The apparatus has a brush (3) rotatable on a housing (1) about a brush axis. The brush axis has bristles (5) extending generally radially of the axis. Tips are provided for defining on rotation of the brush a circular orbit centered on the axis. The tips are engageable at a location with a workpiece surface. A blocking element is positioned radially inside the orbit immediately upstream from the location in a normal rotation direction of the brush. A drive unit is provided for rotating the brush in a working direction about the axis relative to the housing. An independent claim is also included for a method of abrading a workpiece. |
