Screw thread electrode and method processing screwed hole in die using same

The invention discloses a screw thread electrode and a method processing screwed hole in a die using the same. The screw thread electrode comprises a base, the base is connected with a screw rod, the screw rod is provided with a plurality of segments of threads, vacancy segments are disposed between adjacent threads, and three segments of threads which are a first segment of thread, a second segment of thread and a third segment of thread are disposed. The method processing a thread die comprises rough machining, finely machining a screwed hole in a die respectively using the plurality of segments of threads, and truing the screwed hole, if necessary, the precision of a processed thread is effectively ensured.
