Causes of thermal deformation of NC plasma flame cutting

Used CNC plasma cutting machine or CNC flame cutting machine cutting process, usually cut after completion will find some deformation of the shape of the workpiece, this is what we mean by CNC cutting machine manufacturers of thermal deformation; CNC flame cutting machines in sheet metal rolling and cooling to avoid residual stress. This is because, in using NC, ion cutting machine or NC flame cutting machine cutting process in the, gantry type NC cutting machine due to by local high temperature heat factors of effect, metal plate will along cutting of direction occurred expansion, portable NC cutting machine expansion Hou of metal plate around of mother Board will will by must of limit, metal plate in incision edge of location Shang small NC cutting machine occurred larger of stress role, led to cutting artifacts of deformation.
