Abstract: The novel ferrule grinding machine of the present invention has a wire support assembly having a wire that stretches the length of the wire support on which ferrules are strung. The wire rests in a novel guide that aids in producing ferrules within tolerances. The machine also has a grinding wheel and regulating wheel whose speed and composition may be changed to determine the surface finish and concentricity of a ferrule. The regulating wheel infeed assembly controls the size of the ferrules via a computer and a step motor that control the position of the regulating wheel as it tilts on a pivot base to attain the correct size of ferrule. The wire support assembly is placed on a variable speed work traverse that carries the work between the grinding wheel and regulating wheel, while the ferrules are supported on a rest blade such that the ferrules are worked slightly above their center.
