Note 1) Vibration may occur if the rigidity of machine or work material is low. In this case, please reduce the revolution and the feed rate proportionately, or set a lower depth of cut. Note 2) If the depth of cut is smaller, the revolution and the feed rate can be increased. Note 3) For stainless steel, titanium alloy and heat resistant alloy, the use of water-soluble coolant is effective. J025
