VT machining specialises in CNC Saw Cutting C122 Copper. Because C122 Copper is excellent electrical and thermal conductivity, and its machinability is moderate; gummy, so sharp tooling and coolant are used, we plan each job around the grade to protect accuracy and surface quality.
CNC Saw Cutting Capability for C122 Copper
- Excellent conductivity

| Grades we run | C10100 OFE, C10200 OF, C11000 ETP, C14500 tellurium copper |
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 C122 Copper with CNC Saw Cutting
C122 Copper behaves predictably under CNC Saw Cutting once parameters are dialled in: machinability is moderate; gummy, so sharp tooling and coolant are used, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of C122 Copper run consistently from one batch to the next.
Achievable Tolerances for CNC Saw Cutting C122 Copper
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 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.
Design Tips for CNC Saw Cutting C122 Copper
We are happy to suggest design tweaks that improve manufacturability. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed C122 Copper. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Finished C122 Copper 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 Saw Cutting 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 C122 Copper part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Why C122 Copper?
C122 Copper is chosen when a part needs what this grade offers — it is excellent electrical and thermal conductivity. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Saw Cutting Tolerances & Surface Finish
Formed C122 Copper holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
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.
Applications of CNC Saw Cutting C122 Copper
Customers order CNC Saw Cutting C122 Copper 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 Saw Cutting C122 Copper
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 C122 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 Saw Cutting C122 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 C122 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.
