| A method of treatment and processing of tools for machining of workpieces by cutting is described, in particular milling tools. These tools are made up of a high-strength steel, carbide or ceramic, and are provided with at least one cutting flank and a flute, which cutting flank is provided with a cutting edge on the cutting side. In a coating installation, the tool is provided with a first coating which is wear-resistant against abrasion. Afterwards a bevel is ground on each of the cutting edges. A second coating, which is resistant to crater wear, is applied to the ground bevel in a coating installation. Tools are thereby obtained that are characterized by high abrasion resistance and high resistance to wear and tear, in particular during machining of difficult materials at high cutting speed. | ||||||

Es wird ein Verfahren zur Behandlung und Bearbeitung von Werkzeugen zur spanabhebenden Bearbeitung von Werkstücken, insbesondere Fräswerkzeuge, beschrieben. Diese Werkzeuge bestehen aus einem hochfesten Stahl, Hartmetall oder Keramik und sind mit mindestens einer Schneidflanke und einer Spannut versehen, welche Schneidflanke auf der Schneidseite mit einer Schneidkante ausgestattet ist. Das Werkzeug wird in einer Beschichtungsanlage mit einer ersten Schicht versehen, welche verschleissfest ist gegen Abrasion. Danach wird an den Schneidkanten jeweils eine Fase angeschliffen. Auf die angeschliffene Fase wird in einer Beschichtungsanlage eine zweite Schicht aufgebracht, die widerstandsfähig ist gegen Kolkverschleiss. Dadurch werden Werkzeuge erhalten, die sich durch eine grosse Abrasionsbeständigkeit und eine gute Verschleissfestigkeit auszeichnen, insbesondere beim Bearbeiten von schwierigen Materialien mit hoher Schnittgeschwindigkeit. |
