MFH Harrier 4 POINT. Applicable for Variety of Workpieces New Development from Steel to Heat-resistant Alloys High Toughness Substrate New grade for difficult-to-cut material which controls Smooth TiN layer sudden fracture and realizes stable machining Smooth & less adhesion Improved stability Tough α-Al2O3 layer For Martensitic stainless steel and Ni-base heat-resistant alloys Prevents oxidation and wear of coating layer due to high heat-resistance of aluminum oxide High heat resistance and wear resistance with CVD coating Special Interlayer Prevents peeling of coating layer Improved stability due to thin layer coating technology Ultra Fine TiCN layer CA6535 High aspect ratio and micro columnar TiCN coating layer improves abrasive wear resistance For Ni-base heat-resistant alloys, titanium alloys and precipitation hardened MEGACOAT base multi-layer structure stainless steel Stable and longer tool life by special nano coating layer MEGACOAT NANO PR1535 ● Wear Resistance Comparison SKD11 Ni-base heat-resistant alloys 0.30 0.30 Competitor E Competitor D Competitor F CA6535（GM） Wear [mm] Competitor C 0.20 Wear [mm] 0.20 PR1525（GM） 0.10 0.10 M 0.00 0.00 0 10 20 30 40 50 60 70 80 0 5 10 15 20 Cutting Time [min] Cutting Time [min] Vc=150m/min, fz=1.5mm/t, ap×ae=1.0×16mm, Dry Vc=30m/min, fz=0.8mm/t, ap×ae=1.0×40mm, Wet ■ Case Studies Milling SFVAF22B (Forged alloy steel) SUS304F Machining Chattering reduced Machined portion efficiency 3 times Machining efficiency 1.6 times ・Turbine parts　・Vc=160m/min　・fz=1.17mm/t ・Clutch　・Vc=120m/min　・fz=1.2mm/t ・ap×ae=1.5×max.160mm　・Dry ・ap×ae=1.0×20mm　・Dry ・MFH160R-14-8T（8 inserts）・SOMT140520ER-GM（PR1525） ・MFH32-S32-10-2T (2 inserts)　・SOMT100420ER-GM（PR1535） PR1525 Chip Evacuation Rate = 720cc/min PR1535 Chip Evacuation Rate = 58cc/min Competitor G Chip Evacuation Rate = 240cc/min Competitor H Chip Evacuation Rate = 36cc/min ・Small machining noise even at 3 times higher feed rate ・Competitor H caused chattering but MFH realized stable machining ・Good edge condition without chipping and stable machining ・Good edge condition and long tool life (Evaluation by the user) (Evaluation by the user) M115
