本文致力于研究一种基于柔性涂层砂带上固定颗粒的变化特征与磨削性能之间的普遍关系的鉴定方法，以实现一种用于精密砂带磨削的涂层磨料的评估方法。 A set of parameters was defined which describe the aluminium oxide resin-bonded belt characteristics including active grits density, cutting edge dullness, chip storage space and mean effective indentation.对磨削不同工件材料时，不同粒度的涂层砂带特性对表面光洁度性能的影响进行了参数研究。讨论了与带-工作界面处的过程的主要机制相关的实验结果，该过程可以分为切割和犁耕部分。这还能够描述在研磨两种工程材料时使用涂附磨料操作的砂粒磨损机制。
This paper addresses a study to achieve a method of assessment of coated abrasives for precision belt grinding based on the identification of the prevailing relationships between the changing features of fixed grains on flexible coated belts and grinding performance. A set of parameters was defined which describe the aluminium oxide resin-bonded belt characteristics including active grits density, cutting edge dullness, chip storage space and mean effective indentation. A parametric study was made of the effects of coated belt characteristics on surface finish performance with different grain sizes for grinding different workpiece materials. Experimental results are discussed in relation to the prevailing mechanisms of the process at the belt-work interface which can be separated into cutting and ploughing components. This enables also to describe the grit wear mechanisms operating with coated abrasives when grinding two engineering materials.
