Abstract

A nozzle for waterjet cutting apparatus comprises a nozzle body in which a hole is formed, the hole comprising a cylindrical bore formed concentrically with an adjacent outwardly tapered bore. The tapered bore can be conically or spherically tapered. The cylindrical bore defines an exit opening of the nozzle, and the tapered bore defines an inlet opening of greater diameter than the exit opening. Preferably the nozzle has a ratio of bore edge width W to hole diameter D (W/D) in the range of 4 to 15%. The nozzle body may comprise various hard materials including ruby, sapphire or diamond. In the case of diamond, the nozzle body can comprise single crystal diamond, polycrystalline diamond, or a sintered diamond material.
