Breakthrough detection

Breakthrough is detected! Revolutionary new development by Heun company in the field of EDM drilling.

After a development phase of several years, Heun successfully generated a system to detect the breakthrough of the electrode, independent from the electrode wear and to initiate respective actions via the control system of the machine, to influence depth and eroding characteristics during the further drilling process.

electrode stabilisation for small electrodes

Because of the new electrode stabilisation the desired process stabilisation is achieved easily and effectively. The special characteristic here is: the electrode is always kept in the centre by the lunette. Deflection of electrode is therefore effectively reduced.
