating motion together with its clamping device at a rate of approximately 1,400 vibrations per min. The most productive types of sanders are wide-belt traverse types and drum sanders.
