1 MEGCO MEGCO Ceramic P600M New MEGCO ceramic achieves significantly longer tool life, approaching that of CBN dvantages Superior economic efficiency in the machining of hardened materials Good wear resistance for high speed machining of gray cast iron

2 dvantages 1.With the use of MEGCO, it achieves a significantly longer tool life approaching that of CBN 2.chieves superior economic efficiency in the machining of hardened materials 3.Good wear resistance for high speed machining of gray cast iron MEGCO Special PVD coating Controls crater wear and achieves stable machining with superior oxidation resistance Hardness (Hv) icn in iin MEGCO High oxidation resistance( > =1000 C) Controlling oxidation wear Oxidation temperature ( C) Ceramic substrate characteristics P600M Conventional Black Ceramic P600M achieves miniaturization of the structure Compared to conventional black ceramic, the hardness, fracture toughness strength and oxidation resistance have been improved to achieve longer tool life Sudden fracturing is controlled through miniaturization of the ceramic structure Static property comparison of P600M and Conve. grade Hv (GPa) K IC (MPam 1/2 ) Strength (MPa) Oxidation resistance *1 (mg/cm 2 ) P600M Conve *Oxidation resistance: he increase in weight per unit area when atmospherically oxidized for one hour at 1200 C

B competitor CBN B competitor CBN P600M Cutting condition: Vc=100m/min, ap=0.2mm, f=0.1mm/rev, Wet Work material: SCM415H(Hardened) 58~62HRC Cutting ime (min) (Internal evaluation) he wear resistance of P600M is similar to that of competitor's CBN and B for low speed machining of hardened materials Chipping resistance comparison (for machining of hardened materials) P600M Cutting condition: Vc=150m/min, ap=0.2mm, f=0.15mm/rev, Dry Work material: SCM415H (Hardened) 58~62HRC Conve. B Number of hits (Internal evaluation) Chipping resistance is significantly improved compared to conventional black ceramic. Ceramic structure miniaturization plus MEGCO allow P600M to achieve significantly longer tool life for machining of hardened materials and gray cast iron. 2
