VT machining specialises in CNC Punching Grade 5 Titanium. Because Grade 5 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.
CNC Punching Capability for Grade 5 Titanium
- High strength-to-weight
- Biocompatible
- Corrosion resistant
- Tolerance to ±0.01 mm

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 Grade 5 Titanium with CNC Punching
Grade 5 Titanium behaves predictably under CNC Punching 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 Grade 5 Titanium run consistently from one batch to the next.
Achievable Tolerances for CNC Punching Grade 5 Titanium
| Feature | Standard | Precision |
|---|---|---|
| Hole position across sheet | ±0.15 mm | ±0.10 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Overall blank size | ±0.20 mm | ±0.10 mm |
| Minimum hole | 1.0 × thickness | 0.8 × thickness |
| Hole-to-edge distance | 2.0 × thickness | 1.5 × thickness |
| Burr height | 0.08 mm | 0.03 mm (deburred) |
| Sheet thickness range | 0.5–6.0 mm | 0.5–3.0 mm |
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.
CNC Punching 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 Grade 5 Titanium part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Why Grade 5 Titanium?
Grade 5 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.
Secondary Operations & Finishing
Finished Grade 5 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 Punching Tolerances & Surface Finish
Punched Grade 5 Titanium holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
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.
Design Tips for CNC Punching Grade 5 Titanium
We are happy to suggest design tweaks that improve manufacturability. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched Grade 5 Titanium. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Punching Grade 5 Titanium
Customers order CNC Punching Grade 5 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 Punching Grade 5 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 Grade 5 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.
