Cutting performance can be controlled by changing the combination.
Performance of CF1 (KX213) in Ni based alloymachining 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),werecommend higher cutting speed.
We recommend workpiece material hardness need to beunder HRC 45.
To choose suitable edge preparation is very important
