In order to improve the performance of hot pressed sintered diamond saw blade heads,reduce the difficulty of laser welding of the blade heads,and meet the quality requirements of engineering practice for diamond saw blade heads,an orthogonal experiment was designed to study the influence of sintering technology on the density of the di-amond saw blade head matrix through range analysis.The orthogonal experiment results were verified by SEM mi-crostructure analysis,hardness,and bending strength testing.The study found that sintering temperature has the most significant effect on the density of diamond saw blade body,followed by sintering pressure,and the effect of insulation time is the smallest.Moreover,under the optimal process parameters of orthogonal experiment,the hardness and bending strength of the blade body reach their maximum values.
