Electrical discharge machining removes material with controlled electrical sparks rather than a cutting edge. That makes it the right tool for square internal corners, deep narrow cavities, and hardened material that would punish a cutter. Union Enterprises runs die sinker EDM alongside its milling and turning work, so a part needing all three stays in one building.

When EDM Is the Right Call
- Square or sharp internal corners that a round cutter cannot produce
- Deep, narrow cavities where a tool would deflect or chatter
- Hardened material that has already been heat treated
- Delicate features where cutting forces would distort the part
Inspection
EDM features are verified on the same fully automatic three-axis OGP SmartScope used across the shop, and regulated jobs ship with first article inspection and material traceability attached.
