Tips of Reducing Blurr of Aluminum in Fiber Laser Cutting

Time：2022-11-11

With the increasingly fierce market competition and the increasing market demand, aluminum products are widely used in the manufacturing industry, such as automotive parts, electronic products, precision hardware, mechanical equipment accessories and other industries.
Fiber laser cutting machine plays an important role in efficient production of aluminum plate cutting. So how to improve the cutting quality of aluminum plate has become a topic of common concern. Here are several methods to improve cutting quality for your reference.

Auxiliary Gas

The burr of aluminum plate processed by nitrogen is small, soft and easy to remove, but the operation cost is high.
The burr of air cutting is bigger than that of nitrogen, but it is hard to remove and the operation cost is low.
The burr of oxygen cutting is the biggest, which is not easy to use.

According to the quality requirements of the aluminum plate section, the processing gas should be selected reasonably.

Gas Flow

The burr can be reduced by reducing the height of the nozzle and increasing the gas flow when cutting the holes and corners. Return to normal nozzle height when cutting peripheral.
Cut small holes and corners to reduce nozzle height.

Cutting Head

The zoom speed of the old-fashioned processing head is slow, so it is impossible to change the nozzle height at any time during the processing.
But the latest cutting head has fast zoom speed, and is able to maintain the set focus position thought the nozzle height changes.
The nozzle height can be changed to improve the burr of the aluminum plate.

Output Power

According to the thickness of the plate, the burr of the aluminum plate can be reduced by reasonably selecting the power of fiber laser.

  • How To Solve Focus Position Error Of Fiber Laser Cutting

    During laser cutting, there are many factors that cause a change in the relative position between the focus and the processed workpieces surface, including the surface of the workpiece is uneven , workpiece clamping method , geometric error of the machine tool and deformation of the machine tool under load, and the thermal deformation of the workpiece during machining. These will cause the laser focus position deviated from the ideal position (programming position).
