Abstract
An exchangeable abrasive mechanism or disc for use on abrasive-mechanism carriers having suction holes includes a plurality of through openings that each have a centroid. The through openings are differentiated into three groups that differ in the radial disposition of the centroids. A first group comprises at least one, but not more than four, through openings of a first cross section. At least two of the through openings of the first group are disposed on a first circumcircle diameter that is substantially identical to one of the hole-circle diameters such that, when the abrasive mechanism is correctly disposed on an abrasive-mechanism carrier, they are in direct alignment with and can overlap, two corresponding suction holes. A second group of through openings of a second, preferably smaller, cross section, comprises at least four through openings that are disposed on a second circumcircle diameter that differs from the first circumcircle diameter.
