Plasma cutting was actually developed before laser cutting and began to be used in the 1950s. Prior to this, metal was flame cut, which is exactly what it sounds like. However, some metals could not be flame cut, like stainless steel, aluminum, or copper, and so plasma cutting was invented. The plasma cutting method involves a highly concentrated channel of electrically conductive gas that acts as a vessel to transmit energy from a power source to the material being cut by means of moving through a plasma torch. Like a laser cutter, a cnc high definition plasma cutting machine ultimately slices through metal by melting it.

Plasma cutting is a low-cost cutting which, provides high speed and precision by way of a melting process. In which, a jet of ionized gas is used to melt and expel material from the cut. Typical materials cut with a plasma torch include steel, Stainless steel, aluminum, brass, and copper, although other conductive metals may be cut as well.

Stainless steel products have special physical properties, so CNC plasma cutting machines have the following advantages in cutting, precisely because stainless steel products have also driven the rapid development of cnc high definition plasma cutting machine.

The particularity of stainless steel plate, its main processing method is hot and cold processing forming method. Cold processing, often slow and inefficient, is mainly used for cutting and processing of specifications and shapes

According to different circumstances, the cutting effect is not the same, and the cost is also slightly higher or lower.

The thermal processing method can use CNC plasma cutting, plasma cutting speed is fast, high efficiency, low cost, to meet the needs of enterprises. And cold working methods often cannot

Meet the production needs of enterprises. Therefore, more and more enterprises prefer CNC plasma cutting machines.

Key Advantages of cnc high definition plasma cutting machine

Plasma cutting is comparatively cheap for medium thickness cuts
High-quality cutting for thicknesses up to 50mm
Maximum thickness of 150mm
Plasma cutting can be carried out on all conductive materials, in contrast to flame cutting which is only suitable for ferrous metals.
When compared to flame cutting, plasma cutting has a significantly smaller cutting kerf
Plasma cutting is the most effective means of cutting medium thickness stainless steel and aluminum
Faster cutting speed than oxyfuel
CNC plasma cutting machines can offer excellent precision and repeatability.
Plasma cutting can be carried out in the water which results in smaller heat-affected zones as well as minimizing noise levels.
Plasma cutting can cut more complex shapes as it has high levels of accuracy. Plasma cutting results in minimal dross as the process itself gets rid of excess material, meaning very little finishing is required.
Plasma cutting does not lead to warping as the fast speed significantly reduces the heat transfer.
Main Disadvantages of Plasma Cutting

Best cnc plasma cutting machine results in a much larger heat affected zone than laser cutting (however, as previously mentioned, this can be mitigated by cutting in water)
With thinner sheets and plates the quality is not as good as with laser cutting
Laser cutting is more precise
Cannot cut thicknesses as high as waterjet or flame cutting
Plasma cutting causes a wider kerf than laser cutting
