A CNC press brake is a type of machine press that uses precise computer controls to bend sheet metal into different shapes. This machine uses force, which is typically hydraulic, to form predetermined bends by clamping the workpiece between a matching punch and die.The CNC aspect of the press brake means it is controlled by a computer system. The operator inputs the specifications (like the angle and dimensions of the bend), and the machine performs the task with a high level of accuracy and repeatability. This automation reduces the likelihood of human error and increases the efficiency of the overall bending process.
