Head 2: OSR Head – Orbital Sanding Unit
The patented orbital sanding unit combines a variable speed single orbit rotation with a variable
speed lamella belt that has a serpentine movement and runs inside the abrasive belt to break up
the orbit scratch, providing a truly random scratch. The wide belt floats on an air cushion to
allow for an easy movement of the abrasive in the orbit rotation without providing significant
vibration. The orbital sanding unit uses traditional wide belts which advance automatically with
an automatic belt advancing function for low abrasive belt cost and long service life prior to a
belt change.
