Turning PEEK requires managing heat to prevent changes in crystallinity and dimensional instability. Sharp tooling and appropriate speeds produce excellent results.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm (±0.001") |
| Surface Finish | Ra 0.8-3.2 μm |
| Cutting Speed | 150-300 m/min |
| Feed Rate | 0.05-0.15 mm/rev |
| Tooling Recommendations | Sharp uncoated carbide or PCD. Positive rake angle. Polished insert face to reduce friction. |
