1、 Inspection of optical path

The optical path system of the laser cutting equipment is jointly completed by the reflection of the reflector and the focusing of the focusing mirror. In the optical path, the focusing mirror does not have the problem of deviation, but the three reflectors are fixed by the mechanical part, which has a high possibility of deviation. Although usually there is no deviation, it is recommended that the user must check whether the optical path is normal before each work.

2： Cleaning of lenses

(It is recommended to clean the equipment before working every day, and the equipment must be turned off)

There are 3 mirrors and 1 focusing mirror on the laser machine (No. 1 mirror is located at the emission outlet 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, No. 3 mirror is located at the top of the fixed part of the laser head, and the focusing mirror is located at the adjustable lower part of the laser head

In the lens barrel), the laser is emitted from the laser hair after being reflected and focused by these lenses. The lens is easy to be stained with dust or other pollutants, which may cause laser loss or lens damage. Do not remove No. 1 and No. 2 lenses when cleaning. Just carefully place the lens cleaning paper dipped with cleaning solution along the

The lens is swivelled from the center to the edge. 3 # lens and focusing lens need to be taken out of the lens frame, wiped with the same method, and then replaced as is after wiping.

Note: 1. The lens should be gently wiped to avoid damaging the surface coating; 2. The wiping process shall be handled with care to prevent falling; 3. When installing the focusing mirror, be sure to keep the concave side downward.

  

3、 Fan cleaning

If the fan is used for a long time, a lot of solid dust will accumulate in the fan, which will make the fan produce a lot of noise, and is not conducive to exhaust and deodorization. When the suction of the fan is insufficient and the smoke exhaust is not smooth, first turn off the power, remove the air inlet pipe and air outlet pipe on the fan, and remove the

Dust, then turn the fan upside down, pull out the fan blade inside until it is clean, and then install the fan.

4、 Cleaning of guide rail

(It is recommended to clean every half month and shut down the machine)

As one of the core components of the equipment, the guide rail and linear shaft play a guiding and supporting role. In order to ensure that the machine has a high processing accuracy, its guide rails and straight lines are required to have a high guidance accuracy and good motion stability. During the operation of the equipment

A large amount of corrosive dust and smoke will be produced during the processing of machined parts, which will be deposited on the surface of guide rail and linear shaft for a long time, which has a great impact on the processing accuracy of the equipment, and will form corrosion spots on the surface of linear shaft of guide rail, thus shortening the service life of the equipment. To make

The machine works normally and stably to ensure the processing quality of the product. Daily maintenance of the guide rail and linear shaft should be done carefully.

Note: Please prepare dry cotton cloth and lubricating oil for cleaning the guide rail

5、 Fastening of screws and couplings

After the movement system works for a period of time, the screws and couplings at the movement joints will become loose, which will affect the stability of the mechanical movement. Therefore, during the operation of the machine, it is necessary to observe whether there are abnormal noises or abnormal phenomena in the transmission parts, and if any problems are found, it is necessary to strengthen and maintain them in time. Simultaneous machine

The screws should be tightened one by one with tools after a period of time. The first time of firming shall be about one month after the equipment is used.

6： Water tank cleaning and water replacement

Suggestion: clean the water tank and replace the circulating water once a week

Note: Make sure that the laser tube is full of circulating water before the machine works.

The quality and temperature of circulating water directly affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 35 ℃. If the temperature exceeds 35 ℃, it is necessary to replace the circulating water, or add ice to the water to reduce the water temperature, (it is recommended that the user select a cooler or use two water tanks). Clean the water tank: first turn off the power, unplug the water inlet pipe, and let the water in the laser pipe flow into the water tank automatically. 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 to the water tank, insert the water pipe connecting the water pump into the water inlet, and sort out the joints. Power on the water pump separately and run it for 2-3 minutes (fill the laser tube with circulating water).
