A practical guide to when CNC milling is the right starting point and when EDM machining may be needed for fine detail, hard material, cavities, or difficult internal geometry.
Milling is often the right process for pockets, slots, flats, profiles, drilled features, and accessible geometry. It can be efficient, accurate, and flexible for many industrial components and tooling details.
When the feature is accessible to a cutter and the material supports conventional machining, milling is usually a strong starting point.
EDM becomes useful when the part requires sharp internal geometry, fine cavity details, hard materials, deep details, or shapes that are difficult to reach with conventional cutting tools.
Many projects use milling to prepare the component and EDM to finish selected features.
The best process depends on geometry, material, finish, tolerance, quantity, and lead time. Send the drawing or model and identify the features that are most critical.
Superior can recommend a process path that may include milling, EDM, grinding, finishing, inspection, or marking.
FAQ
Yes. Send the drawing, photo, material, quantity, and desired result. Superior can recommend a starting direction after review.
