ISOTURN INSERTS USER GUIDE IS80 CVD Coated Si3N4 IW7 AL2O3+Sic Whiskers High Speed Rough Turning on Grey Cast Iron Multi-layered coating on IS8 matrix Roughing and interrupted (1) cutting on cast iron Main Advantages High hardness (Hv 2,100) High fracture toughness due to SiC (silicon 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 IS9 Si3N4 Turning NickeI Based AIIoys 1 Very tough Si3N4 ceramic grade with high cutting edge stability 1 Machining on nickel based high temprature alloys, in roughing to finishing applications Honing is the standard edge preparation (1) Coolant is not recomended for interrupted cutting. 202 ISCAR
