Received November 25, 2015; Revised February 1, 2016; Accepted February 2, 2016 ABSTRACT The tool life in cutting high-nickel alloy is shorter than that in turning of carbon steel. In order to identify an effective tool material for the cutting of high-nickel alloy, the chip configurations, the tool wear and the surface roughness were experimentally investigated. The high-nickel alloy was turned with high-pressure coolant supplied. The results are as follows: (1) In turning with high-pressure coolant supplied, the effectiveness of chip breaking performance was improved. In this case, the chip length was shorter with the increase of the coolant pressure. (2) In the case of finish cutting high-nickel alloy, in the dry cutting large notch wear on the depth of the cut line was observed. In wet cutting with the cbn content of 60 % to 65 % under high cutting speed and high-pressure coolant supplied, it was possible to suppress the large notch wear. (3) In the high-pressure coolant cutting method of high-nickel alloy with a sintered cubic boron nitride compact tool, the cbn content of 60 % and the main element of the binder phase of Al 2 O 3 -Al was an effective tool material. (4) In the high-pressure coolant cutting method of high-nickel alloy with the cbn content of 60 % and the main element of the binder phase of Al 2 O 3 -Al, if the cutting coolant pressure is high and the cutting speed is low, large tool damage occurs to the notch boundary of the flank, and the tool life is short. In conclusion, the tool life of the cbn content of 60 % and the main element of the binder phase of Al 2 O 3 -Al can be improved by increasing coolant pressure in turning high-nickel alloy with a sintered cubic boron nitride compact tool under high cutting speed.
