A CNC plasma cutter features a few key components, including the table, plasma torch, and CNC software. The table, also known as the bed, is the cutting surface on which the workpiece sits. Above the table, a gantry will hold the plasma torch and move it around. This is the cutting unit, controlled by the computer software.
An electric arc is sent through a gas as it passes through a constricted opening. This increases the temperature of the gas up to 22,000℃ until it converts into plasma and conducts electricity. Then it flows from the torch to the workpiece, melting through the metal. The high-velocity plasma and compressed gas blow the hot melted metal away, cutting straight through and removing the excess.
Advantages Of Plasma Cutting
CNC plasma cutting machines provide several advantages, including precision, affordability, transportability, and more.
Clean And Accurate Cuts: Plasma cutters use air filters to remove any contaminants, ensuring every cut is clean and precise. This ensures a high level of precision, for a faster and smoother cutting experience.
Cost-Effective: CNC plasma cutters are relatively affordable, with our CNC Plasma Table packages starting from $19,900. The initial investment cost is also lower for thicker materials, making it a more accessible option for small to medium-sized businesses. Use our online price configurator to get more accurate pricing.
Portable: Plasma is a more portable option, with no need for gas bottles. This makes it easy to relocate your plasma cutter with little to no transportation concerns.
Can Cut A Wide Range Of Metals: Plasma cutters can cut many materials, including mild steel, stainless steel, steel alloys, aluminium, carbon steel, copper, and brass. The appropriate thickness is determined by the plasma and the CNC table so ask our experts to find the best option for your workshop.
Efficiency: CNC plasma cutters are quick and easy to use, significantly increasing your productivity and efficiency. The software used to control your plasma cutter automates everything, which dramatically speeds up production.
Disadvantages Of CNC Plasma Cutting
While the team here at Surefire CNC loves plasma cutting, we recognise there are some potential drawbacks. In particular, a cheap CNC machine of poor quality can be prone to inefficiencies with the equipment and software. To avoid this, we recommend opting for a reputable model like the XT Series Plasma Tables.
Additionally, the cut precision on a CNC plasma cutter may be marginally lower than on a waterjet cutter or laser cutting machine. However, these machines are more expensive to purchase and operate.
In summary, plasma cutters offer the perfect combination of accuracy, affordability, and ease of use for most industrial applications.
