Turning 304 stainless requires constant chip engagement and sharp tooling. The material's work-hardening tendency makes it essential to never let the tool dwell or rub.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.01 mm (±0.0004") |
| Surface Finish | Ra 0.8-3.2 μm |
| Cutting Speed | 100-200 m/min |
| Feed Rate | 0.10-0.25 mm/rev |
| Tooling Recommendations | Carbide inserts grade M20-M30 with TiAlN coating. Use chip-breaking geometry. Cermet for finishing. |
Never reduce feed below 0.05 mm/rev — the tool must cut, not rub
Use chip-breaking inserts always
High-pressure coolant directed at cutting zone
Replace inserts frequently — dull tools cause work-hardening
