[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.
