Grinding wheel for cutting objects, in particular stones, bricks or similar, or wheel bodies or abrasive rings or lock-piece for such an abrasive ring

摘要

A ring wheel (3) fits coaxially on a wheel body (2), fastened by a removable fastening device. The ring wheel and the wheel body fit on-axis close to bearing surfaces opposite each other. The wheel ring supports a means (7) of grinding/cutting on its axial front side (6). A fastening device is formed by bayonet catches (4) that are distributed on a periphery and each operate between the wheel body and the ring wheel. An independent claim is also included for a locking dog for a grinding wheel for processing stones and bricks by cutting and removing metal.
