Patent ID: 6926583

Claim:
A grinding wheel for removing a coating material from coated surfaces of constructional components, the grinding wheel comprising a circular grinding region ( 1 ) having a plane coincident with the surface thereof; a plurality. of through-openings ( 3 ) formed in the grinding region ( 1 ); a central mounting region ( 2 ) coaxial with the grinding region ( 1 ); and a plurality of cutting bodies ( 4 ) having a rectangular base surface, projecting from the grinding region ( 1 ), and spaced from a center of the mounting region ( 2 ) by different radial distances, each cutting body ( 4 ) being perpendicularly disposed to the plane of the grinding wheel and the cutting face of said cutting bodies each inclined to form an effective. cutting angle (A) therewith and having a longitudinal side ( 5 ) adjacent to the center of the mounting region ( 2 ) and a wide side ( 6 ) remote from the center of the mounting region ( 2 ), the adjacent longitudinal side ( 5 ) and the remote wide side ( 6 ) forming together a cutting edge (K) for wedge-cutting of the coated material, and the adjacent longitudinal side ( 5 ) extending at an angle (B) of from 35° to 55° to a radial line (R) extending from the center of the mounting region ( 2 ) and passing tangentially to the edge (K).
