ABSTRACT:
A method of treating a cutting edge of a tool to reduce deterioration of the cutting edge during a subsequent machining operation. A brush having a plurality of bristles is rotated about an axis of rotation and positioned relative to the cutting edge whereby the brush axis is oriented perpendicular to the cutting edge or at an angle of up to about plus/minus 20 degrees with respect to the perpendicular orientation. The brush is then brought into contact with the cutting tool in the presence of an abrasive material. Preferably the cutting tool is a cutting blade for cutting toothed articles such as gears and the like wherein the cutting edge is formed by the intersection of a front face and a cutting side profile surface of the cutting blade. The rotating brush effectively polishes a portion of the front face and cutting side profile surface which is adjacent to the cutting edge while producing the rounding-off of the cutting edge.
