Title (EN) GRINDING AND/OR CUTTING TOOL AND METHOD FOR GRINDING AND/OR CUTTING
(FR) OUTIL DE RECTIFICATION ET/OU DE SÉPARATION ET PROCÉDÉ DE RECTIFICATION ET/OU DE SÉPARATION
(DE) SCHLEIF- UND/ODER TRENNWERKZEUG UND VERFAHREN ZUM SCHLEIFEN UND/ODER TRENNEN
Abstract:
(EN) The invention relates to a grinding and/or cutting tool which has at least one surface region for a lateral grinding process and a surface region for a circumferential grinding process and/or a cutting process. According to the invention, the surface regions (2, 3, 4) have different removal properties. Advantageously, the material properties of the surface regions (2, 3, 4) differ in that the surface regions have different abrasive materials, grinding particle shapes, particle scattering patterns, particle sizes, degrees of hardness, structures, and/or binders. In one embodiment of the invention, the grinding and/or cutting tool (1) has two of the surface regions (2, 4) for a lateral grinding process, and the two surface regions (2, 4) for a lateral grinding process are arranged at a distance from one another, wherein the surface region (3) for a circumferential grinding process or for a cutting process is arranged preferably between the two surface regions (2, 4) for a lateral grinding process.
(FR) L’invention concerne un outil de rectification et/ou de séparation, qui comprend au moins une zone de surface à rectifier par le côté et une zone de surface à rectifier par la périphérie et/ou à séparer. Selon l'invention, les zones de surface (2, 3, 4) présentent des propriétés d’enlèvement différentes les unes des autres. Avantageusement, les zones de surface (2, 3, 4) se distinguent dans leurs propriétés de surface par le fait qu’elles présentent des substances abrasives, des formes de grains abrasifs, des dispersions de grains, des granulations, des duretés, des textures et/ou des liants différents les uns des autres. Dans un mode de réalisation de l’invention, l’outil de rectification et/ou de séparation (1) comporte deux des zones de surface (2, 4) à rectifier par le côté et les deux zones de surface (2, 4) à rectifier par le côté sont agencées à distance l’une de l’autre, la zone de surface (3) à rectifier par la périphérie ou à séparer étant agencée de préférence entre les deux zones de surface (2, 4) à rectifier par le côté.
(DE) Die Erfindung betrifft ein Schleif- und/oder Trennwerkzeug, das zumindest einen Oberflächenbereich zum Seitenschleifen und einen Oberflächenbereich zum Umfangs-schleifen oder/und Trennen aufweist. Erfindungsgemäß weisen die Oberflächenbereiche (2,3,4) voneinander unterschiedliche Abtragseigenschaften auf. Zweckmäßigerweise unterscheiden sich die Oberflächenbereiche (2,3,4) in ihren Materialeigenschaften dadurch, dass sie unterschiedliche Abrasivstoffe, Schleifkornformen, Kornstreuungen, Körnungen, Härten, Gefüge und/oder Bindemittel voneinander aufweisen. In einer Ausgestaltung der Erfindung weist das Schleif- und/oder Trennwerkzeug (1) zwei der Oberflächenbereiche (2,4) zum Seitenschleifen aufweist und die beiden Oberflächenbereiche (2,4) zum Seitenschleifen im Abstand voneinander angeordnet sind, wobei der Oberflächenbereich (3) zum Umfangsschleifen oder Trennen vorzugsweise zwischen den beiden Oberflächenbereichen (2,4) zum Seitenschleifen angeordnet ist.
