【Abstract】 The performance characteristics of CVD diamond thick film cutters are analyzed. The experiments on the precision cutting and hard to cut composite materials cutting by using CVD diamond thick film turning tools are carried out. The experiment results show that the roughness of R a0 05μm on the machined aluminum alloy surface can be obtained, and the wear resisting property and lifespan of CVD diamond thick film cutters are remarkable better than that of the carbide, PCD and PCBN cutters during turning hard to cut composite materials.更多还原
