Abstract

L'invention concerne un outil de séparation (1) en forme de disque, un procédé de séparation radiale pour l'usinage de pièces allongées axialement, un dispositif de séparation ainsi qu'une utilisation d'un outil de séparation en forme de disque. Un outil de séparation en forme de disque selon l'invention présente une flexibilité définie et un impact défini. Lors d'un processus de séparation radiale selon l'invention, une déviation latérale de l'outil rotatif (1) axialement fixe amène celui-ci dans un contact actif axial avec la ou les surfaces de ponçage et de polissage (6, 20, 21, 22), montées latéralement, sur la pièce à usiner. Dans un dispositif de séparation selon l'invention, l'outil de séparation (1) est mobile exclusivement radialement pour l'usinage de la pièce. Une utilisation selon l'invention d'un outil (1) en forme de disque sert à une préparation d'échantillon et à une analyse de surface ultérieure sur une pièce mise à la longueur.
