ABSTRACT:
A method for finishing the full radial surface of a face type commutator includes relatively rotating the commutator on its axis with respect to a cutter to form a finish on the commutator face which includes radially inwardly cross hatch segments which become progressively open toward the outer periphery of the commutator and which end in a series of generally radially directed single line segments at the radially outer portion of each of the conductor segments of the commutator so as to dress slot edged during cutting to prevent formation of slot burrs; thereafter brushing the commutator face to remove loose chips therefrom followed by finishing the surface to remove irregularities therefrom and to form surface roughness thereon for brush run-in. The apparatus includes a rotary dial having a plurality of rotatable workholders thereon each carrying one commutator and wherein a cutter spindle, rotary brush and an abrasive wheel spindle are located at circumferentially spaced points around the periphery of the rotary dial to perform the functions of the method.
