Machining C145 Tellurium Copper with CNC Drilling
The machinability of C145 Tellurium Copper is excellent (free-machining copper) with high conductivity retained. For CNC Drilling 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 Drilling C145 Tellurium Copper
| Feature | Standard | Precision |
|---|---|---|
| Linear dimension (< 100 mm) | ±0.05 mm | ±0.010 mm |
| Linear dimension (100–300 mm) | ±0.10 mm | ±0.025 mm |
| Hole diameter (reamed) | H9 | H7 |
| True position of hole pattern | ±0.10 mm | ±0.025 mm |
| Flatness over 100 mm | 0.05 mm | 0.015 mm |
| Perpendicularity | 0.10 mm | 0.020 mm |
| Surface finish, as machined | Ra 1.6 µm | Ra 0.4 µm |
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 Drilling 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.
Why C145 Tellurium Copper?
Specifying C145 Tellurium Copper for CNC Drilling C145 Tellurium Copper is usually about its properties: free-machining with high conductivity. Tell us the condition you need and we machine to 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.
Design Tips for CNC Drilling C145 Tellurium 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 C145 Tellurium Copper. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
We complete C145 Tellurium 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.
