Titanium CNC Machining
Titanium offers the best strength-to-weight ratio of any structural metal — essential for aerospace, medical implants, and high-performance applications where every gram matters.
Alloy Grades & Properties
| Grade | Properties | Applications |
|---|---|---|
| Grade 2 (CP Ti) | Ductile, excellent corrosion resistance, biocompatible | Medical implants, chemical processing, marine |
| Grade 5 (Ti-6Al-4V) | High strength, heat treatable, aerospace standard | Aerospace structures, engine components, racing |
| Grade 5 ELI | Extra low interstitials — enhanced fracture toughness | Medical implants, surgical instruments |
| Grade 23 (Ti-6Al-4V ELI) | Improved ductility for medical implants | Orthopedic and dental implants |
Machining Tolerances
Standard ±0.05mm · Precision ±0.01mm · Medical implants ±0.005mm with CMM
Surface Finishing Options
- Passivation
- Anodizing (color coding for medical)
- Electropolishing
- Tumbling & deburring
- Laser marking (UDI compliance)
Common Applications
- Aerospace structural and engine parts
- Medical implants and surgical tools
- Racing and motorsport components
- Marine propeller shafts
- High-performance bicycle parts
DFM & Machining Tips
- Use low cutting speeds and high feed rates — titanium work-hardens easily
- Generous coolant flow is essential to prevent heat buildup
- Dedicated titanium tooling — never mix with steel setups to avoid contamination
- Design stiff structures — titanium parts are often thin-walled and flexible
Frequently Asked Questions
Why is titanium machining expensive?
Titanium work-hardens, requires slow cutting speeds, specialized tooling, and strict contamination control. Material cost is also higher. We optimize designs via DFM to minimize cost.
Grade 2 vs Grade 5 — which do I need?
Grade 2 for corrosion-critical, biocompatible applications needing ductility. Grade 5 when maximum strength-to-weight is required (aerospace, high-stress structural).
Do you machine medical titanium implants?
Yes — Ti-6Al-4V ELI with Swiss-type turning and 5-axis milling. Passivation, electropolishing, and laser UDI marking available.
