1.Daily maintenance of the laser cutting machine

A laser cutting machine is a high-precision device that requires routine maintenance to ensure its proper functioning and prolong its lifespan. The following are the daily maintenance steps of the laser cutting machine:

1.1 Clean the optical lens:

The optical system of the laser cutting machine is usually composed of lenses, reflectors, and focal length mirrors, etc. These parts are easily affected by dust, grease, and stains. These parts need to be wiped gently with a special wipe or pure cotton cloth every day to maintain their cleanliness.

1.2 Cleaning the workbench:

The workbench of the laser cutting machine is usually composed of an adsorption plate and a steel mesh. These parts will generate dirt such as cutting residues and smoke during use and need to be cleaned regularly. Use a cleaning cloth and detergent to wash the work surface daily to ensure it is clean and level.

1.3 Check the cooling system:

The laser of the laser cutting machine needs to dissipate heat through the cooling system to avoid damage to the laser due to overheating. Check daily whether the cooling water is sufficient and whether the cooling fan is working properly to ensure the normal operation of the cooling system.

1.4 Check the gas system:

The gas system of the laser cutting machine usually includes gas sources such as oxygen and nitrogen, which are used to assist in cutting and cleaning the cutting area. Check whether the gas source is sufficient and whether the gas pipeline is unblocked every day to ensure the normal operation of the gas system.

1.5 Check the electrical system:

The electrical system of the laser cutting machine includes components such as a power supply, cables, and control systems. It is necessary to check whether there are abnormalities in these components every day, such as looseness, aging, etc., and deal with them in time.

1.6 Record the maintenance situation:

It is necessary to record the maintenance situation every day, including cleaning, inspection, and replacement of parts, etc., to facilitate future maintenance and management.

2.Weekly maintenance of the laser cutting machine

Here are some weekly maintenance steps that are typically required:

2.8 Oil and water in the gas mixing unit:

Whether the oil and water in the gas mixing unit in the laser have been cleaned up in time.

2.9 Laser gas drying filter:

Whether the red or white portion of the laser gas drying filter has exceeded 25%.

2.10 Filter:

Check if the impurity in the filter of the chiller cleaned.

2.11 Cooling water circuit:

Check if the impurity in the laser cooling water circuit cleaned.

2.12 Condensed water level:

Check if the condensed water level in the compressed air separator (located in the air source unit) reasonable.

2.13 Pump oil level:

When the pump is in a cold state, the oil level of the vacuum pump under the air source unit should be between the 5mm-0mm area of the middle line of the oil window.

2.14 Roots pump:

Check the oil level in the gearbox of the Roots pump through the oil window on the end face of the gearbox. When the pump is cold, the oil level should be in the range of 5mm-0mm from the middle line

The specific maintenance steps may vary from model to model, and it is recommended to find relevant information in the operation manual to ensure correct maintenance operations.

3.Semi-annual maintenance of the laser cutting machine

Laser cutting machines need more in-depth maintenance every six months to ensure long-term stable operation of the equipment.

3.1 Replacing the cutting head:

The service life of the laser cutting head is generally within a few thousand hours and needs to be replaced regularly. During the semi-annual maintenance period, the wear degree of the cutting head can be checked. If the wear is excessive, it needs to be replaced in time.

3.2 Replace the light source:

The light source of the laser cutting machine also needs to be replaced regularly to ensure cutting quality and stability. During the semi-annual maintenance period, the service time of the light source can be checked. If the service life has been reached, it needs to be replaced in time.

3.3 Check the guide rail and transmission system:

The guide rail and transmission system have an important influence on the stability and precision of the laser cutting machine. During the semi-annual maintenance period, it is necessary to check the status of the guide rails and the transmission system. If there is any wear or damage, it needs to be repaired or replaced in time.

3.4 Cleaning the cooling system:

The cooling system of the laser cutting machine needs to be cleaned regularly to ensure the cleanliness and flow of the cooling water. Thorough cleaning can be carried out during the semi-annual maintenance period, including changing the water in the water tank and cleaning the water pipes and filters, etc.

3.5 Check the air system:

The air system also has an important impact on the cutting quality and stability of the laser cutting machine. During the half-year maintenance period, it is necessary to check the status of the air system, including checking whether there is any air leakage in the air pipeline, whether the air source is sufficient, and whether the air valve is normal.

3.6 Clean circuit boards and electrical components:

The circuit boards and electrical components of the laser cutting machine need to be cleaned regularly to avoid pollution such as dust or dust accumulation. During the semi-annual maintenance period, a thorough cleaning can be carried out, and the electrical parts can be checked for looseness or damage.

3.7 Cooling water pipeline:

Clean up the corrosion of the laser head cooling water pipeline in time, or replace the corresponding pipeline.

3.8 Fuel tank:

Check if oil leakage in the fuel tank of the excitation power supply (independent source).

3.9 High-voltage cable:

Check if there is a damaged part of the high-voltage cable.

3.10 Mirrors of the laser resonator:

Clean all mirrors of the laser resonator. Including the front mirror, rear mirror, and window mirror.

3.11 Laser lens:

The laser lens adjusts the light output mode of the laser and needs to be adjusted to the correct mode.

3.12 Vacuum pump oil:

Does the vacuum pump oil need to be replaced?

3.13 Roots pump oil:

Does the Roots pump oil need to be replaced?

3.14 airtightness of the Roots pump:

Check the airtightness of the Roots pump to ensure that all screw plugs are tightened and not loose.

3.15 White plastic plug:

Clean the white plastic plug above the gas splitter at the outlet of the Roots pump.

3.16 Gas distributor:

3.17 Gas splitter :

Apply a thin layer of the white plastic plug to the top of the gas splitter at the outlet of the Roots pump.

3.18 Gas shunt:

Adjust the silicone grease coated on the gas shunt at the gas outlet of the Roots pump to ensure that it absorbs and captures the physical impurities in the circulating gas of the laser.

To sum up, the daily maintenance, weekly maintenance, and semi-annual maintenance of the laser cutting machine need to be paid more attention to. While we are maintaining lasers on weekdays, machine tools/coolers and other parts also need corresponding maintenance. Once damaged parts are found during the operation of the machine, repair, and replacement the first time can prolong the service life of the machine and ensure normal operation of the machine. Only when the laser cutting machine can achieve the ideal cutting effect, can the business operation be able to obtain the maximum profit.
