Two phases with very different behaviour in one part. EDM gives a far more consistent result than milling on fine features, and it is the usual route for heat-spreader profiles.
How CNC Punching Tungsten Copper Works
A CNC turret presses hardened punches through the Tungsten Copper sheet into matching dies. Punch-to-die clearance is set as a percentage of thickness so the cut edge stays clean and burr is minimal.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.
Achievable Tolerances for CNC Punching Tungsten Copper
| 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.
Working with Tungsten Copper
Tungsten Copper offers a useful combination of properties: it is combines tungsten strength with copper conductivity. Those characteristics shape how we approach punching — from tool and parameter selection to work-holding and coolant.
If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.
CNC Punching Tolerances & Surface Finish
Punched Tungsten Copper holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
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.
CNC Punching Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Tungsten Copper 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.
Secondary Operations & Finishing
We complete Tungsten Copper 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.
Design Tips for CNC Punching Tungsten Copper
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 Tungsten Copper. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Punching Tungsten Copper
CNC Punching of Tungsten Copper supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.
How to Order CNC Punching Tungsten Copper

What We Need to Quote CNC Punching Tungsten Copper
- 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 Tungsten Copper 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 is CNC Punching Tungsten Copper and how is it done?
CNC Punching Tungsten Copper refers to cNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. Applied to Tungsten Copper — combines tungsten strength with copper conductivity — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What tolerances can you hold for CNC Punching Tungsten Copper?
Achievable tolerances for Tungsten Copper punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
How clean are the edges produced by CNC Punching on Tungsten Copper?
Punched Tungsten Copper edges are clean when punch/die clearance is correct; we set clearance to the gauge and can add deburring if specified.
Does CNC Punching Tungsten Copper require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
