The influence of rare earth and TiH2 on the performance of diamond segments in circular sawing of granites is presented. The consumed spindle power and the horizontal and vertical forces were in-process measured. The wear resistance of the segments was evaluated by the ratio of the amounts of granite being cut to the dimension decrease of segments in radial direction. A scanning electron microscope was used to examine the worn surfaces of diamond segments. Correlation between the sawing performance and the bulk TRS was discussed. Experimental results revealed that by adding 0.8% rare earth the wear resistance of diamond segments increased greatly and both the consumed spindle power and cutting force decreased. However, adding 2% TiH2 into the diamond segments of saw-blades produced an opposite effect on the sawing performance. SEM micrographs indicated that there are much less pull-outs of diamond particles and the diamond grits have higher protrusion on the worn surface of saw-blades segments with 0.8% rare earth.
