Machining C145 Tellurium Copper with CNC Cylindrical Grinding
The machinability of C145 Tellurium Copper is excellent (free-machining copper) with high conductivity retained. For CNC Cylindrical Grinding we select tooling, feeds, speeds and coolant to match, keeping the C145 Tellurium Copper workpiece stable and the result accurate.
Because we machine C145 Tellurium Copper regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Cylindrical Grinding C145 Tellurium 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.
Design Tips for CNC Cylindrical Grinding C145 Tellurium Copper
A few design choices make a real difference to cost and quality. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on C145 Tellurium Copper efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Cylindrical Grinding Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on C145 Tellurium 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 Cylindrical Grinding Tolerances & Surface Finish
Ground C145 Tellurium 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.
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.

What We Need to Quote CNC Cylindrical Grinding C145 Tellurium 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 C145 Tellurium 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.
