- Advanced materials, such as high abrasion resistant cast iron, have great applications for abrasive and erosive environments. Since the amount and the hardness of the microstructural carbides constituents in this material is extremely high, the abrasion-resistance cast iron is generally difficult to be machined with traditional cemented carbide tool. The hard and abrasive particles in this material can remarkably shorten the cutting tool life through abrasion of tool face and deterioration of cutting edge. In this article, Cubic Boron Nitride (CBN) cutting tool has been used to machine a novel-abrasion-resistance (N-AR) cast iron. The performances of CBN tool under different lubrication conditions were evaluated in view of tool wear, cutting force, and surface roughness (Rz). Further more, the wear rate of CBN tool under different machining condition and the mechanism of the CBN tool in machining of this type of work materials has also been investigated.

- Highly abrasion and erosive resistance materials are an important group of materials and has very wide applications in many industrial areas. The characteristic properties for this material include the castability and the superior wear resistance. The material, however, is in the group of hard-to-machine materials due to its abrasion to cutting tool and low thermal conductivity. In this article, the experimental results were reported on machinability of a N-AR cast iron with use of PCBN cutting tool, mainly focusing on the determination of machining conditions, possible tool life and tool wear. Cutting forces and chip morphology of the N-AR iron material were also examined during the investigation to clarify the reason of high tool wear rate in the machining.
