摘要： A stamped or fine-blanked, workpiece is inserted in an embossing device, and the burr created on the workpiece during stamping or fine blanking is rounded by way of a die of the embossing device and the height of the rollover created during stamping or fine blanking is decreased using the same stroke of the embossing device by way of which the burr rounding is carried out.
