The working principle of NC plasma cutting machine is compressed air as the working gas, with high temperature and high speed plasma arc as the heat source, the metal will be cut local melting and at the same time with high speed airflow will have melted metal blown away, forming a narrow slit.
The process is as follows:
Ionization:
→ Formation of independent electrons and ions
→ Changes in temperature and electronic properties compression arc thermal cutting process (plasma beam) Plasma beam:
→ High temperature (energy)
→ High kinetic energy (fast airflow speed) plasma beam to melt the material and blow off the slag.
Features:
Material thickness: 0.5mm to 150mm
Typical thickness: 3mm to 70mm
Conclusion:
Cutting quality low to high
→ Smooth, inclined cutting surface
→ From the metallic point of view, its oxidized surface is good
Medium heat input
→ Medium to high cutting speed
→ Harden in the heat-affected zone
→ For conductive materials only
