What is "press brake"

n. A machine used in cold-forming sheet metal or strips of metal into desired profiles.

A press brake is a machine tool for bending sheet and plate material, most commonly sheet metal. It forms predetermined bends by clamping the work piece between a matching punch and die.

Typically, two C-frames form the sides of the press brake, connected to a table at the bottom and on a movable beam at the top. The bottom tool is mounted on the table with the top tool mounted on the upper beam.
