CNC Polishing Nickel Silver from VT machining delivers precision Nickel Silver parts produced to your exact drawing. CNC polishing refines surfaces to a smooth, reflective finish for cosmetic and functional needs, and we tune every parameter to the behaviour of Nickel Silver, which is corrosion resistant with a bright silver-white finish.

Published typical values for C75200 (65-18). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
It is bought for its colour as often as its properties, so cosmetic faces are masked through deburring and handled in gloves from the machine onward.
How CNC Polishing Nickel Silver Works
Abrasive media or tooling refine the Nickel Silver surface in controlled stages, removing the previous step's marks until the target roughness and edge condition are reached.
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 Polishing Nickel Silver
| Feature | Standard | Precision |
|---|---|---|
| Surface roughness | Ra 0.8 µm | Ra 0.05 µm |
| Edge break | 0.1–0.3 mm | 0.05 ±0.02 mm |
| Material removed | 0.02 mm | 0.005 mm |
| Bore roundness after honing | 0.005 mm | 0.002 mm |
| Cross-hatch angle | 45° ±10° | 45° ±5° |
| Cosmetic grade | uniform satin | mirror, no visible lines |
| Masking of datum faces | on request | standard |
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.
Secondary Operations & Finishing
Finished Nickel Silver 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 Polishing Tolerances & Surface Finish
Finishing brings Nickel Silver to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
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.
CNC Polishing 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 Nickel Silver part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Design Tips for CNC Polishing Nickel Silver
We are happy to suggest design tweaks that improve manufacturability. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish Nickel Silver efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Nickel Silver
As a material, Nickel Silver is corrosion resistant with a bright silver-white finish. 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.
Applications of CNC Polishing Nickel Silver
Customers order CNC Polishing 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.
How to Order CNC Polishing Nickel Silver
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.
Parts We Have Run in Nickel Silver
Three representative CNC Polishing Nickel Silver jobs, with the callouts that actually drove the process plan. Yours will differ — these are here so you can judge whether your part is in our range before you spend time on an RFQ.

What We Need to Quote CNC Polishing 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.
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.
