VT machining specialises in CNC Wire EDM Grade 12 Titanium. Because Grade 12 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 Wire EDM Capability for Grade 12 Titanium
- High strength-to-weight
- Biocompatible
- Corrosion resistant
- Tolerance to ±0.01 mm

| Grades we run | Gr 1, Gr 2 (CP), Gr 5 Ti-6Al-4V, Gr 23 ELI, Gr 7, Gr 9 |
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 12 Titanium with CNC Wire EDM
When EDM machining Grade 12 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 12 Titanium mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Wire EDM Grade 12 Titanium
| Feature | Standard | Precision |
|---|---|---|
| Profile dimension | ±0.010 mm | ±0.002 mm |
| Internal corner radius | 0.15 mm | 0.05 mm |
| Taper control over 50 mm | 0.02 mm | 0.005 mm |
| Surface finish (skim passes) | Ra 0.8 µm | Ra 0.2 µm |
| Recast layer | 10 µm | 2 µm (fine skim) |
| Start-hole diameter | 1.0 mm | 0.25 mm |
| Workpiece hardness | no limit (conductive) | no limit (conductive) |
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.
Why Grade 12 Titanium?
Customers select Grade 12 Titanium for CNC Wire EDM because it is high strength-to-weight, biocompatible and corrosion resistant. We handle grade verification and any required heat treatment or finishing.
CNC Wire EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Grade 12 Titanium part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
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.
Design Tips for CNC Wire EDM Grade 12 Titanium
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Grade 12 Titanium that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Most Grade 12 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.
CNC Wire EDM 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.
Applications of CNC Wire EDM Grade 12 Titanium
Grade 12 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 Wire EDM Grade 12 Titanium
Starting your project takes one email. Send your CAD or 2D drawing, the Grade 12 Titanium grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.
Finishing Options for Grade 12 Titanium
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Type II anodise | — | Colour coding, biocompatible |
| Type III anodise | — | Anti-galling for threaded and sliding parts |
| Passivation | — | ASTM F86 for implant-grade parts |
| Electropolish | 5–20 µm removed | Removes the machining layer for medical use |
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Wire EDM Grade 12 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 12 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.
