EDM machining knowledge
Precision solutions for challenging parts
EDM machining uses controlled electrical discharges to shape electrically conductive materials with accuracy and process flexibility. It is especially valuable when conventional cutting tools face hardened materials, intricate profiles, sharp internal corners, or narrow openings.
PartsMake reviews drawings, CAD data, material specifications, tolerances, critical dimensions, and surface requirements before production. This engineering-first approach helps identify manufacturing risks early and supports consistent results from prototype parts through repeat production.
When EDM is a strong fit
- 01 Complex contours and precision profiles that are difficult to mill.
- 02 Hardened conductive materials requiring non-contact cutting.
- 03 Deep holes, narrow slots, fine features, and sharp corners.
Process capability
EDM support from process planning to inspection
EDM can be coordinated with CNC machining, grinding, surface finishing, and inspection to create a complete manufacturing route for precision components.
Drawing review
Review geometry, tolerances, material, finish, and critical features before production begins.
Process selection
Match wire, sinker, or small-hole EDM with complementary machining processes where appropriate.
Controlled production
Manage setup, cutting strategy, secondary operations, and surface requirements with clear communication.
Quality verification
Verify dimensions and material-related requirements against drawings and project specifications.
