When using CNC flame cutting machine, there are many factors affecting the gas flame cutting process, among which the cutting oxygen flow plays a vital role in gas flame cutting. Cutting the oxygen flow should not only burn the metal, but also blow the oxide generated by combustion out of the notch. Therefore, many parameters of cutting oxygen have an important impact on gas cutting quality and cutting speed. The following small series will mainly briefly analyze the impact of cutting oxygen pressure on cutting quality& nbsp;< br /> With the increase of cutting oxygen pressure, the oxygen flow increases accordingly, so the thickness of the plate that can be cut increases. However, when the pressure increases to a certain value, the cuttable thickness also reaches the maximum value. When the pressure increases, the cuttable thickness decreases. The effect of cutting oxygen pressure on cutting speed is roughly the same as that of cutting oxygen flow& nbsp;< br /> Generally, when gas cutting with ordinary cutting nozzle is used, under the condition of low pressure, the cutting speed increases with the increase of pressure, but when the pressure exceeds 0.3mp, the cutting speed decreases; If you continue to increase the pressure, not only the cutting speed will be reduced, the incision will be wider and the section of the incision will be rougher. When gas cutting with diffusion nozzle, if the cutting oxygen pressure meets the design pressure of the nozzle, when the pressure increases, the cutting speed will increase with the increase of the flow rate and momentum of cutting oxygen flow& nbsp;< br />
