What is plasma cutting?
Plasma cutting has its roots in plasma welding in the 1960s and became a very effective way of cutting sheet metal and sheet metal in the 1980s. It has advantages over the “metal to metal” cutting method. ” tradition is to produce no metal shavings, for precise cuts and a cleaner advantage over cutting oxygen fuel. Early plasma cutters were large, slow, and expensive, and therefore tended to be specialized for repeating cutting patterns in “mass production” mode.
As with other machine tools, CNC (Computer Numerical Control) technology was applied to plasma cutters from the late 1980s to the 1990s, giving the plasma cutter more flexibility to cut a variety of shapes” on demand. ” based on a set of programmed instructions. in the numerical control of the machine.
However, these CNC plasma cutters are usually limited to cutting flat sheet steel samples and parts, using only two axes of motion (known as X Y cutting). Some plasma cutter manufacturers build CNC cutting tables, and some cutter manufacturers have built-in table tops. The CNC table allows a computer to control the torch tip to produce clean cuts. State-of-the-art plasma CNC equipment is capable of multi-axis cutting of thick materials, enabling complex bead welding capabilities not possible.
For thinner materials, plasma cutting is gradually being replaced by laser cutting, mainly due to the superior hole cutting ability of laser cutting machines.
