Plasma Cutting System

Coatec India offers under a single roof all four super specialized segments of CNC Profile Cutting Technologies, viz., Laser, Plasma, Water Jet and Oxy Fuel. These are manufactured at a modern, well equipped with state-of-the-art facility to deliver top class quality, using world standard components from Germany and USA to deliver a quality and reliable product. Plasma Cutting is a process that is used to cut steel and other metals using a plasma torch. In this process, an inert gas (in some cases, 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 is an effective means of cutting thin and thick materials alike. Computer-controlled torches can pierce and cut steel up to 40 mm thick. 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 the past decade plasma torch manufacturers have engineered new models with a smaller nozzle and a thinner plasma arc. This allows near-laser quality on plasma cut edges. Several manufacturers have combined precision CNC control with these torches to allow fabricators to produce parts that require little or no finishing. The company offers ten models of plasma cutting. The CNC system remains the same in all of these models. The variation is in the plasma source, which starts from CutMaster (four models), AutoCut (three models) and Ultra cut (three models). Further, water mist shielding is offered for cleaner and corrosion free cuts.
