6. How to maintain the laser cutting machine daily?

Maintenance of metal laser cutting machine

I. Replacement of water and cleaning of water tank

The price of laser cutting machine is usually very high, ranging from hundreds of thousands to millions. Therefore, extend the service life of the laser cutting machine as much as possible to save production costs and win greater benefits. This is an important laser cutting machine for daily maintenance. The stability and normal operation of the machine can not be separated from normal operation and daily maintenance. The following will introduce the daily maintenance of laser cutting machine:

The water quality and temperature of circulating water directly affect the service life of laser tube. It is recommended to use pure water and control the water temperature below 35℃. If the temperature exceeds 35℃, it is necessary to replace the circulating water or add ice cubes to the water to reduce the water temperature (users are advised to choose a cooler or use two water tanks).

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

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

Cleaning the water tank: firstly, turn off the power supply, unplug the water pipe at the water inlet, let the water in the laser pipe 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, put the water pump back into the water tank, insert the water pipe connected to the water pump into the water inlet, and tidy up the joints. Turn on the water pump separately and run for 2-3 minutes (make the laser tube full of circulating water).

Second, the fan cleaning

Long-term use of the fan will accumulate a lot of solid dust in the fan, which will make the fan produce a lot of noise, which is not conducive to exhaust and deodorization. When the suction of the fan is not enough to exhaust smoke, first turn off the power supply, remove the air inlet pipe and air outlet pipe on the fan to remove the dust inside, then turn the fan upside down and pull the blades inside until it is clean, and then install the fan.

Third, the cleaning of lenses.

(It is recommended to clean before going to work every day, and the equipment must be turned off. )

There are three mirrors and 1 focusing mirrors on the laser cutting machine (1 mirror is located at the emission outlet of the laser tube, that is, at the upper left corner of the machine, the second mirror is located at the left end of the beam, the third mirror is located at the top of the fixed part of the laser head, and the focusing mirror is located in the adjustable lens barrel at the lower part of the laser head). The laser is reflected and focused by these mirrors and then emitted from the laser head. The lens is easily contaminated with dust or other pollutants, resulting in laser loss or lens damage. There is no need to remove the 1 and No.2 lenses when cleaning. Just carefully wipe the mirror cleaning paper dipped in cleaning solution, and wipe it along the center of the lens to the edge. The No.3 lens and the focus lens need to be taken out of the frame, wiped in the same way, and put back as they are after wiping.

Note: 1. The lens should be gently wiped to avoid damaging the surface coating;

2. Handle with care during wiping to prevent falling;

3. When installing the focusing lens, please keep the concave face down.
