VT machining specialises in CNC Milling AZ31B Magnesium. Because AZ31B Magnesium is ultralight with excellent machinability, and its machinability is excellent (fastest of structural metals); fire-safe chip handling required, we plan each job around the grade to protect accuracy and surface quality.
CNC Milling Capability for AZ31B Magnesium
- Lightest structural metal (~1.8 g/cm³)
- Excellent machinability
- High strength-to-weight
- Damping capacity
Machining AZ31B Magnesium with CNC Milling
The machinability of AZ31B Magnesium is excellent (fastest of structural metals); fire-safe chip handling required. For CNC Milling we select tooling, feeds, speeds and coolant to match, keeping the AZ31B Magnesium workpiece stable and the result accurate.
Because we machine AZ31B Magnesium regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Milling AZ31B Magnesium
| Feature | Standard | Precision |
|---|---|---|
| Linear dimension (< 100 mm) | ±0.05 mm | ±0.010 mm |
| Linear dimension (100–300 mm) | ±0.10 mm | ±0.025 mm |
| Hole diameter (reamed) | H9 | H7 |
| True position of hole pattern | ±0.10 mm | ±0.025 mm |
| Flatness over 100 mm | 0.05 mm | 0.015 mm |
| Perpendicularity | 0.10 mm | 0.020 mm |
| Surface finish, as machined | Ra 1.6 µm | Ra 0.4 µm |
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 Milling AZ31B Magnesium
A few design choices make a real difference to cost and quality. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in AZ31B Magnesium. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Milling Tolerances & Surface Finish
For CNC Milling, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
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 AZ31B Magnesium 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 Milling Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on AZ31B Magnesium 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.

What We Need to Quote CNC Milling AZ31B Magnesium
- 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 AZ31B Magnesium 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.
