Abstract: Wear mechanism of diamond segments while sawing granites is analyzed. Failure features of diamonds with different quality and their demands on bonds are discussed. It is pointed out that using diamonds with mixed quality in the same segment is the main reason for abnormal loss of diamonds. On the basis of analyzing the characteristics of load distribution on the segments, it is recommended that diamonds with different quality and corresponding bonds should be used according to the load distribution on the segments. Experimental results show that by this measure sawing efficiency has been increased by 60 % and abnormal loss of diamonds have been decreased obviously on the premise of a constant cost and wear performance of the segments.
