The so-called heat-affected zone means that the cnc flame cutter is heated along the area near the laser cut during the machining process, resulting in a certain change in the structure of the metal, which causes the metal to harden. The presence of heat-affected areas is detrimental to cnc flame cutters in laser cutting, especially for sheet metal parts and the smoothness of the edges. In addition to causing hardening of the metal, the heat-affected zone may cause dents and corrosion on the edge of the metal, which may cause errors in the actual processing. For the cnc flame cutter, especially in the precision machining process, subtle changes will lead to errors in the accuracy of the sheet metal parts, which directly affects the processing quality. The cnc flame cutter's surface roughness in laser cutting depends mainly on three aspects.
1.Cnc flame cutter is an inherent parameter of the cutting system, such as spot mode, focal length, etc.
2.Cnc flame cutter process parameters that can be adjusted during the cutting process, such as power size, cutting speed, auxiliary gas type and pressure.
The physical properties of the processed material of the 3cnc flame cutter, such as the absorption rate of the laser, the melting point, the viscosity coefficient of the molten metal oxide, and the surface tension of the metal oxide.
In addition, the cnc flame cutter has a great influence on the thickness of the machined part on the quality of the laser cut surface. Relatively speaking, the smaller the thickness of the metal workpiece, the higher the roughness level of the cutting surface, so choosing a suitable cnc flame cutter has a positive effect on improving production efficiency.
