金刚石砂轮的精密修整是脆硬材料镜面磨削的关键技术之一，为了保证磨轮起到足够数量微小磨削刃的作用，以使脆硬材料镜面磨削得到较好的面形精度，超微粒金刚石砂轮精密修整技术是目前国内外研究的一个课题。这里介绍了目前国内外修整金刚石砂轮的各种技术方法，并提出采用碗形碳化硅修整器和在线电解修整法，可获得较理想的修整效果。
Precision grinding of diamond grinding wheel is one of the key technologies for mirror grinding of brittle and hard materials. In order to ensure that the grinding wheel plays a role of a sufficient number of tiny grinding edges so that the mirror surface grinding of the hard and brittle material can obtain better surface accuracy, the ultrafine particles Diamond grinding wheel precision dressing technology is currently a subject of research at home and abroad. Here are introduced at home and abroad trim diamond grinding wheel of various technical methods, and proposed the use of bowl-shaped silicon carbide trimmer and online electrolysis dressing method, you can get a more satisfactory dressing effect.
