OSR II

OSR II combines both, a calibrating machine and orbital scratch removal (OSR) units, in one machine. Irregularities of thickness from glued connections and remains of glue are removed by two or three contact rollers. Due to the succession of a steel contact roller and one or two rubber-coated contact rollers the scratches from the abrasives continuously become finer. The longitudinal sanding unit with a pressure segment belt makes them even finer. The optional RUT disk brush unit removes sharp edges from the work pieces. Finally two OSR units remove all visible sanding marks. In order to minimize vibrations in the calibration process produced by OSR units the contact rollers and the OSR units are mounted on separate supports.

When sanding frames and other work pieces with different grain directions sanding against the grain direction cannot be avoided. The generated scratch patterns are very evident, especially when dark stains are used. The Heesemann orbital sanding unit removes these scratches and leaves a clean surface with no visible scratches.
