Why do laser cutting machines have errors?

Once it is found that the cutting quality of the laser cutting machine is not up to standard, it is very likely that there is an error in the operation of the equipment, resulting in substandard cutting quality. Therefore, when it is found that there is an error in the cutting machine equipment, it must be adjusted in time to avoid greater loss. Then again, what are the reasons for the error of the equipment?

  1. Workpiece geometric error
    Due to various reasons, the surface of the object processed by the laser cutting machine is uneven, and during the cutting process, heat will be generated, so that the surface of the thin plate part is easily deformed, and due to the uneven surface, the laser focus and the surface of the object to be processed will also be generated. The position of the stochastic changes randomly from the ideal position.
  2. Errors generated by workpiece clamping device
    The workpiece to be processed is placed on the needle-shaped worktable. Due to the machining error and the wear between the workpiece and the workpiece for a long time, the needle bed will be uneven, and this unevenness will also produce random errors in the position between the thin steel plate and the laser focus.
  3. Programming errors
    In the process of laser cutting machine processing, the processing trajectory on the complex surface is fitted by straight lines, arcs, etc. There are errors between these fitting curves and the actual curve. These errors make the relative position of the actual focus and the surface of the processing object and the ideal programming position error. Some teaching programming systems also introduce some deviations.
    Therefore, the main reasons for the errors of the laser cutting machine are the above. When it is necessary to adjust the equipment errors of the cutting machine, you can start from the above aspects, so that you can quickly find the causes of the equipment errors and solve them.
