The application of metal laser cutting machine is more and more popular. When we use this machine to process different workpieces, we should use different focusing methods to obtain the best cutting effect. Today, Chuyu Optoelectronics will introduce you to the three focusing modes of the metal laser cutting machine.
1. The cutting focus is above the workpiece
This is also called negative focus, because the cutting point is neither on the surface of the cutting material nor inside the cutting material, but above the cutting material. This focusing mode is mainly applicable to cutting materials with high thickness. However, the disadvantage of this mode is that the cutting surface is relatively rough and not very practical for high-precision cutting.
2. The cutting focus is inside the workpiece
This is also called focal length, and is usually used when you cut stainless steel or aluminum steel workpieces. However, the disadvantage of this focusing mode is that it requires larger airflow, sufficient temperature and longer puncture time. Therefore, this focus mode can be selected when you are working with high hardness materials, such as stainless steel or aluminum workpieces.
3. The cutting focus is on the workpiece surface
This method, also known as zero focal length, is usually used for SPC, SPH, SS41 and other workpieces. When using this mode, the focus of the cutter is on the workpiece surface. In this mode, the smoothness of the upper and lower surfaces of the workpiece is different. Therefore, this mode should be used according to the process requirements.
To sum up, different focusing methods should be used on metal laser cutting machine to process different workpieces, so as to give full play to its advantages. Please feel free to contact us for more useful knowledge about our machines.
