Title
(EN) Laser head device
Abstract
(EN)

A laser head device including a nozzle supporting shaft (11) which is formed in the shape of a pipe through which laser beams (LB) pass, characterized in that the shaft is vertically movably supported in a frame of a laser processing apparatus and is rotatable about its axis so that it acts both as a protecting pipe for the laser beams (LB) and as a rotary shaft. The object is to provide a laser head device which is simple, compact and lightweight in comparison with conventional ones.
