A plasma jet is created by an electric arc by heating a stream of an inert gas to a very high temperature which is then forced through an orifice in a nozzle. This plasma jet can cut through metal by melting it and it also blows away the molten metal while cutting. This is the process by which a plasma torch cuts metal. A plasma torch can be used to cut metals of varied thicknesses and the plasma cutting method is very valuable to cut thick and thin cross-sections of metal.
CNC Plasma Cutters
CNC or computer numeric controlled plasma cutting systems are automatic and are very efficient when it comes to cutting metals. They can effortlessly cut varied metals such as stainless steel, titanium plate, iron sheet, carbon fibre, galvanized sheet, aluminium sheet, etc. Usually, a plasma cutting machine is accompanied by a robotic cutting table and offers various features.
A CNC machine has gears and various speed adjustments that enable the plasma cutter to move accurately in all directions. The rigid and lightweight parts of the CNC cutter ensure that the plasma cutter can cut with precision at several speeds. The height of the plasma cutter tip can be adjusted automatically without the requirement of human intervention.
The CNC cutting system is usually programmed by the manufacturer so that it performs optimally. These CNC cutting systems can be used even by small shops to produce specialty parts and even to create art pieces.
The CNC cutting tables equipped with plasma torches can produce precise and accurate cuts whose quality cannot be matched by hand-held plasma cutters. The superior CNC technology has rendered obsolete the skills required by humans to cut materials precisely and continuously without a stop and also follow repeating processes without any errors.
Advantages of CNC Plasma Cutting Systems
CNC plasma cutting systems are advantageous in many ways. These cutting systems reduce material wastage, cut down production costs and improve productivity. CNC plasma cutting machines can be programmed in order to generate the highest yield. The program can be used and reused over time without any variation or can be upgraded if required.
While the advantages of CNC plasma cutting cannot be understated and this method of cutting can be used for several cutting applications, big or small, strict safety measures must be enforced with regard to the operation of CNC plasma cutting systems to ensure that the people operating the plasma cutter are safe and secure.
