CNC Cylindrical Grinding Nickel Silver from VT machining delivers precision Nickel Silver parts produced to your exact drawing. Cylindrical grinding finishes outer diameters of rotational parts to precise size and roundness, and we tune every parameter to the behaviour of Nickel Silver, which is corrosion resistant with a bright silver-white finish.

How CNC Cylindrical Grinding Nickel Silver Works
An abrasive wheel removes a fine, controlled layer from the Nickel Silver 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.
Achievable Tolerances for CNC Cylindrical Grinding Nickel Silver
| Feature | Standard | Precision |
|---|---|---|
| Size (OD, ID, thickness) | ±0.005 mm | ±0.002 mm |
| Flatness over 100 mm | 0.010 mm | 0.003 mm |
| Parallelism | 0.010 mm | 0.003 mm |
| Roundness | 0.005 mm | 0.002 mm |
| Squareness | 0.010 mm | 0.005 mm |
| Surface finish | Ra 0.4 µm | Ra 0.1 µm |
| Workpiece hardness | up to 62 HRC | up to 65 HRC |
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 Cylindrical Grinding Tolerances & Surface Finish
Ground Nickel Silver 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.
Design Tips for CNC Cylindrical Grinding Nickel Silver
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 Nickel Silver efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Cylindrical Grinding Nickel Silver
Customers order CNC Cylindrical Grinding Nickel Silver 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.

What We Need to Quote CNC Cylindrical Grinding Nickel Silver
- 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 Nickel Silver 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
How clean are the edges produced by CNC Cylindrical Grinding on Nickel Silver?
Machined Nickel Silver edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What is CNC Cylindrical Grinding Nickel Silver and how is it done?
CNC Cylindrical Grinding Nickel Silver refers to cylindrical grinding finishes outer diameters of rotational parts to precise size and roundness. Applied to Nickel Silver — corrosion resistant with a bright silver-white finish — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What material thickness or size range suits CNC Cylindrical Grinding Nickel Silver?
We machine Nickel Silver across a broad size range; share your part envelope for confirmation.
Does CNC Cylindrical Grinding Nickel Silver require dedicated tooling?
Most Nickel Silver grinding work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
