Abstract
Superabrasive tools and methods for the making thereof are disclosed and described. In one aspect, superabrasive particles are chemically bonded to a matrix support material according to a predetermined pattern by a braze alloy. The brazing alloy may be provided as a powder, thin sheet, or sheet of amorphous alloy. A template having a plurality of apertures arranged in a predetermined pattern may be used to place the superabrasive particles on a given substrate or matrix support material.
Claims20
A method for making a superabrasive tool, comprising:
- arranging a plurality of superabrasive particles in a metal matrix at specific positions such that the plurality of sup erabrasive particles are held in the metal matrix according to a predetermined pattern, wherein tips of each of the plurality of the superabrasive particles protrude from the metal matrix to a uniform height, and wherein the plurality of superabrasive particles is positioned in the predetermined pattern at a first location and the predetermined pattern of the plurality of superabrasive particles is transferred to a second location for being held in the metal matrix.
A method for making a superabrasive tool, comprising:
- placing a template having a plurality of apertures corresponding to a predetermined pattern upon a transfer plate at a first location;
- filling the apertures with superabrasive particles;
- removing the template from the transfer plate;
- transferring the superabrasive particles to a second location using the transfer plate such that the superabrasive particles are arranged in the predetermined pattern, wherein tips of each of the plurality of the superabrasive particles protrude from the metal matrix to a uniform height;
- and
- forming a metal matrix to hold the plurality of superabrasive particles therein.
