Abstract
An integral abrasive cutting tool comprising a multiplicity of equally spaced parallel coaxial abrasive cutting discs is formed by rotating a cylindrical mandrel coated with a matrix of abrasive powder in a metal in a fluid bath. A wire is aligned tangentially with the coating and voltage pulses are applied therebetween while the wire is fed in its lengthwise direction past the coating. The wire is translated axially to each of a plurality of disc spacing locations and, at each such location, translated radially to effect electro erosion of the coating forming a channel therein. An abrasive cutting disc is thereby provided between each pair of successive channels.
