Publication date: 20000927 Application No .: 98806639.4 Applicant: Method and apparatus for rounding cutting edges of a Gleason mill A method of processing a cutting edge of a cutting tool to reduce the degree of damage of the cutting edge during subsequent processing. A brush having a plurality of bristles is rotatable about a rotational axis and positioned relative to the cutting edge such that the brush axis is perpendicular to the cutting edge or about plus / minus 20 degrees with respect to the vertical. Subsequently, the brush is rotated and the knife and the rotating brush are brought into contact with each other with the abrasive involved. The cutting tool is preferably a cutting insert for cutting a toothed product such as a gear, wherein the cutting edge is formed by the intersection of the front surface of the cutting insert and the rear surface of the cutting insert. The rotating brush effectively polishes the front surface near the cutting edge and a portion behind the cutting edge while rounding the cutting edge.
