Abstract:
1. A method for fabricating an abrasive cutting tool, the method comprising: (a) providing a deposition disc having at least one deposition surface; (b) placing the disc in a bath having a fine grit abrasive dispersed therein; (c) depositing a first layer of the fine grit abrasive and electroplating material onto the deposition surface; (d) removing the disc from the bath; (e) activating a surface of the first layer; (f) placing the disc in a bath having a second abrasive of a second grit size larger than that of the fine grit abrasive dispersed therein; (g) depositing a second layer of the second abrasive and electroplating material onto the first layer; (h) removing the disc from the bath; (i) activating a surface of the second layer; (j) placing the disc in a bath having the fine grit abrasive dispersed therein; (k) depositing a third layer of the fine grit abrasive and electroplating material onto the second layer; and (l) removing the disc from the first layer, to produce a multi-layered cutting tool having abrasive particulate dispersed substantially completely therethrough, with a central layer of second grit size abrasive disposed between two layers of fine grit abrasive.
