Abstract
Cubic boron nitride tooling, e.g. for woodworking, is fabricated with the same geometries and machinery as is used for fabricating conventional carbide tooling.
Claims11
A cutting tool for woodworking-type applications, comprising:
- a carrier body;
- and
- one or more cutting tips comprising cubic boron nitride, and being attached to said carrier body;
- wherein said cutting tips, as attached to said carrier body, define positive respective hook angles of 5 degrees or greater.
1 more element
A method of fabricating a woodworking tool, comprising the actions of:
- attaching one or more cutting tips, comprising cubic boron nitride, to a carrier body;
- and
- grinding said cutting tips using machinery, geometries and tooling suitable for grinding tungsten carbide cutting tips, but with a slower feed rate.
