对电镀金刚石砂轮轴的激光辅助整形进行了实验研究。在LBT中，Q开关模式的脉冲YAG激光器通过CNC运动在主轴工作表面的切向方向上照射，以使金刚石颗粒在所需轮廓上对齐。实验通过将空气涡轮式坐标磨床固定到YAG激光照射设备的数控工作台上进行。通过对钻轴上金刚石颗粒的扫描电镜观察，阐明了金刚石颗粒的热损伤尖端通过石墨化和氧化去除。以激光接近度为参数，跟踪了激光束位置对切割点密度和晶粒凸起的影响。在距套筒轴最外表面约70μm深的激光束与套筒轴干涉的位置处发现出现整形效应的位置。在适当的条件下，电镀金刚石套筒经激光磨削后，磨削力略有提高，但加工表面粗糙度优于未经激光处理的套筒。
As a method for profiling an electroplated diamond grinding quill in the noncontact manner, the laser beam-aided truing (LBT) is experimentally investigated. In the LBT, a pulsed YAG laser in the Q-switched mode is irradiated in the tangential direction of the quill working surface by means of CNC movements in order to allow the diamond grains to be aligned on a desired profile. The experiments were conducted by fastening a jig grinder of air-turbine type onto a NC table of YAG laser irradiation equipment. From SEM observation of diamond grains on the quill, it is clarified that the thermal impaired tips of diamond grains are removed by graphitization followed by oxidation. The changes of cutting point density and grain protrusion have been traced with the laser proximity as a parameter, and the laser beam position. at which the truing effect appears is found at the position where the laser beam interferes with the quill by about 70μm deep from the quill outermost surface. The electroplated diamond quill applied LBT under an appropriate condition brings about a little higher grinding force, however, the finished surface roughness is better than that of the quill without laser treatment.
