Note 1) When cutting austenitic stainless steel, the use of water-soluble cutting fluid is especially effective. Note 2) If the depth of cut is smaller than this table, feed rate can be increased. I Note 3) When drilling, please set the feed rate at 1/3 or below of the above value. Note 4) 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. I085
