What should I pay attention to after buying a laser cutting machine?


At present, there are many manufacturers of laser cutting machines, and their processing efficiency is also very fast. The diversification of laser cutting machine products meets the needs of customers for different laser cutting machines. The price of laser cutting machines is different, and the configuration of laser cutting machines is different. So what should we pay attention to after buying laser cutting machines. As a professional laser equipment manufacturer, Xintian Laser will answer for you next.

Water replacement and water tank cleaning:

Note: Before the machine starts to work, make sure that the laser tube is full of circulating water. The quality and temperature of circulating water directly affect the service life of laser tubes. It is recommended to use purified water and control the water temperature below 35 ° C. If the temperature exceeds 35 ° C, 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 supply and unplug the water inlet pipe to make the water in the laser pipe automatically flow into the water tank. Next, open the water tank, take the water pump and remove the dirt on the water pump. Third, clean the water tank, replace the circulating water, send the water pump back to the water tank, insert the water pipe connecting the water pump into the water inlet, and clean the joint. Finally, put the pump alone and run it for 2-3 minutes (fill the laser tube with circulating water).

Blower cleaning

Long-term use of the blower will lead to a large amount of solid dust accumulation, generate a lot of noise, and is not conducive to exhaust and deodorization. When the fan has no suction, first turn off the power supply, remove the air inlet and outlet from the fan, remove the dust inside, then turn the fan upside down and pull out the internal blades until they are clean. Finally, install the fan.

Lens cleaning.

In the previous machine description, it is said that there are three reflectors and a focus lens on the laser engraving machine (the first reflector is located at the exit of the laser tube, that is, at the upper left corner of the machine, and the second reflector is located at the left end of the beam, the third reflector is located at the top of the fixed part of the laser head, and the focus mirror is located in the adjustable mirror barrel at the lower part of the laser head). The laser is reflected and focused by these lenses and emitted from the laser head. The lens is easily polluted by dust or other pollutants, resulting in laser loss or lens damage. Do not remove the No. 1 and No. 2 lenses during cleaning. Instead, carefully wipe the lens with cleaning solution along the center of the lens. Edge rotation wipe. The No. 3 lens and the focus lens need to be removed from the frame and wiped in the same way.

Note: First of all, the lens should be wiped gently without damaging the surface coating. Secondly, gently wipe the wiping process to prevent wiping. Third, when installing the focus lens, be sure to keep the concave side downward.

The guide rail is clean.

As one of the core components of the equipment, the guide rail and linear axis have guiding and supporting functions. In order to ensure that the machine has higher machining accuracy, it needs its guide rail, and the straight line has high guiding accuracy and good motion stability. During equipment operation, a large amount of corrosive dust and smoke will be generated during workpiece processing. Soot will deposit on the surface of guide rail and linear axis for a long time, which will have a great impact on the processing accuracy of the equipment. The erosion point is formed on the surface of the linear axis of the guide rail, which shortens the service life of the equipment. In order to make the machine work normally and ensure the processing quality of the product, we must do a good job in the daily maintenance of the guide rail and linear axis. (It is recommended to clean the water tank every two weeks and run it at the time when the equipment must be shut down, clean the water tank and replace the circulating water once a week).

Tighten screws and couplings.

After working for a period of time, the screws and couplings of the movement system will loosen and affect the stability of the mechanical movement. Therefore, during the operation of the machine, it is necessary to observe whether there is abnormal noise or abnormal phenomenon in the transmission parts, and maintain them firmly and timely. At the same time, the machine should use tools to tighten the screws one by one. The first firmness should be about one month after using the equipment.

Optical path inspection.

The light path system of the laser engraving machine is completed by the reflection of the mirror and the focusing of the focusing lens. The optical path of the focusing mirror has no deviation problem, but the three mirrors are fixed by mechanical parts, and the deviation is even more impossible. Although it will not be offset under normal conditions, it is recommended that the user check that the light path is normal before each work at any time.
