ABSTRACT:
A metal polishing machine includes a rotary wire brush and a fixture for supporting a workpiece during the polishing operation. Also supported on the fixture are a plurality of ring mounted filler pins which extend into apertures in the workpiece and terminate at a surface of the workpiece to be polished. The pins prevent the brush from scouring or otherwise damaging the edges of the apertures during the polishing operation.
