Why do burrs occur during metal cutting and how to avoid them
Updatetime: 2021-08-03 16:35View:
Fiber laser cutting machines have been widely used in the metal processing industry, and their cutting products have high efficiency and good quality. But sometimes, when the operator performs sheet metal cutting, some burrs will be generated. Many people think it is a problem with the cutting equipment, but it is not.
As long as the fiber metal laser machine is operated correctly in the cutting process, there is generally no problem, and the cutting effect of the workpiece will be very good. But if you have a burr problem when you use a laser machine to cut sheet metal, you need to find out the specific cause in time and get a solution.

How do burrs occur when cutting metal?

Burrs are simply excess residue particles on the surface of a metallic material.When the laser cutting machine is processing the workpiece, the energy generated by the laser beam shining on the surface of the workpiece vaporizes and evaporates to achieve the purpose of cutting. But here's a device that we're going to pay attention to, which is the gas.
 
The gas is to blow off the slag on the surface of the workpiece after gasification of the irradiated surface of the workpiece. If the gas is not used, the slag will form burrs attached to the cutting surface after cooling. The purity of the gas can also affect the quality of cutting, when the gas purity is not enough, there will also be such a problem, it is necessary to replace the gas with higher purity for cutting. 

How to avoid burrs when cutting metal?

If you want to avoid burrs when cutting metal, in addition to the auxiliary gas conditions mentioned above, there are other points that need to be paid attention to.
Focus issues.
The focus position of the laser is not correct. This problem can be solved by adjusting the focus.
Laser output power.
First of all, check whether the laser is normal. On the premise of confirming the normal operation of the laser, further check whether the output power of the laser matches the required power of the plate. If not, it needs to be adjusted.
Cutting speed.
Cutting speed is too slow will also cause burr at the bottom of the cutting surface, at this time, it is necessary to speed up the cutting speed.
Working time of carbon steel laser cutting machine.
When the machine works continuously for more than a certain period of time, such problems may also occur. At this time, you need to restart the machine to try.
 
To obtain a good metal cutting effect, it is very important to choose a high-quality fiber laser cutting machine. When you choose a metal cutting machine, it is necessary to carefully understand the machine configuration and the company's technical service. Only good machines can bring higher benefits to your shop.
