Detailed Maintenance Method Of Fiber Laser Machine Source

Laser cutting machine is a high-power heavy industrial equipment. Its good play helps the enterprise to upgrade its efficiency, make the follow-up work more smoothly, and reduce the cost at the same time. Therefore, attention should be paid during operation, and maintenance should be paid to in order to increase the service life of the equipment, effectively reduce the impact of the environment on various components, and make them operate with high efficiency and trouble free for a long time.

The laser is one of the core accessories of the fiber laser cutting machine. Its importance is self-evident. We need to make a more detailed maintenance plan for it and maintain the equipment regularly according to the "maintenance manual" every day, week and month.

Daily maintenance of laser

1) Before starting up every day, carefully check the pressure of laser working gas and cutting auxiliary gas. If the gas pressure is not enough, replace it in time.

2) Check that the cooling water pressure is kept between 3.5 and 5 bar.

3) Check the temperature of the cooling water, and the temperature of the water required by the selected laser is preferred.

4) Check the oil level in the laser vacuum pump. If it is not enough, add it.

5) Check whether the oil circuit, water circuit and gas circuit of the laser are leaking, and whether the pneumatic components and pipe joints of the vacuum pump and resonant cavity are leaking.

Weekly maintenance of laser

1) Check whether there is oil and water in the gas mixing unit of the laser, and if so, clean it in time; Check the laser gas drying filter. If more than 1 / 4 of the color turns red or white, it needs to be replaced. Its normal color is blue.

2) Check the filter of the chiller for impurities.

3) Check the laser cooling water circuit for impurities.

4) Check the condensate water 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 in cold state, the oil level should be between + 5mm-0mm in the middle line of the oil window, and refuel when necessary.

5) Check the oil level of roots pump. The oil level in the gearbox of roots pump can be seen through the oil window on the end face of the gearbox. When the pump is turned off and in cold state, the oil level should be between + 5mm-0mm of the middle line of the glass. If necessary, add htcl2100 oil.

Semi annual maintenance of laser

1) Check whether the cooling water pipeline of the laser head is corroded. If so, deal with it or replace the pipeline in time.

2) Check whether the oil tank of excitation power supply leaks oil.

3) Check whether the high-voltage cable is damaged.

4) Check and clean the inside of the laser resonator and all lenses, including front window mirror, tail mirror, reflector, etc.

5) After the internal lens of the laser is cleaned, the light output mode of the laser shall be readjusted until the correct mode is reached.

6) Replace the vacuum pump oil.

7) Replace roots pump oil.

8) Carefully tighten all plugs to ensure the air tightness of roots pump.

9) There is a white plastic plug on the gas shunt discharge at the outlet end of roots pump. Clean the plug and coat its inner surface with silicone grease. The purpose of this silicone grease is to adsorb and capture the physical impurities in the circulating gas of the laser. (only silicon free high vacuum grease can be used, and the coating should be very thin).

While doing a good job in the daily maintenance of the laser, it is also necessary to maintain the machine tool and cooling fan. If any parts and components are found damaged during the use of the machine, they must be replaced in time, so as to fundamentally ensure the normal production of the machine, which is a kind of protection for the machine itself, It can also ensure that the metal laser cutting machine always maintains an ideal cutting effect.
