Aluminum 6061 is ideal for CNC turning, producing excellent chip formation and surface finish at high speeds. It is the most commonly turned aluminum alloy.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.005 mm (±0.0002") |
| Surface Finish | Ra 0.2-0.8 μm |
| Cutting Speed | 300-600 m/min |
| Feed Rate | 0.08-0.25 mm/rev |
| Tooling Recommendations | Carbide inserts with sharp edge, positive rake. PCD for high-volume. Cermet for finishing. |
Use sharp positive-rake inserts
High cutting speeds (300+ m/min) for best finish
Chip breakers may not be needed — chips break naturally
Light finishing passes for mirror finish
Shafts and spindles
Bushings and spacers
Threaded fittings
Knobs and handles
Pneumatic cylinder bodies
