CNC Plasma Cutting Machine
Principles of Operation: At the heart of the CNC plasma cutting machine’s capability lies the fusion of heat and ionized gas. The principle is rooted in the phenomenon of plasma, a state of matter in which a gas becomes ionized due to the application of extreme heat or an electric field. In the context of plasma cutting, a high-velocity jet of ionized gas, known as plasma, is generated and directed toward the workpiece. The plasma arc conducts electricity from the torch to the workpiece, melting the material as it traverses.
The process starts with a pilot arc, a low-energy discharge that bridges the gap between the torch nozzle and the workpiece. This pilot arc ionizes the gas, forming the conductive plasma stream. Once the pilot arc establishes a conductive path, a higher-energy arc is initiated, resulting in the creation of an intensely hot plasma jet. The plasma’s temperature reaches levels that can melt through even the toughest metals, allowing the machine to cut with precision.
