Abstract
Focused laser light and plasma arc are coaxially disposed to provide a laser machining head which performs a high precision and efficient machining, by reinforcing laser light with plasma arc to form a versatile heat source. For this purpose, in a tip part,of a laser machining head,having optical systems,and,for focusing a laser light,oscillated by a laser oscillator,, a plasma machining head,is mounted coaxially with the optical systems,and,. The plasma machining head,is provided with electrode nozzles,and,connected to a plasma apparatus,and a working gas supply passage,connected to the electrode nozzles,and,so that the laser light,and a plasma arc,are irradiated towards a same machining position,of a machined part
