ABSTRACT:
A burnishing machine and method employing a pair of oppositely disposed burnishing gears. The invention involves the use of two syncronously driven gears which operatively engage teeth on opposite sides of a spline or a gear. In one embodiment, for generally elongated articles, the axes of the workpiece and the gears are generally horizontal. In another embodiment for generally flat articles, the axes of the workpiece and the gears are generally vertical. In both embodiments the gears are rotated at an angular velocity sufficient to hold the workpiece translationally stationary. In the preferred embodiment the burnishing gears have different pressure angles and therefore burnish different portions of the workpiece tooth profile.
