Polishing of Titanium Components
Complete guide to mechanical polishing of titanium alloys. Process parameters, grit sequences, and achievable surface finishes for cosmetic and functional applications.
Quick Answer
What is polishing for titanium? Mechanical polishing uses progressive abrasive grits to achieve mirror-like surfaces on titanium. Typical sequences start at 120-grit and progress through 240, 400, 600, 800, 1000, and up to 3000-grit for mirror finishes.
Grit Sequence
| Stage | Grit | Resulting Ra |
|---|---|---|
| Rough | 120鈥?40 | 0.8 碌m |
| Intermediate | 400鈥?00 | 0.4 碌m |
| Fine | 800鈥?200 | 0.2 碌m |
| Mirror | 2000鈥?000+ | 0.05 碌m |
