Published typical values for C11000 ETP. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.

Machining C122 Copper — what actually causes trouble

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 Drilling

The machinability of C122 Copper is moderate; gummy, so sharp tooling and coolant are used. For CNC Drilling we select tooling, feeds, speeds and coolant to match, keeping the C122 Copper workpiece stable and the result accurate.

Because we machine C122 Copper regularly, proven settings shorten setup and keep quality repeatable across reorders.

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 Drilling C122 Copper

A few design choices make a real difference to cost and quality. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in C122 Copper. If you send your model early, we will return practical DFM feedback before you commit to production.

Why C122 Copper?

Specifying C122 Copper for CNC Drilling C122 Copper is usually about its properties: excellent electrical and thermal conductivity. Tell us the condition you need and we machine to it.

CNC Drilling Quality & Inspection

Consistent quality comes from disciplined process control. Critical dimensions on C122 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.

CNC Drilling Tolerances & Surface Finish

For CNC Drilling, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.

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.

Secondary Operations & Finishing

We complete C122 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.

Applications of CNC Drilling C122 Copper

CNC Drilling of C122 Copper supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

How to Order CNC Drilling C122 Copper

Ordering C122 Copper parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.

What We Need to Quote CNC Drilling 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.
