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.※(3) Adjust by setting ae to (3 to 5)×(ap)×(cutting depth ratio). When performing finishing processing, calculate the theoretical cusp height and set accordingly.【切込み設定例】EPDBE2020-10-ATHの工具で焼入れ鋼（50HRC）をリブ溝等高線切削する場合、nmin-116,065 16,065 16,065 16,065 16,065 16,065 15,173 14,280 14,280 12,495 10,710 15,725 15,725 14,153 14,153 14,153 12,580 13,600 13,600 13,600 13,600 12,240 12,240 12,240 10,880 11,688 10,519 10,519 9,350 9,775 9,775 9,775 9,775 8,798 8,798 8,798 8,798 7,820 7,820 7,650 7,650 6,885 6,885 7,650 7,225 6,800 6,120 nmin-117,010 17,010 17,010 17,010 17,010 17,010 16,065 15,120 15,120 13,230 11,340 16,650 16,650 14,985 14,985 14,985 13,320 14,400 14,400 14,400 14,400 12,960 12,960 12,960 11,520 12,375 11,138 11,138 9,900 10,350 10,350 10,350 10,350 9,315 9,315 9,315 9,315 8,280 8,280 8,100 8,100 7,290 7,290 8,100 7,650 7,200 6,480 nmin-118,900 18,900 18,900 18,900 18,900 18,900 17,850 16,800 16,800 14,700 12,600 18,500 18,500 16,650 16,650 16,650 14,800 16,000 16,000 16,000 16,000 14,400 14,400 14,400 12,800 13,750 12,375 12,375 11,000 11,500 11,500 11,500 11,500 10,350 10,350 10,350 10,350 9,200 9,200 9,000 9,000 8,100 8,100 9,000 8,500 8,000 7,200 nmin-122,680 22,680 22,680 22,680 22,680 22,680 21,420 20,160 20,160 17,640 15,120 22,200 22,200 19,980 19,980 19,980 17,760 19,200 19,200 19,200 19,200 17,280 17,280 17,280 15,360 16,500 14,850 14,850 13,200 13,800 13,800 13,800 13,800 12,420 12,420 12,420 12,420 11,040 11,040 10,800 10,800 9,720 9,720 10,800 10,200 9,600 8,640 ap(mm)【Note】1銅0.08 0.08 0.08 0.08 0.06 0.05 0.042 0.035 0.015 0.012 0.01 0.25 0.17 0.1 0.08 0.065 0.044 0.3 0.21 0.21 0.21 0.12 0.08 0.08 0.064 0.24 0.14 0.09 0.072 0.4 0.32 0.28 0.28 0.16 0.16 0.1 0.1 0.08 0.07 0.35 0.35 0.2 0.2 0.6 0.5 0.42 0.15 1.252.51.51.753.52.5切込み=0.14（ap）×0.65（焼入れ鋼グループ5の切込み比率）×0.8（閉鎖域の切削）=0.073mmlength(mm)12131416182022253035406101520253081013162025303515253545101316202530354045502025304012203050Cutting depth setting example: When cutting rib groove contours in hardened steel (50HRC) using an EPDBE2020-10-ATH tool:Cutting depth = 0.14 (ap) × 0.65 (cutting depth factor for Group 5 hardened steel) × 0.8 (for closed-area cutting) = 0.073mm23431256243ステンレス鋼・工具鋼プリハードン鋼Pre-hardened Steels（35〜45HRC）90%80%送り速度回転数回転数【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。（180〜250HB）mm/min1,814 1,814 1,814 1,633 1,633 1,633 1,457 1,371 1,371 1,129 968 2,700 2,700 2,186 2,186 1,967 1,836 2,880 2,880 2,880 2,592 2,333 2,333 2,333 1,958 2,820 2,280 2,280 1,918 2,760 2,760 2,760 2,760 2,236 2,236 2,236 2,236 1,877 1,877 2,592 2,592 2,333 2,100 3,024 2,652 2,304 1,866 mm/min1,512 1,512 1,512 1,361 1,361 1,361 1,214 1,142 1,142 941 806 2,250 2,250 1,822 1,822 1,639 1,530 2,400 2,400 2,400 2,160 1,944 1,944 1,944 1,632 2,350 1,900 1,900 1,598 2,300 2,300 2,300 2,300 1,863 1,863 1,863 1,863 1,564 1,564 2,160 2,160 1,944 1,750 2,520 2,210 1,920 1,555 炭素鋼・合金鋼120%100%回転数送り速度回転数送り速度（25〜35HRC）mm/min1,361 1,361 1,361 1,225 1,225 1,225 1,092 1,028 1,028 847 726 2,025 2,025 1,640 1,640 1,475 1,377 2,160 2,160 2,160 1,944 1,750 1,750 1,750 1,469 2,115 1,710 1,710 1,438 2,070 2,070 2,070 2,070 1,677 1,677 1,677 1,677 1,408 1,408 1,944 1,944 1,750 1,575 2,268 1,989 1,728 1,400 （45〜55HRC）（55〜65HRC）mm/min1,157 1,157 1,157 1,041 1,041 1,041 929 874 874 720 617 1,688 1,688 1,367 1,367 1,229 1,148 1,822 1,822 1,822 1,640 1,476 1,476 1,476 1,239 1,763 1,425 1,425 1,199 1,760 1,760 1,760 1,760 1,425 1,425 1,425 1,425 1,196 1,196 1,530 1,530 1,377 1,239 1,890 1,658 1,360 1,102 56焼入れ鋼65%送り速度回転数送り速度回転数焼入れ鋼60%送り速度推奨領域 Recommended range被削材切込み比率 Ratio to standard depth of cutボール半径REBall radius首下長LUUnder neck外径DCTool dia.(mm)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.
