Tube laser cutting machine laser head debugging

Laser cutting machine can complete the processing of tubes, and laser cutting is obviously more accurate and efficient than traditional cutting. However, after the laser head of the laser cutting machine has been used for a long time, the accuracy of the machine will also have errors, and it needs to be debugged in time, otherwise it will affect the processing quality and efficiency. So today, let's talk about the laser head debugging of the tube laser cutting machine.

1. The cutting focus of the laser cutting machine is on the surface of the workpiece

This focusing mode is also called 0 focal length. This focusing mode generally needs to be determined according to the actual situation, the processing requirements of the upper and lower surfaces of the material. In general, the smoothness of the cutting surface depends on the distance between the cutting surface and the focus. The closer the cutting surface is to the focus, the smoother it is, and the lower surface that is relatively far away from the focus of the cutting machine appears to be rougher.

2. The cutting focus of the laser cutting machine is on the top of the workpiece

The cutting focus is on the top of the workpiece. At this time, we also call the focusing mode negative focal length. It is generally used to cut materials with high thickness. The reason why the cutting focus is positioned above the cutting material is mainly because thicker plates require a larger cutting width during the cutting process, otherwise the oxygen delivered by the nozzle is very likely to be insufficient, causing the cutting temperature to drop. The cutting effect of this method is relatively rough on the cutting surface and is not suitable for high-precision cutting.

3. The cutting focus of the laser cutting machine is inside the workpiece

This focusing mode is also called positive focal length. In this mode, since the focus is far away from the cutting surface of the cutting material, the cutting width is larger than the cutting point on the workpiece surface. At the same time, the required cutting airflow is large, the temperature is sufficient, and the cutting and perforation time is slightly longer; so the workpiece material is selected when it is a hard material such as stainless steel or aluminum.

The laser head debugging method of the pipe laser cutting machine is introduced here. Whether the accuracy of the laser cutting machine is accurate greatly affects the production quality. Therefore, we need to pay attention to it.
