EMD is the name of Electrical Discharge Machining. It is quiet new machining technology especial high efficiency for the hard material for example tungsten carbide, high speed steel, and PCD tools. Especially for the tungsten carbide machining is the challenge since it is very hard and consume the electrode.
working in this field more than ten years. we dedicate to produce the tungsten copper electrode, chromium copper electrode, tungsten silver electrode for the EDM application.
copper tungsten wire electrode for tungsten carbide small hole machiningHOSOPM? copper tungsten wire size range: Dia. 0.5x175mm, Dia. 0.6x175mm, Dia. 0.7x175mm, Dia. 0.8x175mm, Dia. 0.9mmx175mm, Dia. 1.0x175mm
The qualify electrode for EDMing should has below properties:
