The process is based on the electro-erosion principle. Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the “tool” or “electrode,” while the other is called the workpiece-electrode, or “workpiece.” The process depends upon the tool and workpiece not making actual contact.

为了使高质量的微孔机posalux EDM机器有一个tilting head随着压力的变形allows to control the diameter of the hole, resulting in a run-out of the tool electrode. The electrode turns with a decentering, 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.
