EDM Machining for Cavities and Sharp Corners
Evidence strip: founded 2013 · about 40 CNC machines, as stated on the company website · ISO 13485 trust point, valid until 2028-04-15 (no certificate number or issuing body stated).
Electrical discharge machining, or EDM, cuts electrically conductive material with controlled sparks rather than a rotating cutter. It suits hardened steel, high-temperature alloys and shapes that a cutter cannot reach.
Send your EDM drawing for a process review — mark the cavity or corner that needs spark machining.
What this page covers
- Sinker EDM and electrical discharge machining for deep cavities and sharp internal corners
- Hardened steel and high-temperature alloys
- Tight-tolerance features and complex geometry
- Wire EDM as the companion process, covered on its own page
What to confirm before ordering
EDM is chosen when the material is too hard for conventional cutting, or when the geometry includes a deep cavity or a sharp internal corner. State the material and the feature that needs EDM when you send the drawing. Before ordering, confirm minimum order quantity and lead time for your drawings.
Drawing checklist
Send the drawing with units and scale stated, the material and grade, the critical dimensions and tolerances marked, and the finish required. State the quantity you need checked and the question the part must answer: fit, function or appearance. Uploaded files are used only for the quotation, and non-disclosure agreements are supported.
Quality checks
Parts are inspected with a coordinate measuring machine, a projector and height gauges, with quality control at each production stage, and a dimension report can be provided for a project on request.
