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 metal sheet and pipe cutters, especially in the precision machining process, subtle changes will lead to errors in the accuracy of the sheet metal parts, directly affecting the processing quality.The presence of heat-affected areas is disadvantageous for metal sheet and pipe cutters, especially for sheet metal parts and the smoothness of the edges. The three factors of metal sheet and pipe cutter accuracy are affected.
1. The inherent parameters of the cutting system of metal sheet and pipe cutter, such as spot pattern, focal length, etc.;
2. metal sheet and pipe cutter process parameters that can be adjusted during the cutting process, such as power size, cutting speed, auxiliary gas type and pressure;
3. metal sheet and pipe cutter in the physical properties of the processing materials, such as the absorption rate of the laser, the melting point, the viscosity coefficient of the molten metal oxide, the surface tension of the metal oxide.
In addition, the thickness of the workpiece also has a large effect on the surface quality of the metal sheet and pipe cutter. Relatively speaking, the smaller the thickness of the metal workpiece, the higher the surface roughness level of the metal sheet and pipe cutter. Therefore, choosing a suitable metal sheet and pipe cutter has a positive effect on improving production efficiency.
