探讨了磨削金属镍时砂带的磨损机理,分析了不同种类砂带在不同磨损阶段的磨损形式。指出:在初期磨损阶段,砂带磨损形式主要是磨粒脱落与破裂;在稳定磨损阶段,砂带主要磨损形式是磨粒破碎与磨损。文中还提出了延长砂带使用寿命的几种方法。
The wear mechanism of abrasive belt when grinding metal nickel was discussed. The wear patterns of different kinds of abrasive belt at different wear stages were analyzed. It is pointed out that in the initial stage of wear, abrasive wear and tear is the main cause of abrasive particles falling off and cracking. In the steady wear stage, the abrasive wear and tear is the main form of abrasive wear. The paper also proposed several ways to extend the service life of the belt.
