【Abstract】 In this study,tool-life tests with japan-made ceramics and carbide single- -point tools were performed on castiron in accordance with ISO 3685-1977. And tool-life plots and tool-life equations were obtained,thus the perfo- rmance of ceramics tool and its reasonable scope of application were discu- ssed,and the reliable data were provided for standard cutting.更多还原
