1. An operating head, in particular for a laser machine, comprising: a base ( 12 ) rotatably associable to a movable structure of a laser machine around a first axis (A), a rotating body ( 20 ) rotatably supported by the base ( 12 ) rotatable around a second axis (B), a terminal body ( 30 ) provided with an operating end ( 37 ), which is supported by the rotating body ( 20 ) movable along the direction of the above-said second axis (B), a first motor ( 36 ) to control the rotation of the rotating body ( 20 ) around said second axis (B), and a second motor ( 42 ) to control the movement of the terminal body ( 30 ) along said second axis (B), characterised in that said operating end ( 37 ) is mounted on said terminal body so that is able to translate along a third axis (C) perpendicular to said first axis (B) and in that said head comprises also a third motor ( 53 ) to move said operating end ( 37 ) along said third axis (C).
