In the process of industrial production and processing, NC flame cutting machine can cut various shapes of parts, with strong versatility. Generally, it is responsible for cutting sheet metal structural parts, and the cutting quality of structural parts directly affects the welding quality of the workpiece and the performance of the whole machine. The application of NC cutting machine in cutting links not only fully embodies the advantages of cutting automation and centralized cutting, but also greatly improves the utilization rate of sheet metal and the cutting quality and production efficiency.
Although the application range of NC flame cutting machine is much smaller than that of NC plasma cutting machine, but the redundant plate cutting, flame cutting has better cutting quality and lower processing cost. According to the general flame cutting parameters, the thickness of the carbon plate within 6-200 mm, ordinary carbon plate can be completed with the general flame cutting nozzle, but here it is suggested that enterprises should choose the appropriate cutting nozzle type according to the thickness of the material to achieve the best cutting effect.
The use of NC flame cutting machine, in addition to cutting gas, cutting thickness and cutting speed control, in addition to the matching of accessories should also have a choice, especially for different thickness of cutting materials, the choice of its cutting nozzle is particularly important.
In choosing the cutting nozzle type, the material within 50mm thickness is generally 1-4 cutting nozzle, 50-100mm is recommended to choose 4-5 cutting nozzle, more than 100 mm thickness material is 6-7 cutting nozzle. The reason is that different cutting speed, cutting gas pressure and different cutting nozzle type are suitable for different thickness of sheet metal. Because the thickness of 6-20mm sheet metal is changeable by heating, it can not cut through the edge of the sheet metal when cutting parts. The method of piercing is that the edge of the sheet metal is closed, and the cutting seam of the edge of the sheet metal is different from that of the sheet metal. The edge of the steel plate has a certain distance, which limits the dimensional deviation of parts caused by denaturation.
