Laser cutting machine is a kind of high-power heavy industrial equipment, its good play can help enterprises improve efficiency, the follow-up work is more smooth, but also reduce costs. Therefore, we should pay attention to operation, and usually pay attention to maintenance and servicing to increase the service life of the equipment, which will effectively reduce the impact of the environment on the components, so that they can operate efficiently without failure for a long time.
Laser is one of the core components of laser cutting machine. Its importance is self-evident. We need to develop a more detailed maintenance plan for this purpose, and regularly maintain the equipment according to the Maintenance Manual every day, every week and every month.
Routine maintenance
1) Before starting the machine every day, carefully check the working gas pressure of the laser and the cutting auxiliary gas. If the air pressure is insufficient, please replace it in time.
2) Check whether the cooling water pressure is maintained between 3.5 and 5 bar.
3) Check the temperature of the cooling water. The water temperature required by the selected laser is preferred.
4) Check the height of the oil level in the laser vacuum pump. If it is not enough, add it.
5) Check whether the oil, water and gas circuits of the laser are leaking, and whether the pneumatic components and pipe joints of the vacuum pump and resonator are leaking.
Maintain the laser once a week
1) Check whether there is oil and water in the gas mixing unit of the laser, and if there is, clean it in time; Check the gas drying filter of the laser. If more than 1/4 of the color changes to red or white, replace it, and its normal color is blue.
2) Check whether there are impurities in the filter of the water cooler.
3) Check whether there are impurities in the cooling water circuit of the laser.
4) Check the condensate level in the compressed air separator (located in the air supply unit). Check the oil level of the vacuum pump (under the air supply unit). When the pump is cold, the oil level in the center line of the oil window should be+5mm-0mm, and add oil when necessary.
5) Check the oil level of roots pump. The oil level in the Roots pump gearbox can be seen through the oil window on the end face of the gearbox. When the pump is shut down and kept cold, the oil level should be within+5mm-0mm of the glass centerline, and add htcl2100 oil model if necessary.
How to maintain the laser cutting machine?
Laser maintenance every six months
1) Check whether the cooling water pipe of the laser head is corroded. If so, please handle or replace the pipe in time.
2) Check the oil tank of excitation power supply for oil leakage.
3) Check whether the high-voltage cable is damaged.
4) Check and clean the interior of the laser resonator and all lenses, including the front window mirror, rear view mirror, reflector, etc.
5) After cleaning the lens inside the laser, readjust the output mode of the laser until the correct mode is reached.
6) Replace the vacuum pump oil.
7) Replace roots pump oil.
8) Carefully tighten all plugs to ensure tightness of Roots pump.
9) There is a white plastic plug on the gas transfer drain at the outlet of Roots pump. Clean the plug and coat its inner surface with silicone grease. The purpose of silicone grease is to absorb and capture the physical impurities in the laser circulating gas. (Only use silicon free high vacuum grease, which should be very thin.)
In addition to the daily maintenance of the laser, the machine tool and the cooling fan should also be maintained. If any parts are damaged during the use of the machine, they must be replaced in time to fundamentally ensure the normal production of the machine. It not only protects the machine itself, but also ensures that the laser cutting machine always keeps the ideal cutting effect.
