Abstract (en)
[origin: EP0054368A2] A smoothing pad having a working surface (1, 33) formed with a plurality of depressions (6, 12, 30) for indicating wear of the working surface of the pad. Each depression preferably diverges towards the working surface of the pad so that the dimension of each depression in a direction transverse to its depth will diminish as the working surface wears. Each depression constitutes a reservoir for an abrasive slurry used with the pad and a gradual transition is preferably defined between each depression (30) and the working surface whereby, in use, the abrasive slurry (S sec ) will be encouraged to flow from each depression on to the working surface.
