In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. ③ If the rpm of the machine is low, lower the feed rate also to put the rpm and feed rate in the same ratio.2345623プリハードン鋼Pre-hardened steels90%80%被削材切り込み比率 Ratio to standard depth of cut基本切り込み外径DCTool dia.コーナ半径RECorner radius首下長LUUnder neck※基本切込みは被削材グル−プ2での目安を示しています。その他のグループの場合は、上表の切込み比率を目安に調整して下さい。※Standard cutting depth is shown as the criteria for Group 2 workpieces.
