EDM Machining
Custom CNC EDM Machining Services
Precision EDM machining that produces complex cavities, fine details and tight tolerances in hardened materials for molds, dies and precision components.
Capabilities
EDM Machining Capabilities
We combine sinker, wire and hole EDM to machine complex geometries and fine details in hardened materials.
Sinker EDM
Machines complex cavities and blind features with high accuracy.
Wire EDM
Cuts precise contours and tight tolerances through hardened material.
Hole EDM
Produces small, accurate starter holes and cooling channels.
Surface Finish Control
Controlled surface texture that meets your cosmetic and functional requirements.
Process selector
Choose the Right EDM Method
Select an EDM method to see how it fits your geometry, material and tolerance requirements.

FAQ
EDM Machining Questions
What is the difference between sinker and wire EDM?
Sinker EDM machines complex cavities and blind features with an electrode, while wire EDM cuts precise contours through the material. We recommend the method that best fits your geometry and tolerance.
What surface finish can you achieve?
We control EDM surface finish through machining parameters to match your drawing and functional requirements.
Which materials can you machine with EDM?
EDM machines electrically conductive materials including hardened steel, tool steel and other alloys.
What tolerances can you hold?
We hold tight tolerances on EDM features to the specification on your drawing. Share your tolerance and we will confirm the achievable result.
Can you machine prototype parts with EDM?
Yes. We machine prototype and low-volume parts so you can validate geometry and finish before production.
