Method and device for the preparation of a fine machining tool and a fine machining tool

摘要

In a method for reprocessing a fine machining tool designed as a honing tool or finishing tool, which is designed for machining workpiece surfaces by means of geometrically indeterminate cutting edges, the fine machining tool has at least one cutting means carrier (552) which carries at least one cutting coating (565) which within a bond ( 556) has bonded cutting grains (557) and an abrasive working surface (551) for engagement with the workpiece surface. The method comprises the creation of the macro shape of the abrasive working surface (551) of the cutting coating (565) and a setting back of the bond (556) relative to the cutting grains (557) to produce a grain protrusion (K) on the working surface of the cutting coating. The method is characterized in that the setting back of the bond (556) with respect to the cutting grains (557) is carried out by means of selective laser ablation by irradiating the working surface (551) with pulsed laser radiation (LS) which is suitable for the material of the bond (556 ) between cutting grains (557) without removing the cutting grains to the same extent at the same time.
