How CNC Press Brake Forming Tungsten Copper Works
The Tungsten Copper blank is bent or formed against tooling under CNC-controlled ram travel and back-gauge positioning. Bend allowance and springback are compensated in the program so finished angles hit the print.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
Achievable Tolerances for CNC Press Brake Forming Tungsten Copper
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 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.
CNC Press Brake Forming Tolerances & Surface Finish
Formed Tungsten Copper holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Design Tips for CNC Press Brake Forming Tungsten Copper
Small design adjustments often cut cost and lead time. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed Tungsten Copper. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Press Brake Forming Tungsten Copper
Tungsten Copper parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC Press Brake Forming 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.

Request a QuoteFrequently Asked Questions
What is CNC Press Brake Forming Tungsten Copper and how is it done?
CNC Press Brake Forming Tungsten Copper refers to press brake forming creates bends and complex profiles with CNC-controlled ram depth and gauging. 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.
Does CNC Press Brake Forming Tungsten Copper require dedicated tooling?
Most Tungsten Copper forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Can VT machining make custom Tungsten Copper parts to my drawing?
Yes. Tungsten Copper forming 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.
Which industries use CNC Press Brake Forming Tungsten Copper parts?
CNC Press Brake Forming Tungsten Copper parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Tungsten Copper components are required.
