Abstract (en)

[origin: EP0494435A1] The object of the invention is to disclose an abrasive of the type in question, which, while avoiding the limitations which the abrasives of the prior art are subject to, calls for a lower proportion of abrasive grains and thus low costs but nonetheless ensures a performance comparable with conventional abrasives. This object is achieved in the abrasive according to the preamble of Claim 1 by these additives being present roughly in the size of the abrasive grain and having less hardness than the abrasive grain.
