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.

Machining Challenges

  • Recast layer must be removed for implants
  • Titanium forms tenacious oxide layer
  • Slower than steel due to lower conductivity
