Hohlkehlgeometrie an rotierendem Diamant-Schneidwerkzeug

摘要

A diamond or cubic boron nitride cutting tool has at least a pair of grooves in the body of the tool. The grooves contain polycrystalline diamond or cubic boron nitride prior to formation of concave flutes next to the grooves. The grooves are angled to form positive or negative cutter rake angles, whichever is desired. The adjacent concave flutes subsequently formed in the body of the cutting tool each have an edge parallel with an edge of the polycrystalline material in the grooves. Sharpening of the diamond then results in very little removal of the diamond material, thus assuring the integrity of the tool.
