Plasma cutters are essentially used to cut various metals such as stainless steel into different lengths and shapes and the process is key for several modern industries ranging from construction to manufacturing. Plasma cutting has risen as the main solution for cutting and shaping various metals like stainless steel into many forms such as beams that are used in infrastructure and construction.
Plasma Cutting over the Years
The use of plasma cutting began in the 60s when welders realised the benefits and ease of cutting molten metal rather than cutting hard metal using another metal object that creates surfaces and edges that are not very precise and are more susceptible to faults.
In the following decades, CNC (computer numerical control) plasma cutting systems started entering the industry in the 80s and 90s. A CNC plasma cutting system heats up the metal workpiece until it becomes soft and turns into a molten state and then makes use of highly precise cutting tools that are computer controlled to cut the metal without issues such as chipping, running, etc.
Let us take a look at the ways modern plasma cutting machines have evolved:
Increased Cutting Precision
Plasma cutting manufacturers are constantly trying to increase the precision of the AC servo motors or amplifiers, gearboxes and other components that power the modern plasma cutters and when comparing the price of the plasma cutting system vis-à-vis the quality, the ability of the machine to cut in minute and precise motions is the main feature that must be considered. Even the most efficient and durable plasma cutting machine is useless without precision, which is required for most construction and manufacturing applications.
Stronger and More Reliable Components
Modern plasma cutting systems are designed in a way that they can be used continuously for several hours at a stretch and for several years. For this, plasma cutting systems manufacturers endeavour to equip their machines with strong amplifiers and motors, which are essentially the key components behind any plasma cutting system’s cutting and heating capabilities.
Today, the manufacturers of plasma cutting systems are expanding their offerings continuously to include more powerful and larger size configurations in order to accommodate the ever-expanding industry requirements in the 21st century. Plasma cutting systems are available in varied lengths and allow metal workers to tackle almost any type of cutting job possible by making use of a single machine. And, in addition, CNC control is making it much easier for fabricators to produce highly-precise cuts with the aid of intelligent machine guidance. Plasma cutting has come a long way over the years and as technology advances, is only set to grow.
