Capabilities Overview
Our EDM capabilities include:
- Wire EDM – for precision profiles and intricate geometries
- Sinker EDM – for internal cavities and complex forms
- Hole Drilling EDM – for starter holes and fine details
We routinely hold tolerances as tight as ±0.0001 inches and can machine hardened and exotic materials with ease. Our advanced EDM software enables us to generate intricate contours, sharp corners, and micro-features impossible with traditional tools. Every cut is clean, accurate, and repeatable.
Materials we handle include:
- Tool steels (A2, D2, H13)
- Titanium
- Inconel and other nickel alloys
- Stainless steel (304, 316, 17-4PH)
