OBSERVATION OF WEAR FORMS OF DIAMOND TOOL

  • 摘要: 本文对金刚石工具的磨损进行了研究。扫描电镜观测表明,金刚石工具磨损包括轻微磨损和严重磨损两大类。轻微磨损包括金刚石的犁沟磨损、剥层磨损和点蚀磨损等形式;严重磨损包括金刚石碎裂磨损、胎体与金刚石界面挤出与离隙和整体脱粒等形式。分析了各种磨损形式产生的原因和机理,指出金刚石工具的出刃高度h随轻微磨损而减小,却随严重磨损而增大。金刚石的严重磨损虽然可以提高磨削效率,但却影响工具的使用寿命。
    Abstract: The wear of dismond tools has been studied. The SEM observation has shown two kinds of wear including mild wear and severe wear. The mild wear involves grooved wear,delamination wear and spot etching, while the severe wear covers crack wear, squeezins and seperating interface matrix and diamond,breaking off of whole dismond,etc. The cause and mechanism of the production of various forms of wear have been analysed. It has been bound that the height above the edge of diamond tools decreases with mild wear but increases with severe wear(Though the severe wear of diamond can present a higher grinding efficiency,it diminishes tools' lifetime.
