The Characteristics of Plasma Cutting of CNC Cutting Machine

Cutting mechanism

While the plasma arc is formed in high temperature,the cooling gas around the arc column in the nozzle hole is heated by the arc column,turn to high temperature and high pressure gas,spray out from nozzle in high speed,so that the plasma arc flow at the mouth with a very high speed(Up to the speed of sound or supersonic),showing a strong impact.
Use high temperature to melt the workpiece to be cut,with the mechanical impact of flow forcibly excluded the molten metal to form a slit.

Cutting characteristics

Widly applications

Energy concentration, high temperature, can cut any high melting point of metal and non-metallic materials.

High cutting quality

As the plasma arc column smaller,large scouring force,so it is narrow incision,the edges are smooth and tidy.

Tiny deformation after cut

Due to the narrow incision, the heat affected zone is very small, so there will not appear crack the edge, hardened or large deformation and so on while gas cutting.
