    摘要： A saw having a self-pumped hydrodynamic blade guide or bearing for retaining the saw blade in a centered position in the saw kerf (width of cut made by the saw). The hydrodynamic blade guide or bearing utilizes pockets or grooves incorporated into the sides of the blade. The saw kerf in the workpiece provides the guide or bearing stator surface. Both sides of the blade entrain cutting fluid as the blade enters the kerf in the workpiece, and the trapped fluid provides pressure between the blade and the workpiece as an inverse function of the gap between the blade surface and the workpiece surface. If the blade wanders from the center of the kerf, then one gap will increase and one gap will decrease and the consequent pressure difference between the two sides of the blade will cause the blade to re-center itself in the kerf. Saws using the hydrodynamic blade guide or bearing have particular application in slicing slabs from boules of single crystal materials, for example, as well as for cutting other difficult to saw materials such as ceramics, glass, and brittle composite materials.

    摘要： A slicing band consists of a base and an integral reduced cross section shank which is formed continuously throughout the length of the band. At the end of the shank is a scalloped cutting edge with inclined faces which intersect at the cutting edge of the scallops. The blade is constructed from an apparatus which utilizes two rotatable grinding wheels each with a flat annular grinding surface adapted to contact first one side of the blade and then the opposite side of the blade while the blade is yieldably retained against lateral movement and to effect material reduction to form the reduced cross section shank. The grinding wheel consists of cubic boron nitride, capable of performing material removal without burning or compromising the strength or other material requirements of the blade.
