Combined grinding and brushing apparatus which defines a rotation axis about which the combined grinding and brushing apparatus is rotated while being used, wherein the combined grinding and brushing apparatus has a base member which is configured in a substantially disc-like, annular, plate-like or bell-like manner and which extends in a circumferential direction around the rotation axis, wherein the base member has in a first circular-ring-like region a grinding coating which is arranged directly on the base member and which extends in the circumferential direction at least partially around the rotation axis, and wherein the base member has in a second circular-ring-like region which is spaced apart from the first region or which is adjacent thereto a brush which is arranged directly on the base member, wherein the brush has a plurality of brush elements which are secured with a first end to the base member and which with a free end which is opposite the first end protrude from the base member in such a manner that the free ends during brushing of a workpiece come into contact with the surface, which is intended to be brushed, of the workpiece, and the brush at least partially extends around the rotation axis in the circumferential direction, wherein the second circular-ring-like region is arranged on a covering face, which is orientated transversely relative to the first, circular-ring-like region on the inner or outer edge of the base member or is offset relative to the first, circular-ring-like region in an axial direction along the rotation axis, characterized in that the brush has a plurality of part-brushes (34a, 34b) which are arranged in different segments, which are spaced apart from each other in the circumferential direction, in the second region on the combined grinding and brushing apparatus. wherein the base member has in a first circular-ring-like region a grinding coating which is arranged directly on the base member and which extends in the circumferential direction at least partially around the rotation axis, and wherein the base member has in a second circular-ring-like region which is spaced apart from the first region or which is adjacent thereto a brush which is arranged directly on the base member, wherein the brush has a plurality of brush elements which are secured with a first end to the base member and which with a free end which is opposite the first end protrude from the base member in such a manner that the free ends during brushing of a workpiece come into contact with the surface, which is intended to be brushed, of the workpiece, and the brush at least partially extends around the rotation axis in the circumferential direction, wherein the second circular-ring-like region is arranged on a covering face, which is orientated transversely relative to the first, circular-ring-like region on the inner or outer edge of the base member or is offset relative to the first, circular-ring-like region in an axial direction along the rotation axis, characterized in that the brush has a plurality of part-brushes (34a, 34b) which are arranged in different segments, which are spaced apart from each other in the circumferential direction, in the second region on the combined grinding and brushing apparatus.
