ABSTRACT:
A belt sanding machine for plane-sanding of a surface and comprising two sanding units and, as seen in the feed direction, in front of, between and behind these sanding units guides or pressure beams for setting the sanding depth, and a table (9,10) for pressing the workpiece against the sanding units and pressure beams. The table is designed in such a way as to allow both dimensioning or adjusting a workpiece to an almost exact plane-parallel shape and finish sanding with an accurately predetermined sanding depth regardless of whether the thickness of the workpiece varies locally.
The sanding machine is characterized in that the table includes a number of pressure studs movable towards and away from the sanding units and the pressure beams the pressure studs being arranged to be actuated by a pressurized fluid.
