摘要
对磨削性能下降的陶瓷CBN砂轮进行不同程度的修锐,用激光三角法的砂轮地貌测量系统对各状态下砂轮地貌进行测量。得到了砂轮地貌的三维形貌和磨粒出刃高度、磨粒刃密度的变化特点,以此评价修锐效果。结果表明,陶瓷CBN砂轮的修锐对砂轮磨粒的出刃性、等高性和均匀性有很大改善。
Different degrees of dressing were conducted for vitrified CBN grinding wheel with performance degradation.Topographies of the vitrified CBN grinding wheel were measured using the measuring system based on the Laser Triangulation in the dressing process.3D surface of the topographies as well as height and density of the grit protrusion were obtained,which were used to evaluate effect of the dressing.The results show the wheel grit protrusions after dressing have the features of baring,height-similar and well-distributed.
