  The flatness of the cutting edge is critical when producing material that is more than 18mm thin and thick. When leaving the focus, the laser emits and the cut will widen towards the top or bottom depending on the part of the focus. The cutting edges are spaced a few millimetres apart in a vertical orientation. The more vertical the edge, the higher the quality of the cut.


  Thermal influence of the cutting material


  As a machine and equipment used in the production and processing of thermal cutting, it is difficult to avoid thermal effects on the material during the entire application process. Its main manifestation consists of three levels: the heat-affected zone; dents and dips; and material deformation. The heat-affected zone is the area that is heated along the perimeter of the wound during the entire laser cutting process. At the same time, changes in the material's own structure can occur. For example, some materials can harden. The heat-affected zone is the area of transformation in which the internal structure is transformed by the high temperature.


  Pits and dips can have a bad effect on the appearance of the cutting edge and affect the appearance of the laser cutter. They can cause incorrect cutting that should normally be avoided; ultimately, if the part is heated up significantly, it will deform. This is crucial in careful production processing, as laser cutting manufacturers here are usually only a few tenths of a millimetre wide in total for lines and couplings. Manipulating the output power of the laser and using short laser monopulses can reduce the heating of the part and prevent deformation. The wire is placed into the crimping line and gradually from one end to avoid the wire suddenly popping out, the end is snapped up first and a section of the grommet is subsequently placed for a period of time, after which the grommet is tapped gently to facilitate the crimping edge being close to the wire.


  The above is about how to judge the quality of laser cutting processing of sheet metal parts in the sheet metal parts processing factory, thank you for reading the article.
