A rack (12,14) for burnishing toothed gears (16) in cooperation with another like rack so as to provide accentuated axial crowns on the burnished teeth is disclosed as having a unitary body (42) of an elongated shape with leading and trailing ends (44,46) and a toothed forming face (48) extending between the ends. The toothed forming face (48) includes a leading section a of teeth that extend parallel to a mounting surface (54) of the rack body and at least one section of inclined teeth (50) preferably embodied by an intermediate section b and a trailing section c. A fixture (60) for grinding the inclined tooth sections b and c on a pair of cooperable racks (12,14) includes a pair of inclined support surfaces (66,68) and a clamp (70) for clamping the rack bodies during the inclined tooth grinding.
