摘要： 对钠钙玻璃进行磨削实验，研究了磨削参数对加工后钠钙玻璃表面粗糙度和形貌的影响.探讨了不同涂层微磨具磨削后已加工表面形貌和不同冷却条件下表面的粗糙度.实验结果表明:随磨削速度的增加，磨削深度和进给速度减小，已加工表面粗糙度减小，表面形貌更光滑、质量更好.在不同冷却条件下，湿磨已加工表面粗糙度值更低，表面质量更好.相同粒度的CBN微磨具和金刚石微磨具相比，金刚石涂层微磨具加工表面质量更好，更适宜对玻璃等硬脆材料进行磨削加工.

关键词: 涂层微磨具;磨削性能;表面形貌;表面粗糙度; 表面质量

Abstract: The grinding experiment of soda-lime glass was carried out to study the effects of grinding parameters on the surface roughness and morphology of the glass. The surface morphology was compared after grinded by different coated micro-grinding tools and surface roughness under different cooling conditions were also analyzed. The results show that when the grinding speed increases and the grinding depth and feed rate decrease， the surface roughness decreases and the surface morphology becomes smoother and better. Under different cooling conditions， the level of surface roughness after wet grinding is lower and the surface quality is better. In comparison with the CBN-coated micro-grinding with the same granularity， the diamond-coated micro-grinding can perform a better surface quality and more suitable for hard and brittle materials， such as glass.

Key words: coated micro-grinding tools; grinding performance; surface morphology; surface roughness; surface quality
