Wire EDM — for features no end mill can reach.
Wire EDM cuts hardened steel, carbide, and exotic alloys with no tool pressure and no heat-affected zone of consequence. Square internal corners. Tight kerf. Repeatable across full job. Aerospace and tooling work.
For geometry you can't mill and material you can't deflect.
Wire EDM uses an electrically charged wire (typically .010" brass) to erode material. No mechanical force on the part. Heat input is minimal and surface-localized — critical for hardened or pre-tempered material that machining would distort.
Hard materials
Tool steel after heat treat (52–65 HRC), carbide, Inconel, titanium. Cut the finished hardness — no second tempering cycle to chase tolerance.
Square internal corners
Wire radius drives inside-corner geometry. .010" wire produces a .005" corner radius. Far tighter than end mills can reach without prohibitive cycle times.
No-pressure machining
Thin webs, fragile features, delicate fixtures — wire EDM doesn't deflect the part. Ideal for stator/rotor laminations, surgical instruments, optics housings.

Sinker EDM
For deep cavities, blind holes, and internal sharp corners wire can't reach.
