Notes:
An investigation was undertaken to elucidate the mechanisms for the fracture failure ofbrazed diamonds in wire sawing. Diamonds were brazed by high-frequency induction in vacuum.The changes of compressive strength and the appearances of the diamonds at different brazingtemperatures were obtained. The morphologies of the diamonds after sawing were also observed.Together with the stress analysis of a brazed grit, it is found that the fracture failure of brazed grit isthe result of the brittle fracture happening on the root section of the grit, the interface between thegrit and the brazing alloy. The degradation of mechanical properties of grits in brazing is a keyfactor to the reduction of their resistance to fracture. Lower machining forces as well as gritexposure are in favor of preventing grits from fracture
