PURPOSE:To enchance the speed of processing and the accuracy of the processed surface of a workpiece, by providing a polishing agent at perscribed intervals on the surface of a wire electrode for electric discharge processing to polish the processed surface during the feed to the wire electrode. CONSTITUTION:A polishing agent 6, which is manufactured by sintering and bonding grains of a very hard substance such as diamond and ceramic, is annularly provided at prescribed intervals on the cylindrical surface of a wire electrode 1. To provide the polishing agent 6, the grains of green Carborundum, ceramic, diamond or the like are mixed with phenol, epoxy, feldspar and so forth and the mixture is applied to the electrode 1 and sintered. The surface of a workpiece 2 processed by the electrode 1 can be set at a roughness of 1mum by optionally determining the quality of the polishing agent 1. The processed surface of the workpiece 2 is polished by the agent 1 during the feed of the electrode 1. The speed of the processing and the accuracy of the processed surface can thus be heightened. |
