Thinner veneers and thinner lacquer coatings on warped support plates with tolerances require the utmost care during an automatic sanding process. In spite of these existing tolerances an even pressing-on of the sanding belt on the whole surface of the workpiece should be guaranteed up to the edge area.

Thanks to the CSD® pressure beam system we are in a position to adjust the press-on force of each individual press-on element in an accurate way in accordance to the size of the workpiece surface laying under this press-on element. Fully automatic and dynamic - without any intervention of the operator. By this a regular pressure build-up up to the edge area is ensured - independent from the workpiece shape. If slightly overlapping edge bandings should be smoothened, the press-on force of the press-on elements in the edge area could be increased - and this also in a asymmetric manner.

Encapsulated integrated electromagnetis guarantee maintenance-free press-on elements over many years as these only have got one unique circuit switch - the lifting armature.

The press-on elements are soft-running and have a precise bearing and could compensate big thickness tolerances of max. 2 mm.

The animation shows the function principle of the CSD® pressure beam with a simulated passing through of the workpiece through the machine. The height of the green press-on elements symbolizes the press-on force which adapts dynamically to the surface of the workpiece which is laying under the respective press-on element. The CSD® pressure beam is maintenance-free. CSD©-Animation	This picture shows the common sanding technique with pneumatic pressure cylinders. It is impossible to make an exact pressure dosage of each individual segment of the pressure beam with compressed air. It is only possible to enter 100 % (total pressure) or 0 % (no pressure) on the individual pressure beam segment. Consequently, a sanding through cannot be avoided in critical areas such as edges resp. openings in the workpieces. Moreover, the pneumatic pressure beams are subject to maintenance due to pollutions caused by oil, water or dust in the compressed air.
