4.5-Axis CNC Machining for Aluminum 6061-T6
Aluminum 6061 on 4.5-axis machines enables complex aerospace geometries, thin-walled structures, and compound-angle features in a single setup. The material's excellent machinability makes it ideal for 4.5-axis work.
Recommended Machining Parameters
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm |
| Surface Finish | Ra 0.2-0.8 μm |
| Cutting Speed | 200-400 m/min |
| Feed Rate | 0.05-0.15 mm/tooth |
| Tooling Recommendations | Solid carbide ball nose and bull nose end mills. Long-reach tools for deep pockets. Shrink-fit holders for runout control. |
