When the thickness of the production processing material exceeds 18mm, the flatness of the cutting edge is very critical. As the beam moves away from the focal point, the laser diverges, and the kerf widens toward either the top or the bottom depending on the position relative to the focal plane. The cutting edge spacing is a few millimeters in vertical orientation. The steeper the edge, the higher the cutting quality.

Thermal effects of cutting materials

As the use of machinery and equipment for thermal cutting production and processing, it is difficult to avoid thermal effects on materials during the entire application process. Its main performance mainly includes three levels: heat affected zone; Dent and erosion; Material deformation. Among them, the heat-affected zone refers to the area that is heated along the periphery of the wound during the whole process of laser cutting. Meanwhile, the material’s microstructure also undergoes changes. For example, some materials become harder. The heat-affected zone refers to the region where microstructural transformations occur due to elevated temperatures.

Pits and erosion will adversely affect the appearance of the cutting edge and affect the appearance of the laser cutting machine. They will have incorrect cutting that should normally be avoided; eventually, if the part is heated significantly, it will deform. This is essential in meticulous production and processing, where laser cutting manufacturers usually have an overall width of only a few tenths of a millimeter because of the lines and couplings. Manipulating the laser output power and applying a short laser single pulse can reduce part burning and prevent deformation. Put the wire into the pressure wire, and gradually from one end to avoid the wire suddenly popped out, first buckle up one end, then place a buckle for a period of time, after the buckle is carried out, gently knock, so as to facilitate the winding edge close to the iron wire.

these are the ways to judge the laser cutting quality of sheet metal parts in sheet metal parts processing manufacturers. thank you for reading the article.
