Copper Electrical Discharge Machining
My feature is too fine, too deep or too hard to mill. Who can spark it out, and are they NADCAP accredited for it?
What it is
Removing material by controlled electrical discharge between an electrode and the workpiece, cutting geometry that tooling cannot reach and materials too hard to mill.

KLH Industries ReportedNADCAP Nonconventional Machining
Wire EDM to +/-0.0001 in, sinker EDM to +/-0.0002 in and small hole EDM drilling to +/-0.001 in. KLH states its EDM covers 'All electrically conductive materials' rather than naming metals individually, so this is recorded from that category statement and held at MEDIUM. The page does not qualify the capability per material, and the NADCAP EDM accreditation scope is not broken out by material either. Wire EDM is stated to cut without inducing stress into the material, which is the reason it is chosen for thin or brittle parts.
