VT machining specialises in CNC Deburring Grade 4 Titanium. Because Grade 4 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 Deburring Capability for Grade 4 Titanium
- High strength-to-weight
- Biocompatible
- Corrosion resistant
- Tolerance to ±0.01 mm
Grade 4 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% |

| 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 4 Titanium with CNC Deburring
Grade 4 Titanium behaves predictably under CNC Deburring 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 4 Titanium run consistently from one batch to the next.
Achievable Tolerances for CNC Deburring Grade 4 Titanium
| Feature | Standard | Precision |
|---|---|---|
| Surface roughness | Ra 0.8 µm | Ra 0.05 µm |
| Edge break | 0.1–0.3 mm | 0.05 ±0.02 mm |
| Material removed | 0.02 mm | 0.005 mm |
| Bore roundness after honing | 0.005 mm | 0.002 mm |
| Cross-hatch angle | 45° ±10° | 45° ±5° |
| Cosmetic grade | uniform satin | mirror, no visible lines |
| Masking of datum faces | on request | standard |
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 4 Titanium?
Grade 4 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.
Design Tips for CNC Deburring Grade 4 Titanium
We are happy to suggest design tweaks that improve manufacturability. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish Grade 4 Titanium efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Finished Grade 4 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.
CNC Deburring Tolerances & Surface Finish
Finishing brings Grade 4 Titanium to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
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.
CNC Deburring 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 4 Titanium part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Applications of CNC Deburring Grade 4 Titanium
Customers order CNC Deburring Grade 4 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 Deburring Grade 4 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 4 Titanium
| Finish | Thickness / effect | Why it gets specified |

| Type II anodise | — | Colour coding, biocompatible |
| Type III anodise | — | Anti-galling for threaded and sliding parts |
| Passivation | — | ASTM F86 for implant-grade parts |
| Electropolish | 5–20 µm removed | Removes the machining layer for medical use |
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Deburring Grade 4 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 4 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.
