1. Use a rigid and precise machine and holder. 2. When machining carbon steels or hardened steels, using MQL(Minimum Quantity Lubrication / mist coolant) is recommended. 3. The above condition shows an approximate standard for contouring operation(side milling) with a low machining load. If abnormal cutting sounds, vibration or chattering occur depending on the machining shape, cutting amount, rigidity of the machine or work holding condition, etc., please adjust the speed, feed and the depth of cut. 4. Adjust the speed, feed rate, and depth of cut if chattering, vibration or abnormal grinding sounds occur. 5. Helical or ramp milling is recommended during the approach of a Z cut. 6. When using a tool with a diameter of φ 0.5 or less, or L/D (aspect ratio) is greater than 10, high loads can cause tool breakage. Therefore, adjust the cutting conditions based on the machining situation. 7. When RPM are insufficient, please reduce the RPM and feed rates at same ratio as listed above.
