Abstract

PURPOSE: To firmly hold a very hard diamond cutter by a flat titanium holder with large mechanical strength and high thermal resistance, by melting titanium powder contained in the cutter and sinter-bonding it to the holder.
CONSTITUTION: A mixture for forming a diamond cutting tool, composed of diamond powder and titanium alloy powder of three-dimensional network structure, is compressed to form a cutter on the one hand. Titanium alloy powder is presintered to form a flat titanium holder on the other. The cutter form is laid upon the holder form to get a built-up tool form. This built-up form is treated in a high pressure and high temperature atmosphere to melt the titanium alloy and sinter both forms. Thus the holder with large mechanical strength and high thermal resistance can firmly hold the very hard diamond cutter through a bonding layer.
