ABSTRACT:
An abrasive member comprises a non-magnetic substrate and a plurality of abrasive layers, which are overlaid upon the non-magnetic substrate, each of the abrasive layers mainly containing a binder and hard abrasive grains, which have a Mohs hardness of at least 6 and are dispersed in the binder. The plurality of the abrasive layers include a top abrasive layer and a lower abrasive layer, which is formed between the non-magnetic substrate and the top abrasive layer. The thickness of the top abrasive layer is at most A/2, where A represents the thickness of the lower abrasive layer. The mean grain diameter of the abrasive grains contained in the top abrasive layer is at most B/2, where B represents the mean grain diameter of the abrasive grains contained in the lower abrasive layer.
