How to deal with laser cutting burrs

How does the laser cutting machine technology deal with the problem of burrs? When some customers use the laser cutting machine to process sheet metal, the effect of the workpiece cut is very unsatisfactory, and there are many burrs. Then many customers begin to doubt the quality of the laser cutting machine products, but it is not. During the cutting process of metal laser cutting machine, due to improper operation and technical problems, the processed materials will not produce burrs.

Burrs only occur in metal cutting, and there is no burr problem in non-metallic cutting. How are burrs produced? In fact, burr is the excessive residue particles on the surface of metal materials. If a material has burrs, it can be qualitatively defective. The more burrs, the lower the quality.

The working principle of the laser cutting machine, technical analysis and its burr causes and solutions.

1、 The upper and lower positions of the beam focus deviate. Solution: Adjust the focus position according to its offset position.

2、 The output power of the machine is not enough. Solution: Check whether the laser cutting machine works normally. If it is abnormal, timely repair and maintenance are required. If it is normal, check whether the output value is correct.

3、 The wire cutting speed of the cutter is too slow. Solution: timely adjust and improve wire cutting speed.

4、 The purity of the auxiliary gas of the cutter is not enough. Solution: Explain how to improve the purity of auxiliary gas.

5、 The addition point of the laser beam of the cutting machine has shifted. Solution: Conduct focus debugging and timely adjustment

6、 The laser cutting machine is unstable due to too long operation time. Solution: Turn off the machine and restart it and let it rest.

The metal laser cutting machine is a precision machine, and its operation is also a fine work. Often a data error will cause its work to run abnormally. Therefore, it should be strict and fine in work to reduce and avoid errors.

The main causes of burrs in sheet metal processed by laser cutting machine; When the laser cutting machine is processing the workpiece, the high energy generated by the laser beam illuminating the workpiece surface makes the workpiece surface vaporize rapidly and evaporate to achieve the purpose of cutting. But there is a core device that we must pay attention to, namely, auxiliary gas. The auxiliary gas is used to blow off the slag on the surface of the workpiece after the surface of the workpiece is gasified. If the auxiliary gas is not used, the slag will form burrs attached to the cutting surface after cooling. This is the main cause of burrs.

Another reason is the quality of the equipment itself, as well as the parameter setting factor. After the customer purchases the laser cutting machine, the professional operator must debug the equipment.

Solution to burr of sheet metal processed by laser cutting machine;

1. Be sure to equip air compressor and use auxiliary gas for cutting.

2. Ask a professional operator to debug the parameters of the laser cutting machine until they are normal.
