These CNC plasma machines are widely used in diverse
They work in a similar pattern like that of laser machineries but these CNC machines provide the gain of lesser cost and maintenance requirement. The difference is in terms of various features, CNC machines come in different packages from solid, heavy-duty, fully welded single unit mounted on table or if smaller cuts need to be done then CNC machines can just remain bolted to the table while in some cases there is no cutting table as well. While using these CNC machine it's very crucial for the operator to wear eye goggles and other coverings for hands and body, because the high heat produced during cutting can cause significant damage to human body. CNC system allows to feed some programmed details to these machines, so that during that process they can cut consequently, while in some cases we need to achieve certain depth in cutting or doing it in different design need to be done which is possible due to this system. This machinery has certain advantages and disadvantages as well. Among advantage is their fast operation, with electrically operated they don't need to be preheated and just starts operation without delay. Its preciseness is excellent, possible with the help of programmed cutting software, torch head cuts plainly and efficiently and generally there is no need to use some secondary cutting techniques after CNC machines. Quality cutting and versatility in cutting is the distinctive feature of these cutting machines since they are able to cut very deeply and quality of cutting is un-matching as compared to other equivalent cutting techniques. They are safe to operate, because they are equipped with exhaust system to drain out any smoke produced. In disadvantages, first one is the cost, being lesser in cost compared to laser but since they are equipped with advance cutting technology and equipment their cost is very high. But with these overall cost of labor is reduced. Also, there is a problem with plasma cutting that we get harden metal corners due to heat. Besides these overall CNC machines are the most effective tool of metal cutting in industry today.
