The series HEESEMANN OSR encompasses machines, which have been especially developed for sanding workpieces with transversal texture.
Fine sanding of
All workpieces mentioned above have parts in them in which the wooden fibre goes across the direction of sanding of the lengthwise sanding belt or cross sanding belt. One of both units will leave traces of sanding on the workpiece transversally to the wooden fibre. These traces are especially visible when treating it with dark stain.
Solution - The OSR technology
The core of the OSR machines are two subsequent orbital sanding unit of the OSR type of the new generation (from about 2016 on). With the first OSR unit the transversally going traces are resolved on a large scale. The second unit ensures the finish.
The orbital sanding machine OSR I only serves the fine-machining of the workpieces mentioned above. With the help of the combined calibrating- and fine sanding machine OSR II the complete processing of the workpieces mentiones above is possible.
