VT machining provides CNC Press Brake Forming Tungsten Carbide for customers who need accurate, repeatable Tungsten Carbide components. The machinability of Tungsten Carbide is machined almost exclusively by grinding and EDM, so we set the operation up specifically for this grade.

Published typical values for WC-Co (YG8 / K20). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Everything is done by grinding, wire EDM or sinker EDM. Design in a small corner radius wherever possible — a true sharp internal corner doubles the EDM time.
Machining Tungsten Carbide with CNC Press Brake Forming
When forming Tungsten Carbide, machinability is machined almost exclusively by grinding and EDM. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for Tungsten Carbide mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Press Brake Forming Tungsten Carbide
| 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.
Design Tips for CNC Press Brake Forming Tungsten Carbide
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 Carbide. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Press Brake Forming Tolerances & Surface Finish
Formed Tungsten Carbide holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
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.
Why Tungsten Carbide?
Customers select Tungsten Carbide for CNC Press Brake Forming because it is extreme hardness for tooling and wear parts. We handle grade verification and any required heat treatment or finishing.
CNC Press Brake Forming Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Secondary Operations & Finishing
Most Tungsten Carbide parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Applications of CNC Press Brake Forming Tungsten Carbide
Tungsten Carbide parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Press Brake Forming Tungsten Carbide

What We Need to Quote CNC Press Brake Forming Tungsten Carbide
- 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 Carbide 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 Press Brake Forming on Tungsten Carbide?
Machined Tungsten Carbide edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on Tungsten Carbide with CNC Press Brake Forming?
Surface finish on Tungsten Carbide is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Press Brake Forming Tungsten Carbide require dedicated tooling?
Most Tungsten Carbide 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 Carbide parts to my drawing?
Yes. Tungsten Carbide Tungsten Carbide 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.
