| 45 | Method of Joining Two Components to Ensure Axial and Angular Alignment Therebetween | US13658891 | 2012-10-24 | US20130101362A1 | 2013-04-25 | Dwight E. Dyer; Ray Phillip Conley |
| A method for bonding together components, such as a tip and a shaft which include mutually facing carbide end surfaces. The tip includes circumferentially spaced flutes formed in its cylindrical outer periphery. The shaft has a cylindrical outer periphery and a plurality of coolant holes extending through the shaft. Bonding of the tip to the shaft is performed by inserting gauge wires into the coolant holes and associated flutes, and positioning brazing material between the first and second end surfaces. A water-soluble bond-blocking material is applied to the gauge wires for preventing brazing of the gauge wires to the brazing material. The brazing material is heated to braze the first and second end surfaces together while the flutes and their associated coolant holes are maintained in alignment by the gauge wires. Then, the gauge wires are removed, and residual bond-blocking material is dissolved in water. | ||||||

| A method for producing carbide and diamond cutting tool inserts adapted to compensate for braze-induced warp is provided. In this method, the anticipated warpage of the insert from brazing is considered prior to cutting the insert from a PCD and carbide disk and the cutting path for the insert is adjusted to compensate. The adjusted cutting path creates an insert shape that, after warping as a result of the brazing process, will conform substantially to the originally intended insert or cutting tool shape. Also, a method of providing relief on the bottom surface of a brazeable insert is provided. Further, tools produceable by these methods are disclosed, such as a diamond edged rotary cutting tool with a substantially sinusoidal rake face and cutting edge. | ||||||
