Backgauge fingers are critical components of a press brake, designed to accurately position the sheet metal during the bending process. They determine the bend location by guiding the material to the correct distance from the tooling, ensuring consistent and repeatable results.

Types and Functions

Manual Backgauge Fingers

Adjusted by hand, manual backgauge fingers are simple, cost-effective, and suitable for basic bending tasks or small-scale production. They require more operator input and setup time but are reliable for straightforward applications.

Electric Backgauge Fingers

Powered by electric motors and controlled via the CNC system, electric backgauges offer faster and more precise adjustments than manual types. They improve setup efficiency and are well-suited for medium-volume production.

Servo Backgauge Fingers

Equipped with high-speed servo motors, servo-controlled backgauge fingers provide the highest level of accuracy, speed, and repeatability. Ideal for complex bending sequences and automated production lines, they allow real-time positioning adjustments and support multi-axis configurations for advanced forming operations.

Overall, the choice of backgauge system depends on the level of automation, accuracy, and production efficiency required by the application. Each type plays a vital role in improving part quality, reducing operator error, and optimizing workflow.
