Maintenance and cleaning skills of laser cutting machine lens and water tank

1. Water replacement and water tank cleaning

1. Suggestion: Clean the water tank and replace the circulating water once a week

2. Note: Make sure that the laser tube is filled with circulating water before the machine works.

The water quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water and keep the water temperature below 35°C. If it exceeds 35℃, the circulating water needs to be replaced, or ice cubes are added to the water to reduce the water temperature (it is recommended that the user choose a cooler or use two water tanks).

Clean the water tank: first turn off the power, unplug the water inlet pipe, let the water in the laser tube automatically flow into the water tank, open the water tank, take out the water pump, and remove the dirt on the water pump. Clean the water tank, replace the circulating water, restore the water pump back to the water tank, insert the water pipe connected to the water pump into the water inlet, and arrange all joints. Power on the water pump alone and run for 2-3 minutes (make the laser tube full of circulating water).

2. Cleaning of the lens

1. It is recommended to clean before working every day, and the equipment must be turned off

There are 3 reflecting mirrors and 1 focusing mirror on the engraving machine (No. 1 reflecting mirror is located at the emission exit of the laser tube, which is the upper left corner of the machine, and No. 2 reflecting mirror is located at the left end of the beam , No. 3 reflector is located on the top of the fixed part of the laser head, and the focusing mirror is located in the adjustable lens barrel under the laser head. The laser is reflected and focused by these lenses and emitted from the laser head. The lens is easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. Do not remove the lens when cleaning the No. 1 and No. 2 lenses. Just place the lens wiping paper dipped in the cleaning solution carefully along the center of the lens. Rotating edge wipe. The No. 3 lens and the focusing lens need to be taken out of the frame, wiped in the same way, and put back as they are after wiping.

2. Note: ①The lens should be wiped gently, and the surface coating should not be damaged; ②The wiping process should be handled gently to prevent falling; ③Please keep the focusing lens when installing Concave face down.
