高功率激光器作为氧化铝砂轮的非接触式修整工具正在探索中。氧化铝砂轮表面在激光修整时发生熔化和/或汽化，在表面形成改性层。发生晶粒尺寸的细化。在表面上形成的单个颗粒具有明确的小面结构。在单个晶粒和颗粒上产生微切削刃，其可以作为高效研磨的切削刃。X射线衍射和极图分析的结果表明，这些刻面结构的形成是由于修整后的晶粒的择优取向。
High-power lasers are being explored as a non-contact-type dressing tool for alumina grinding wheels. The alumina grinding wheel surface underwent melting and/or vaporization on the surface when laser-dressed, forming a modified layer on the surface. Refinement of the grain size took place. The individual particles that formed on the surface had well-defined faceted structures. Microcutting edges were generated on the individual grains and particles, which can act as cutting edges for efficient grinding. The results of x-ray diffraction and pole figure analysis suggested that the formation of these faceted structures was due to the preferential orientation of the grains after dressing.
