CNC Punching is a process for sheet metal manufacturing that is carried out by punch press machines. The process can either have a one head and tool rail design or multi-tool turret design. Programmed to move a sheet of metal in a 2-axis direction, CNC punching machines position the metal sheet under the punching ram as accurately as possible so that it will be ready to punch a hole or form the metal. Similar to most metal production machinery, components of a punch press include a bed, table punch, die, a rotating turret, and a frame.
