How to Do Maintenance of Metal Fiber Laser Cutting Machine

Reading Time: 3 minutes

The price of laser cutting machines is usually very high, ranging from several hundred thousand to several million. Therefore, the service life of the laser cutting machine should be extended as much as possible in order to better save production costs and win greater benefits. This is an important laser cutting machine for daily maintenance and maintenance. The stability and normal operation of the machine are inseparable from normal operation and daily maintenance.

The following will introduce the daily maintenance of the metal fiber laser cutting machine:

1、Water replacement and water tank cleaning

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 and keep the water temperature below 35°C. If it exceeds 35°C, the circulating water needs to be replaced, or ice cubes are added to the water to reduce the water temperature (it is recommended that the user choose a cooler or use two water tanks).
(Recommendation: Clean the water tank and replace the circulating water once a week)
Note: Make sure that the laser tube is filled with circulating water before the machine works.

Clean the water tank: first turn off the power, unplug the water inlet pipe, let the water in the laser tube automatically flow into the water tank, open the water tank, take out the water pump, and remove the dirt on the water pump. Clean the water tank, replace the circulating water, restore the water pump back to the water tank, insert the water pipe connected to the water pump into the water inlet, and arrange all joints. Power on the water pump alone and run for 2-3 minutes (make the laser tube full of circulating water).

2、Fan cleaning

Long-term use of the fan will accumulate a lot of solid dust in the fan, make the fan generate a lot of noise, and it is not conducive to exhaust and deodorization. When the fan suction is insufficient and the smoke is not smooth, first turn off the power, remove the air inlet and outlet pipes on the fan, remove the dust inside, then turn the fan upside down, and pull the inner blades until they are clean , And then install the fan.

3、The cleaning of the lens

It is recommended to clean before work every day, and the equipment must be turned off.

There are 3 mirrors and 1 focusing mirror on the laser cutting machine (No. 1 mirror is located at the emission exit of the laser tube, which is the upper left corner of the machine, No. 2 mirror is located at the left end of the beam, and No. 3 mirror is located at the laser head fixed At the top of the part, the focusing lens is located in the adjustable lens barrel at the lower part of the laser head. The laser light is reflected and focused by these lenses and emitted from the laser head. The lens is easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. Do not remove the lens when cleaning the No. 1 and No. 2 lenses. Just place the lens wiping paper dipped in the cleaning solution carefully along the center of the lens. Rotating edge wipe. The No. 3 lens and focusing lens need to be taken out of the frame and wiped in the same way. After wiping, they can be replaced as they are.
1. The lens should be wiped gently, and the surface coating should not be damaged;
2. The wiping process should be handled gently to prevent falling;
3.When installing the focusing lens, be sure to keep the concave surface down.
