Electrical Discharge Machining - EDM Technology

The process is based on the electro-erosion principle. Material is removed from the workpiece by a series of rapidly recurring current discharges between electrode and anode, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the “electrode”, while the other is called the anode, or “workpiece.”

In order to machine high quality micro holes the Posalux EDM machines have a tilting head with deformation by pressure that allows to control the diameter and the shape of the hole, resulting in a run-out of the electrode. The electrode turns on a decentered axis, giving two different gaps, one where sparks erode the material and another, bigger one, allowing a better flushing of eroded materials. In combination with CNC driven axis and a high-speed interface to communicate with the micro EDM generator, perfect micro holes are the result.
