Abstract:
PCT No. PCT/SE91/00016 Sec. 371 Date Aug. 13, 1992 Sec. 102(e) Date Aug. 13, 1992 PCT Filed Jan. 10, 1991 PCT Pub. No. WO91/10532 PCT Pub. Date Jul. 25, 1991.The invention relates to a process and a device for dressing truncated conical tips of electrodes 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 on its end surface. In a first machining step, the electrode tip is inserted into a cavity in a first tool for machining the lateral surface or the end surface 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 for machining the end surface of the lateral surface 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 for machining the truncated conical lateral surface and a second motor driven, rotary tool form machining the end surface of the electrode tip. The first tool is provided with an abutment for the end surface of the electrode tip, and the second tool is provided with an abutment for the lateral surface of the electrode tip.
