VT machining offers CNC Turning for C102 Copper (UNS C10200 / OF / Cu-OF), typically supplied annealed or H02. Oxygen-free copper, slightly lower purity than C101.
CNC Turning Notes for C102 Copper
On the lathe C102 Copper needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
For estimating, a 100 × 100 × 10 mm block of C102 Copper weighs about 0.89 kg.
Starting Parameters for CNC Turning C102 Copper
| Cutting speed (carbide) | 150-300 m/min |
|---|---|
| Feed | 0.08-0.25 mm/rev |
| Spindle speed, Ø25 mm bar | 1910-3820 rpm |
| Insert / tool class | ISO N — sharp, polished, uncoated or DLC |
| Coolant | Emulsion; very sharp polished tools to avoid smearing |
