WebApr 22, 2024 · The normal processing of sintered NdFeB magnets, used in many applied fields, involves diamond wire sawing. Due to the fact of its relatively lower hardness and high brittleness, the surface roughness and periodic waviness of the sawed surface have become a serious problem, but the surface formation mechanism is still unknown. In this … WebAbstract Improving the effective utilization of diamond wire saw silicon powder (DWSSP) waste is beneficial to increasing the production profit of the photovoltaic (PV) industry. It is also important to reduce the emissions of DWSSP to control environmental pollution.
