In order to strengthen everyone's understanding of laser cutting machine, Xiao Bian sorted out two common problems in sheet metal processing and provided solutions, so that customers can adjust themselves when these production problems really occur.
1. When cutting carbon steel, there are always burrs on the cutting surface?
As we all know, the working principle of the laser cutting machine is to use the energy of light to cut the metal plate. Therefore, when the cutting surface of the sheet metal part has burrs, the first thing to consider is the position of the laser focus. If the position is incorrect, it will lead to the failure to effectively achieve the processing of the sheet metal part. Therefore, the solution is to adjust the focus position of the laser head. If there is no problem with the focus of the laser head laser cutting machine, then the laser power needs to be considered. Since the cutting capabilities of lasers with different powers are different, if the thickness of carbon steel processed exceeds the limit value of laser cutting, the cutting quality will decline linearly. The third thing to check is the auxiliary gas. Generally speaking, only when the purity of the auxiliary gas is higher, the cutting performance of the laser cutting machine will be better. Therefore, the quality of the auxiliary gas should be guaranteed.
2. Why does it sometimes occur that it is not cut through?
The main reason for unstable processing like this is that the nozzle of the laser head does not match the thickness of the processing material. Then the cutting line speed of the laser cutting machine is too fast, and the operation control is required to reduce the line speed; The deviation from the nozzle induction of the laser jet cutting machine to the laser focus area is large, so it is necessary to re detect the nozzle induction data, especially when cutting aluminum materials.
Laser cutting machine is a kind of equipment that can melt and evaporate the workpiece when the laser beam shines on the surface of the workpiece to achieve the purpose of cutting. In daily use, it is necessary to frequently inspect the working state of the voltage regulator to prevent the occurrence of faults. Maintenance skills of voltage stabilizer in laser cutting machine
For the inspection of the stabilized voltage power supply of the laser cutting machine, it is mainly to observe the compensation transformer to see whether the temperature rise of the voltage regulating transformer is normal, whether there is overheating, coil discoloration and other phenomena. Check whether the contact of the carbon brush is good, monitor whether the input and output voltages are normal, and whether there is overload.
In order to carry out more strict maintenance, dust and dirt on all parts of the voltage regulator shall be removed every three months, the chain drive system shall be checked for normal operation, the chain wheels shall be oiled, the tightness of the chain shall be adjusted, and the carbon brush holder shall be checked for inclination and jamming. If any, adjustment shall be made.
In addition, check whether the electrical contacts are damaged, and replace or repair them in time if any; Check whether the column voltage regulating transformer operates flexibly and whether the carbon brush is in good condition. Replace the damaged or heavily worn carbon brush in time. If there is burn or carbon brush powder on the coil contact surface, polish it with 0 # fine sand in time and remove the dust.
