In the process of using fiber laser cutting machine, how to better play the function of the equipment and maximize the working efficiency of the equipment has always been a problem for enterprises to think about. How to ensure that the fiber laser cutting machine maintains a high quality cutting state? Let's take a look at it.

 

1. Water protection should be checked and cleaned frequently. Cooling water can not be washed out. Water protection float switch or water protection float switch is not reset. Short-circuit method cannot be used to solve the urgent need. The cooling water quality should be good, and the aluminum oxide of the nozzle should be too severe. When used for a period of time, the water in the water pump and the water pipe and the water protection should be cleaned as scheduled, otherwise the laser tube will burst or the cold head will fall off.

 

2. The laser tube installation fulcrum of the laser cutting machine should be reasonable. The fulcrum should be at 1/4 of the total length of the laser tube. Otherwise, the laser tube spot pattern will be deteriorated. Some working spots will become a few spots for a period of time, causing the laser power to drop. Meet the requirements, resulting in constant change of management.

 

3, focusing mirror and mirror inspection, work for a while, the frame will have a fever, the surface of the lens will be discolored and rusted; the film peeling is the object to be replaced, especially for many customers using atmospheric pumps and air compressors, so in focus Water is quickly accumulated on the lens, so it is necessary to check the cleaning and quality of the optical path system of the lens (laser tube light exit) on time.

 

4. The suction device should be inspected and cleaned on schedule, and the fan duct should be cleaned up. Otherwise, a lot of smoke and dust can not be discharged, and the lens and the laser tube are seriously and quickly contaminated, so that the mechanical and electronic components are easily oxidized and the contact is not good.

 

5, the cooling system should be grounded, often clean the water tank and waterway, the temperature control point of the refrigeration temperature control water tank should be fair, otherwise the laser tube will be easily damaged and the dew condensation power will drop, the cold head of the tube will fall off, the service life will be greatly shortened, and sometimes it will not work, resulting in Constantly changing the tube.

 

6, the working environment of the laser cutting machine can not be too bad, if the ambient temperature is higher than 30 degrees, below 18 degrees, too much dust, severe air pollution, so the machine is severely damaged, the failure rate is rising; the electrical accessories in the humid environment It is easy to go wrong. Therefore, we especially remind customers to improve the working environment and often maintain the machine.

 

7. The working current of the laser tube should be fair, and it can not work in the light intensity of 90-100 for a long time; it is necessary to apply laser and save laser energy in a fair way; the optical path system should be clean and accurate, otherwise the laser tube will be prematurely aged and cracked, so the laser machine works. The time intensity should be adjusted at 50-60%, and then the working speed is adjusted according to the material, so that the laser tube is in the best working condition.

 

8. The power grid should be matched. The power distribution and contact points of all departments of the whole equipment should be good (fan, water cooler, laser machine, laser power supply, computer should be powered independently).
