以青铜金刚石砂轮为试验对象，采用短脉冲光纤激光器，对金刚石砂轮的修锐进行了系统研究。理论分析了脉冲激光修锐青铜金刚石砂轮的机理, 试验研究了多脉冲激光烧蚀青铜轮的情况，借助超景深三维显微系统对烧蚀凹坑的微观形貌进行检测，总结了激光参数对烧蚀效果的影响规律。根据烧蚀试验结果选择最佳工艺参数，开展了激光修锐青铜金刚石砂轮的试验，并采用光学显微镜和磨削对比试验分别对修锐后的砂轮形貌进行了观测和评估。

Dressing experiment of bronze-bonded diamond grinding wheels using a nanosecond pulsed fiber laser is carried out. The systematic research starts with the mechanism of laser dressing, followed by the analysis of ablated crater impacted by multiple-pulse and the studies of relationship between pulsed laser parameters and ablation effect. The laser dressing experiments is carried out at the foundation of laser ablation and the surface topography after laser dressing on wheels are then observed and assessed by optical microscope and grinding experiment.
