Abstract

A removable polishing pad for a polishing machine that provides a rotatable polishing platen that supports the polishing pad. The pad assembly of this invention includes a circular polishing pad that is adhesively attached to one surface of a circular carrier disc. The polishing pad has a diameter less than that of the carrier disc such that the exposed circumferential edge of the disc is equipped to provide means for removably securing the disc to the platen for rotation therewith.
