VT machining offers CNC Boring for Grade 7 Titanium (UNS R52400 / ASTM B348 Gr7), typically supplied annealed. Gr2 with palladium for superior resistance in reducing acids.
CNC Boring Notes for Grade 7 Titanium
Boring bars for Grade 7 Titanium are chosen for rigidity, with sharp inserts and light finishing passes to avoid chatter and smearing.
For estimating, a 100 × 100 × 10 mm block of Grade 7 Titanium weighs about 0.45 kg.

Does CNC Boring Grade 7 Titanium require dedicated tooling?
Most Grade 7 Titanium turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Boring Grade 7 Titanium?
CNC Boring prototypes for Grade 7 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 material thickness or size range suits CNC Boring Grade 7 Titanium?
Turned Grade 7 Titanium parts are produced from bar or chuck stock across a wide diameter range.
What surface finish is achievable on Grade 7 Titanium with CNC Boring?
Surface finish on Grade 7 Titanium is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Boring Grade 7 Titanium?
Achievable tolerances for Grade 7 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.
