IS80 CVD Coated Si3N4 IW7 AL2O3+Sic Whiskers

• Multi-layered coating on IS8 matrix
• High fracture toughness due to SiC (silicon
• Roughing and interrupted (1) cutting on cast iron carbide) whisker reinforced ceramics
• Excellent thermal shock resistance, which enables using coolant and interrupted cut machining
• Excellent for roughing and semi-finishing operations at 8-10 times faster cutting speeds when compared with carbide grades
• Good oxidation resistance due to its alumina substrate Cutting Speed (m/min)

IS9 Si3N4 Turning Nickel Based Alloys

• Very tough Si3N4 ceramic grade with high cutting edge stability
• Machining on nickel based high temprature alloys, in roughing to finishing applications
• Honing is the standard edge preparation
