| Abstract: | Stress state of thin kerf diamond bit manufactured by sintering method is analyzed based on molding theory of powder metallurgy and the shortcomings of flat contour of bit crown are pointed out. Semi circle like contour of bit crown for thin kerf diamond bit is proposed based on analyzing distribution of density and hardness of matrix of the bit and drilling process. |
