Abstract
The invention relates to a tool head for machining a workpiece by means of a laser beam (10), which passes through an optical focusing system (2) which is disposed within the tool head and which is carried by a lens mounting (3) and which can be positioned only by displacing the lens mounting (3) relative to the tool head in the direction of the laser beam. The lens mounting (3) is displaced using automatic setting means (8, 9; 23).
Claims24
A tool head for machining a workpiece by means of a laser beam which passes through an optical focusing system which is disposed within the tool head and which is carried by a lens mounting and which can be positioned only by displacement of the lens mounting relative to the tool head in the direction of the laser beam, wherein the lens mounting (3) is displaceable using automatic setting means (8, 9;
- 23) and a space is subdivided by the lens mounting (3) into two pressure chambers (8, 9) which are situated in front of and behind it in the direction of the laser beam and which can be filled in each instance with a fluid for the displacement of the lens mounting (3).
A tool head for machining a workpiece by means of a laser beam which passes through an optical focusing system (2) which is disposed within the tool head and which is carried by a lens mounting and which can be positioned only by displacement of the lens mounting relative to the tool head in the direction of the laser beam, wherein the lens mounting (3) is displaceable using automatic setting means (8, 9;
- 23), the automatic setting means are electrical setting means, and a protective glass (24) is disposed on the beam exit side and at a distance from the optical focusing system (2), in order to seal off the space provided for the optical focusing system (2) and the lens mounting (3) from a space (25) in which a process gas employed for the machining of the workpiece (12) is situated.
