CNC flame cutting machine, CNC flame cutting machine has good performance,it can cut cut large thick carbon steel, low cost, but there are many disadvantges, like deformation, cutting precision is low and cutting speed also low, cutting preheating time is long, perforation time is long, it is difficult to adapt the requirments of the automatic operation. Its application is mainly limited on carbon steel, large thickness plate, in the medium and thin carbon steel plate cutting will area, it is graduall replaced by plasma cutting.
