在钢坯修磨中,砂轮表面状态是磨削过程的一个重要输入参数,对金属切除,砂轮磨耗、功率消耗等均有直接影响。因此迫切需要建立反映砂轮磨除能力的客观指标,以方便砂轮的评价选择并为修磨理论研究建立一个新参数。本文由单个磨粒磨除能力入手,导出一 In the billet grinding, the surface condition of the grinding wheel is an important input parameter in the grinding process, which has a direct impact on metal removal, wheel wear and power consumption. Therefore, there is an urgent need to establish an objective index reflecting the abradability of grinding wheels to facilitate the selection of grinding wheels and to establish a new parameter for sharpening theoretical research.
