How to deal with burr by laser cutting machine technology puzzles everyone. How does burr come into being? What is the reason for the burr of sheet metal processed by laser cutting machine? Let's give you a simple analysis.
How does laser cutting machine technology deal with the burr problem?
When some customers use laser cutting machine to process sheet metal, the effect of the cut workpiece is very unsatisfactory, and there are many burrs. Then many customers begin to doubt the quality problem of laser cutting machine products, which is not the case.
In the cutting process of metal laser cutting machine, due to improper operation and technical problems, the processed materials will produce burrs. Burr only occurs in metal cutting, and there is no burr problem in non-metal cutting.
How are burrs produced? In fact, burr is excessive residue particles on the surface of metal materials. If a material has burrs, the material can be identified as defective. The more burrs, the lower the quality. What is the reason for the burr of sheet metal processed by laser cutting machine? Let's give you a simple analysis.
The working principle of laser cutting machine is analyzed, and the causes and solutions of burr are obtained.
1. There is a deviation in the up and down position of the focus of the beam.
Solution: adjust the position of the focus according to the 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, it needs to be repaired and maintained in time. If it is normal, check whether the output value is correct.
3. The wire cutting speed of the cutter is too slow.
Solution: adjust and improve the wire cutting speed in time.
4. The purity of the auxiliary gas of the cutting machine is not enough.
Solution: explain how to improve the purity of auxiliary gas.
5. The addition point of the laser beam of the cutter is offset.
Solution: debug the focus and adjust it in time
6. Instability caused by long operation time of laser cutting machine.
Solution: shut down the machine, restart and let the machine rest.
Metal laser cutting machine is a precise machine, and its operation is also a fine work. Often, the error of a data will cause its abnormal operation. Therefore, it is necessary to be strict and precise in work to reduce and avoid errors.
Main causes of burr in sheet metal processing by laser cutting machine
When the laser cutting machine is processing the workpiece, the high energy generated by the laser beam irradiating 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, that is, auxiliary gas.
The auxiliary gas is to blow off the slag on the workpiece surface after the workpiece irradiation surface 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 burr formation.
Another reason is the quality problem of the equipment itself, as well as the parameter setting factor. When customers buy laser cutting machines, they must have professional operators 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. Find a professional operator to debug the parameters of the laser cutting machine until it is normal.
