VT machining provides CNC Sinker EDM NAK80 Mold Steel for customers who need accurate, repeatable NAK80 Mold Steel components. The machinability of NAK80 Mold Steel is pre-hardened or machined-then-hardened; polishes to high finish for molds, so we set the operation up specifically for this grade.
CNC Sinker EDM Capability for NAK80 Mold Steel
- Mold-grade cleanliness
- Polishable to mirror finish
- Hardenable to 48–54 HRC
- Tolerance to ±0.005 mm

Published typical values for WC-Co (YG8 / K20). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Everything is done by grinding, wire EDM or sinker EDM. Design in a small corner radius wherever possible — a true sharp internal corner doubles the EDM time.
Machining NAK80 Mold Steel with CNC Sinker EDM
NAK80 Mold Steel behaves predictably under CNC Sinker EDM once parameters are dialled in: machinability is pre-hardened or machined-then-hardened; polishes to high finish for molds, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of NAK80 Mold Steel run consistently from one batch to the next.
Achievable Tolerances for CNC Sinker EDM NAK80 Mold Steel
| 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 NAK80 Mold Steel?
NAK80 Mold Steel is chosen when a part needs what this grade offers — it is mold-grade, polishable and hardenable. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Sinker EDM 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 NAK80 Mold Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the NAK80 Mold Steel 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.
Secondary Operations & Finishing
Finished NAK80 Mold Steel 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.
Design Tips for CNC Sinker EDM NAK80 Mold Steel
We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened NAK80 Mold Steel 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.
Applications of CNC Sinker EDM NAK80 Mold Steel
Customers order CNC Sinker EDM NAK80 Mold Steel 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 Sinker EDM NAK80 Mold Steel
- 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 NAK80 Mold Steel 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.
