subject: Cnc Plasma Cutting Machine : Transformation From Expensiveness To Affordability [print this page] The plasma cutting process assumed the commercial use in the first phase of sixties, But it was confined to the handful of people, because of being extremely expensive and exorbitant as well its process was complicated and onerous, carried out by applying burning services in order to cut metals and plates.
Since the advent of plasma cutting technology, around 70 years ago, it has remarkably advanced. If we go back to previous plasma cutting technology that was horribly slow and power consumption was greatly high owing to constriction of arc. Around 3 decades back, the concept of using tap water to produce secondary gas for performing cutting process came into existence. But it failed to offer high-precision cutting, without compromising on the speed. Subsequently, Plasma Technology, using nitrogen as primary gas and ordinary water as the shield gas, known as a nitrogen-water process, has been introduced. Plasma cutting machines divide the water from nitrogen gas in the torch that produces hydrogen and oxygen, which lowers down the atmospheric pressure in cutting zone and keeps it away from the contaminating elements, resulting in the clean and dross-free cut surface. In spite of that, plasma cutters were ponderous as well expensive, so disposed to carry out the same cutting patterns even in a bulk production.
As the technology advanced in 1990s, Computer Numerical Control or CNC Plasma Cutting Machine was phased in and brought about drastic transformation in metal cutting mechanism, This machine is really a versatile juggernaut, that is capable of rendering varied cutting shapes and patterns according to the applicational requirement.
The plasma cutting technology itself, efficient enough to provide almost surgical precision, but roughness and dimensional inaccuracy surface in cut pieces because of cutting torch that is handled by human hands. But after the introduction of CNC Plasma Cutting Machines , such drawbacks have been overcome. As CNC Machine uses the personal computer to create the shapes and control the cutting process, that produces smoother and dimensionally accurate shapes, encompassing even surface, intricate curves, fine corners and inside cuts.
