4.5-Axis CNC Machining for Brass C360 (Free-Cutting Brass)
4.5-axis machining of brass is relatively rare since most brass parts are simpler geometries suited to turning. When needed, brass machines exceptionally well in 4.5-axis configurations.
Recommended Machining Parameters
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm |
| Surface Finish | Ra 0.2-0.4 μm |
| Cutting Speed | 200-500 m/min |
| Feed Rate | 0.08-0.20 mm/tooth |
| Tooling Recommendations | Carbide ball nose end mills. PCD for mirror finish. Standard HSS for prototyping. |
