Published typical values for C36000. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
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 Cylindrical Grinding
C260 Brass behaves predictably under CNC Cylindrical Grinding once parameters are dialled in: machinability is excellent (free-machining); fast speeds, clean finish, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of C260 Brass run consistently from one batch to the next.
Achievable Tolerances for CNC Cylindrical 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.
CNC Cylindrical 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 C260 Brass part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Secondary Operations & Finishing
Finished C260 Brass 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.
Design Tips for CNC Cylindrical Grinding C260 Brass
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 C260 Brass efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Cylindrical 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.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Why C260 Brass?
C260 Brass is chosen when a part needs what this grade offers — it is free-machining with good conductivity. We confirm the grade and any temper or heat-treat condition with you before machining.
Applications of CNC Cylindrical Grinding C260 Brass
Customers order CNC Cylindrical Grinding C260 Brass 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 Cylindrical Grinding C260 Brass
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.
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 Cylindrical 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.
