Safety and Maintenance of Metal Laser Cutting & Engraving Machine！

Laser safety guidelines for Laser Engraving Machines:

· During machine operation, operators must not leave the machine unattended to avoid unnecessary loss.

· When the machine is in operation, the top cover of the machine must be covered to prevent the laser from deviating and causing harm.

· All parts of the machine must be grounded reliably to prevent static electricity from harming people.

· As this type of laser is invisible, flammable and explosive items are strictly prohibited from being placed near the equipment to prevent laser deviation causing a fire.

· It is strictly prohibited to place any unrelated fully reflective or diffusive objects in the equipment to prevent the laser from directly reflecting onto people or flammable items.

· The use of hands to push or pull trolleys or beams is prohibited.

· If the machine malfunctions or catches fire, the power supply must be immediately cut off.

Users must strictly comply with the above regulations, otherwise, if there is personal injury or damage to the machine, the manufacturer will not be held responsible.

Routine maintenance tasks

As a precision instrument, maintenance and upkeep are crucial for the longevity of the laser engraving machine and ensuring processing accuracy.

(1) Ensure the reliability of the device’s ground wire and proper grounding.

(2) It is necessary to ensure the cleanliness of the cooling circulating water, which should be changed frequently, twice a week.

If the equipment is not used for an extended period, drain the water and maintain the water temperature to prevent overheating. (If possible, use pure water.)

(3) Avoid cooling water from freezing in low-temperature environments to prevent the laser from cracking due to freezing.

(4) The machine must be kept clean, especially the optical and motion systems. The guide rails and crossbeams should be wiped regularly and coated with a thin layer of lubricating oil to prevent rust. (Use degreased cotton to wipe and apply sewing machine oil.)

(5) Maintenance of optical equipment

After prolonged use, especially with organic material, smoke and dust may accumulate on the optical lenses (reflective mirrors and focusing mirrors), which can affect laser power, lens lifespan, and engraving results. Wipe the lenses with lens paper or degreased cotton and medical alcohol in a gentle manner. Do not use rough materials or touch the lenses.

Cleaning method for the focusing mirror: First, unscrew the mirror barrel from the laser tube carefully to prevent dropping and damage. Then blow away the surface dust and gently wipe with degreased cotton dipped in alcohol.

Note:

Do not wipe back and forth, and do not use rough materials to wipe the lenses. The lens surface is coated with a special metal film, and damage to the film will lead to a significant decrease in laser energy.
