Abstract
A novel method of polishing a workpiece surface comprises passing over the surface in elastically compressive abrasive contact therewith a mass of discrete, elastically deformable pieces each individually consisting of a matrix of elastomeric material containing finely divided abrasive particles substantially uniformly distributed at least along a surface region of the individual piece.
Claims16
A method of polishing a surface, comprising the steps of:
- preparing an amount of discrete, individually elastically deformable pieces, each of which individually consists of a matrix of elastomeric material containing finely divided abrasive particles distributed substantially uniformly throughout at least a surface region of the individual pieces;
- and
- passing said discrete, elastically deformable pieces in an aggregate compressively over said surface in frictional abrasive contact therewith while substantially maintaining a pressure-contacting and elastically deformable relationship between the individual pieces.
