The composition of the laser cutting head

Composition

Collimation component: Converge the divergent light transmitted from the optical fiber, and straighten or collimate it. The collimation component also includes a collimation centering part and a water cooling part.

Focusing component: It is placed in the body to focus the collimated parallel laser beam. The focus position can be changed through the focusing part of the focusing component to meet the needs of cutting different materials and different thickness plates.

Protective mirror box: used to isolate the outside world from the internal optical path of the cutting head, ensure the optical path is sealed, prevent dust and impurities from entering the optical path, and extend the service life of the optical fiber cutting head.

Sensor and control box: The distance between the cutting head and the surface of the workpiece can be kept stable for a long time and reliably, and the best cutting quality can be guaranteed.

Cutting nozzle: installed at the front end of the cutting head, it is the m channel for the laser beam and the auxiliary gas. The auxiliary gas forms a high-speed air flow after passing through the inner cavity of the cutting nozzle. Blow away the molten material to achieve the purpose of cutting.

Maintenance

♦ Before going to get off work, use a brush to clean the dust, and then use a dust-free cloth with a small amount of alcohol to clean the entire surface of the cutting head (please be careful not to use Air blow).

♦ Before cutting, check whether the light comes out from the center of the nozzle, otherwise, please re-dimming and calibrate.

♦ Check the roundness and cleanliness of the nozzle before cutting, and clean the nozzle.

♦ Check whether the protective lens is clean every day, otherwise, please clean the protective lens with isopropanol or analytical alcohol (alcohol content above 99.5%), clean and clean without leaving water marks.

♦ Check the ceramic ring, SMA wire, SMA pin, and preamplifier every day for looseness and foreign matter. Please tighten and clean.
