Turning copper is challenging due to its extreme ductility and tendency to produce long, unmanageable chips. Specialized chip-breaking techniques are essential.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.01 mm (±0.0004") |
| Surface Finish | Ra 0.4-1.6 μm |
| Cutting Speed | 150-400 m/min |
| Feed Rate | 0.10-0.25 mm/rev |
| Tooling Recommendations | PCD inserts for best finish. Sharp uncoated carbide with chip-breaking geometry. Avoid TiAlN-coated tools. |
Use sharp positive-rake inserts with chip breaker
Higher feeds help chips break
Keep tool extremely sharp — dull tools smear
Compressed air instead of flood coolant for chip management
