Frequently Asked Questions

What is EDM machining and when is it used?

Electrical Discharge Machining (EDM) is a non-contact machining process that removes material using controlled electrical sparks rather than cutting tools. EDM is commonly used for complex geometries, fine features, and tight tolerances that are difficult to achieve using conventional machining methods.

What types of EDM processes does Staub provide?

Staub offers both wire EDM and sinker EDM capabilities to support a wide range of precision applications. These technologies allow accurate machining of intricate profiles, internal features, sharp corners, and detailed cavities across conductive materials.

Why is EDM ideal for hard or heat-treated materials?

Because EDM does not apply mechanical cutting force, it can machine hardened metals and specialty alloys without tool pressure or deformation. This makes EDM well-suited for aerospace, medical, defense, and high-performance industrial components requiring dimensional stability.

Can EDM machining improve part accuracy and surface quality?

Yes. EDM produces burr-free surfaces and extremely precise features while minimizing heat-affected distortion. This reduces secondary finishing requirements and supports consistent repeatability across production runs.

How does EDM machining integrate with Staub’s production manufacturing approach?

EDM machining operates within Staub’s broader automated precision machining environment, integrating with CNC machining, inspection, finishing, and assembly workflows to deliver production-ready components with reliable repeatability.
