VT machining provides CNC Surface Grinding 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 Surface Grinding 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 Surface Grinding
NAK80 Mold Steel behaves predictably under CNC Surface Grinding 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 Surface Grinding NAK80 Mold Steel
| Feature | Standard | Precision |
|---|---|---|
| Size (OD, ID, thickness) | ±0.005 mm | ±0.002 mm |
| Flatness over 100 mm | 0.010 mm | 0.003 mm |
| Parallelism | 0.010 mm | 0.003 mm |
| Roundness | 0.005 mm | 0.002 mm |
| Squareness | 0.010 mm | 0.005 mm |
| Surface finish | Ra 0.4 µm | Ra 0.1 µm |
| Workpiece hardness | up to 62 HRC | up to 65 HRC |
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 Surface Grinding 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.
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 Surface Grinding Tolerances & Surface Finish
Ground NAK80 Mold Steel reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
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.
Design Tips for CNC Surface Grinding NAK80 Mold Steel
We are happy to suggest design tweaks that improve manufacturability. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on NAK80 Mold Steel efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
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.
Applications of CNC Surface Grinding NAK80 Mold Steel
Customers order CNC Surface Grinding 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.
How to Order CNC Surface Grinding NAK80 Mold Steel
Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
Finishing Options for NAK80 Mold Steel

What We Need to Quote CNC Surface Grinding 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.
