Heesemann Orbital Scratch Removal OSR I
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.
The work pieces have to be prepared on a calibrating machine (e.g. a Heesemann MFA 10) to remove irregularities of thickness from glued connections and remains of glue. In this process the scratches of the abrasives continuously become finer. Heesemann OSR I removes sharp edges and finally all visible sanding marks.
