VT machining provides CNC Laser Cutting Tungsten for customers who need accurate, repeatable Tungsten components. Because Tungsten is extreme hardness, density and heat resistance, we adapt the process to suit — controlling the variables that matter for this alloy.

CNC Laser Cutting Capability for Tungsten

Published typical values for Pure W / W-Ni-Fe. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Conventional cutting is not on the table for pure tungsten. Features are wire-EDM cut and ground; expect longer lead time than any other metal on the list.
How CNC Laser 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.
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 Laser 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.
CNC Laser Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Tungsten 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 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 Laser Cutting Tungsten
A few design choices make a real difference to cost and quality. 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 Laser 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.
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.
Working with Tungsten
Tungsten offers a useful combination of properties: it is extreme hardness, density and heat resistance. Those characteristics shape how we approach laser cutting — 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.
Applications of CNC Laser Cutting Tungsten
CNC Laser Cutting of Tungsten 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 Laser Cutting Tungsten
Ordering Tungsten parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.

What We Need to Quote CNC Laser 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.
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.

Request a QuoteFrequently Asked Questions
Can VT machining make custom Tungsten parts to my drawing?
Yes. Tungsten Tungsten cutting is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What tolerances can you hold for CNC Laser 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.
What surface finish is achievable on Tungsten with CNC Laser Cutting?
Laser cutting leaves a clean cut face on Tungsten with a small heat-affected zone; most parts need little secondary finishing.
What is the typical lead time and minimum order for CNC Laser Cutting Tungsten?
CNC Laser 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.
Does CNC Laser 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 CNC Laser Cutting Tungsten and how is it done?
CNC Laser Cutting Tungsten refers to cNC fiber laser cutting follows a programmed path to cut sheet and plate with a clean, narrow kerf. 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.
