Title:
NOZZLE FOR MACHINING, MACHINING HEAD, AND OPTICAL MACHINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/081765
Kind Code:
A1
Abstract:
In order to improve powder convergence properties without causing irregularities in powder flow flowrate or powder density, this nozzle for machining comprises: an inner cone that encases a light beam path through which light from a light source passes; an outer cone arranged on the outside of the inner cone; a fluid emission flowpath formed in a gap between the inner cone and the outer cone and comprising an emission port opening towards a machining surface; and a fluid guide flowpath having a fluid inlet for fluid. The fluid guide flowpath guides fluid in a direction away from the light beam path, towards the fluid emission flowpath.
