Abstract (en)
[origin: EP2228173A2] The device (1) has compressed air guiding devices (15, 16, 18) arranged between a compression air drive (4) and a polishing pad (2) and/or a sharpening unit. The guiding devices guide drive compression air (8) of the compression air drive from an outlet side of the guiding devices to the polishing pad and/or to the sharpening unit. The drive compression air of the compression air drive is conveyed from a middle area of a lower surface (3) of the polishing pad and/or the sharpening unit to a circumferential edge (19) of the polishing pad and/or the sharpening unit by air ducts (20).
