How To Judge The Quality Of The Laser Cutting Machine

When using a laser cutting machine to process metal, the cutting effect of the laser cutting machine is often encountered, and the cutting quality is not in place. It not only wastes the materials, but also consumes the easy parts of the laser cutting machine itself. How to judge the quality of cutting? What kind of effect is the qualified cutting effect? ​​The following Qingyuan laser cutting machine manufacturers will take you to understand the optical fiber laser cutting machine and evaluate the quality of its processing.
1.laser cutting machines are used to cut workpieces with smooth surfaces, small lines, and non -brittle faults.
When laser -cut metal plates, the traces of the melting material will not appear in the incision below the vertical laser beam, but spray it behind the laser beam. As a result, curved lines were formed on the cutting blade, and these lines followed the moving laser beam tightly. To correct this problem, the use of low feed at the end of the cutting process can largely eliminate the formation of lines to a large extent.
2.The width of the cutting gap
Usually when we use a laser cutting machine, there will occasionally a large cutting gap, which will cause the cutting accuracy of the workpiece to decline and meet the production requirements. What should I do if I encounter such a problem?
◆Check whether there is a problem with the focal length. Pay special attention to cleaning the lens, replace the focal length of the new lens, and adjust the correct focal length value.
◆Check whether the lens is damaged or dirty, because this will cause laser scattering, which will cause laser beam to become larger. Replacement or cleaning lens is the only way.
◆Laser is also a factor that cannot be ignored. Check the quality of laser spots.
◆The air pressure during oxygen cutting is too large, which will cause too much cutting surface to burn and increase the cutting seam.

3.The verticality of the seam and the heat influence area
4.Do not burn the ingredients, do not form a melting layer, and do not form a slag
5. Rough plating on the surface of the cutting, the size of the surface roughness is the key to measure the quality of the laser cutting surface
For metal laser cutting machines, the texture and roughness of the cut section are directly related. The section pattern with poor cutting performance often leads to higher roughness. However, considering the differences in the causes of these two different effects, we generally separate them to analyze when analyzing the processing quality of metal laser CNC cutting machines. The laser cutting part will form a vertical line. The depth of the line determines the roughness of the cutting surface. The lighter the line, the smoother the cutting part. Roughness not only affects the appearance of the edge, but also affects friction characteristics. In most cases, the roughness should be reduced as much as possible. Therefore, the lighter the texture, the higher the cutting quality. It will inevitably cause armal impact on metal materials during use. Its expression form mainly includes three aspects.
◆Thermal influence area.
◆Point erosion and corrosion.
◆Material deformation.
In addition to the above principles, the state and final shape of the melting layer during the processing process directly affect the above processing quality evaluation indicators. Laser cutting surface roughness mainly depends on the following three aspects:
◆The internal parameters of the cutting system, such as light spots mode, focal length, etc.
◆The process parameters in the cutting process can be adjusted, such as power, cutting speed, type of auxiliary gas and pressure.
◆The physical parameters of processing materials, such as laser absorption rate, melting point, melting metal oxide viscosity coefficient, surface tension of metal oxides, etc. In addition, the thickness of the workpiece also has a great impact on the surface quality of laser cutting. Relatively speaking, the smaller the thickness of the metal workpiece, the higher the rough level of the cutting surface.
Why do most metal processing customers choose optical fiber laser cutting machines because it has certain advantages as a representative of advanced productivity.
◆Suitable for various metal plate processing, which has certain advantages in processing of metal plates below 20mm.
◆Any complex graphics can be processed, as long as you draw the input to the control system on the computer.
◆Excact -cut cutting, small thermal deformation, non -contact processing, and basically no second polishing treatment.
◆The cost of use is low. In the later use, only the basic electricity costs and the cost of the auxiliary gas are required.
◆Environmental protection and noise have no effect on the surrounding environment.
