Denibbing sander for surfaces
This kind of machines serves the intermediate coating of panel-shaped workpieces with profiled surfaces and profiled frames. Typical workpieces are furniture fronts and window frames. The passage width is at least 600mm. The passage height is generally at most not more than 250 mm.
The structure of the intermediate sanders for surfaces resembles the structure of wide belt sanders. A cuboid-shaped base frame carries the working table with the infeed carpet. The working units are height-adjustably hung above. Depending on the field of application the beam construction may be easier or harder. Some manufacturers use their wide-belt machine beams and construct on it whole intermediate sanders, e.g. VIET S3.
For small handicraft businesses there is also intermediate sanders in the type of an air cushion with integrated sanding brushes, e.g. LÖWER TOPSPIN F. The workpiece infeed takes here place manually by the operator.
The infeed carpet would be whetted by the brushes when sanding thin workpieces. Smooth infeed carpets made of resistant PVC with vacuum device are helpful.
