Chilled cast iron is a typical hard and brittle material, often be used to make all kinds of roller. According to chilled cast iron machining characteristics, cutting tool material should has high red hardness, good impact resistance and wear resistance, high bending strength and large thermal conductivity coefficient. For determination of the suitable cutting parameters in machining chilled cast iron by PcBN cutting tools dry turning, the samples which are prepared to be used in the experiment, 200 mm in length and 120 mm in diameter, are machined in lathe. During experiments, cutting tool parameters and dry turning parameters, such as edge chamfer width and angle, feed rate, cutting speed and cut depth are investigated. The suitable edge chamfer width and angle, cutting speed and feed rate are determined according to cutting tool life and cutting tools flank wear. Finally, edge chamfer width of 0.2 mm, edge chamfer angle of -15 degree, cutting speed of 90 m/min, feed rate of 0.15 to 0.2 mm/rev and cut depth of 0.3 mm gave the satisfied results.
