Conditions must be: ridgid machine circumstances and excellent holders. (shrinking holder) 2. The mentioned standard values based on interpolation milling also in corners. 3. Coolant with MMKS [MQL (mist)] on air blow. 4. When dipping in Z-axis, you have to reduce the feed speed 40% > 60%. 5. The standard values refer to the length l3 od 3×D. For deeper applications please adjust Vc/ap/Vf for the conditions. 6. In order to achieve ideal cutting results you have to consider your local operating conditions. n/Vf 2 rp 3 rp 4 rp 5 rp 6 rp 7 rp 8 rp 9 rp 10 rp 11 rp 12 rp 13 rp 16 rp Material Strength 0.5 0.75 1.0 1.2 1.5 1.5 2.0 2.0 2.0 2.0 3.0 3.0 4.0 N/mm2 1.1 Unalloyed steel < 450 n (rpm) 32,000 21,000 16,000 12,000 11,000 9,000 8,000 7,000 6,000 6,000 5,000 5,000 4,500 1.2 < 650 Vf (mm/min) 10,000 12,000 12,000 13,000 14,000 12,000 13,000 12,000 13,000 12,000 13,000 13,000 12,000 1.3 < 750 2.1 Alloyed steel < 600 n (rpm) 32,000 21,000 15,000 12,000 11,000 9,000 8,000 7,000 6,000 6,000 5,000 5,000 5,000 2.2 < 950 Vf (mm/min) 9,000 12,000 11,000 12,000 13,000 10,000 12,000 11,000 12,000 11,000 11,000 11,000 11,000 4.1 Stainless steels < 1500 n (rpm) 24,000 16,000 12,000 10,000 8,000 6,500 6,000 5,000 4,500 4,000 4,000 3,500 3,000 4.2 ferritic, martensitic < 1500 Vf (mm/min) 7,000 8,000 8,000 9,000 9,000 8,000 9,000 8,000 9,000 8,000 8,000 7,000 6,000 4.3 < 1500 8.1 Toolox 44 45-55 HRC n (rpm) 22,000 16,000 12,000 9,000 7,500 6,500 6,000 5,000 4,500 4,000 4,000 3,500 3,200 ≤rp2=ap 0.1 × rp ae=0.3 × d1 Vf (mm/min) 6,000 7,000 6,000 8,000 8,000 7,000 8,000 7,000 8,000 7,000 8,000 7,000 6,500 >rp2=ap 0.2 × rp ae=0.3 × d1 8.2 Hardened material 55-60 HRC n (rpm) 16,000 10,000 8,000 6,000 5,000 4,500 4,000 3,500 3,000 3,000 2,500 2,500 2,000 ≤rp2=ap 0.05 × rp ae=0.3 × d1 Vf (mm/min) 2,500 3,000 3,000 3,000 3,500 3,000 2,500 2,000 2,200 2,500 3,000 2,800 2,200 ≤rp2=ap 0.1 × rp ae=0.3 × d1 l7 ≤ 4 × d1 100 100 100 l7 ≤ 5 × d1 70 70 80 l7 ≤ 6 × d1 50 50 70 Material group ap = 0.1 × rp ae = 0.3 × d1 overhang length l7 Vc - % ap - % Vf - % Recommended cutting data for high performance mills Material group Unalloyed steels <850 N/mm² Alloy steels < 1100 N/mm² High alloy steels < 1400 N/mm² Stainless steels 35 - 45 HRC Titanium < 1200 N/mm² Cast irons < 250 HB 1.1 – 1.2 2.1 - 2.2 - 2.3 3.1 - 3.2 4.1 - 4.2 - 4.3 6.1 - 6.2 7.1 - 7.2 - 7.3 - 7.4 d1 Vc mm/ min fz/mm Vc mm/ min fz/mm Vc mm/ min fz/mm Vc mm/ min fz/mm Vc mm/ min fz/mm Vc mm/ min fz/mm 6.0 8.0 180 180 0.028 0.040 180 180 0.028 0.040 140 140 0.028 0.040 60 60 0.020 0.030 40 40 0.020 0.030 120 120 0.028 0.040 10.0 12.0 180 180 0.050 0.060 180 180 0.050 0.060 140 140 0.050 0.060 60 60 0.040 0.050 40 40 0.040 0.050 120 120 0.050 0.060 14.0 16.0 180 180 0.060 0.080 180 180 0.060 0.080 140 140 0.060 0.080 60 60 0.050 0.060 40 40 0.050 0.060 120 120 0.060 0.070 18.0 20.0 180 180 0.080 0.100 180 180 0.080 0.100 140 140 0.080 0.100 60 60 0.060 0.080 40 40 0.060 0.080 120 120 0.080 0.100 < 6 = ap 0.75 × D > 8 = ap 1.00 × D > 6 = ap 1.00 × D > 1.3 ×D Recommended cutting data for Karnasch 1×D solid carbide roughing end mills Vc = Cutting speed (m/min) Vf = Feed rate (mm/min) fz = Feed per tooth (mm) ae = Width of cut (mm) ap = Depth of cut (mm) n = rpm 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
