CNC Milling for Brass C360 (Free-Cutting Brass)
Brass C360 is a dream material for CNC milling. It machines at extremely high speeds with excellent chip formation, minimal tool wear, and superb surface finish. It is the benchmark for machinability.
Recommended Machining Parameters
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm (±0.0008") |
| Surface Finish | Ra 0.2-0.8 μm |
| Cutting Speed | 200-500 m/min (SFM 650-1650) |
| Feed Rate | 0.08-0.20 mm/tooth |
| Tooling Recommendations | Carbide or HSS end mills, 2-3 flutes. Uncoated tools work well. PCD for ultra-high volume. |
