A CNC Plasma Cutter combines the special power of plasma with the
efficiency, accuracy and speed of CNC (Pc Numerically Controlled)
software program. Combine these two items with a really strong, fully welded
machine base, and you have got a formidable cutting machine.
Plasma exists only at pretty high temperatures and is
utilized by plasma cutting systems to cut electrically-conductive metals
really neatly and very quickly. A CNC Plasma Cutter adds specialized
software program that controls and directs the plasma cutting torch with speed,
accuracy, efficiency and repeatability.
Put simply, plasma is usually a
gas that has been compressed and energized towards the point that some of
the electrons break no cost from and travel with their nucleus. A nozzle
at the cutter's tip concentrates the gas and introduces a spark, and
turns the gas stream into plasma. Inert or semi-inert gases are utilised to
shield the region exactly where the plasma touches the metal. The force of the
plasma is powerful enough to blow the molten metal out of the work piece,
producing a thin (much less than a 1/16" wide), clean cut with small or no
slag. The plasma itself reaches temperatures as high as 30,000 degrees
Fahrenheit and simply cuts via 2" inches of metal.
The portion
of a CNC plasma cutting machine that makes it so extraordinary efficient is the
Computer Numerically Controlled (CNC) software. The CNC software program, with
the help of the laptop or computer, controls and directs the plasma cutting torch
with speed, accuracy and efficiency. Computer-based software programs
like CAD/CAM are an integral part of each CNC machine tool. The CNC
software also assures precise handling of the machine and exacting
distances among the plasma nozzle and metal sheet. CNC software program
ususlly includes nesting capabilities, producing the plasma cutter even
much more efficient.
Plasma cutters come in all shapes and sizes. What
makes the distinction between them, is their construction and their
components. Top quality units feature solid, heavy-duty, fully welded,
unitized construction. Much less highly-priced units use a much less stable, bolt
together construction or do not come having a table at all. A less stable
cutting table leads to much less accurate plasma cutting plus a less
effective machine.
A word of caution need to be mentioned about
any tool. Though an incredible effective cutting machine, a plasma
cutter can also do terrible damage towards the human body. Besides working
smart, an operator must wear goggles (shade #5), gloves and
protective clothing.
