1、 Characteristics of laser cutting machine process:
Compared with the traditional CO2 laser cutting machine, the application of optical fiber laser cutting equipment in metal plate cutting is changed in the 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 external optical path protection gas, and will not be equipped with air compressor and other processing systems;
The laser beam is collimated and focused after reaching the cutting head. Generally, a focus lens with a focal length of 125mm or 200mm can be configured. A protective lens must be installed between the focus lens and the nozzle to prevent the focus lens from being polluted; Fiber laser has good focusing performance, short focal depth, narrower cutting slit width (up to 0.1mm), higher speed, and is suitable for fast cutting of medium and thin plates.
2、 What are the characteristics of bilateral drive of laser cutting machine?
The laser cutting machine with gantry structure has two kinds of motion forms, one is that the gantry moves but the workbench is fixed during processing, and the other is that the gantry is fixed and the workbench moves. For large format, high-speed and high-performance laser cutting machines, the first form is usually adopted, because the workbench moves with the workpiece and is not suitable for high-speed and thick plate cutting. This bilateral drive ensures the force balance of the beam and the synchronous operation of the beam.
The laser cutting machines of some manufacturers are driven by one side of the gantry. The servo motor is installed at one end of the gantry beam, and then the driving force is transmitted to the other end through a long shaft to realize double gear tooth strip transmission and single servo motor drive. Unilateral driving makes the force on both ends of the beam asymmetrical, affecting the synchronization accuracy and reducing the dynamic performance of the machine tool.
