Key Components of a Fiber Laser Cutting Head

A fiber laser cutting head consists of key components such as a protective lens, collimating and focusing lenses, a nozzle, a sensor head, and a ceramic ring.

Protective Lens: The protective lens is a common consumable part used to prevent metal spatter and dust contaminants generated during the cutting process from entering the optical system.

Collimating and Focusing Lenses: The collimating lens adjusts the state of the incident beam, while the focusing lens concentrates the laser beam onto the processing area. Together, they influence beam quality, focusing performance, and cutting performance.

Nozzle: Located at the very front of the cutting head, the nozzle delivers auxiliary gas to create a stable airflow and helps expel molten metal.

Sensor Head: The sensor detects the relative distance between the cutting head and the workpiece and transmits this information back to the control system.

Ceramic Ring: The ceramic ring is installed between the nozzle assembly and the cutting head, playing a role in nozzle positioning, insulation, and coordination with the sensing system.
