In a machine for processing the edges and outer surfaces of flat workpieces, including a machine frame with a workpiece support surface 12 and at least one dressing head 14 with a work tool carrier, which work tool carrier is rotatably supported on the machine frame for rotation about a first axis perpendicular to the workpiece support surface 12 and is driven by a drive, and which work tool carrier carries at least two work tools 32 rotatably supported eccentrically to the first axis on the work tool carrier each for rotation about a second axis perpendicular to the workpiece support surface 12 , and each of which tools is connected with a planet gear 44 which stands in meshing drive engagement with a sun gear 26 coaxial to the first axis so that each circulating work tool carrier defines an effective circle 46 of its work tools 32 , with at least two dressing heads 14 being so arranged next to one another that the effective circles 46 of their work tools 32 overlap, with the movement of the work tool carriers of neighboring dressing heads 14 being so controlled that the work tools 42 arranged on their work tool carriers are displaced from one another in the circulating direction.
