  • Orifice for a waterjet cutter
    Patent number: 9808909
    Abstract: An orifice for a high-pressure waterjet cutter includes a first surface defining an inlet plane, a second surface defining an outlet plane, and an inner bore aligned along a flow axis and extending from the first surface to the second surface. The orifice also includes a first layer of polycrystalline diamond extending from the first surface to a plane between the inlet plane and the outlet plane, and a second, separate layer of polycrystalline diamond extending from the plane to the second surface. The first layer and the second layer are coupled to one another to define a single component. The second layer has material properties different than the first layer.
