ABSTRACT:
A bond for a single layer metal bond abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. In one aspect, the novel bond consists essentially of a ternary bond composition of copper, tin and titanium, in which the copper and tin are pre-alloyed and the pre-alloy and titanium component are incorporated in the bond composition as fine particle size powders. In another aspect, the bond is a quaternary bond composition consisting essentially of copper, tin, titanium and silver. The powder components can be used dry or mixed with a fugitive liquid binder as a paste. The novel bond can be brazed at lower temperature than copper/tin/titanium bonds prepared otherwise. The bond composition forms a good melt at braze temperature that flows smoothly, evenly over a tool preform and provides consistent quality bonding of abrasive from tool to tool.
