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 Surface Grinding
The machinability of Grade 12 Titanium is difficult; low speeds, high feeds, flood coolant to manage heat. For CNC Surface Grinding we select tooling, feeds, speeds and coolant to match, keeping the Grade 12 Titanium workpiece stable and the result accurate.
Because we machine Grade 12 Titanium regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Surface Grinding Grade 12 Titanium
| Feature | Standard | Precision |
|---|---|---|
| Size (OD, ID, thickness) | ±0.005 mm | ±0.002 mm |
| Flatness over 100 mm | 0.010 mm | 0.003 mm |
| Parallelism | 0.010 mm | 0.003 mm |
| Roundness | 0.005 mm | 0.002 mm |
| Squareness | 0.010 mm | 0.005 mm |
| Surface finish | Ra 0.4 µm | Ra 0.1 µm |
| Workpiece hardness | up to 62 HRC | up to 65 HRC |
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 Surface Grinding Tolerances & Surface Finish
Ground Grade 12 Titanium reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Secondary Operations & Finishing
We complete Grade 12 Titanium components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Design Tips for CNC Surface Grinding Grade 12 Titanium
A few design choices make a real difference to cost and quality. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on Grade 12 Titanium efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Why Grade 12 Titanium?
Specifying Grade 12 Titanium for CNC Surface Grinding Grade 12 Titanium is usually about its properties: high strength-to-weight, biocompatible and corrosion resistant. Tell us the condition you need and we machine to it.
CNC Surface Grinding Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Grade 12 Titanium parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Applications of CNC Surface Grinding Grade 12 Titanium
CNC Surface Grinding of Grade 12 Titanium supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

What We Need to Quote CNC Surface Grinding 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.
