VT machining offers CNC Lathe Machining for Grade 3 Titanium (UNS R50550 / ASTM B348 Gr3), typically supplied annealed. Stronger CP grade than Gr2 with slightly lower formability.
CNC Lathe Machining Notes for Grade 3 Titanium
On the lathe Grade 3 Titanium needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
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 Lathe Machining?
Grade 3 Titanium is high strength-to-weight, biocompatible and corrosion resistant, which makes it well suited to CNC Lathe Machining. We tune the process to the alloy so the finished Grade 3 Titanium turning part meets your dimensional and functional requirements.
What is CNC Lathe Machining Grade 3 Titanium and how is it done?
CNC Lathe Machining Grade 3 Titanium refers to cNC lathe machining produces precision rotational parts with combined turning, facing, drilling and threading. Applied to Grade 3 Titanium — high strength-to-weight, biocompatible and corrosion resistant — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
How clean are the edges produced by CNC Lathe Machining on Grade 3 Titanium?
Machined Grade 3 Titanium edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Can VT machining make custom Grade 3 Titanium parts to my drawing?
Yes. Grade 3 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.
What material thickness or size range suits CNC Lathe Machining Grade 3 Titanium?
Turned Grade 3 Titanium parts are produced from bar or chuck stock across a wide diameter range.
What surface finish is achievable on Grade 3 Titanium with CNC Lathe Machining?
Surface finish on Grade 3 Titanium is controlled to your specification; we confirm the achievable Ra against your callout.
