Estimating the term…
A bond material for a metal single layer abrasive tool, and especially for a tool with diamond abrasive, provides an excellent combination of mechanical properties including structural strength and impact resistance. The bond material is sufficiently compatible with both metal and diamond to effectively wet the abrasive grains and the core of the tool during brazing. The bond material can braze at a temperature range low enough that the core will not distort and diamond grains will not graphitize during brazing. The novel bond material composition contains a copper/tin bronze alloy; elemental titanium; zirconium; hard granular wear resistant particles; and elemental carbon. The wear resistant particles are preferably titanium carbide. Importantly, the bond produced from the material has superior wear resistance while remaining very adhesive to diamond.
An abrasive tool having abrasive grains disposed in a single layer of substantially one grain thickness and affixed to a cutting surface of a metal core by a bond composition suitable for brazing at a temperature of about 800.degree.-950.degree. C., and comprising:
A process of making an abrasive tool comprising the steps of:
