介绍了金刚石定位排列刀头中，不同的金刚石分布形式对其切割性能的影响，以及一种定位排列金刚石浓度的计算方法。使用不同金刚石分布方案的锯片切割钢筋混凝土，经实验验证：在金刚石浓度均为20%、胎体及金刚石品级都相同的情况下，四层金刚石组成的四明治结构定位排列锯片较常规锯片速度提高13.8%，刀头磨耗提升了13.3%；五层金刚石组成的错位定位排列锯片的切速较常规锯片的快34.8%，刀头磨耗降低了17.3%。体现了金刚石分布形式对切割对象的影响，合理的刀头结构不仅能提高锯片的效率也能提高切割寿命，但不合理的刀头结构反而会降低锯片的切割寿命。

Effect of diamond pattern on cutting performance of saw blades were investigated as well as the formula to calculate the concentration of arrayed diamond Three kinds of saw blades were used in the test to cut reinforced concrete Results indicated that with diamond concerntration of 20% and the same matrix and diamond grade the cutting speed of four-layer structured diamond saw blade increased by 13 8% but its tool wear increased by 13 3% the cutting speed of five-layer structured blade increased by 34 8% and the tool wear decreased by 17 3% This showed that the rational structure of diamond saw blade could improve the efficiency and life but the irrational structure would shorten the life.
