Plasma cutting is a procedure that cuts through electrically resistive materials such as stainless steel, aluminum, copper, brass and even other metallic substances by means of an electrical stream of high-energy plasma compressed in a gas. The plasma cutters work much like a gun, and the work pieces are placed between the nozzle tip and the work piece to be cut. Commonly, other conductive materials can also be cut in with a plasma cutter, including steel:

Plasma cutting can be used for precision fabrication of complex shapes such as bowls or bottles or other detailed shapes. It can also be used for precise surface finish details in:

  • furniture making
  • metalworking
  • electronics
  • aerospace
  • automotive
  • plumbing
  • architecture

A common use of plasma cutting machines is for detailed metal fabrication. This includes:

  • creating hollow parts such as the nose of a plane
  • flaps on wing surfaces
  • internal designs such as electrical connectors
  • electrical wiring

These parts are cut from a plastic or metallic base material via a laser or other type of light energy. The term “laser cutting” refers to this process because a laser cuts the metal by exposing it to a plasma arc, which is a highly intense beam of light created by an electric source.

Creating Special Catalyst:

Another application of plasma cutting involves creating a bead-like product from a mixture of molten metal and a special catalyst. In this process, a large sheet of metal is turned on its side, so that the metal and the catalyst melt onto the thin metal bead. This creates a bubble of gas under pressure, which is released when the metal bead is pushed down into a hole.

Gas lines used in plasma cutting machine CNC is typically copper or stainless steel. A small hole is drilled into the metal, and a torch is used to torch the wire mesh to expose the metal inside. A small electric torch is then used to heat up the metal, causing it to expand until the metal becomes hot enough to flow with the wire mesh.

Creating Clean and Precise Cuts:

A major advantage of plasma cutting and other high-speed plasma cutting processes is that they can create a very clean cut because all the moving parts are in line with each other. The plasma stream doesn’t hit the parts at different times, which results in a very consistent, hot plasma cut. Click link for more information
