Press brakes are machines used in sheet metal forming to bend sheet metal or metal sheets into specific shapes and angles. A press brake usually consists of a bending machine and a punching machine. The bending machine has an upper and a lower bending tool edge between which the material is clamped and bent. The punching machine allows holes or cutouts to be punched in the material. Press brakes are used in various industries and applications, such as automotive, aerospace, engineering, metal fabrication, and heavy industry. The choice of the appropriate press brake depends on various factors, such as the thickness of the material, the size of the sheets, the required bending angles and the type of bending operations. There are different types of press brakes, such as hydraulic press brake, mechanical press brake and servo-electric press brake. Hydraulic press brakes are widely used in heavy industry, while mechanical press brakes are used in smaller workshops and mass production. Servo-electric press brakes are generally faster and more accurate than hydraulic or mechanical press brakes, and are often used in high-precision applications.
