Recommended Cutting Conditions 1. Use a machine with high rigidity for stable cutting. 2. Non-water soluble cutting oil is recommended. Supply as a mist or external coolant. Take fire prevention precautions to avoid fire hazards caused by sparks igniting during machining or tool breakage. 3. Shorten overhang as much as possible. 4. Adjust cutting conditions according to actual conditions as machine rigidity and other conditions may vary. 5. Depths of cut shown in the table of conditions are maximum depths. Adjust the actual depth of cut to the desired machined surface roughness.
