    The notch polishing machine employs a plurality of polishing tapes which can be sequentially introduced into the notch of a wafer to polish both sides of the notch, i.e. the top and bottom surfaces. Each tape is pulled off a supply reel and passed into a mounting block sized to fit into the wafer notch. Each block is also mounted to be oscillated to effect a polishing action.The notch polishing machine employs a plurality of polishing tapes which can be sequentially introduced into the notch of a wafer to polish both sides of the notch, i.e. the top and bottom surfaces.
