The relationship between the cutting focus and metal material

This article is about The relationship between the cutting focus and metal material.Many customers asked me about the questions.Hope it can help you learn more about the question.

The following are three different situations of laser cutting machine.

1.Cutting focus on the surface of workpiece.

It is also called 0 focal length. In this mode, the smoothness of the top and bottom surfaces of the workpiece is usually different. Generally, the cutting surface close to the focus is relatively smooth, while the lower surface away from the cutting focus appears rough. This mode should be based on the process requirements in the actual application.-laser cutting machine

2. Cutting focus on the workpiece.

It is also called negative focal length. The cutting point is positioned above the cutting material. This method is mainly suitable for cutting materials with high thickness. But the disadvantage of this method is that the cutting surface is rough and not practical for high precision cutting.

3. Cutting focus inside the workpiece.

It is also can call positive focal length. Since the focus is inside the material, the cutting airflow is large, the temperature is high, and the cutting time is slightly longer. When the workpiece you need to cut is stainless steel or aluminum steel, it is suitable to adopt this mode.
When using fiber laser cutting machine, operators can adjust flexibly according to actual needs.
