Wire EDM for Titanium Grade 5 (Ti-6Al-4V)
Wire EDM is an excellent process for titanium Grade 5, bypassing all the conventional machining challenges. It cuts titanium at the same speed regardless of its hardness and eliminates tool wear entirely.
Recommended Machining Parameters
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm |
| Surface Finish | Ra 0.2-0.8 μm |
| Cutting Speed | Moderate — similar to stainless |
| Feed Rate | Auto-tuned by EDM controller |
| Tooling Recommendations | Brass wire 0.20-0.25mm. Dedicated EDM settings for titanium. |
