Wire EDM
Wire EDM cuts conductive material with a continuous wire electrode and a controlled spark, so hardness is irrelevant and there is no cutting force. That makes it the only realistic route for hardened inserts, sharp internal corners, thin webs and features that a milling cutter simply cannot reach.

Preguntas frecuentes
What are the limitations of wire EDM?
It only cuts electrically conductive materials and it is slower than milling, so we use it where hardness or geometry demand it and remove bulk material by milling first.
Can you cut a part that is already heat treated?
Yes — that is its main advantage. Parts are usually hardened first and then wire cut to final dimensions so no distortion occurs afterwards.
Does EDM leave a recast layer?
Conventional cutting leaves a thin recast layer which we remove with multi-pass skim cuts. For fatigue or medical parts we schedule a final low-energy pass and verify with cross-section analysis.
