VT machining offers CNC Milling for Ti-6Al-4V Titanium (UNS R56400 / R56401 (ELI) / TC4), typically supplied annealed or STA. Same alloy as Grade 5; ELI version (Gr23) is specified for implants.
CNC Milling Notes for Ti-6Al-4V Titanium
We use high-efficiency toolpaths with constant engagement on Ti-6Al-4V Titanium to keep cutting temperature and tool wear under control.
For estimating, a 100 × 100 × 10 mm block of Ti-6Al-4V Titanium weighs about 0.44 kg.

What tolerances can you hold for CNC Milling Ti-6Al-4V Titanium?
Achievable tolerances for Ti-6Al-4V 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.
Why is Ti-6Al-4V Titanium a good choice for CNC Milling?
Ti-6Al-4V Titanium is high strength-to-weight, biocompatible and corrosion resistant, which makes it well suited to CNC Milling. We tune the process to the alloy so the finished Ti-6Al-4V Titanium machining part meets your dimensional and functional requirements.
What surface finish is achievable on Ti-6Al-4V Titanium with CNC Milling?
Surface finish on Ti-6Al-4V Titanium is controlled to your specification; we confirm the achievable Ra against your callout.
Can VT machining make custom Ti-6Al-4V Titanium parts to my drawing?
Yes. Ti-6Al-4V 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.
