Abstract
The wear characteristics of sintered diamond composite segmented sawblades during circular sawing of granite were investigated. Scanning electron microscopy, optical microscopy and energy-dispersive X-ray analysis were used to identify wear mechanisms. The forces acting on the blade for various sawblades were also measured. The results obtained show that fracture of diamond particles can be attributed to impact forces and low cyclic surface fatigue, and wear of the matrix bond is due to flush erosion, cavitation erosion and abrasion. Blades containing diamonds with a greater degree of etching pits result in a relatively higher proportion of macro-fractured or polished (flattened) diamond particles, a larger vertical sawing force and sawing force ratio, and lower grinding ratio than those containing diamonds covered with less etching pits. © 1992.
