When using a CNC flame cutting machine, there are many factors that affect the gas flame cutting process, in which the cutting oxygen flow plays a crucial role in gas flame cutting. The cutting of the oxygen stream requires both the burning of the metal and the burning of oxides from the incision. Therefore, the various parameters of cutting oxygen have important influences on the cutting quality and cutting speed. The following Xiaobian will mainly analyze the effect of cutting oxygen pressure on cutting quality.
As the cutting oxygen pressure increases, the oxygen flow increases accordingly, so the thickness of the plate that can be cut increases. However, when the pressure is increased to a certain value, the cuttable thickness reaches a maximum value, and then the pressure is increased, and the thickness that can be cut is reduced. The effect of the cutting oxygen pressure on the cutting speed is approximately the same as the principle of cutting the oxygen flow.
Under normal circumstances, when cutting with an ordinary cutting nozzle, the cutting speed increases as the pressure increases under low pressure. However, when the pressure exceeds 0.3 MP, the cutting speed decreases, and the pressure continues to increase, not only cutting As the speed decreases, the incision widens and the incision section becomes rougher. When cutting with a divergent nozzle, if the cutting oxygen pressure matches the design pressure of the cutting nozzle, the cutting speed will increase as the flow rate and momentum of the cutting oxygen flow increase as the pressure increases.
In addition to the several factors mentioned above, there are many factors affecting the final cutting quality during the gas flame cutting process, such as the power of the preheating flame, the composition, performance, surface state, and initial temperature of the metal being cut. Only comprehensive consideration of various factors can make the cutting effect more perfect!
