20W/30W/50W Closed Fiber Laser Marking Machine

The fully enclosed laser marking machine features a fully enclosed safety enclosure, which effectively prevents contamination and odors during the processing. Utilizing laser marking technology, it employs a non-contact processing method, eliminating hazardous factors such as sparks during operation and providing a safer working environment. With an integrated structure and an air-cooling system, it reduces optical pollution and offers high efficiency with minimal maintenance requirements.

The fully enclosed safety enclosure, combined with an exhaust fan, completely removes smoke and odors generated during processing, minimizing indoor air pollution. Equipped with an electric lifting scale and a lifting platform, it allows for easy adjustment of the focal length based on the height of the product being processed, making it suitable for marking products of various heights. Additionally, it can be optionally fitted with a rotary axis for processing 3D products.

Usage Steps of a Fully Enclosed Fiber Laser Marking Machine

Startup

1. Check whether the power cord is correctly connected and in good condition, and whether it is properly grounded.
2. Connect the main power supply, turn on the main power switch, and release the emergency stop switch to put it in the released state.
3. Turn on the computer and enter the marking software.

Marking

1. Place the workpiece on the marking table and position it properly.
2. Turn on the laser power button, and then press the galvanometer mirror switch button. All fans should start running.
3. Call up the pattern or file to be marked, press the red light switch button, adjust the lifting worktable until the two red light areas overlap. At this time, it is the optimal focal length for laser marking.
4. Start marking, and adjust parameters such as the marking speed, frequency, and laser power as needed.

Shutdown

1. After marking is completed, turn off the power of each component: the laser switch, the galvanometer mirror switch, the red light switch, and the key switch.
2. Exit all computer programs and turn off the computer.
