µ-EDM
Based on the electro erosion principle, the integrated SARIX µ-EDM
technology allows machining with high quality and efficiency, meeting the
needs of mass production scenarios.

µ-EDM = Micro Electrical Discharge Machining

Electrode guiding system
The integrated advanced electrode guiding system precisely feeds the
smallest electrode available on the market, down to 30 µm.
