Abstract
An abrasive tool and method for assembling same includes a first base having a front surface and a back surface and a second base having a front surface and a back surface. A first perforated sheet has a front surface and a back surface, the back surface of the first perforated sheet being bonded to the front surface of the first base. A second perforated sheet has a front surface and a back surface, the back surface of the second perforated sheet being bonded to the front surface of the second base. A first layer of abrasive grains is bonded to the front surface of the first perforated sheet, and a second layer of abrasive grains is bonded to the front surface of the second perforated sheet. The back surface of the first base is bonded to the back surface of the second base. The back surfaces of the bases may be bonded by sonic welding.
