We all know that the laser cutting machine is very accurate in cutting materials, but sometimes there will be some mistakes, which will affect our cutting effect, and even may cause losses. Therefore, we need to find out the reasons as soon as possible and make timely adjustments. Then, there are many reasons for the error of the laser cutting machine:
1. Geometric error of workpiece.
Due to various reasons, the surface of the processing object of the optical fiber laser cutting machine fluctuates and generates heat during the cutting process. In this way, the surface of the thin plate is easy to deform, and due to the unevenness of the surface, laser focusing and the processed object will also be generated. The position of the surface varies randomly from the ideal position. Roughness of paper cutting. Generally, the smoother the surface of the cutting material, the better the cutting quality.
The thickness of the cutting material exceeds the standard. Generally, the thickness of sheets that can be cut by metal laser cutting machine is less than 12. The thinner the sheet, the easier it is to cut and the better the quality. If the plate is too thick, the laser cutter will be more difficult to cut. Under the condition of ensuring cutting, there will be errors in processing accuracy, so the thickness of the plate must be determined.
2. Error caused by workpiece clamping device.
The workpiece to be processed is placed on the workbench. Because of the machining error and the long-term wear between the workpieces, the cutting machine will appear uneven, and this uneven will also produce random errors in the position between the thin steel plate and the laser focus.
Why does the laser cutter cut the wrong material?
3. Programming error.
In the process of optical fiber laser cutting machine, the processing path on the complex curved surface is fitted by straight lines, arcs, etc. There are errors between these fitted curves and the actual curves, which makes the relative position and ideal position of the actual focus possible. And the surface of the machined object. An error occurred in the programming location. Some teaching programming systems will also introduce some deviations.
4. The laser output power does not meet the standard.
When the laser cutting machine is running and debugging, it is necessary to ensure that the laser output power reaches the standard. Generally, the higher the laser output power is, the better the cutting quality is on the same thickness of the plate.
5. The focus position is incorrect.
If the focus of the laser cutting machine is not aligned, the cutting accuracy will be directly affected. Therefore, calibration and inspection must be carried out before operation. You can also purchase Jinan Jinwei auto focusing laser head when purchasing the machine to perform auto focusing to ensure cutting accuracy.
6. Processing speed. The cutting speed of laser cutting machine directly affects the machining accuracy. Therefore, it is necessary to achieve the best match between cutting speed and material before operation.
When working on the laser cutting machine, we must take it seriously. Under normal circumstances, due to these random errors, it is difficult to avoid geometric errors of the workpiece, errors caused by the workpiece clamping device and errors caused by programming. We will try our best to reduce errors, so as to improve the accuracy of the cutting machine.
