Compared with the traditional CO2 laser cutting machine, the application of laser cutting equipment in sheet metal cutting is different in external light path, cutting head, auxiliary gas, etc. The laser can be directly transmitted to the cutting head through the optical fiber, and the optical path is stable and reliable to ensure the consistency of the full width cutting of the machine tool. The machine tool does not need the protective gas of the external optical path, and will not be equipped with air compressor and other processing systems. So, what are the characteristics of the bilateral drive of laser cutting equipment?

After the laser reaches the cutting head, it can be collimated and focused. Generally, a focusing lens with a focal length of 125mm or 200mm can be configured. A protective lens must be installed between the focusing lens and the nozzle to prevent the focusing lens from being polluted. Fiber laser has good focusing performance, short focal depth, narrower cutting slit width and higher speed, which is suitable for fast cutting of medium and thin plates.

The gantry type laser cutting equipment has two types of motion: one is that the gantry moves but the workbench is fixed during processing, and the other is that the gantry is fixed but the workbench moves. For laser cutting machines with large format, high speed and high performance, the first form is usually used, because the worktable moving with the workpiece is not suitable for high-speed and thick plate cutting. This bilateral drive ensures that the force on the beam is balanced and the beam operates synchronously.
