Abstract
A laser machining apparatus comprising jet liquid, a laser beam, and a laminar flow forming channel for supplying jet liquid to a nozzle. The channel includes a distribution channel formed by a cavity, an interconnecting channel disposed to communicate with said channel downstream in an axial direction of the nozzle and formed by an annular cavity around the axis of the nozzle to provide a narrower flow passage, and a liquid reservoir chamber. Said chamber has an outer peripheral edge communicating with the interconnecting channel over an entire circumference of the annular shape. An outer peripheral surface and an outer peripheral surface of the chamber form a continuous surface and an inner peripheral wall surface and an inner peripheral surface of the channel are both formed as an inclined inward surface that is downstream, the inner peripheral surface and the inner peripheral wall surface forming a planar continuous surface.
