※（１）基本切込みは被削材グル−プ1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。
※（２）リブ加工や止まり溝など、切りくずがつまりやすい切削の場合、切込み設定は基本切込みに切込み比率をかけて算出した切込み量 を、さらにその80％まで小さくして使用してください。
【切込み設定例】EPDBPE2020-25-09-ATHの工具で焼入れ鋼（50HRC）をリブ溝等高線切削する場合、
切込み=0.07（基本切込み）×0.65（焼入れ鋼グループ4の切込み比率）×0.8（閉鎖域の切削）=0.036
※(1) Standard cutting depth is shown as the criteria for Group 1 workpieces. For other groups, adjust the cutting depth according to the cutting depth factors in the above table.
※(2) When performing cutting where cutting chips may cause clogging, such as for rib processing, blind grooves, etc., cutting depth setting should be set by multiplying a cutting depth factor to calculate the cutting depth amount, and this amount should then be reduced to 80% of the calculated value.
Cutting depth setting example: When cutting rib groove contours in pre-harden steel (50HRC) using an EPDBPE2020-25-09-ATH tool:
Cutting depth = 0.07 (standard cutting depth) × 0.65 (cutting depth factor for Group 4 pre-harden steel) × 0.8 (for closed-area cutting) = 0.036mm
【注意】
①被削材、加工形状に合わせて、適切なクーラントを使用してください。②この標準切削条件表は切削条件の目安を示すものです。実際の加工では加工形状、目的、使用機械等により条件を調整してください。
③機械の回転数が足りない場合は、回転数と送り速度を同じ比率で下げてください。
① Use the appropriate coolant for the work material and machining shape.
② These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. 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.

※（１）基本切込みは被削材グル−プ1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。
※（２）リブ加工や止まり溝など、切りくずがつまりやすい切削の場合、切込み設定は基本切込みに切込み比率をかけて算出した切込み量 を、さらにその80％まで小さくして使用してください。
【切込み設定例】EPDBPE2020-25-09-ATHの工具で焼入れ鋼（50HRC）をリブ溝等高線切削する場合、
切込み=0.04（基本切込み）×0.65（焼入れ鋼グループ4の切込み比率）×0.8（閉鎖域の切削）=0.020
※(1) Standard cutting depth is shown as the criteria for Group 1 workpieces. For other groups, adjust the cutting depth according to the cutting depth factors in the above table.
※(2) When performing cutting where cutting chips may cause clogging, such as for rib processing, blind grooves, etc., cutting depth setting should be set by multiplying a cutting depth factor to calculate the cutting depth amount, and this amount should then be reduced to 80% of the calculated value.
Cutting depth setting example: When cutting rib groove contours in pre-harden steel (50HRC) using an EPDBP2020-25-09-TH tool:
Cutting depth = 0.04 (standard cutting depth) × 0.65 (cutting depth factor for Group 4 pre-harden steel) × 0.8 (for closed-area cutting) = 0.020mm
【注意】
①被削材、加工形状に合わせて、適切なクーラントを使用してください。②この標準切削条件表は切削条件の目安を示すものです。実際の加工では加工形状、目的、使用機械等により条件を調整してください。
③機械の回転数が足りない場合は、回転数と送り速度を同じ比率で下げてください。
① Use the appropriate coolant for the work material and machining shape.
② These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. 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.
