摘要
Abstract
According to theoretical analysis,different tool materials and geometry angles of cutting tools suitable for barium-tungsten cathode concave processing are chosen.Examined by metallographic microscope and scanning electron microscope,conclusions are drawn as follows:YG3X is suitable for finishing process of Ba-W cathode,while YG6 can be used for coarse and semi-finishing process.When choosing cutters with small front angle and large rear angle,the tool wear is small,and it is likely to obtain line clear surface.It is proved by diode test that the cathode with clear texture surface after turning has better emission uniformity.关键词
