The main components of the laser cutting machine are circuit system, transmission system, cooling system, light source system, and dust removal system. The main daily maintenance parts are the cooling system (to ensure the constant temperature effect), the dust removal system (to ensure the dust removal effect), the optical path system (to ensure the beam quality), and the transmission system (to ensure normal operation). In addition, a good working environment and correct operating habits are also conducive to extending the service life of the equipment.

1.Maintenance of cooling system

The water inside the cooler needs to be replaced one time a week. The water quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water or distilled water and keep the water temperature below 35°C. If do not change the water for a long time, it is easy to form scale, which will block the waterway, so it is important change the water regularly.

Second, keep the water flowing at all times. The cooling water is responsible for taking away the heat generated through the laser tube. The higher the water temperature, the lower the light output power (15-20°C water temperature is better); If cooling water stops flowing, the tube will burst due to the heat in the laser cavity and even damage the laser power supply . Therefore, it is necessary to check whether the cooling water is unblocked at any time. If water pipe suffered a hard bend (dead bend) or falls off,which makes pump fail, it must be repaired in time to avoid power drop or even equipment damage.

2.Maintenance of dust removal system 

A lot of dust will accumulate in it after the fan is used for a long time, which affects the function of exhaust, deodorization, and also generate noise as well. When the fan is found to have insufficient suction power and poor smoke exhaust, first turn off the power, remove the air inlet and outlet pipes on the fan, remove the dust inside, and then turn the fan upside down and flip the fan blades inside until it is clean. Then install the fan. Fan maintenance should be done about one time one month.

3.Maintenance optical system

After the machine has been working for a period of time, a layer of ash will stick to the surface of the lens due to the working environment, thereby reducing the reflectivity of the lens and the transmittance of the lens, and ultimately affecting the working power of the laser. At this time, use absorbent cotton dipped in ethanol to wipe carefully along the center to the edge of the lens. The lens should be wiped gently, and the surface coating should not be damaged; the wiping process should be handled with care to prevent falling; when installing the focusing lens, be sure to keep the concave surface down. In addition, the use of ultra-high-speed piercing should be minimized at ordinary times, and the use of conventional piercing can extend the service life of the focusing lens.
