Workers must first sharpen their tools---maintenance of laser generator

The laser cutting machine belongs to high-power heavy-duty equipment, and its good performance will help the enterprise to upgrade efficiently, and the subsequent work can be carried out more smoothly, and thus lower the cost . Therefore, much more attention should be pay to the regular maintenance to increase the service life of the equipment, which will effectively reduce the impact of the environment on various components, so that they are efficient and trouble-free for long-term operation.

Workers must first sharpen their tools. Laser generator, as one of the core components of laser cutting machines, its importance is self-evident, we need to develop a more detailed maintenance plan for it, daily, weekly, monthly, maintain the equipment regularly according to the “Maintenance Manual”.

PART 1 / Daily maintenance

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

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

3) Check the temperature of the cooling water. The temperature required by the laser is preferred.

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

5) Check the oil circuit, water circuit, and gas circuit for leakage, and whether the vacuum pump, the pneumatic components of the resonant cavity, and the pipe joints leak.
PART 2 / Weekly maintenance

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

2) Check the chiller filter for impurities.

3) Check the laser cooling water circuit for impurities.

4) Check the condensate level in the compressed air separator (in the air supply unit). Check the vacuum pump oil level (below the air supply unit). When the pump is in a cold state, the oil level should be between the middle of the oil window +5mm - 0mm, refuel it when needed.

5) Check the roots pump oil level. The oil level can be seen through the oil window on the end face of the gearbox. When the pump is turned off and in the cold state, the oil level should be between +5mm and 0mm in the middle of the glass. Add oil of the type HTCL2100 if necessary.

PART 3 / Six months maintenance

1) Check the cooling water pipeline of laser head for corrosion. If it is, it should be processed or replaced in time.

2) Check if the excitation power supply tank is leaking oil.

3) Check the high voltage cable for damage.

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

5) After the laser internal lens is cleaned, the laser's light output mode should be readjusted until the correct mode is reached.

6) Replace the oil in vacuum pump and roots pump .

7) Carefully tighten all the plugs to ensure the air tightness of the Roots pump.

8) There is a white plastic plug on the gas outlet of the Roots pump, which is cleaned and coated with silicone grease on its inner surface. The purpose of this silicone grease is to adsorb and capture physical impurities in the circulating gas of the laser. (Use only silicon-free high vacuum grease, which is very thin).

In the daily maintenance of the laser generator, the machine tool and the air cooler should be maintained at the same time. If any parts are damaged during the use of the machine, it must be replaced in time to ensure the normal production of the machine. It is a kind of protection for the machine itself, and it can also ensure that the laser cutting machine always maintains an ideal cutting effect.
