VT machining offers CNC Turning for Grade 23 Titanium (UNS R56401 / Ti-6Al-4V ELI), typically supplied annealed. Extra-low-interstitial Gr5 with better fracture toughness, for implants.
CNC Turning Notes for Grade 23 Titanium
On the lathe Grade 23 Titanium needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
For estimating, a 100 × 100 × 10 mm block of Grade 23 Titanium weighs about 0.44 kg.

Request a QuoteFrequently Asked Questions
What tolerances can you hold for CNC Turning Grade 23 Titanium?
Achievable tolerances for Grade 23 Titanium turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Turning Grade 23 Titanium?
Turned Grade 23 Titanium parts are produced from bar or chuck stock across a wide diameter range.
Can VT machining make custom Grade 23 Titanium parts to my drawing?
Yes. Grade 23 Titanium turning 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.
Does CNC Turning Grade 23 Titanium require dedicated tooling?
Most Grade 23 Titanium turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
