CNC Deburring Tungsten from VT machining delivers precision Tungsten parts produced to your exact drawing. Automated deburring removes sharp edges and burrs for safe handling and consistent edge quality, and we tune every parameter to the behaviour of Tungsten, which is extreme hardness, density and heat resistance.

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 Deburring Tungsten Works
Abrasive media or tooling refine the Tungsten surface in controlled stages, removing the previous step's marks until the target roughness and edge condition are reached.
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 Deburring Tungsten
| Feature | Standard | Precision |
|---|---|---|
| Surface roughness | Ra 0.8 µm | Ra 0.05 µm |
| Edge break | 0.1–0.3 mm | 0.05 ±0.02 mm |
| Material removed | 0.02 mm | 0.005 mm |
| Bore roundness after honing | 0.005 mm | 0.002 mm |
| Cross-hatch angle | 45° ±10° | 45° ±5° |
| Cosmetic grade | uniform satin | mirror, no visible lines |
| Masking of datum faces | on request | standard |
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 Deburring Tungsten
A few design choices make a real difference to cost and quality. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish Tungsten efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Deburring Tolerances & Surface Finish
Finishing brings Tungsten to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
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 finishing — 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.
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.
CNC Deburring 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.
Applications of CNC Deburring Tungsten
CNC Deburring 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 Deburring 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.
Parts We Have Run in Tungsten
Three representative CNC Deburring Tungsten jobs, with the callouts that actually drove the process plan. Yours will differ — these are here so you can judge whether your part is in our range before you spend time on an RFQ.

What We Need to Quote CNC Deburring 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.
