The above milling condition is a guideline for L/D ratio 1.25 and 1.5. 2. Use a rigid and precise machine and holder. 3. The rotational speed is calculated by the median of the recommended cutting speed. Adjustments may be necessary depending on the rigidity or the workpiece, fixture, and machine. 4. Please use a suitable fluid with high smoke retardant properties. 5. During dry (no fluid) milling, please use air blow to remove chips from the milling area and to eliminate chip packing.
6. Please use water-soluble coolant when machining stainless steel and titanium alloy. 7. Reduce speed and feed as well as depth of cut when high precision is required.
