EDM wire cutting and sinking

EDM expertise for tight tolerances and demanding materials

Calip Group masters electrical discharge machining (EDM) processes, including wire cutting and sinking, for the production of complex mechanical parts in hard, treated or conductive materials.

These precision technologies allow extremely tight dimensional tolerances while ensuring excellent surface finish — even for intricate internal geometries. Essential for high-requirement applications, EDM is widely used in defense, aerospace, medical and tooling industries.

Wire cutting : high-precision machining for complex shapes

Wire electrical discharge machining (EDM wire cutting) is a high-precision process perfectly suited to complex technical parts.

Using a very fine conductive wire, precisely guided by CNC, this non-contact cutting method allows for:

closed contours
fine geometries
thin walls
sharp corners (wire diameter down to 0.15 mm)

It ensures exceptional dimensional stability and smooth finishes.

Wire cutting is widely used for tooling as well as in high-demand sectors such as aerospace, defense, medical and robotics, where precision, dimensional integrity and surface quality are critical.

EDM sinking: machining complex internal cavities

EDM sinking is a high-precision process that uses custom-designed electrodes to shape complex internal features.

This non-contact technology enables:

technical impressions
narrow cavities
deep form bottoms
inaccessible geometries for conventional cutting tools

Sinking is compatible with a wide range of conductive materials, including hardened steels, stainless steel, titanium and carbides. It is especially suitable for manufacturing moulds, cutting tools, forming electrodes or high-precision mechanical components.

Integrated into our production chain, this process ensures optimal repeatability, consistent quality and reduced reworking — for reliable, well-controlled production.
