Wire EDM (Wire Electro Discharge Machining)

Author: Kam Wire E.D.M. Technologies Inc. and Kam-Medical | | Categories: Wire EDM Cutting

Wire EDM (Wire Electro Discharge Machining, or WEDM) involves a continuously spooling conductive wire (the most widely used is brass). A power supply generates rapid electric pulses that create a discharge between the workpiece and electrode (the wire). The discharge causes the melting, and probably the vaporisation, of a minute piece of material, slowly eating into the work piece. Any electrical conductive material can be machined irrespective of hardness. The position of the wire with respect to the workpiece is controlled in the x and y planes usually by CNC. On some machines the wire can be tilted to create tapered parts. An advantage of this process is that no mechanical stresses are created in the workpiece because the wire does not make contact with it.
