Laser cutting machine maintenance and cleaning skills


Laser cutting is the laser beam irradiated to the workpiece surface through the release of energy to melt and evaporate the workpiece, in order to achieve the purpose of cutting and engraving process. With high precision, fast cutting, and not limited to the cutting pattern limit, automatic typesetting save materials, smooth incision, low processing costs, will gradually improve or replace the traditional cutting process equipment. But in daily work, it is also necessary to maintain the laser cutting machine, in order to make it play a better performance advantage.


Water replacement and water tank cleaning:

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

Note: The laser tube must be filled with circulating water before the machine works.


The water quality and temperature of the circulating water of the laser cutting machine will affect the service life of the laser tube, so it is necessary to use pure water, and control the water temperature below 35℃. If the temperature exceeds 35℃, the circulating water should be replaced or ice should be added to the water to reduce the temperature of the water (it is recommended that the user choose the cooling machine, or use two water tanks).


Cleaning the water tank: First turn off the power supply, unplug the water inlet pipe, let the water in the laser tube automatically flow into the water tank, and open the water tank to take out the water pump, remove the dirt on the water pump.

After the water tank is cleaned, replace the circulating water, and the water pump is restored to the water tank, and then the water pipe connected to the water pump is inserted into the water inlet, after sorting out the joints, the water pump is powered separately, and run for 2-3 minutes (so that the laser tube is full of circulating water).

There are 3 mirrors and 1 focusing mirror on the engraving machine (No. 1 reflector is located at the emission outlet of the laser tube, that is, the upper left corner of the machine, No. 2 reflector is located at the left end of the beam, No. 3 reflector is located at the top of the fixed part of the laser head, and the focusing mirror is located in the adjustable mirror barrel at the lower part of the laser head). The laser is reflected and emitted from the laser head through these lenses.

Because the lens is easily contaminated with dust or other pollutants, resulting in laser loss or lens damage, so No. 1 and No. 2 lenses do not need to be removed when cleaning, just dip in the cleaning liquid wiping paper carefully along the center of the lens to the edge of the rotary wipe. No. 3 lens and focusing lens need to be removed from the frame, wiped in the same way, and then put back in the original form.
