When using CNC flame cutting machine, there are many factors that affect the gas flame cutting process, among which cutting oxygen flow plays a crucial role in gas flame cutting. Cutting open the oxygen flow not only burns the metal, but also blows away the oxide generated by burning from the cutting. Therefore, various parameters of oxygen cutting have a significant impact on the quality and cutting speed of gas cutting. Below, the editor will briefly analyze the impact of oxygen pressure on incision quality.

As the cutting oxygen pressure increases, the oxygen flow rate increases accordingly, resulting in an increase in the thickness of the plate that can be cut. But when the pressure is added to the relative value, the thickness that can be cut also reaches a large value. Increasing the pressure further reduces the thickness that can be cut. The effect of cutting oxygen pressure on cutting speed is roughly the same as the principle of cutting oxygen flow rate.

In general, when using a regular cutting nozzle for gas cutting, the cutting speed increases with the increase of pressure at lower pressures. However, when the pressure exceeds 0.3MP, the cutting speed actually decreases; Continuously increasing the pressure will not only reduce the cutting speed, but also widen the cutting area and make the cutting section rougher. When using a dispersed cutting nozzle for gas cutting, if the cutting oxygen pressure matches the design pressure of the cutting nozzle, as the pressure increases, the cutting speed will also increase with the increase of the flow rate and momentum of the cutting oxygen flow.
