CNC flame cutting machine is a common cutting equipment that is currently required for cutting and cutting in the market. Although the cutting range is smaller than plasma cutting, the cutting range is much smaller than plasma cutting. At present, the cutting thickness of numerical control flame cutting machine is between 6-200mm, and the cutting thickness of numerical control plasma cutting machine depends on the plasma power source, and is far inferior to the flame cutting machine. Today, our focus is not on the difference between the two, but on the importance of cutting nozzle selection for CNC flame cutting machines.
We all know that in the CNC cutting machine, the correct use of the cutting nozzle directly relates to the quality and efficiency of the flame cutting, and also relates to the life of the CNC flame cutting machine. Therefore, when cutting the steel plate, we must choose according to the material and thickness of the plate to be cut. Because, different cutting nozzles under different gases, the cutting thickness is also different.
Under normal circumstances: 0-4 # cutting nozzle maximum cutting thickness of 50mm or less; if you want to cut 50-100mm plate, we usually choose the 5 # or 6 # cutting nozzle; if the cutting thickness is more than 100mm, we will To choose a higher 7# or 8# cutting tip. Plates of different thicknesses should adopt different cutting speeds, cutting gas pressures and different cutting nozzle types. The specific nozzle performance parameters are shown in the following figure:
In the process of industrial production and processing, CNC flame cutting machine can cut all kinds of parts and has strong versatility. Generally, it is responsible for the cutting of the sheet structure, and the cutting quality of the structure directly affects the welding quality of the workpiece and the overall performance of the product. Therefore, we must choose the cutting tip according to the material and thickness of the plate to be cut before cutting the plate.
