5-axis PEEK machining is used for complex aerospace and medical components where the material's high temperature resistance and biocompatibility are combined with sophisticated geometries.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm |
| Surface Finish | Ra 0.8-3.2 μm |
| Cutting Speed | 100-250 m/min |
| Feed Rate | 0.05-0.15 mm/tooth |
| Tooling Recommendations | Uncoated carbide with polished flutes. O-flute end mills. Sharp ball nose for contours. |
