ABSTRACT:
Apparatus for abrading the surface of a workpiece in a manner level with a selected reference plane, e.g. a horizontal reference plane. The apparatus includes a wheeled carriage to which is connected an elongated boom. Extending downward from the end of the boom is an abrading element which is mounted for rotation in a selected reference plane which is preferably horizontal, and which is prevented form tilting in a longitudinal or transverse direction relative to the boom. The boom is connected to the carriage by an adjusting mechanism which allows the carriage end of the boom to be raised or lowered so that the surface of the abrading element may be brought to a position which corresponds to the selected reference plane.
