316 stainless is the most challenging common stainless to turn. Its gummy nature and extreme work-hardening require aggressive parameters and premium tooling.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.01 mm (±0.0004") |
| Surface Finish | Ra 1.0-3.2 μm |
| Cutting Speed | 80-160 m/min |
| Feed Rate | 0.10-0.25 mm/rev |
| Tooling Recommendations | Premium carbide M25-M35 with nanocomposite coating. Wiper inserts for finishing. Consider whisker-reinforced ceramic for roughing. |
