作者:admin      发布日期:2019-07-03 Tag标签: 切削液

信息摘要:

刀具失效编辑刀具磨损是切削加工过程中不可避免的现象,但刀具磨损过快或发生非正常磨损(也称破损),必然会影响加工质量,增加刀具消耗,使生产效率降低,加工成本提高。

黏结磨损是切削时切屑和工件材料沿刀具前、后刀面移动,破坏了刀具表面的氧化层和其它吸附膜,特别是刚从工件材料内部切削出的新鲜表面间形成强烈黏结造成的磨损。切削速度与黏结磨损之间存在着非常复杂的关系,一般黏结磨损主要发生在中等切削速度范围内,刀具材料与工件材料之间的亲和力、刀具材料和工件材料之间的硬度比以及刀具材料组分、晶粒粗细、刀具表面状态和切削液类型等都影响刀具黏结磨损速度; [1]
