  • Patent number: 6811579
    Abstract: A method for fabricating an abrasive tool having a work surface commences by applying an electrically non-conductive layer the work surface of the abrasive tool. A pattern is etched in the work surface preferably using a laser beam. Metal and abrasive particles are electroplated or electroless plated onto the work surface pattern. The non-conductive layer is removed from the work surface. Alternatively, an adhesive can be applied as a layer on the work surface. A negative pattern then is etched in the adhesive layer, i.e., the adhesive where no abrasive is desired is etched away. Abrasive particles then can contact the work surface to be adhered thereon to the remaining adhesive. Metal again can be electroplated or electrolessly plated onto the work surface. By multiple repetitions of both methods, different sizes and types of abrasive particles in different concentrations may be applied to different areas of the work surface.

  • Publication number: 20040155096
    Abstract: A superabrasive tool blank whose carbide side is affixed with a suitable braze alloy, for subsequent shaping into desired tool geometry and induction-brazed forming a cutting tool. The use of the pre-coated braze alloy in the tool blank forming cutting tools allows the direct brazing of the superabrasive blank onto a tool insert, thus minimizing operations and labor time involved for the shaping and handling of the braze substrate in the process of the prior art, i.e., the brazing of the assembly of the superabrasive tool blank, braze alloy, and tool insert. The pre-brazed blank can be conveniently used in automated brazing operations for forming cutting tools.
