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.
How CNC Thread Grinding Titanium Works
An abrasive wheel removes a fine, controlled layer from the Titanium part. Wheel specification, dressing interval, infeed and coolant are matched to the alloy's hardness so the surface is not burned or left with residual stress.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.
Achievable Tolerances for CNC Thread Grinding 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.
Secondary Operations & Finishing
We complete 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.
CNC Thread Grinding Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 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.
CNC Thread Grinding Tolerances & Surface Finish
Ground 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.
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.
Design Tips for CNC Thread Grinding 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 Titanium efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Titanium
Titanium offers a useful combination of properties: it is high strength-to-weight, biocompatible, corrosion resistant. Those characteristics shape how we approach grinding — from tool and parameter selection to work-holding and coolant.
If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.
Applications of CNC Thread Grinding Titanium
CNC Thread Grinding of 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.
How to Order CNC Thread Grinding Titanium
Ordering Titanium parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.

What We Need to Quote CNC Thread Grinding 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 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.
