Large CNC flame steel plate cutting


Flame steel plate cutting is an economical way to process low-carbon steel and low-alloy steel, and it is also suitable for welding joints. It is one of the main processing methods in the metal industry.



Large CNC plasma steel plate cutting


Used to cut materials that are not suitable for flame steel cutting, such as high alloy steel or aluminum. Today, it is also used to cut thinner low-alloy steel plates.



Large CNC laser cutting equipment


The CNC laser beam is focused on the material through the hole of the cutting nozzle, heating the material and melting it. The cutting gas usually sprayed in the same direction as the cutting nozzle blows away the slag at the same time.
