Imported CNC plasma cutting machine has good cutting effect, which is very important because of this technical indicator.
With the wide application of CNC plasma cutting machines, we are increasingly concerned about the quality of plasma cutting and how to improve the cutting process!
The swirl ring is not configured for all plasma cutting machines. There are few domestic machines. The function of the swirl ring is mainly to generate eddy currents from the high-pressure gas inside the air compressor. It is like a rotating drill bit, so that the plasma The arc has a better penetration and produces a better cutting end face, which improves the grade of the plasma cutting machine.
Then constrain the plasma arc cutting. According to the confinement method of plasma arc, it is mainly divided into water recompression plasma arc cutting, magnetic field reconstrained plasma arc cutting and so on. As the plasma arc is compressed again, its current density and cutting arc energy are further concentrated, thereby improving the cutting speed and processing quality.
Fine plasma arc cutting. Plasma arc current density is very high, usually several times that of ordinary plasma arc current density. Due to the introduction of technologies such as rotating magnetic fields, the stability of its arc is also improved, so its cutting accuracy is quite high. Foreign fine plasma cutting surface quality has reached the lower limit of laser cutting, and its cost is only one third of laser cutting.
Ordinary CNC cutting machine. According to the main working gas used, it is mainly divided into argon plasma arc cutting and oxygen plasma arc cutting. Oxygen plasma arc cutting and air plasma arc cutting and other types. Cutting current is generally less than 100 A, cutting thickness is less than 30 mm.
