Abstract
The present invention provides a superabrasive tools and methods for making the same. In one aspect, superabrasive particles are chemically bonded to a matrix support material according to a predetermined pattern by a braze alloy that contains Cr, Mn, Si, or Al or mixtures thereof.
Claims45
A method of making a superabrasive impregnated tool comprising the steps of:
- a) providing a matrix support material;
- b) locating a plurality of superabrasive particles at individually specified positions on a top surface of the matrix support material according to a predetermined pattern;
- and
- c) bonding the superabrasive particles to the matrix support material.
1 more element
A method of making a superabrasive impregnated tool comprising the steps of:
- a) mixing a metallic matrix support material powder having irregularly shaped particles with an average particle size of greater than about 400 mesh, with a brazing alloy powder, and an organic binder;
- b) placing a template having a plurality of apertures in a predetermined pattern upon a top surface of the mixture of matrix support material, distributing a plurality of superabrasive particles on a top surface of the matrix support material in a predetermined pattern said apertures being configured to hold one superabrasive particle each;
- c) removing the template;
- and
- d) binding the superabrasive particles to the matrix support material with a brazing alloy that contains between 2 and 50 percent of an element selected from the group consisting of chromium, manganese, silicon, titanium, and aluminum.
2 more elements
An abrasive tool consisting essentially of:
- a) a tool substrate;
- b) a plurality of superabrasive particles arranged at individually specified positions according to a predetermined pattern upon the tool substrate;
- and
- c) a brazing alloy which bonds the superabrasive particles to the substrate, said brazing alloy having at least two elements of at least 2 weight percent each selected from the group consisting of:
- chromium, manganese, silicon, aluminum, titanium, nickel, iron, cobalt, copper, and mixtures thereof.
