A method for making an abrasive material comprising a plurality of hard particles providing the abrasive quality distributed in a retaining matrix for holding the particles in place, the method comprising the steps of placing a mask having openings therein against a carrier capable of supporting a plurality of the particles, providing an affixing capability to an outer side of the mask remote from the carrier to which hard particles will adhere, applying a plurality of hard particles to the outer side of the mask so that a portion of the particles pass through the openings of the mask and form a pattern of the particles on the carrier corresponding to the openings of the mask and another portion of the particles adhere to the mask, separating the mask containing the hard particles adhered to it from the carrier leaving the pattern of the particles on the carrier, at least partially surrounding the particles on the carrier with a retaining matrix material, and heating the retaining matrix material to cause the material to form a retaining matrix that holds the particles in the pattern.
A method for making an abrasive material comprising a plurality of hard abrasive particles distributed in a retaining matrix for holding said particles in place, said method comprising the steps of placing a mask having openings therein against a carrier for supporting a plurality of said particles, providing affixing means on an outer side of said mask remote from said carrier to which hard particles will adhere, applying a plurality of hard particles to said outer side of said mask so that a portion of the particles pass through the openings of the mask and form a pattern of said particles on said carrier corresponding to the openings of the mask and another portion of the particles adhere to said mask, separating the mask containing the hard particles adhered to it from the carrier leaving the pattern of said particles on the carrier, at least partially surrounding the particles on the carrier with a sinterable matrix material,. and heating said sinterable matrix material to cause said material to form a retaining matrix that holds said particles in said pattern and thereby form said abrasive material.
A method for making an abrasive material comprising a plurality of hard abrasive particles distributed in a retaining matrix for holding said particles in place, said method comprising the steps of placing a mask having openings therein against a carrier for supporting a plurality of said particles, applying a plurality of hard particles to an outer side of said mask remote from said carrier, whereby a portion of the particles pass through the openings of the mask and form a pattern of said particles on said carrier corresponding to the openings of the mask and another portion of the particles remain on the outer surface of said mask, adhering said particles on the outer surface of said mask to the mask, separating the mask containing the hard particles adhered to it from the carrier leaving the pattern of said particles on the carrier, at least partially surrounding the particles on the carrier with a sinterable matrix material, and heating said sinterable matrix material to cause said material to form a retaining matrix that holds said particles in said pattern and thereby form said abrasive material.
