Nothing much — this is the easiest metal in the shop. Worth asking about if a copper or bronze part is cost-driven rather than conductivity-driven.
Machining C260 Brass with CNC Centerless Grinding
When grinding C260 Brass, machinability is excellent (free-machining); fast speeds, clean finish. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for C260 Brass mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Centerless Grinding C260 Brass
| 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.
Secondary Operations & Finishing
Most C260 Brass 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.
CNC Centerless Grinding Tolerances & Surface Finish
Ground C260 Brass 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 Centerless Grinding C260 Brass
Small design adjustments often cut cost and lead time. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on C260 Brass efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Centerless Grinding 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.
Why C260 Brass?
Customers select C260 Brass for CNC Centerless Grinding because it is free-machining with good conductivity. We handle grade verification and any required heat treatment or finishing.

Finishing Options for C260 Brass
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Nickel plate | 5–15 µm | Hard, bright, corrosion resistant |
| Chrome plate | 0.3–1 µm | Decorative, over nickel |
| Clear lacquer | 10–20 µm | Stops the natural tarnish |
| Tin plate | 3–15 µm | Solderable contacts |
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Centerless Grinding C260 Brass
- 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 C260 Brass 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.

Request a QuoteFrequently Asked Questions
How clean are the edges produced by CNC Centerless Grinding on C260 Brass?
Machined C260 Brass edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Why is C260 Brass a good choice for CNC Centerless Grinding?
C260 Brass is free-machining with good conductivity, which makes it well suited to CNC Centerless Grinding. We tune the process to the alloy so the finished C260 Brass grinding part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Centerless Grinding C260 Brass?
Achievable tolerances for C260 Brass 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.
Does CNC Centerless Grinding C260 Brass require dedicated tooling?
Most C260 Brass grinding work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
