Abstract

Eine Schleifscheibe, und zwar insbesondere eine Trenn-Schleifscheibe, weist einen ringzylindrischen inneren Tragkörper (2) aus Metall und einen diesen umgebenden Schleifring (1) auf, die miteinander verbunden sind. Der Schleifring (1) steht beidseitig in Richtung der gemeinsamen Achse (4) über den Tragkörper (2) vor. Der Schleifring (1) kann vollständig abgeschliffen werden. Der Tragkörper (2) ist wiederverwendbar oder zumindest recycelbar.

Figure 00000001
A grinding wheel, in particular a cutting wheel, has a ring-cylindrical inner support body (2) made of metal and a slip ring (1) surrounding it, which are connected to one another. The slip ring (1) protrudes on both sides in the direction of the common axis (4) over the support body (2). The slip ring (1) can be completely ground off. The support body (2) is reusable or at least recyclable.
