■ 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. In rear cases, chattering may occur in early milling stages, dissipating after 2m of cutting.
