摘要

The disk has a central bearing portion (30) for supporting the disk on a rotatable shaft and a grinding portion (31) which is adjoined radially outside at the bearing portion. A respective edge is provided with a profile for grinding the goods, where the profile is formed by multiple grooves (36) that are attached in the disk. Each groove is extended with a radial component which is greater than a rotational direction component of the groove, where each groove is formed in an arc-shaped manner. An independent claim is included for a grinding device with grinding rollers.
