Abstract
For machining the tooth flanks of a hardened workpiece having pre-formed teeth two cutting blades or plates are secured to a cutting blade or plate holder. The cutting blades or plates are provided with a base member or backing formed of a hard metal and a cover layer sintered thereon which is formed of cubic boron nitride. Each cutting blade forms a cutting surface and a clearance surface. Each individual cutting blade or plate is arranged at the cutting blade or plate holder in relation to the direction of the intended cutting movement such that the surface of the cover layer forms the clearance surface and an end face or surface of the cover layer is located in the cutting surface. Consequently, there is achieved the result that the cutting surface can be reground in the same manner as tools which, for example, are made of hardened steel and which are not provided with a cover layer.
