| ■Recommended Cutting Conditions |
| 1. For stable machining performance use rigid, high-precision machines and holders. |
2. Use air blow when dry machining. 3. Use wet machining for stainless steel, heat resistant alloy, and titanium alloy applications. 4. If chattering is a pr oblem, reduce the spindle speed and feed rate indicated in the table below by the same ratio, or reduce the depth of cut. 5. This series is not recommended for groove milling. 6. If the machine cannot achieve the recommended spindle speed, please use the max. spindle speed available.
