High Speed Cutting for Cast Iron
Improved fracture resistance by high aspect ratio constituents Application Map
Anti-chipping in scale processing and interrupted cutting High
B High speed cutting of cast iron by controlling grain boundary phase (good wear resistance) High speed

product A Interruption
Aspect ratio = L/d Propagation of cracks
KS6050 has a higher aspect Large aspect ratio restrains propagation of cracks cutting
ratio compared with the
conventional product A. Superior fracture resistance KS6050
CS7050 (Coated Si3N4) High wear resistant layer (TiC base) Low Finishing Medium cutting Roughing
Superior wear resistance attained Special Al2O3 layer Continuous Light interruption Interruption
with strong coating adherence Strong adhesion layer (TiN base)
Applicable to high speed cutting Si3N4 carbide
