What is cnc plasma cutter ?

A CNC plasma cutter is a machine that is specifically designed to cut through electrically conductive materials by using a computer to control and direct an accelerated jet of hot plasma at the material being cut. CNC plasma cutters can cut through a wide range of different materials, including steel, aluminum, brass, and copper, and can be used for a selection of different industries like fabrication and welding shops, auto repair and restoration shops, industrial construction sites, and salvage operation sites.

CNC plasma cutter how it works?

The plasma cutting process is a thermal cutting method. Which means that is uses heat to melt the metal instead of mechanically cutting it.

The overall mechanics of the system is always the same. Plasma cutters use compressed air or other gases, such as nitrogen. Ionisation of these gases takes place to create plasma.

Typically, the compressed gases come into contact with the electrode and then ionise to create more pressure. When the pressure builds up, a stream of plasma is pushed towards the cutting head.

The cutting tip constricts the flow to create a stream of plasma. This is then subjected onto the workpiece. As plasma is electrically conductive, the workpiece is connected to the ground through the cutting table.

As the plasma arc contacts the metal, its high temperature melts it. At the same time, the high speed gases blow away the molten metal.

Starting the Cutting Process

Not all systems work the same way. Firstly, there is a generally lower-budget version called high frequency contact. This is not available for CNC plasma cutters because the high frequency can interfere with modern equipment and cause problems.

This method uses a high voltage and high frequency spark. The creation of the spark takes place when the plasma torch touches the metal. This closes the circuit and creates the spark which, in turn, creates plasma.

Plasma cutting metal

Another option is the pilot arc method. First, the spark is created inside the torch by a high voltage and low current circuit. The spark creates the pilot arc which is a small amount of plasma.

The cutting arc gets created when the pilot arc is brought into contact with the workpiece. The operator can now start the cutting process.

A third way is using a spring loaded plasma torch head. Pressing the torch against the work piece creates a short circuit which makes the current start to flow.

Releasing the pressure establishes the pilot arc. The following is the same as in the previous method. That is bringing the arc into contact with the work piece.
