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 Boring Tungsten Copper Works
The Tungsten Copper bar or billet rotates in the spindle while single-point tools shape outer diameters, bores, faces, grooves and threads. Constant surface speed control keeps cutting conditions stable from large to small diameters.
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 Boring Tungsten Copper
| Feature | Standard | Precision |
|---|---|---|
| Outside diameter | ±0.05 mm | ±0.005 mm |
| Bore diameter | H9 | H6 |
| Length / shoulder position | ±0.10 mm | ±0.020 mm |
| Concentricity OD to ID | 0.05 mm TIR | 0.010 mm TIR |
| Roundness | 0.02 mm | 0.005 mm |
| Thread class | 6g / 2A | 4h / 3A |
| Surface finish, as turned | Ra 1.6 µm | Ra 0.4 µm |
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 Boring 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.
Design Tips for CNC Boring Tungsten Copper
A few design choices make a real difference to cost and quality. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Tungsten Copper turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
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.
CNC Boring Tolerances & Surface Finish
Turned Tungsten Copper holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
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 Copper
Tungsten Copper offers a useful combination of properties: it is combines tungsten strength with copper conductivity. Those characteristics shape how we approach turning — 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 Boring Tungsten Copper
CNC Boring 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 Boring Tungsten Copper
Ordering Tungsten Copper 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 Boring 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.

Request a QuoteFrequently Asked Questions
How clean are the edges produced by CNC Boring on Tungsten Copper?
Machined Tungsten Copper edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Can VT machining make custom Tungsten Copper parts to my drawing?
Yes. Tungsten Copper Tungsten Copper turning 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 surface finish is achievable on Tungsten Copper with CNC Boring?
Surface finish on Tungsten Copper is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Boring Tungsten Copper require dedicated tooling?
Most Tungsten Copper turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What tolerances can you hold for CNC Boring Tungsten Copper?
Achievable tolerances for Tungsten Copper turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Boring Tungsten Copper?
Turned Tungsten Copper parts are produced from bar or chuck stock across a wide diameter range.
