摘　　要：在多次对硬脆性材料玻璃进行超声振动研磨钻孔试验的基础上,分析了试验样品中出现的边崩和表面加工质量的缺陷原因,提出了避免边崩的措施。探求了磨料颗粒大小对加工形成的表面粗糙度的影响,并进行了分析。试验结果表明:随着磨料粒度的增大,即磨粒直径的减小,加工表面粗糙度降低,加工出来的孔精度与质量可满足建筑安装、装璜等工程技术的要求。Basing on the many tests of grinding and drilling with ultrasonic vibration on hard and brittle glasses, this paper analysis the reasons why limitation of surface processing and edge collapse appear among test samples, and then introduces the measures to prevent edge collapse. It also studies the effect of the abrasive particle size on the roughness of surface and then makes analysis. The test result shows that the bigger the abrasive grain size, that is the smaller the diameter of grinding material, and the lower roughness of surface processing. The precision of processed pinhole and the quality can meet the needs of engineering such as construction and decoration on buildings.
