Maintenance knowledge of cnc fiber laser cutting machine

The fiber laser cutting machine gathers the laser beam on the surface of the workpiece by outputting a laser beam with high energy density, and instantly realizes materialization and gasification of the device, thereby achieving the effect of automatic cutting. It is not only suitable for the cutting of sheet metal. For the bevel cutting, the cutting of the round tube can achieve high-precision cutting, and the cutting edge is neat and smooth. At the same time, the fiber laser cutting machine is very expensive, and it is usually necessary to pay attention to maintenance and maintenance to increase the equipment. The service life, let us look at how to maintain the fiber laser cutting machine to the fullest.

1. The cooling system should be grounded, often cleaning 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 shortened, and sometimes it will not work. Constantly changing the tube.

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. water protection should always check the cleaning, cooling water can not be washed out of the water protection float switch or water protection float switch is not reset, can not use short-circuit method to solve the urgent need.

4. The suction device should be inspected and cleaned on time, 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. 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 with atmospheric pumps and air compressors, so in focus Water accumulates quickly on the lens, so it is necessary to check the cleanliness and quality of the lens path system on time.

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.

7. The working current of the laser tube should be fair, and it can not be used for 90-100 light intensity 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.
