Three Focal Points Relations of Laser Cutting Machine
It's important for laser cutting equipment operators to know the rules of laser beam focusing.Do you know three focal points relations of laser cutting machine ?Now,let ’ s make a brief introduction for you. 1. Cutting focus on the workpiece In this way we also become a negative focal length, because the cutting point is not located on the surface of the cutting material nor is it located inside the cutting material, but is located above the cutting material. This method is mainly used with cutting materials with high thickness. The reason why the focus of this approach is on the cutting material is mainly due to the need for thicker cuts of the thick plate, otherwise the oxygen delivered by the nozzle is extremely prone to cause insufficient and the cutting temperature is reduced. However, one of the disadvantages of this approach is that the cutting surface is rough and not very practical for high-precision cutting. 2 . C utting focus inside the workpiece This me...
