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 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 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 . <EOS>
