VT machining specialises in CNC Engraving Tungsten Carbide. Because Tungsten Carbide is extreme hardness for tooling and wear parts, and its machinability is machined almost exclusively by grinding and EDM, we plan each job around the grade to protect accuracy and surface quality.
CNC Engraving Capability for Tungsten Carbide
- Extreme hardness (HRA 89–94)
- Ground/EDM only

| Grades we run | YG6, YG8, YG15 (K10–K30), D2, H13, M2, SKD11 |
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 Engraving
When machining 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 Engraving Tungsten Carbide
| Feature | Standard | Precision |
|---|---|---|
| Linear dimension (< 100 mm) | ±0.05 mm | ±0.010 mm |
| Linear dimension (100–300 mm) | ±0.10 mm | ±0.025 mm |
| Hole diameter (reamed) | H9 | H7 |
| True position of hole pattern | ±0.10 mm | ±0.025 mm |
| Flatness over 100 mm | 0.05 mm | 0.015 mm |
| Perpendicularity | 0.10 mm | 0.020 mm |
| Surface finish, as machined | 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 Engraving 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.
CNC Engraving Tolerances & Surface Finish
For CNC Engraving, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
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.
Design Tips for CNC Engraving Tungsten Carbide
Small design adjustments often cut cost and lead time. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in Tungsten Carbide. If you send your model early, we will return practical DFM feedback before you commit to production.
Why Tungsten Carbide?
Customers select Tungsten Carbide for CNC Engraving because it is extreme hardness for tooling and wear parts. We handle grade verification and any required heat treatment or finishing.
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 Engraving 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.

What We Need to Quote CNC Engraving 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.
