Abstract (en)

[origin: EP1252975A2] To provide an electro-deposited thin-blade grindstone containing a plate-shaped base metal (12), depressed portions (14) that are open from near the edge portion (12a) of the base metal to the edge portion (12a) and are formed alternately on both side surfaces of the base metal, and a number of abrasive grains (16) fixedly deposited on the depressed portions (14) and protruded from the side surfaces and end portion of the base metal (12). The depressed portion (14) is formed in a depth of 1/2 or more of the thickness of the base metal (12). The abrasive grain is a hard abrasive grain (16) made of diamond, CBN or the like. The diameter of the abrasive grain (16) is nearly equal to the thickness of the base metal (12). <IMAGE>
