In recent years, metal laser cutting machines have become increasingly popular in the mechanical industry, and their applications are very extensive, encompassing many industries. Applied in industries such as sheet metal processing, chassis and cabinets, lighting, mechanical processing, and hardware.

But the purchase cost of a laser cutting machine is not low. How can we avoid a decrease in the cutting ability of the cutting machine in daily production?

Reasons for the decrease in cutting ability of metal laser cutting machines

After long-term use, the laser power of the fiber metal laser cutting machine will decay and decrease, which will directly affect the cutting performance. The speed of laser cutting is directly related to the power of the laser, and the higher the power, the higher the cutting speed.

The position of the focal point affects the cutting progress, and the diameter of the focal spot should be as small as possible to produce narrow cutting seams. If the cutting performance decreases, the focus position can be adjusted. The distance between the workpiece and the nozzle also affects the cutting effect. If the distance is too far, it will cause energy waste, while if the distance is too close, it will affect the dispersion of splashed cutting products. In addition, improper operation, prolonged production under load, and prolonged lack of maintenance can all lead to a decrease in the performance of fiber laser cutting equipment and a significant reduction in cutting efficiency.

The cutting efficiency of rust plates will decrease, the effect will be poor, and the scrap rate will be higher. If conditions permit, it is better to reduce the use of rusty plates or treat them when in use.

The biggest damage is actually the explosion of holes during drilling and cutting, which causes pollution to the lens. A polishing machine can be used to remove rust first. If the plate is not a thick plate, the impact below 5mm is not significant, but the quality of the cut product will be affected, and the rejection rate is high.

The cutting effect of uniformly rusted boards is better than that of unevenly rusted boards. Because the overall evenly rusted plate absorbs laser evenly, it can perform good cutting. For materials with uneven rust on the surface, the surface condition of the material should be uniform before cutting.

Preventive measures for reducing the cutting ability of metal laser cutting machines

Comply with general cutting machine safety operating procedures. Strictly follow the laser startup program to start the laser, adjust the light, and test the machine. The fiber optic metal laser cutting machine should be operated by a dedicated person and trained by professionals: the operator must undergo training, be familiar with cutting software, equipment structure, performance, and master relevant knowledge of the operating system. It is very important to execute the switch sequence correctly, be familiar with the buttons on each switch panel, operate the fiber laser cutting machine correctly, and so on.

When the equipment is started, operators are not allowed to leave their positions or entrust someone to take care of them without authorization. If it is indeed necessary to leave, the machine should be shut down or the power switch should be cut off. When any abnormalities are found during the processing, the machine should be immediately shut down, the faults should be promptly eliminated or reported to the supervisor.

Pay attention to the maintenance of the fiber optic metal laser cutting machine. Over time, many parts of the fiber optic metal laser cutting machine will wear and tear, which obviously affects the performance of the processing equipment. Therefore, maintenance is very important. For vulnerable parts, frequent replacement is necessary; Optical components should be wiped clean and kept clean after use; Bearings should be lubricated regularly to maintain driving flexibility and machining accuracy.

From the analysis of the cutting principle of a laser cutting machine, the laser itself cannot become a light source. Heat is only generated when the laser is absorbed on the surface of the processed sheet metal. In the surface condition of materials with or without rust, the laser absorption is different, and the heat generation situation can also be greatly affected.
