VT machining provides CNC Gear Hobbing Grade 12 Titanium for customers who need accurate, repeatable Grade 12 Titanium components. The machinability of Grade 12 Titanium is difficult; low speeds, high feeds, flood coolant to manage heat, so we set the operation up specifically for this grade.
CNC Gear Hobbing Capability for Grade 12 Titanium
- High strength-to-weight
- Biocompatible
- Corrosion resistant
- Tolerance to ±0.01 mm
Grade 12 Titanium Material Data
| Density | 4.43 g/cm³ |
|---|---|
| Tensile strength | 950 MPa |
| Yield strength (0.2%) | 880 MPa |
| Hardness | 334 HB / 36 HRC |
| Melting point | 1604–1660 °C |
| Thermal conductivity | 6.7 W/m·K |
| Thermal expansion | 8.6 ×10⁻⁶/K |
| Electrical conductivity | 3.1% |
| Machinability (C36000 = 100%) | 22% |
| 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 Gear Hobbing
Grade 12 Titanium behaves predictably under CNC Gear Hobbing 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 12 Titanium run consistently from one batch to the next.
Achievable Tolerances for CNC Gear Hobbing Grade 12 Titanium
| Feature | Standard | Precision |
|---|---|---|
| Accuracy class | DIN 8 / AGMA 10 | DIN 6 / AGMA 12 |
| Profile deviation | 0.020 mm | 0.008 mm |
| Lead deviation | 0.020 mm | 0.008 mm |
| Pitch deviation (cumulative) | 0.040 mm | 0.015 mm |
| Runout | 0.030 mm | 0.010 mm |
| Tooth surface finish | Ra 1.6 µm | Ra 0.4 µm (ground) |
| Module range | m0.5–m8 | m1–m6 |
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?
Grade 12 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 Gear Hobbing 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 12 Titanium part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Secondary Operations & Finishing
Finished Grade 12 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.
Design Tips for CNC Gear Hobbing Grade 12 Titanium
We are happy to suggest design tweaks that improve manufacturability. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Grade 12 Titanium gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Gear Hobbing Tolerances & Surface Finish
Gear features are produced to a specified DIN/AGMA accuracy class, with profile and lead controlled for quiet, durable running under load.
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.
Applications of CNC Gear Hobbing Grade 12 Titanium
Customers order CNC Gear Hobbing Grade 12 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.
How to Order CNC Gear Hobbing Grade 12 Titanium
Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
Finishing Options for Grade 12 Titanium
| Finish | Thickness / effect | Why it gets specified |

What We Need to Quote CNC Gear Hobbing 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.
