When selecting a fiber laser cutting head, it is recommended to consider the following three dimensions: 1. Laser power matching: The applicable power of the cutting head should match the output power of the laser. For example, for equipment with power ratings of 1.5kW, 2kW, 3kW, 3.3kW, and 6kW, a cutting head with the corresponding power range should be selected. 2. Focus adjustment method: Manual focusing is suitable for production scenarios with relatively fixed processing conditions; automatic focusing is suitable for scenarios requiring frequent focus adjustments or processing materials of different thicknesses, reducing manual adjustments. 3. Processing type: Standard planar cutting heads can be selected for flat plate cutting; for pipe, profile, or 3D curved surface processing, corresponding pipe or 3D cutting heads should be selected.
