ABSTRACT:
Differentiation between grinding wheels which are dimensionally stable in use and which remove stock to specification tolerances and polishing wheels which are flexible and which primarily do not remove stock but which "fill the valleys with the hills" call for different development. This invention is directed to a polishing tool (wheel) comprising selected abrasive, filler and plastic elastomeric bond to produce a non-rigid solid tool (wheel) of minimum voids content, the cured elastomeric bond alone characterized by a Shore hardness of 45-55 but the completed tool face hardness is not in excess of about 96 "Shore A" hardness. The so limited polishing wheel is characterized by non-chattering, non-loading, aggressive and is yet non-smearing. It is arrived at by accurate volume control ratios of the components essentially present in the product.
