Note 2) In case of slotting with over 3 mm endmill, please reduce revolution to 50 ─ 70% of above value, and reduce feed rate to 40 ─60% of above value. Note 3) If the rigidity of the machine or the work material installation is very low, or chattering is generated, please reduce the revolution and the feed rate proportionately. I061
