Abstract
A method for grinding and/or polishing a defect in the surface coating of a workpiece involves holding a grinding or polishing disc held on a tool and guiding the disc with pressure over the defect with orbital, rotating and/or vibrating movements. The tool fitted with the grinding or polishing disc is moved over the defect automatically and in a computer-controlled manner based on a stored program, wherein the grinding or polishing disc is first guided along a concentrically inner grinding path relative to the defect and then without interruption is guided along a spiral grinding path to an outer concentric grinding path.
