Hybrid Cermet Uncoated Cermet MEGACOAT NANO Cermet TN610/TN620 PV710 / PV720 Three types of special reinforcement technology (Hybrid Technology) realized the superior surface finish and stability Excellent surface finish Combininq the conventional cermet bonded phase (nickel, cobalt) Surface finish comparison cutting conditions: vc=iso o m/min (Constant rate), ap = 0.5 mm (Internal evaluation) f = 0.1 mm/rev, Wet, CNMG120404 type Workpiece Material: S10C and the special high melting point metallic bonded phase Minimizing softening bonded phase at cutting and high deposition resistance and excellent finishing surface quality Special reinforcement technology 1 High melting point “ hybrid bonded phase” High speed Low speed Surface Finish Surface Roughness ( 4 15) i (Vc = 15 55 m/min) PV720 Competitor A i Excellent fracture resistance Improved strength by uniform micro grain hard phase and superior compressive stress by high melting point bonded phase. Fracture resistance improved Special reinforcement technology 2 Micro grain “hybrid hard phase” TN620 structure mmmmrnmmHm 'Hi . < Inner structure Compressive residual stress in hard phase (Internal evaluation) High Low 20%h TN620 Conventional micro grain cermet R Bad .Mmj 1C Excellent wear resistance Excellent fracture resistance with the surface-hardened layer using the gradient composition technology Good balance of stable wear resistance and fracture resistance TN620's inner structure has high toughness and chipping resistance as well as thermal shock resistance. Surface area has higher hardness and wear resistance compared to the conventional micro grain cermet S.
