Maintenance Of Metal Laser Cutting Machine

Metal laser cutting machine is a kind of metal material cutting equipment. It is widely used in sheet metal processing, hardware accessories, machinery manufacturing and other industries. The metal laser cutting machine plays an important role in the whole production process. Once there is a problem, it will lead to the production can not function normally, and cause large losses to the whole production process. In order to ensure that the metal laser cutting machine continues to work, reduce the waste of misuse, maintenance overhaul is crucial!

Nowadays, the laser cutting machine is a high-power heavy-duty equipment, its good play to make the subsequent work more smoothly, but also reduce costs. So in the operation of the middle must pay attention to, and usually pay attention to the maintenance and maintenance in order to increase the service life of the equipment, cost savings, to create greater benefits, to ensure good condition.

Cleaning of the guide rail

(It is recommended to clean every half a month, shut down the machine operation) guide rail, linear axis as one of the core components of the equipment, its function is to play a guiding and supporting role. In order to ensure that the machine has a high degree of machining accuracy, the requirements of its guide rail, linear has a high degree of guiding accuracy and good smoothness of movement. Equipment in the operation process, due to the processed parts in the processing will produce a large number of corrosive dust and smoke, these fumes and dust deposited on the guide rail, linear axis surface for a long time in large quantities, the processing accuracy of the equipment has a great impact, and will be formed in the guide linear axis surface etching, shortening the service life of the equipment. In order to make the machine work normally and stably and ensure the processing quality of the products, we should do the daily maintenance of the guide rail and linear axis carefully.

Water replacement and water tank cleaning

Recommendation: Clean the water tank and replace the circulating water once a week.

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

The quality and temperature of the circulating water directly affects the service life of the laser tube, it is recommended to use pure water, and control the water temperature below 35 ° C. If the temperature exceeds 35 ° C, it is necessary to replace the circulating water. If more than 35 ℃ need to replace the circulating water, or add ice to the water to reduce the water temperature, (recommended that users choose a cooler, or use two water tanks).

Cleaning the water tank: first of all, turn off the power, pull out the water inlet water pipe, let the water in the laser tube automatically flow into the water tank, open the water tank, take out the water pump, remove the dirt on the pump. Clean the water tank, replace the circulating water, restore the water pump back to the water tank, insert the water pipe connecting the water pump into the water inlet, and organize the joints. Energize the water pump alone and run it for 2-3 minutes (to fill the laser tube with circulating water).

Fan cleaning

Fan for a long time, will make the fan inside the accumulation of a lot of solid dust, so that the fan produces a lot of noise, but also not conducive to exhaust and odor. When the fan suction is insufficient exhaust smoke is not smooth, first turn off the power, the fan on the air inlet pipe and outlet pipe removed, remove the dust inside, and then the fan upside down, and pull the inside of the wind blade until clean, and then the fan is installed.

Lens cleaning

(It is recommended to clean it before work every day, and the equipment must be in the state of shutdown) There are 3 reflective mirrors and 1 focusing mirror on the metal laser cutting machine, and the laser is reflected and focused by these mirrors and then launched from the laser head. The lens is easily stained with dust or other pollutants, resulting in laser loss or lens damage, No. 1 and No. 2 lenses do not need to remove when cleaning, just dip the cleaning solution of the mirror paper carefully along the center of the lens to the edge of the rotating wipe. 3 lens and focusing mirror need to be taken out of the mirror frame, with the same method of wiping, wipe the same after the completion of the load back to the original can be.

Note: 

1. The lenses should be wiped gently without damaging the surface coating.

2. The wiping process should be held lightly to prevent falling; motion system in the work for a period of time, the movement of the joints of the screws, couplings will produce loosening, will affect the smoothness of mechanical movement, so in the operation of the machine to observe the transmission components there is no rattling or anomalies, found that the problem should be strengthened and maintained in a timely manner.

Inspection of the optical path

Metal laser cutting machine's light path system is by the reflection of the mirror and the focus of the focusing mirror to complete, in the light path of the focusing mirror does not exist offset problem, but the three mirrors are fixed by the mechanical part of the offset is more likely, although usually does not occur offset, but it is recommended that the user each time before the work to be sure to check whether the light path is normal.
