Notes: • When cutting at a large depth of cut or a large cutting width, the cutting speed (v c) and feed (fz) should be set to the lower side of the values
shown in the above table.
• Dry cutting (or air-blowing) is generally recommended. However, when chips tend to excessively adhere to the cutting edges such as when
machining stainless steel, use a water soluble cutting fluid. In this case, use AH140 grade at speeds lower than v c = 400 SFM.
• When wet machining mild steels, carbon steels, and alloy steels, use T3130 at lower cutting conditions.
• TAW13 type TAC mills can not be used for axial-feed cutting such as ramping, plunging, and drilling.
