A CNC Press Brake is a machine used in manufacturing to bend and shape metal sheets. It operates using a computer numerical control (CNC) system, which allows for precise and repeatable bending operations. The machine uses a punch and die setup to create various angles and shapes in the metal, making it essential for producing components in industries like automotive and aerospace. The CNC system enhances the efficiency and accuracy of the bending process, reducing the need for manual adjustments. Operators can input specific designs and parameters, ensuring consistent results across multiple pieces. This technology streamlines production and improves overall quality in metal fabrication.
