VT machining specialises in CNC Boring Ti-6Al-4V Titanium. Because Ti-6Al-4V Titanium is high strength-to-weight, biocompatible and corrosion resistant, and its machinability is difficult; low speeds, high feeds, flood coolant to manage heat, we plan each job around the grade to protect accuracy and surface quality.

Published typical values for Ti-6Al-4V (Gr 5). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Heat has nowhere to go — thermal conductivity is 1/25th of aluminium, so it all goes into the tool. Low surface speed, heavy feed, flood coolant, and the cutter never stops moving.
Machining Ti-6Al-4V Titanium with CNC Boring
Ti-6Al-4V Titanium behaves predictably under CNC Boring once parameters are dialled in: machinability is difficult; low speeds, high feeds, flood coolant to manage heat, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of Ti-6Al-4V Titanium run consistently from one batch to the next.
Achievable Tolerances for CNC Boring Ti-6Al-4V Titanium
| Feature | Standard | Precision |
|---|---|---|
| Outside diameter | ±0.05 mm | ±0.005 mm |
| Bore diameter | H9 | H6 |
| Length / shoulder position | ±0.10 mm | ±0.020 mm |
| Concentricity OD to ID | 0.05 mm TIR | 0.010 mm TIR |
| Roundness | 0.02 mm | 0.005 mm |
| Thread class | 6g / 2A | 4h / 3A |
| Surface finish, as turned | Ra 1.6 µm | Ra 0.4 µm |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Design Tips for CNC Boring Ti-6Al-4V Titanium
We are happy to suggest design tweaks that improve manufacturability. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Ti-6Al-4V Titanium turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
Why Ti-6Al-4V Titanium?
Ti-6Al-4V Titanium is chosen when a part needs what this grade offers — it is high strength-to-weight, biocompatible and corrosion resistant. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Boring Tolerances & Surface Finish
Turned Ti-6Al-4V Titanium holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Secondary Operations & Finishing
Finished Ti-6Al-4V Titanium parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
CNC Boring Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every Ti-6Al-4V Titanium part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Applications of CNC Boring Ti-6Al-4V Titanium
Customers order CNC Boring Ti-6Al-4V Titanium components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

What We Need to Quote CNC Boring Ti-6Al-4V Titanium
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact Ti-6Al-4V Titanium grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.
