CNC Engraving Grade 4 Titanium from VT machining delivers precision Grade 4 Titanium parts made to your exact drawing. CNC engraving marks logos, text, serial data and fine detail by removing a controlled depth of metal, with parameters tuned to Grade 4 Titanium, which is high strength-to-weight, biocompatible and corrosion resistant.

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 4 Titanium with CNC Engraving
When machining Grade 4 Titanium, machinability is difficult; low speeds, high feeds, flood coolant to manage heat. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for Grade 4 Titanium mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Engraving Grade 4 Titanium
| Feature | Standard | Precision |
|---|---|---|
| Linear dimension (< 100 mm) | ±0.05 mm | ±0.010 mm |
| Linear dimension (100–300 mm) | ±0.10 mm | ±0.025 mm |
| Hole diameter (reamed) | H9 | H7 |
| True position of hole pattern | ±0.10 mm | ±0.025 mm |
| Flatness over 100 mm | 0.05 mm | 0.015 mm |
| Perpendicularity | 0.10 mm | 0.020 mm |
| Surface finish, as machined | 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.
CNC Engraving Tolerances & Surface Finish
For CNC Engraving, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
CNC Engraving Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Secondary Operations & Finishing
Most Grade 4 Titanium parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Why Grade 4 Titanium?
Customers select Grade 4 Titanium for CNC Engraving because it is high strength-to-weight, biocompatible and corrosion resistant. We handle grade verification and any required heat treatment or finishing.
Design Tips for CNC Engraving Grade 4 Titanium
Small design adjustments often cut cost and lead time. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in Grade 4 Titanium. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Engraving Grade 4 Titanium
Grade 4 Titanium parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Engraving Grade 4 Titanium

Finishing Options for Grade 4 Titanium
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Type II anodise | — | Colour coding, biocompatible |
| Type III anodise | — | Anti-galling for threaded and sliding parts |

What We Need to Quote CNC Engraving Grade 4 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 4 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.
