Published typical values for C11000 ETP. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
It smears rather than cuts. Razor-sharp uncoated tooling and high rake; if the print allows it, C14500 tellurium copper machines four times better at ~90% IACS.
Machining C102 Copper with CNC Punching
The machinability of C102 Copper is moderate; gummy, so sharp tooling and coolant are used. For CNC Punching we select tooling, feeds, speeds and coolant to match, keeping the C102 Copper workpiece stable and the result accurate.
Because we machine C102 Copper regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Punching C102 Copper
| Feature | Standard | Precision |
|---|---|---|
| Hole position across sheet | ±0.15 mm | ±0.10 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Overall blank size | ±0.20 mm | ±0.10 mm |
| Minimum hole | 1.0 × thickness | 0.8 × thickness |
| Hole-to-edge distance | 2.0 × thickness | 1.5 × thickness |
| Burr height | 0.08 mm | 0.03 mm (deburred) |
| Sheet thickness range | 0.5–6.0 mm | 0.5–3.0 mm |
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 Punching Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on C102 Copper parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Secondary Operations & Finishing
We complete C102 Copper components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
CNC Punching Tolerances & Surface Finish
Punched C102 Copper holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Design Tips for CNC Punching C102 Copper
A few design choices make a real difference to cost and quality. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched C102 Copper. If you send your model early, we will return practical DFM feedback before you commit to production.

Finishing Options for C102 Copper
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Tin plate | 3–15 µm | Solderable, prevents oxidation |
| Silver plate | 2–10 µm | Lowest contact resistance for RF and power |
| Nickel underplate | 2–5 µm | Diffusion barrier under tin or gold |
| Gold flash | 0.05–1 µm | Contact surfaces, over nickel |
| 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 Punching C102 Copper
- 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 C102 Copper 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.
