摘要：The invention relates to a process and a device for dressing truncated conic al tips of electrodes (1, 2) in a spot welding gun, press or the like. According to the process, each electrode tip is dressed both on its truncated conical lateral surface (1a, 2b) and on its end surface (1b, 2b). In a first machining step, the electrode tip is inserted into a cavity in a first tool (20, 21) for machining the lateral surface (1a, 2a) or the end surface (1b, 2b) until the other of these two surfaces comes into contact with an abutment, whereafter the electrode tip in a second machining step is inserted into a cavity in a second tool (21, 20) for machining the end surface (1b, 2b) or the lateral surface (1a, 2a) until the surface which has been machined in the first machining steps comes into contact with an abutment. The device according to the invention comprises a motor driven, rotary tool (20) for machining the truncated conical lateral surface (1a, 2a) and a second motor driven, rotary tool (21) for machining the end surface (1b, 2b) of the electrode tip. The first tool (20) is provided with an abutment for the end surface (1b, 2b) of the electrode tip, and the second tool (21) is provided with an abutment for the lateral surface (1a, 2a) of the electrode tip.
