When the laser nozzle reaches a first setting position before the endpoint on the cutting path, the relative movement velocity of the workpiece and the laser nozzle is reduced to a first established velocity.

The invention relates to an arrangement for recognizing a laser machining nozzle (12) when inserting the laser machining nozzle (12) in a laser machining head (4).

Laser cutting process implementing such a nozzle.

Laser cutting process implementing such a nozzle.

Described is a laser machining nozzle (6) for a laser machining device that includes a detection unit for detecting radiation in a process zone defined by the laser machining nozzle (6).

A laser machining nozzle (4a) is provided or using with a capacitive distance control between the laser machining nozzle and the workpiece (8).

Eliminating the use of laser nozzle inserts, the laser nozzle uses an inner tip (140) that is less subject to damage from the welding process.

Provided is a laser processing apparatus which can judge whether a nozzle attached by nozzle replacement is a nozzle that meets process conditions or not.

The invention relates to a device (13) for replacing a laser machining nozzle (12) on a laser machining head.

The invention relates to a universal nozzle (16) for a laser cutting machine and to a laser cutting machine for use with the universal nozzle (16).

The laser cutting head (2) comprises a nozzle receiving device (7) and a nozzle (D) arranged therein.

Furthermore, the nozzle assembly includes a laser that emits a laser beam that is transmitted through the inner passage.

An elongate nozzle hole is laser ablated in the nozzle plate material co-axial with the fluid chamber.

The laser processing apparatus is provided with a nozzle information storage section (114) and a nozzle judgment processing section (118).

The hand held laser includes a body (104), handle (102), and nozzle assembly.
