There are various types of brake machines, including mechanical and hydraulic press brakes. Mechanical press brakes operate using a system of gears and levers, providing fast operations for high-volume tasks. Hydraulic press brakes, on the other hand, utilize hydraulic force, allowing for more precise control over the bending process and enabling the handling of thicker materials. Some advanced models incorporate CNC (Computer Numerical Control) technology, which enhances efficiency by allowing operators to program specific bends and repetitions, minimizing human error.
