ABSTRACT:
The flapped grinding disk comprises a disk- or plate-shaped support and grinding flaps which overlap each other on the support in the manner of shingles and which are secured in an adhesive bed. Apertures are cut away on the periphery of the flapped grinding disk, the apertures have approximately the form of a part of an annulus with a front edge and an edge at the rear in the direction of rotation of the grinding disk and at least the edge of the apertures that is at the rear in the direction of rotation of the grinding disk runs approximately radially. The grinding flap adjoining the rear edge of the aperture can form a ramp. The front edge of the apertures can also run approximately radially. The radial depth of the apertures can be equal to the radial extent of the grinding flaps, so that no remnants of grinding flaps remain at the inner edge of the apertures.
