ABSTRACT:
Grinding stones, especially resinous and metallic grinding stones which have a controlled distribution of abrasive grains are made by a novel method, in which electrically conductive layers of such pattern which controls sites to be bonded with the grains are formed on the selected surface of a binder sheet, the sheet is immersed in an electrolytic bath containing metallic ions and the grains, the grains are fixedly mounted on the aforementioned sites by metals deposited on the surface of binder sheet with electric paths between the conductive layers and an opposite electrode in the bath, and a plurality of said sheets are placed in layers and warm or hot pressure-molded. When the binder sheet is made from electrically conductive materials, the pattern of the conductive layers is made by masking.
