Patent Abstract

The invention relates to a method for processing a cutting edge of a machining or cutting tool, wherein a liquid-abrasive jet is directed onto the cutting edge via a jet nozzle, and a device for carrying out the method. The object of the invention is to provide a method for preparing a cutting edge of a machining or cutting tool, in which a better approximation to a target geometry to be produced is achieved with the generated geometric edge shape of the cutting edge. This object is achieved in that a liquid-abrasive suspension is first formed in a high-pressure mixing chamber (8) from a liquid carrier medium and abrasive particles (9), and this liquid-abrasive suspension is subsequently guided in a flow system to the jet nozzle (11) and accelerated at the latter in the direction of the cutting edge (1). Furthermore, a device for carrying out the method is proposed.
