Oxy-Fuel CNC machines use CNC technology to guide an oxyfuel torch. Oxy-fuel cutting involves heating the metal up to its ignition temperature and then, shooting a jet of oxygen at the metal to cut it.
The oxygen reacts with iron at high temperatures, and the high-speed flow of gas removes the iron oxide layer, cutting the metal and washing away the rust. This type of CNC can cut metals as thick as 6-20 inches. However, oxy-fuel cutting only works with ferrous metals.
However, it’s less accurate than other CNCs, because oxy-fuel cutting leaves a wide kerf with some kerf inconsistencies..
Oxy-fuel CNC tables cut parts that are then used in more precise machining processes. For example, a CNC grinder or a CNC lathe can be used to finish the surface of an oxy-fuel cut part with high accuracy.
