Due to the unique characteristics of desktop CNC plasma cutting machine such as high speed, high efficiency, high kerf smoothness, and wide applicable cutting range, CNC plasma cutting has been widely used in machinery, shipbuilding, steel structures, automobiles, pressure-sensitive industries, etc.And is gradually replacing flames. Cutting dominance in a certain field. As a high-precision mechanical instrument, the plasma cutting machine has high precision requirements for cutting products. There are many precautions for the operation of the plasma cutting machine, which require the operator's attention.

1. Principles of plasma cutting technology

CNC plasma cutting machine is a processing method that uses the heat of high-temperature plasma arc to partially melt (and evaporate) the metal at the incision of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form the incision.

2. Comparison between plasma cutting and flame gas cutting

CNC plasma cutters are only effective on metals that can act as conductors - mild steel, aluminum and stainless steel being typical examples. Operators will experience high speed, deeper cuts when cutting mild steel. Flame gas cutting cuts metal by burning high temperatures, or by oxidizing it. Therefore, its application scope is limited to the type of ferrous metals that can be treated by oxidation technology. Metals such as aluminum and stainless steel will form oxides that restrict further oxidation. This makes traditional flame gas cutting impossible to handle this type of material. Plasma cutting does not rely on oxidation treatment and can

To effectively cut aluminum, steel and some other conductive metals.

And different types of gases can be used in plasma cutting. Currently, most people use compressed air for plasma cutting. in most cities

Air compressors are available in the city. Therefore, plasma cutting does not require gases such as flammable gases and compressed oxygen as operating gases. When cutting thick plates, plasma

Flame cutting is more expensive than flame gas cutting, and flame gas cutting does not require a connection to power and compressed air, which makes it easier to use for some users. flame

Gas cutting is faster than plasma cutting when cutting thicker steel, but CNC plasma cutting machines cut much faster than flame cutting when cutting plates.

Cutting with higher efficiency and better results!

3. Plasma cutting processing range

CNC plasma cutters are ideal for cutting steel and non-ferrous metals with thick bases less than 1 inch. Flame gas cutting requires the operator to carefully control the cutting speed to maintain the oxidation process. CNC plasma cutting machines are more flexible in this regard. There are some applications where plasma cutting is excellent. For example, cutting metal sheets is impossible when using flame gas cutting. In addition, compared with mechanical cutting methods, CNC plasma cutting machines are much faster and easier to perform non-linear cutting. Cutting aluminum, copper, stainless steel and other metal materials is the strength of CNC plasma cutting machines!
