Abstract

The present invention relates to a grinding device (1) comprising a plurality of cylindrical abrasive bodies (4, 5, 8) each having a cylindrical support core (4b, 5b, 8b) and an outer layer (4c, 5c, 8c) for material removal, which is made of abrasive material. The grinding device further comprises a plurality of intermediate elements (6) alternated with the cylindrical abrasive bodies (4, 5, 8) to axially space the circumferential abrasive surfaces (4a, 5a, 8a) of said bodies apart. The intermediate elements (6) have a smaller diameter than the maximum diameter of the cylindrica- support core (4b, 5b, 8b) of the cylindrical abrasive bodies (4, 5, 8) so as to define a series of circumferential cooling grooves (6a) enabling a cooling fluid to act on the overheated parts to a greater extent.
