Cell fiber technology Core High Hardness …. . Wear resistance Shell High Toughness …. . Chipping Resistance Crack propagation resistance 200μm Surface Cutting performance can be controlled by changing the combination. Indentation Test (Vickers Hardness)
Conclusions Performance of CF 1 (KX 213) in Ni based alloy machining is good at higher cutting speed (500 m/min) for finishing application such as less than ap 1. 5 mm. Lower cutting speed is also available such as 200 -300 m/min. However, to show the difference against WG 300 (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
