CNC EDM Drilling AZ91D Magnesium

VT machining specialises in CNC EDM Drilling AZ91D Magnesium. Because AZ91D 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 EDM Drilling Capability for AZ91D Magnesium

  • Lightest structural metal (~1.8 g/cm³)
  • Excellent machinability
  • High strength-to-weight
  • Damping capacity

Machining AZ91D Magnesium with CNC EDM Drilling

AZ91D Magnesium behaves predictably under CNC EDM Drilling once parameters are dialled in: machinability is excellent (fastest of structural metals); fire-safe chip handling required, and we tune the operation accordingly.

We hold reference parameters for this grade, so repeat orders of AZ91D Magnesium run consistently from one batch to the next.

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 EDM Drilling AZ91D Magnesium

We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened AZ91D Magnesium that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.

Why AZ91D Magnesium?

AZ91D Magnesium is chosen when a part needs what this grade offers — it is ultralight with excellent machinability. We confirm the grade and any temper or heat-treat condition with you before machining.

CNC EDM Drilling 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 AZ91D Magnesium part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.

Secondary Operations & Finishing

Finished AZ91D Magnesium 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 EDM Drilling Tolerances & Surface Finish

EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the AZ91D Magnesium part, producing fine, controlled surface textures and sharp internal corners impossible to mill.

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.

Applications of CNC EDM Drilling AZ91D Magnesium

Customers order CNC EDM Drilling AZ91D Magnesium 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.

What We Need to Quote CNC EDM Drilling AZ91D 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 AZ91D 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.
