- Tolerance to ±0.02 mm
- Plating-ready
Machining ZA-8 Zinc Alloy with CNC Wire EDM
When EDM machining ZA-8 Zinc Alloy, machinability is good; commonly die-cast then machined to final tolerance. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for ZA-8 Zinc Alloy mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Wire EDM ZA-8 Zinc Alloy
| Feature | Standard | Precision |
|---|---|---|
| Profile dimension | ±0.010 mm | ±0.002 mm |
| Internal corner radius | 0.15 mm | 0.05 mm |
| Taper control over 50 mm | 0.02 mm | 0.005 mm |
| Surface finish (skim passes) | Ra 0.8 µm | Ra 0.2 µm |
| Recast layer | 10 µm | 2 µm (fine skim) |
| Start-hole diameter | 1.0 mm | 0.25 mm |
| Workpiece hardness | no limit (conductive) | no limit (conductive) |
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 ZA-8 Zinc Alloy?
Customers select ZA-8 Zinc Alloy for CNC Wire EDM because it is dimensionally stable and easy to finish. We handle grade verification and any required heat treatment or finishing.
Secondary Operations & Finishing
Most ZA-8 Zinc Alloy parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Design Tips for CNC Wire EDM ZA-8 Zinc Alloy
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened ZA-8 Zinc Alloy 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.
CNC Wire EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the ZA-8 Zinc Alloy part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
CNC Wire EDM Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Applications of CNC Wire EDM ZA-8 Zinc Alloy
ZA-8 Zinc Alloy parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC Wire EDM ZA-8 Zinc Alloy
- 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 ZA-8 Zinc Alloy 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.

What tolerances can you hold for CNC Wire EDM ZA-8 Zinc Alloy?
Achievable tolerances for ZA-8 Zinc Alloy EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.
Why is ZA-8 Zinc Alloy a good choice for CNC Wire EDM?
ZA-8 Zinc Alloy is dimensionally stable and easy to finish, which makes it well suited to CNC Wire EDM. We tune the process to the alloy so the finished ZA-8 Zinc Alloy EDM machining part meets your dimensional and functional requirements.
What is CNC Wire EDM ZA-8 Zinc Alloy and how is it done?
CNC Wire EDM ZA-8 Zinc Alloy refers to wire EDM cuts conductive metal with a charged wire, achieving fine detail and tight tolerance with no cutting force. Applied to ZA-8 Zinc Alloy — dimensionally stable and easy to finish — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can you EDM-machine hardened ZA-8 Zinc Alloy?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult ZA-8 Zinc Alloy can be machined to fine detail and tight tolerance without distortion.
