39. Performance of CF1 (KX213) in Ni based alloy machining is good at higher cutting speed (500m/min) for finishing application such as less than ap 1.5mm. Lower cutting speed is also available such as 200-300m/min. However, to show the difference against WG300 (Wisker),we recommend higher cutting speed. We recommend workpiece material hardness need to be under HRC 45. To choose suitable edge preparation is very important ConclusionsConclusions
