Product Specifications

Technical details and manufacturing context for Back Gauge System

Definition
The Back Gauge System is a critical component of industrial metal bending presses that precisely positions sheet metal or plate material against a reference point before the bending operation. It ensures accurate bend locations by controlling the distance from the material edge to the bending line, enabling repeatable and precise metal forming processes.
Working Principle
The system uses mechanical, hydraulic, or servo-driven mechanisms to move a gauge finger or stop block to a programmed position. Material is manually or automatically fed against this stop, establishing the exact location for the bend. Modern systems incorporate digital controls, encoders, and programmable logic for automated positioning.
