When using a laser cutting machine, first, put on protective goggles and gloves to prevent laser injury. Ensure the work area is well-ventilated to avoid harmful gas exposure. After securing the material to be cut, adjust the machine's parameters based on the type and thickness of the metal sheet. Select the appropriate lens and nozzle, and inspect them before starting up to check for integrity and cleanliness. Adjust the cutting head to the correct focal position and check and adjust the nozzle to center it, as these are essential equipment preparation steps.

       Before operation, ensure the workpiece is accurately positioned and no personnel are nearby to prevent accidental injuries. After cutting materials, inspect the cut surface for smoothness and verify the cutting accuracy. Adjust the equipment parameters as necessary for any discrepancies, until the sample meets the requirements. Operators must strictly adhere to the safety operating procedures for the laser cutting machine, be familiar with its structure and performance, and master the relevant knowledge of the operating system.

       Additionally, be mindful of specific considerations: for instance, avoid frequent contact with the harmful element (ZnSe) in the focusing lens of the laser cutting machine, dispose of worn-out lenses properly, and do not discard them carelessly. Moreover, when cutting thin steel plates at corners with a laser, overheating can cause melting at the corners, creating small radii. This maintains high-speed laser cutting and achieves better cutting quality, thereby saving cutting time. The above are the basic steps and precautions for using a laser cutting machine.
