The application of fiber laser cutting machine has brought great changes to the improvement of work efficiency and cutting accuracy for metal manufacturers. The laser head nozzle is installed at the front end of the fiber laser cutting head, which helps to control the auxiliary gas while protecting the focusing lens.

 

The diameter of the nozzle determines the shape of the gas flow entering the incision, the gas diffusion area, and the gas flow rate, which affects the melt removal and cutting stability. The larger the airflow into the incision, the faster the speed, and the better the position of the workpiece in the airflow, the better the ability of the jet to remove the melt.

 

In the actual operation of the fiber laser cutting machine, when the nozzle and the laser output beam are not coaxial, in order to ensure effective cutting and avoid problems such as excessive cutting seam, nozzle damage, and melting on the cutting surface, it is necessary to adjust the laser to the nozzle center. The following is the adjustment method for your reference.

 

Prepare: Scotch Tape, Allen Key

Principle: The left side of the figure is where the laser head is adjusted, and the right figure is the corresponding cross-sectional view. The laser head adjusts the center of the light to move diagonally. Adjust A and B clockwise through the inner hexagonal wrench, and the laser center point will move away from the wrench; for the same reason, adjust A and B counterclockwise, and the laser The center point will move to the side close to the wrench.

Procedures: Stick a piece of scotch tape on the nozzle, set 10%-15% power in the software, then press Pulse/Laser, check whether the laser hole is in center of nozzle.If not in center, please adjust it to center.

Tips: Here is some common adjustment.

For the fiber laser cutting machine operator, the adjustment of the optical path is very important, and its adjustment process is also complicated. Therefore, you must be careful when adjusting the laser light path. Only careful settings can ensure that the fiber laser cutting machine equipment operates with high precision.
