ABSTRACT:
The present application provides a finishing chamber lining, particularly suited for use in an industrial type finishing machine, comprising a compressible elastomeric substrate having a particulate, insoluble, abrasive material uniformly distributed therethrough and having a working or outer surface, the abrasive material having a particle size between one (1) and 100 microns and a hardness, as measured on the Mohs Hardness Scale, of at least one (1), the abrasive material being insoluble in the elastomeric substrate and in reactants and solvents employed in producing the same, the working surface comprising an outermost abrasive-interspersed, gripping surface which is adapted to be self-regenerating upon erosion in use. The finishing chamber lining increases the work action within the finishing chamber and minimizes inactivity, depression, or dead spots within the finishing chamber when in use with loose finishing media and workpieces to be finished therein. Finishing chambers lined with the same, finishing machines comprising such lined finishing chambers, and method of making and using, are also provided.
