Note: • When ap and ae are the higher limit, use the lower limit of feed rate value shown above.
• The maximum depth of cut for these TAC mills are 3.0 in. For milling the work material with rough outer skin or
many interrupted areas, reduce the feed per tooth and the maximum depth of cut to 1/2 to 2/3 of the values
shown in the table.
• The cutting condition is limited by machine rigidity and power. The operation should start at half of the
recommended speed. The amount of vibration and machine power should then be evaluated before
increasing the cutting speed.
• When wet machining mild steels, carbon steels and alloy steels, use T3130 at lower cutting conditions.
• This TAC mill is not designed to cope with the centrifugal force and dynamic balance at high speeds over 3300
SFM. Therefore, the cutting speed in the outer diameter of the mill should not exceed 3300 SFM.  : Stocked items.
