发明名称 Method of and device for conducting machining current to a wire-electrode tool in a wire-cutting electroerosion machine
摘要 A device for conducting a machining current to a traveling wire-electrode tool in a wire-cutting electroerosion machine comprises a rotary brush block (e.g. of cylindrical shape) having a planar current-conducting surface disposed in a wire-travel path for making sliding electrical contact with the moving wire-electrode tool. A motor rotates the brush block about the rotary axis thereof to rotationally move the current-conducting surface in tangential sliding electrical contact with the moving wire-electrode tool. A scraper is provided downstream of the workpiece machining zone and upstream of the brush block to remove abrasive particles and machining chips and other products (e.g. tar) adherent on the wire tool fed from the machining zone, thus to prevent them from being carried onto the brush surface.
