1. How to calculate the nitrogen flow when the laser cutting machine is working?
The following factors shall be considered in the calculation of nitrogen flow:
Material thickness: this will affect the pressure required by the nozzle and auxiliary cutting. Usually, with the increase of material thickness, the demand for flow will also increase (the higher the pressure, the larger the nozzle)
Material type: the amount of nitrogen consumed varies with different material types
Normal operation time: or laser on time, that is, the time when the laser is used. When the metal is replaced, the device will not consume N2.Downtime: We can also consider downtime
2. How to calculate the nitrogen purity when the laser cutting machine is working?
As long as 99.99% nitrogen purity is used, the surface treatment is usually as good as 99.999% purity. 99.99% is a common purity choice for laser cutting.
