[Ceramic] High Speed Machining for Cast Iron KS6050/CS7050 ● Improved fracture resistance by high aspect ratio constituents ■ Application Map ● Anti-chipping in scale processing and interrupted machining High ● High speed machining of cast iron by controlling grain boundary phase (good wear resistance) B ■ KS6050 Bridging Deflected crack High speed finishing Cutting speed L d Crack CS7050 General purpose Large aspect ratio ＝ L/d Conventional product A KS6050 KS6050 has a higher aspect Propagation of cracks interrupted machining Insert (Turning) ratio compared with the Large aspect ratio restrains propagation of cracks KS6050 conventional product A. Improved fracture resistance ■ CS7050 (Coated Si3N4) High wear resistant layer (TiC base) Low Finishing Medium Roughing Superior wear resistance attained Special Al 2 O3 layer Continuous Light Interruption Interruption with strong coating adherence Strong adhesion layer (TiN base) Applicable to high speed machining Si 3 N 4 Sub strate Heat-Resistant Alloys Machining SiAlON Ceramic KS6030/KS6040 ● Improved wear and fracture Superior balance in heat ■ Application Map resistance due to the mixture of resistant alloys machining ・Heat-Resistant Alloys Machining the hard and acicular particles achieves optimum balance between wear and fracture High CF1 Hard Particle resistance. (Improved wear → Cutting speed resistance) KS6030 Acicular Particle (Improved fracture resistance) ← Low KS6040 Low←Fracture resistance→High Continuous Light Interruption Interruption Heat-Resistant Alloys Machining Honeycomb structure Ceramic CF1 What is Honeycomb structure Ceramic? Comparison of Wear Resistance Honeycomb structure Ceramic is a composite 0.4 material consisting of a core (gray portion) and shell (white portion) 0.3 Nose Wear (mm) Prolonged tool life and acceleration of Notching Flank wear Notching Flank wear machining of heat resistant alloys such as Ni-base heat resistant alloys 0.2 Core Competitor C CF1 0.1 Workpiece Material: Ni-base heat-resistant alloys 0 Tool geometry: RNGN120400 Competitor C CF1 Competitor C CF1 Vc=150m/min, ap=1mm Shell Notching Flank wear f=0.15mm/rev Wet ■ Ceramic Inserts Identification System ● Identification System C N G A 12 04 04 S01525 “Turning Indexable Inserts Identification System” Refer to Page B2 Edge Prep.
