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 some cases, chattering may occur in early stages of milling but will cease after 2m of cutting.
5. If chatter is a problem, reduce the spindle speed and feed rate indicated in the table below by the same ratio, or reduce the depth of cut. 6. If the machine cannot achieve the recommended spindle speed, please use the maximum spindle speed available. Side Milling
