Abstract

In this paper the effectiveness of the binder-less PcBN tool with a sharp edge in the high-speed machining of soft magnetic materials. By using the binder-less PcBN tool with high-temperature hardness and high bending strength, we studied the effect of rake angle and cutting speed on the surface machined under a high-speed cutting condition. We then found that the surface roughness was reduced at a rake angle of -5 degrees by the increase of the cutting speed. On the other hand, the flank face wearing rate at a cutting speed of 20m/s decreased to 1/2.5 of the rate at a low cutting speed. The tool flank face wearing rate in the high-speed machining of pure iron, a major component of the work-piece material, was extremely higher than the rate in the machining of soft magnetic materials. It was found that the resin component of the work-piece materials remaining on the flank face in a graphitized form prevented the reaction between the binder-less PcBN tool and the iron, the main component of the work-piece materials.
