摘要： 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.

摘要： A bond for a metal single layer 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. The composition of the novel bond consists essentially of copper, tin and titanium. It can be brazed at temperatures below diamond graphitization and is chemically compatible with diamond. Hence, the bond is particularly useful for the manufacture of large diameter, superabrasive metal single layer abrasive wheels employed in the construction industry. The bond can be applied to the cutting surface of the abrasive tool as a uniform mixture of bronze alloy, titanium compound and copper powders. The powders may be mixed with a liquid vehicle and applied as a paste. The method of brazing the bond incorporates heating the bond composition to a temperature at most about 880° C. to melt the bronze alloy and titanium compound components, and raising the temperature to at least about 900° C. to dissolve the copper. The bond can also include an about 10-200 &mgr;m thick barrier layer of copper coating the cutting surface between the core and the bond composition.

摘要： An abrasive grit for a metal bonded Single Layer abrasive tool includes abrasive grains coated with a first active component. The active component is mechanically-bound to the surface of the superabrasive grains. Preferably the abrasive is a superabrasive, especially diamond, and the first active component is titanium, either in the form of elemental Ti or TiH.sub.2. The novel grit is made by mixing the first active powder component in a liquid binder to form an adhesive paste; mixing the paste with the abrasive grains to wet the grains, and drying the mixture to adhere active component to the grains. The coated abrasive can be brazed onto a core to form a Single Layer tool, especially with a brazing composition that includes a bronze alloy and small concentrations of a second active component. During brazing the novel abrasive grains provide excellent surface contact with the brazing composition and the braze strongly bind the grains to the tool core. The brazed composition is easy to chemically or electrochemically strip from the cores of worn abrasive tools to permit reconstruction of the tools.

摘要： A straight, thin, monolithic abrasive wheel formed of hard and rigid abrasive grains and a sintered bond including a metal component and an active metal component exhibits superior stiffness. The metal component can be selected from among many sinterable metal compositions. The active metal is a metal capable of reacting to form a bond with the abrasive grains at sintering conditions and is present in an amount effective to integrate the grains and sintered bond into a grain-reinforced composite. A diamond abrasive, copper/tin/titanium sintered bond abrasive wheel is preferred. Such a wheel is useful for abrading operations in the electronics industry, such as cutting silicon wafers and alumina-titanium carbide pucks. The stiffness of the novel abrasive wheels is higher than conventional straight monolithic wheels and therefore improved cutting precision and less chipping can be attained without increase of wheel thickness and concomitant increased kerf loss.
