VT machining specialises in CNC Punching NAK80 Mold Steel. Because NAK80 Mold Steel is mold-grade, polishable and hardenable, and its machinability is pre-hardened or machined-then-hardened; polishes to high finish for molds, we plan each job around the grade to protect accuracy and surface quality.
CNC Punching 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 Punching
The machinability of NAK80 Mold Steel is pre-hardened or machined-then-hardened; polishes to high finish for molds. For CNC Punching we select tooling, feeds, speeds and coolant to match, keeping the NAK80 Mold Steel workpiece stable and the result accurate.
Because we machine NAK80 Mold Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Punching NAK80 Mold Steel
| Feature | Standard | Precision |
|---|---|---|
| Hole position across sheet | ±0.15 mm | ±0.10 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Overall blank size | ±0.20 mm | ±0.10 mm |
| Minimum hole | 1.0 × thickness | 0.8 × thickness |
| Hole-to-edge distance | 2.0 × thickness | 1.5 × thickness |
| Burr height | 0.08 mm | 0.03 mm (deburred) |
| Sheet thickness range | 0.5–6.0 mm | 0.5–3.0 mm |
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.
Secondary Operations & Finishing
We complete NAK80 Mold Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
CNC Punching Tolerances & Surface Finish
Punched NAK80 Mold Steel holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
CNC Punching Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on NAK80 Mold Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Design Tips for CNC Punching NAK80 Mold Steel
A few design choices make a real difference to cost and quality. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched NAK80 Mold Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
Why NAK80 Mold Steel?

What We Need to Quote CNC Punching 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.
