A computer controlled plasma cutter is used to cut parts out of metal plate and is also used to cut through pipes and structural beams that are used for a wide range of purposes and applications. The plasma torch is controlled by what is called a computer numerical control or a CNC, meaning that the computer directs the machines movements via numerical codes within the program ensuring speed and precision.
How Does Plasma Cutting Work?
Plasma cutting is a process that works by using an accelerated jet stream of hot plasma to cut through metal plate. This accelerated jet stream is produced by creating an electrical arc between the plasma cutter and the work piece in order to create the channel of plasma. This is done using ionized gas that is pushed through and out of a nozzle and toward the workpiece at high speed.
What are the Main Uses for a CNC Plasma Cutter?
This cutting process is typically used to cut through conductive metals such as copper, steel, brass, aluminum. A plasma cutting machine is great for cutting parts into a variety of different profiles, shapes, curves, and angles. To achieve the production of a variety of parts, there are three common CNC cutting patterns that are generally used, including:
* 2D Plasma Cutting – most common type of plasma cutting and is used to produce flat silhouettes or profiles.
* 3D Plasma Cutting – adds a third dimension by use of a beveled edge or angular cut through the workpiece and is commonly used for flat profiles, but unlike 2D cutting, can cut at other angles aside from 90 degrees.
* Tube and Section Plasma Cutting – the workpiece, such as tubing, is fed through the machine for processing. Much like 3D cutting, this cutting process has a cutting head that can tilt and rotate.
Known for accuracy and speed, CNC plasma cutters are used in fabrication shops as well as in industrial construction due to its efficient cutting performance and low cost of operation compared to water-jet and laser machines. Plasma cut parts are also widely used as stock in the machining industry where further work is done to the part for the application.
