Since World War II, plasma cutters have been used for cutting metals for the mass production of aircrafts, weapons and armours. This method was used since metals such as steel, copper and aluminium could not be cut using flame. Since then, the use of plasma cutters has proliferated into various industries which require precision metal cutting and manipulation.
What is Plasma Cutting?
Plasma cutting as we know is the technique of cutting metals of varied thickness using a plasma torch or gun. When inert gas or air is passed through an electric arc, a directed plasma flow is generated, which is formed due to the ionization of the gas or air. The plasma has conductive properties like metal. When the plasma is forced through a nozzle at a very high speed and temperature, it can cut through metal very easily and the molten metal is also blown away from the cut, leaving behind very precise and clean lines.
CNC Cutting Tables
CNC plasma cutting tables, also known as Computer Controlled Numerical tables are computer controlled plasma cutting tables which help to achieve sharper, cleaner and more accurate cuts. CNC plasma tables are very useful for multi-axis cutting of thick material and are widely used in the heating, ventilating and air conditioning (HVAC) industry. The use of the CNC plasma tables increases efficiency and productivity. We can also see the prevalent use of these CNC tables in agriculture, construction and educational institutions.
The CNC cutting table helps to produce accurate and defined metal shapes from heavy plate metal or sheet metal. The CAD design software that accompanies the CNC plasma table prepares the designs to be cut automatically. The software is generally easy to use and does not require intensive training. The software not only creates the designs for cutting, but also runs the machine and ensures cut height and alignment of the pointer. The CNC plasma cutting tables are easy to use, versatile and are economically viable.
CNC plasma tables have indeed revolutionized how cutting is done today. There have been many new developments in the cutting arena. The use of smaller nozzles and finer plasma arcs allow laser-like precision that give fabricators the luxury of producing parts that need little or no finishing. From small hobby shops to large scale industrial applications, more and more businesses are turning to the use of CNC plasma cutting tables.
