Abstract

A product and a process for producing a matrix and a tool for use in abrasive or cutting applications including a base tool structure which may be armed with a plurality of triangular or conically shaped structures (24B) consisting of abrasive particles (32) bonded together in a braze metal (38). The structures (24B) may be prepared in a manner which provides a selectable rake angle. Rake angles including negative (46), neutral (46') and positive (46") may be produced. The process is accomplished by dif-fusing magnetizable abrasive particles on a release mechanism which has been placed on a reusable fixture (10) consisting of a plurality of balls (16) secured to a magnetized surface (14). The particles (32) stack to form structures (24) which are then encap-sulated in a braze paste (26). The axis of the structures (24) is aligned with the applied magnetic field, The cones are symmetrical if the magnetic field emanates perpendicularly from the magnetized surface. If the orientation of the magnetic field is distorted the conical structures will realign themselves therewith. In this manner conner conical structures (24) may be formed which offer selectable rake angles. The matrix (22) foamed by encapsulating the abrasive particles (32) may be removed from the release me-chanism (18) and secured to a base structure (30). Once this assembly has been brazed, the base structure may be used as an abrading or cutting tool.
