What are the two main types of press brakes?

• A. Hydraulic and Pneumatic
• B. Mechanical and Hydraulic
• C. Mechanical and Electric
• D. Hydraulic and Electric

Answer: (B)

Press brakes are categorized by how they generate bending force. The two main families are mechanical and hydraulic. In a mechanical press brake, a crank and flywheel system delivers the bending force in fast, repeatable strokes, making it ideal for high-speed production of lighter to medium-thickness parts with consistent results. Hydraulic press brakes use hydraulic cylinders to push the ram, which provides very high bending force with smooth, controllable motion and is better suited for heavy or thick materials and complex bends, though it typically runs more slowly than mechanical ones. Electric or servo-electric systems exist as modern alternatives, but the traditional two main types are mechanical and hydraulic.
