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.

Machining Hard Alloys — what actually causes trouble

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.

How CNC Surface Grinding Hard Alloys Works

An abrasive wheel removes a fine, controlled layer from the Hard Alloys part. Wheel specification, dressing interval, infeed and coolant are matched to the alloy's hardness so the surface is not burned or left with residual stress.

Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.

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.

Working with Hard Alloys

As a material, Hard Alloys is wear-resistant carbide and hardened tool materials. Our setup reflects the alloy's machinability so the finished part is accurate and free of avoidable defects.

We verify the exact grade and condition before machining, and traceable mill certs are available on request. We can work to your nominated material source or specification when required.

Secondary Operations & Finishing

Finished Hard Alloys parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.

CNC Surface Grinding Quality & Inspection

We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every Hard Alloys part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.

Design Tips for CNC Surface Grinding Hard Alloys

We are happy to suggest design tweaks that improve manufacturability. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on Hard Alloys efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC Surface Grinding Tolerances & Surface Finish

Ground Hard Alloys reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.

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.

Applications of CNC Surface Grinding Hard Alloys

Customers order CNC Surface Grinding Hard Alloys components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

How to Order CNC Surface Grinding Hard Alloys

Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.

What We Need to Quote CNC Surface Grinding 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.

Frequently Asked Questions

What surface finish is achievable on Hard Alloys with CNC Surface Grinding?

Grinding can take Hard Alloys to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.

Can VT machining make custom Hard Alloys parts to my drawing?

Yes. Hard Alloys Hard Alloys grinding 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.

How clean are the edges produced by CNC Surface Grinding on Hard Alloys?

Machined Hard Alloys edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.

What tolerances can you hold for CNC Surface Grinding Hard Alloys?

Achievable tolerances for Hard Alloys grinding depend on the alloy, geometry and feature size. Grinding routinely holds single-micron tolerances on diameter, flatness and parallelism. Exact figures are confirmed against your drawing callouts.

What is the typical lead time and minimum order for CNC Surface Grinding Hard Alloys?

CNC Surface Grinding prototypes for Hard Alloys can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
