What is the problem with the laser cutting machine processing workpiece burrs?

The processing effect of the laser cutting machine is appreciated by everyone who has used it, but as a processing machine, it is inevitable that some problems will occur in the processing work. For example, the workpiece processed by the laser cutting machine has many burrs. Why does this happen? The following is the analysis of the editor:

Laser cutting machines are already common in sheet metal processing. Due to the high work efficiency  high cutting quality of finished products, laser cutting machines have become the standard for sheet metal processing stations. However, when some customers use laser cutting machines, they cut off many burrs. Many people think that the quality of laser cutting machines is  the case.

In the process of sheet metal processing, the gas purity  parameter settings of the laser cutting machine will affect the processing quality. The equipment + gas + parameters are adjusted to be optimal,  the cut workpiece is free of burrs.

How do glitches occur? 

In fact, burrs are excessive residue particles on the surface of metal materials. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam irradiating the surface of the workpiece vaporizes  vaporizes the surface of the workpiece to achieve the purpose of cutting. But there is a device here that we should pay attention to, that is, gas.

The gas is to blow off the slag on the surface of the workpiece after the irradiation surface of the workpiece is vaporized. If the gas is  used, after the slag is cooled, burrs will form on the cutting surface. Therefore, the purity of the gas is higher. You can change to a gas supplier with a higher quality. The purity of the gas is very important. Do  use cylinder gas, because after two fillings, the purity is  good  the gas is wasted.

Another reason is the quality of the equipment itself, as well as the parameter setting factors, so when the customer purchases the laser cutting machine , it is necessary for an experienced operator to debug the equipment. Therefore, it is necessary to adjust the cutting parameters to be as good as possible. The air pressure, flow focal length  cutting speed, etc., have to be adjusted many times. The parameters provided by the machine cannot cut high-quality workpieces.

If a material has burrs, the material can be qualitatively defective. The more burrs, the lower the quality. Specifically, when the laser cutting machine has burrs, it can be investigated  resolved  the following aspects 1. The upper  lower positions of the focal point of the beam are deviated.

Solution: Adjust the position of the focus,  adjust it according to the offset position.

2. The output power of the laser cutting machine is  enough.

Solution: Check whether the laser cutting machine works normally. If it is abnormal, it needs timely repair  maintenance. If it is normal, check whether the output value is correct.

3. The wire cutting speed of the cutting machine is too slow.

Solution: Adjust the wire cutting speed in time.

4. The gas purity of the cutting machine is  enough.

Solution: Change gas.

5. The dot of the laser beam of the cutting machine has shifted.

Solution: Perform focus adjustment  timely adjustment

6. Instability due to the long operation time of the laser cutting machine.

Solution: Turn off the machine  restart  let the machine rest.

Fiber laser cutting machine is a precision machine, often a data error will cause its work to run abnormally, so it should be strict in the work to reduce errors.

These are the reasons for the burrs in the laser cutting machine  the corresponding solutions. If you don't know how to solve them, you can take a look.
