Abstract (en)
A circular-shaped abrasive device (10) configured to rotate around its own centre of rotation (1), and comprising a substantially flat front surface (2) with a plurality of openings. The openings comprise a series of through holes (4) which are positioned on the front surface (2) at areas surrounding the points identified by the intersection of a first set of geometric lines, formed of concentric circumferences (5) coplanar to the front surface (2) and having a centre of symmetry coinciding with the centre of rotation (1) of the abrasive device (10) and three second sets (7, 7', 7") of geometric lines, each formed of concentric ellipses (6), coplanar to the front surface (2).
