摘要: A tool for deburring cut edges on workpieces has a pressure body in the form of a rolling body, by means of which, as relative longitudinal movement of rolling body and workpiece takes place, pressure can be applied to the burr on the relevant cut edge in the direction towards the workpiece while the rolling body rolls along the cut edge.A machine for deburring cut edges on workpieces is provided with a tool of the above-mentioned kind.In the course of a process for deburring cut edges on workpieces, a rolling body is moved along the relevant cut edge with a rolling motion. In that movement, pressure is applied by means of the rolling body to the burr on the cut edge in the direction towards the workpiece.
