Recommended Cutting Conditions 1. Use a precision machine 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 as necessary as equipment performance and other conditions may vary. 5. Values shown in the table of conditions are guidelines. Adjust the actual cutting conditions to the desired machined surface quality.
