VT machining specialises in CNC Punching Grade 2 Titanium. Because Grade 2 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 Punching Capability for Grade 2 Titanium
- High strength-to-weight
- Biocompatible
- Corrosion resistant
- Tolerance to ±0.01 mm
Grade 2 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 2 Titanium with CNC Punching
The machinability of Grade 2 Titanium is difficult; low speeds, high feeds, flood coolant to manage heat. For CNC Punching we select tooling, feeds, speeds and coolant to match, keeping the Grade 2 Titanium workpiece stable and the result accurate.
Because we machine Grade 2 Titanium regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Punching Grade 2 Titanium
| Feature | Standard | Precision |
|---|---|---|
| Hole position across sheet | ±0.15 mm | ±0.10 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Overall blank size | ±0.20 mm | ±0.10 mm |
| Minimum hole | 1.0 × thickness | 0.8 × thickness |
| Hole-to-edge distance | 2.0 × thickness | 1.5 × thickness |
| Burr height | 0.08 mm | 0.03 mm (deburred) |
| Sheet thickness range | 0.5–6.0 mm | 0.5–3.0 mm |
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.
Design Tips for CNC Punching Grade 2 Titanium
A few design choices make a real difference to cost and quality. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched Grade 2 Titanium. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Punching Tolerances & Surface Finish
Punched Grade 2 Titanium holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
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 2 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 Punching Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Grade 2 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.
Why Grade 2 Titanium?
Specifying Grade 2 Titanium for CNC Punching Grade 2 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.
Applications of CNC Punching Grade 2 Titanium

What We Need to Quote CNC Punching 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.
