Plasma and Oxy Fuel Machines
Plasma Cutting: When a gas is heated to an extremely high temperature it ionizes. At this point the electrically conductive ionized gas can be called plasma.
When a high-velocity jet of plasma is delivered to a metal work piece an electrical arc is delivered with it. The heat of the arc melts the metal to be cut and the stream of ionized gas blows the molten metal away.
Plasma cutting can yield a variety of cutting speeds and quality depending on the material to be cut, the material thickness, the quality of the cut desired, and the cutting speed required. The ability to dial in the machine's amperage from 30 to 260 allows for this flexibility. High definition systems produce a much better cut with higher accuracy.
A simple rule of thumb: The more power you throw at it, the faster you will plasma-cut the metal. Cutting speeds are less affected by material thickness than other processes. In fact plasma cutting is effective for aluminum, particularly thick aluminum.
Because plasma cutting is not as precise as other metal cutting technologies it may not be able to deliver a series of functional holes. The wider kerf width affects part definition. That's why the technology is often paired with punching tooling. However, high-density plasma cutting can yield tolerances of ±0.010 in. to ±0.015 in. in closely monitored processes.
Automated material handling is available for plasma cutting machines as well as multiple heads.
Oxyfuel Cutting. In this method of metal cutting, a torch is used to heat metal to kindling temperature. The stream of oxygen that is trained on the metal reacts with the metal in a chemical process, oxidizing the metal and blowing it away to form the cut.
Oxyfuel cutting is primarily used for cutting mild steel in thicknesses from 3/8 in. to 12 in. The technology is not considered practical for aluminum or stainless steel, but can be used for titanium.Oxyfuel cutting has a very large heat-affected zone when compared to the other metal cutting technologies and is not as accurate, typically ± 0.0625 to ±0.125 in., although careful process control can result in much tighter tolerance parameters.
The technology has improved greatly in recent years with technical advancements. High-speed torches have resulted in cutting speeds that are 20 percent faster the previous generations'. Height-sensing probes and CNC gas regulation keep oxyfuel cutting operations running efficiently.
Automation technology can be added to allow for unattended, multitorch operation.
