6 Tips To Control Burrs By Laser Cutter

Date:2019-08-03 17:28 Write:admin Click:
Laser cutting machine have been common in sheet metal processing. Due to their high work efficiency and high quality of finished products, they have become the standard for sheet metal processing stations. However, some customers use the laser cutting machine to cut out the workpiece burrs, many people think that the quality of the laser cutting machine products, in fact, not quite.
 
In the process of sheet metal processing, the gas purity and parameter setting of the laser cutting machine will affect the processing quality, equipment + gas + parameters, and the adjustment is good, and the cut workpiece is free of burrs.
 
How is the burr generated?
 
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 illuminating the surface of the workpiece vaporizes the surface of the workpiece and evaporates to achieve the purpose of cutting. But there is a device here, we have to pay attention to it, it is gas.
 
The gas is the slag that blows off the surface of the workpiece after the surface of the workpiece is vaporized. If the gas is not used, the slag is cooled and a burr is formed on the cutting surface. Therefore, the purity of the gas is high, and it can be exchanged for a higher quality gas supplier. The purity of the gas is very important. Do not use the cylinder gas, because after two fillings, the purity is not good and 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, the experienced operator must debug the equipment. Therefore, it is necessary to adjust the cutting parameters as much as possible, and the cutting speed of the pneumatic flow focal length is subject to repeated adjustments. The parameters provided by the machine are that the workpieces with high quality cannot be cut.
 
If a piece of material has a burr, then the material can be qualitatively defective, and the more burrs, the lower the quality naturally.
 
Generally speaking, when the laser cutting machine has burrs, it can be checked and solved from the following aspects:
 
1. The output power of the laser cutting machine is not enough.
 
Solution: Check if the laser cutting machine is working properly. If it is not normal, it needs timely repair and maintenance. If it is normal, check if the output value is correct.
 
2. The deviation of the upper and lower positions of the focus of the beam occurs.
 
Solution: Adjust the position of the focus and adjust it according to the offset position it produces.
 
3. The purity of the gas of the cutting machine is not enough.
 
Solution: Change the gas.
 
4. The cutting speed of the cutting machine is too slow.
 
Solution: Adjust the wire cutting speed in time.
 
5. The addition of the laser beam of the cutting machine is offset.
 
Solution: Debug the focus and make adjustments in time
 
6. The instability of the laser cutting machine is too long.
 
Solution: Turn off the machine and let the machine rest.
 
The laser cutting machine is a sophisticated machine. Often a data error will cause its work to be abnormal. Therefore, it is necessary to be strict in the work and reduce errors.
