How CNC Plasma Cutting Tungsten Works
A focused fibre-laser beam melts and blows material from the Tungsten sheet along the programmed contour. Power, focal position, nozzle stand-off and assist-gas pressure are tuned to the alloy and thickness for a clean, square edge.
Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.
Achievable Tolerances for CNC Plasma Cutting Tungsten
| Feature | Standard | Precision |
|---|---|---|
| Contour dimension | ±0.10 mm | ±0.05 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Kerf width | 0.20 mm | 0.10 mm |
| Squareness of cut edge | 0.5° | 0.2° |
| Heat-affected zone | 0.15 mm | 0.05 mm (N₂ assist) |
| Minimum hole diameter | 1.2 × thickness | 1.0 × thickness |
| Edge condition | light dross | burr-free, N₂ cut |
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.
Design Tips for CNC Plasma Cutting Tungsten
We are happy to suggest design tweaks that improve manufacturability. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on Tungsten. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Plasma Cutting Tolerances & Surface Finish
Laser-cut Tungsten holds contour tolerances around ±0.05 mm depending on thickness, with a narrow kerf and a clean, near burr-free edge.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Applications of CNC Plasma Cutting Tungsten

What We Need to Quote CNC Plasma Cutting Tungsten
- 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 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.

Request a QuoteFrequently Asked Questions
What surface finish is achievable on Tungsten with CNC Plasma Cutting?
Laser cutting leaves a clean cut face on Tungsten with a small heat-affected zone; most parts need little secondary finishing.
What is CNC Plasma Cutting Tungsten and how is it done?
CNC Plasma Cutting Tungsten refers to cNC plasma cutting uses an ionized gas jet to sever thicker conductive plate at high speed. Applied to Tungsten — extreme hardness, density and heat resistance — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Does CNC Plasma Cutting Tungsten require dedicated tooling?
Most Tungsten cutting work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Plasma Cutting Tungsten?
CNC Plasma Cutting prototypes for Tungsten can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Plasma Cutting Tungsten?
Achievable tolerances for Tungsten cutting depend on the alloy, geometry and feature size. Laser cutting holds contour tolerances to around ±0.05 mm depending on thickness. Exact figures are confirmed against your drawing callouts.
