VT machining provides CNC Cylindrical Grinding C101 Copper for customers who need accurate, repeatable C101 Copper components. The machinability of C101 Copper is moderate; gummy, so sharp tooling and coolant are used, so we set the operation up specifically for this grade.

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 C101 Copper with CNC Cylindrical Grinding
When grinding C101 Copper, machinability is moderate; gummy, so sharp tooling and coolant are used. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for C101 Copper mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Cylindrical Grinding C101 Copper
| 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.
Why C101 Copper?
Customers select C101 Copper for CNC Cylindrical Grinding because it is excellent electrical and thermal conductivity. We handle grade verification and any required heat treatment or finishing.
CNC Cylindrical Grinding Tolerances & Surface Finish
Ground C101 Copper 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 C101 Copper
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 C101 Copper efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Most C101 Copper 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 Cylindrical 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.
Applications of CNC Cylindrical Grinding C101 Copper
C101 Copper parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

Finishing Options for C101 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 Cylindrical Grinding C101 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 C101 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.
