The diamond wire saw beads (dwsbs) find huge applications in the stone cutting industries. the properties of marblesstones vary from mine to mine. the performance of diamond wire saw beads, in terms of cutting productivity and the service life depend largely on its physical and mechanical properties. besides hardness, the wear resistance of bead is a major parameter that affects wire-sawing operation. as part of the research work, a simulated wear test rig was fabricated in order to provide rotational motion (30 rpm) to wire saw bead (wsb) and tangential motion (1500 rpm) to granite disc where in bead was allowed to slide on the counter face disc of granite material and thus wear performance of wire saw bead was investigated at applied load of 0.5kg. the wsbs were fabricated by varying chemical composition of electrolytic iron powder, tin and bronze (75% cu-25% sn) and other essential elements like nickel, copper, tungsten, aluminum and tin. these powder mixes were blended in a mixer with a ball to powder ratio of 10:1 (by wt.) for 2 h. then this blended powder was mixed manually with synthetic diamonds (5%) and 2% kenolube. the cobalt free wsbs were fabricated by using hot press sintering furnace at 820�c, 880�c, 900�c and 920�c hot-press sintering temperature. the effect of sintering temperature and various alloying elements on its properties like sintered density, hardness and wear rates were analyzed and compared with commercially available wsb containing 22% cobalt. it clearly shows that sinterability of wire saw bead enhances due to presence of liquefying agent such as sn and bronze. the abrasive wear gives rise to the severe continuous grooving marks on granite disc, which might come due to exposure of diamonds. this is followed by discussion on wear mechanism provided in the given system. overall, the cobalt free wsbs can be successfully fabricated at ordinary low cost (63%) and less energy (12%).
