CNC Routing Hard Alloys from VT machining delivers precision Hard Alloys parts produced to your exact drawing. CNC routing cuts profiles and openings in sheet and plate at high feed rates with a rotating router bit, and we tune every parameter to the behaviour of Hard Alloys, which is wear-resistant carbide and hardened tool materials.
CNC Routing Capability for Hard Alloys
- High-feed profiling
- Sheet and plate stock
- Nested-part layouts
- Edge tolerance ±0.1 mm
Hard Alloys material properties, finishing options and grade notes are on our CNC Milling Hard Alloys page.
How CNC Routing Hard Alloys Works
Rotating multi-flute cutters remove material as the Hard Alloys workpiece is driven through programmed tool paths on 3-, 4- or 5-axis machining centres. Climb milling, step-over and depth-of-cut are set so chip load stays in the ideal band for the alloy.
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 Routing Hard Alloys
| 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 Routing Tolerances & Surface Finish
For CNC Routing, 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.
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 Routing Hard Alloys
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 Hard Alloys. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Routing Hard Alloys
Hard Alloys parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
Typical Hard Alloys Parts for CNC Routing
Illustrative examples of CNC Routing Hard Alloys parts and the callouts that usually drive the process plan. They show the kind of work that fits this process; they are not specific customer orders.

What We Need to Quote CNC Routing Hard Alloys
- 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 Hard Alloys 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.

Does CNC Routing Hard Alloys require dedicated tooling?
Most Hard Alloys machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Can VT machining make custom Hard Alloys parts to my drawing?
Yes. Hard Alloys machining 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 material thickness or size range suits CNC Routing Hard Alloys?
We machine Hard Alloys across a broad size range; share your part envelope for confirmation.
Which industries use CNC Routing Hard Alloys parts?
CNC Routing Hard Alloys parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Hard Alloys components are required.
