PR1535 MEGACOAT NANO Fracture resistant with a tough substrate and high heat-resistant coating Stable machining of general steel, mold steel, and difficult-to-cut materials 1 Toughening by a new cobalt mixing ratio *In-house evaluation High toughness carbide base material 23% Fracture toughness* 2 Stability improvement The coarse grain structure and uniform particle size correspond to improved heat resistance, with conductivity values decreased by 11%. The uniform structure also reduces crack propagation. Cracking comparison by diamond indenter (In-house evaluation) Shock resistance PR1535 base material Conventional material Short cracks Long cracks 3 Stabilized turning operation and long tool life by special nano coating layer MEGACOAT NANO Prevents wear and fracture with high hardness (35GPa) and superior oxidation resistance (oxidation temperature 1,150° C) Hardness (GPa) Hardness (GPa) Coating properties (Abrasion resistance) 40 35 30 25 20 15 10 400 TiCN TiN MEGACOAT NANO TiAIN 600 Low 800 1,000 1,200 Oxidation temperature (°C) Oxidation resistance 1,400 High Achieve long tool life with the combination of a tough substrate and a special nano coating layer Coating properties (Deposition resistance) 40 35 30 25 20 15 10 0.3 TiCN 0.4 High MEGACOAT NANO TiN 0.5 0.6 Wear coe cient (μ) Deposition resistance TiAIN 0.7 0.8 Low Stable machining with excellent wear resistance ap (mm) ap (mm) ap (mm) Cutting condition (External) 5 Stainless steel 4 3 PG MU 2 1 MQ MS 0.1 0.2 0.3 0.4 0.5 f (mm/rev) 4 Heat resistant alloy PG 3 2 MQ 1 MU MS 0.1 0.2 0.3 0.4 0.5 f (mm/rev) 4 Titanium alloy PG 3 MU 2 MQ MS 1 0.1 0.2 0.3 0.4 0.5 f (mm/rev) Workpiece material Vc (m/min) Min. – Recommendation – Max.
