CNC Underwater Plasma Cutting Machine


1.This CNC plasma cutter has a water level of cutting platform. Please charge the water bed by opening the fan blower through gas valve before cutting, then the water level will rise rapidly.
2.This CNC underwater plasma cutting machine possesses the functions of CNC plasma, CNC flame and strip flame cutting. The cutting thickness is not limited to thick plate, medium and thin plates are also available.
3.When the water submerges the steel plate, the gas valve will be closed and the water level will stop.
4.This plasma cutter can be used for cutting mild steel and stainless steel, and it is not suitable for cutting aluminum and magnesium.
5.When this CNC plasma cutting machine is running, the water will absorb metallic dust and arc completely
6.The CNC plasma cutter has little distortion, but the manufacturing cost of the water bed is relative higher.


1.The CNC system can choose from American Hypertherm, American Bruney or Beijing Stuart
2.This CNC underwater plasma cutting machine can be equipped with different kinds of plasma supply, such as American Hypertherm, American Thermadyne, Germany Kjellberg or domestic plasma power.
3.For the key parts, we use the France Schneider’s servo drive system, reducer of Germany NEUGART, towline from Germany IGUS, and SIEMENS or ABB’s elements.
4.This CNC plasma cutter can be configured with two types guide rails, 24kg/m and 38kg/m. It also can be selected according to the requirement of the customers.
