Abstract
A laser machining nozzle includes: a nozzle body coupled to a machining head; and a flow path formed through the nozzle body in a longitudinal axis of the nozzle body to allow a machining-assist gas to be injected toward a workpiece therethrough while a laser beam is emitted toward the workpiece, wherein the flow path comprises a first flow path formed in a flow direction of the machining-assist gas and generating a supersonic flow of the machining-assist gas; a second flow path connected to the first flow path in the flow direction of the machining-assist gas and expanding a volume of the machining-assist gas having passed through the first flow path; and a flow path boundary defining a boundary between the first flow path and the second flow path.
