Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut. Plasma can also be used for plasma arc welding and other applications.
Plasma cutter has also been used in CNC
(computer numerically controlled) machinery. Manufacturers build CNC
cutting tables, some with the cutter built in to the table. The idea
behind CNC tables is to allow a computer to control the torch head
making clean sharp cuts. Modern CNC plasma equipment is capable of
multi-axis cutting of thick material, allowing opportunities for
complex welding seams on CNC welding equipment that is not possible
otherwise. For thinner material cutting, plasma cutting is being
progressively replaced by laser cutting, due mainly to the laser cutter's superior hole-cutting abilities.
A specialized use of CNC Plasma cutters has been in the HVAC industry. Software will process information on ductwork
and create flat patterns to be cut on the cutting table by the plasma
torch. This technology has enormously increased productivity within the
industry since its introduction in the early 1980s.
In recent years there has been even more development in the area of
CNC Plasma Cutting Machinery. Traditionally the machines' cutting
tables was horizontal but now due to further research and development
Vertical CNC Plasma Cutting Machine are available. This advancement
provides a machine with a small footprint, increased flexibility,
optimum safety, faster operation, energy efficiency, ergonomic and more
environmentally friendly.
