Sharpness of saw blades will be improved with coarsening of grit size under the condition of constant diamond concentration. By using chemical analysis method composition of the metal bond matrix of various diamond saw blades are analyzed. It is suggest to controlling the sharpness and duration of the saw blades by alternating the metal bond matrix formula as well as the grit size and strength of the diamond. Otherwise, the paper introduces the productive process of circular diamond saw blades. The role is played on the various issues and the reasonable manufacturing process is confirmed. Then it is suggested to adding sparse soil element, Self-propagating High –temperature Synthesis, the sintering of partial pre-alloyed saw segment mental powder for better bond performance.
