CNC Gear Hobbing Grade 2 Titanium from VT machining delivers precision Grade 2 Titanium parts made to your exact drawing. Gear hobbing generates gear teeth with a rotating hob synchronized to the workpiece, with parameters tuned to Grade 2 Titanium, which is high strength-to-weight, biocompatible and corrosion resistant.

|---|---|
| Tensile strength | 950 MPa |
| Yield strength (0.2%) | 880 MPa |
| Hardness | 334 HB / 36 HRC |
| Melting point | 1604–1660 °C |

| 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 2 Titanium with CNC Gear Hobbing
When gear cutting Grade 2 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 2 Titanium mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Gear Hobbing Grade 2 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.
CNC Gear Hobbing 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 2 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 2 Titanium?
Customers select Grade 2 Titanium for CNC Gear Hobbing because it is high strength-to-weight, biocompatible and corrosion resistant. We handle grade verification and any required heat treatment or finishing.
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.
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 Gear Hobbing Grade 2 Titanium
Small design adjustments often cut cost and lead time. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Grade 2 Titanium gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Gear Hobbing Grade 2 Titanium
Grade 2 Titanium parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC Gear Hobbing Grade 2 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 2 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.
