The surface to be sanded is completely removed by the sanding process. This happens quickly by sanding thin surfaces such as varnish and veneer. It can be caused by unevenness of the workpiece at even and fix contact with the sanding belt. The sanding pressure on the raised parts of the workpiece would be higher than on the remaining area. This results in a higher material removal, which can lead to through-sanding. Sanding of flat surfacesThe solution of the problem would be a constant sanding pressure on any part of the workpiece. This can be achieved by means of:
Failure point workpiece edgeCritical are the workpiece edges as well. At these points the sanding belt is no longer completely flat on the surface but 'wraps around' the edge slightly and may cause the edge to be sanded 'round'. Sanding through the workpiece edges can be prevented by:
