VT machining offers CNC 5-Axis Machining for Grade 3 Titanium (UNS R50550 / ASTM B348 Gr3), typically supplied annealed. Stronger CP grade than Gr2 with slightly lower formability.
CNC 5-Axis Machining Notes for Grade 3 Titanium
For a hard-to-cut grade like Grade 3 Titanium, multi-axis machining reduces the number of setups, so there are fewer re-clamps and less time spent cutting.
For estimating, a 100 × 100 × 10 mm block of Grade 3 Titanium weighs about 0.45 kg.

Why is Grade 3 Titanium a good choice for CNC 5-Axis Machining?
Grade 3 Titanium is high strength-to-weight, biocompatible and corrosion resistant, which makes it well suited to CNC 5-Axis Machining. We tune the process to the alloy so the finished Grade 3 Titanium machining part meets your dimensional and functional requirements.
Does CNC 5-Axis Machining Grade 3 Titanium require dedicated tooling?
Most Grade 3 Titanium machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What tolerances can you hold for CNC 5-Axis Machining Grade 3 Titanium?
Achievable tolerances for Grade 3 Titanium machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom Grade 3 Titanium parts to my drawing?
Yes. Grade 3 Titanium machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
