CNC flame/plasma Cutting machine and CNC underwater plasma cutting machine are high efficient and energy-saving cutting equipment. They are suitable for the precise cutting for carbon steel, stainless steel and nonferrous metal plates with different thickness and can promote the utility of plates and can save time & materials. CNC flame cutting machine has good performance in cutting carbon steels with 5-300mm thick, while for CNC plasma cutting machine to cut stainless steels, carbon steels and nonferrous metals with thickness 0.5-150mm. CNC underwater plasma cutting machine equipped with water platform can greatly reduce pollution such as smoke, dust, arc, harmful gas, noise etc,. caused by plasma cutting, which could have good environmental protection.
