CNC Boring ZA-8 Zinc Alloy from VT machining delivers precision ZA-8 Zinc Alloy parts made to your exact drawing. Boring enlarges and finishes existing holes to precise diameter, roundness and surface finish, with parameters tuned to ZA-8 Zinc Alloy, which is dimensionally stable and easy to finish.
CNC Boring Capability for ZA-8 Zinc Alloy
- Die-cast + machined
- Good dimensional stability
- Tolerance to ±0.02 mm
- Plating-ready
Machining ZA-8 Zinc Alloy with CNC Boring
ZA-8 Zinc Alloy behaves predictably under CNC Boring once parameters are dialled in: machinability is good; commonly die-cast then machined to final tolerance, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of ZA-8 Zinc Alloy run consistently from one batch to the next.
Achievable Tolerances for CNC Boring ZA-8 Zinc Alloy
| Feature | Standard | Precision |
|---|---|---|
| Outside diameter | ±0.05 mm | ±0.005 mm |
| Bore diameter | H9 | H6 |
| Length / shoulder position | ±0.10 mm | ±0.020 mm |
| Concentricity OD to ID | 0.05 mm TIR | 0.010 mm TIR |
| Roundness | 0.02 mm | 0.005 mm |
| Thread class | 6g / 2A | 4h / 3A |
| Surface finish, as turned | 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.
CNC Boring Tolerances & Surface Finish
Turned ZA-8 Zinc Alloy holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
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.
Why ZA-8 Zinc Alloy?
ZA-8 Zinc Alloy is chosen when a part needs what this grade offers — it is dimensionally stable and easy to finish. We confirm the grade and any temper or heat-treat condition with you before machining.
Design Tips for CNC Boring ZA-8 Zinc Alloy
We are happy to suggest design tweaks that improve manufacturability. Consistent diameters, standard thread forms and avoiding extremely long, slender features help ZA-8 Zinc Alloy turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Boring 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 ZA-8 Zinc Alloy part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Secondary Operations & Finishing
Finished ZA-8 Zinc Alloy 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.
Applications of CNC Boring ZA-8 Zinc Alloy
Customers order CNC Boring ZA-8 Zinc Alloy 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 Boring 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.
