Abstract:
To provide a nozzle for laser processing head capable of reliably drilling a small hole when drilling of the workpiece is performed by using a laser machine. A nozzle includes: a nozzle tip body that irradiates a workpiece with a laser beam; a charge port formed in the nozzle tip body; an exhaust port formed in the nozzle tip body so as to oppose to the charge port; and an elastic member that is provided in a tip end of the nozzle tip body and contacts with the workpiece while elastically extending and contracting in the axial center direction of the nozzle tip body. The nozzle supplies gas to the inside of the nozzle tip body along a gas flow path extending from the charge port to the exhaust port in a form of crossing across the laser beam in the nozzle tip body, to generate a negative pressure in the vicinity of an opening part of a tip end of the nozzle tip body. The elastic member contacts with the workpiece and improves the degree of enclosure of the nozzle tip body by the workpiece. Thereby, higher negative pressure than the negative pressure is generated.

Claim (Index 6):
The nozzle for laser processing head according to  claim 1 , wherein the inner circumferential surface of the nozzle tip body is applied with an adhesion inhibiting coating for decreasing adhesiveness of the melted material of the workpiece to the inner circumferential surface.
