laser cutting-Stainless steel
The high-energy density laser beam is used to heat the workpiece, so that the temperature rises rapidly, reaching the boiling point of the material in a very short time, and the material begins to vaporize and form vapor. The jetting speed of these vapors is very high, and at the same time as the vapor jets, cuts are formed in the material.

It is one of the common phenomena in fiber laser cutting machine processing. In laser cutting processing, the irregular parts such as sharp corners and burrs that sometimes appear at the transition of the workpiece surface are burrs.
When many companies use a laser cutting machine for cutting, they find that the cut workpiece has a lot of burrs and the quality is very unsatisfactory, so they suspect that there is a problem with the quality of this cutting machine. Is this really the reason? In fact, it is not necessarily. In most cases, the burrs are not caused by the quality problems of the laser cutting machine itself, but because of the wrong operation method of the operator or the improper maintenance of the cutting machine. In addition, there is another main cause of burrs, which is the auxiliary gas problem. During laser cutting, the laser beam irradiates the surface of the workpiece to generate extremely high temperatures, which quickly vaporizes and evaporates the surface of the workpiece, thereby achieving the purpose of cutting metal. The role of the auxiliary gas is to blow off the residual slag on the surface of the workpiece after the workpiece is irradiated and vaporized by the laser beam. If you don't do this, waiting for the slag to cool, it will form a layer of attached burrs on the cutting surface of the workpiece.
Below, we will summarize several common causes of burrs and their corresponding solutions to help readers stay away from laser cutting burrs.
Causes and solutions of laser cutting machine burrs
Reason 1: There is a deviation in the upper and lower positions of the focus of the beam.
Solution: Adjust the position of the focus and adjust it according to the offset position it produces.
Reason 2: The output power of the machine is not enough.
Solution: Check whether the laser cutting machine is working properly. If it is abnormal, it needs timely repair and maintenance. If it is normal, check whether the output value is correct.
Reason 3: The wire cutting speed of the fiber laser cutting machine is too slow.
Solution: Adjust and increase the wire cutting speed in time.
Reason 4: The purity of the auxiliary gas of the fiber laser cutting machine is not enough.
Solution: Explain how to improve the purity of the auxiliary gas.
Reason five: The laser beam of the fiber laser cutting machine has an offset.
Solution: Debug the focus and make adjustments in time.
Reason 6: The instability of the fiber laser cutting machine operating time is too long.
Solution: Turn off the machine and restart it and let the machine rest.
