laser cutter engraver Maintenance
how to maintain the laser cutting machine
Laser Cutting machine Maintenance .1). Replacement of water in chiller. (Recommended replace the water every week)
Notice: Before the laser tube working, please make sure water in the tube is full.
It is forbidden to use circulating water of poor quality, because it may affect the laser power seriously and shorten the service life of laser tube. The temperature of the water should be 15-35℃. If the temperature exceeds 35℃, please change the water(the right way of changing the water is to get out of some hot water and fill in cold water) or turn off the machine to cool the water.
2).Exhaust fan cleaning. After a long time, the exhaust fan will be polluted with dusts. Please open the box of the exhaust fan, remove the two pipes, and then get rid of the dust in the fan.
3). Optical mirror and lens cleaning. Users could clean the first mirror and the second mirror directly with lens paper or cotton plus medical alcohol to gently along the central to the edge be careful not to rub with a rough material or contact them. Please clean the reflecting mirror carefully when it is on the machine, otherwise, the ray path must be readjusted!
The third reflecting mirror and the focus lens need to be taken down from the laser head to clean. Unscrew the lens tube from laser head carefully, then blow away surface dust and gently wipe with the cotton dipped alcohol, put them back after cleaning. Before using the mirrors again, please make sure they are dry.
4).Guide rails should be cleaned, and lubricant should be added onto the rail every two weeks.
The materials for cleaning the rail: cotton cloth and lubricant oil
How to clean the rail : push the laser head to one end of the rail ,and use the cotton cloth clean the rail ,after that, add some lubricant oil on the different part of the rail, and then ,push the laser head from one end of the rail to the opposite end, make sure the oil can be symmetrical added on the rail .
5). Tighten the screws and the shaft coupling
After a period of the time, the screws and the shaft coupling maybe loose, and this will affect the stability and mechanical movement of the machine. Tighten the screws and the shaft coupling every two or three months to make the machine work normally.
6). Bearing maintenance.
Using the soft cloth to wipe the dust which on the bearing, and then use the oil suction needle inject the oil into the bearing and slowly roll the bearing.
7). Laser tube maintenance.
The laser tube should avoid generating incrustation which would cause water stemming. If there is incrustation, please clean it with 20% diluted hydrochloric acid.
