<p>A method of making a tool element comprising a plurality of abrasive grains dispersed in a matrix material, each abrasive grain having an aspect ratio substantially greater than 1, in which the abrasive grains are non-randomly oriented with respect to one another; the method including: combining the abrasive grains with binder material and precursor material from which the matrix material can be formed, to provide a paste body in which the abrasive grains are substantially randomly oriented; extending the paste body along two mutually orthogonal dimensions to provide a precursor structure in which the abrasive grains are substantially non- randomly oriented with respect to each other; at least partly removing or transforming binder material and treating the precursor structure to transform the precursor material into matrix material and providing the tool element.</p> |
