CNC Milling Grade 23 Titanium

VT machining offers CNC Milling for Grade 23 Titanium (UNS R56401 / Ti-6Al-4V ELI), typically supplied annealed. Extra-low-interstitial Gr5 with better fracture toughness, for implants.

CNC Milling Notes for Grade 23 Titanium

We use high-efficiency toolpaths with constant engagement on Grade 23 Titanium to keep cutting temperature and tool wear under control.

For estimating, a 100 × 100 × 10 mm block of Grade 23 Titanium weighs about 0.44 kg.

Frequently Asked Questions

What tolerances can you hold for CNC Milling Grade 23 Titanium?

Achievable tolerances for Grade 23 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 23 Titanium parts to my drawing?

Yes. Grade 23 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.

What is CNC Milling Grade 23 Titanium and how is it done?

CNC Milling Grade 23 Titanium refers to multi-axis milling cutters remove material to produce prismatic features, pockets, slots and contoured 3D surfaces. Applied to Grade 23 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.

What is the typical lead time and minimum order for CNC Milling Grade 23 Titanium?

CNC Milling prototypes for Grade 23 Titanium can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.

What surface finish is achievable on Grade 23 Titanium with CNC Milling?

Surface finish on Grade 23 Titanium is controlled to your specification; we confirm the achievable Ra against your callout.

Why is Grade 23 Titanium a good choice for CNC Milling?

Grade 23 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 Grade 23 Titanium machining part meets your dimensional and functional requirements.
