Backgauge System for CNC Press Brakes | Specifications and Verification

Product Specifications

Technical details and manufacturing context for Backgauge System

Definition

The backgauge system is a critical component of CNC press brakes that precisely positions sheet metal or plate material against a reference point to ensure accurate bend locations. It consists of mechanical stops, linear guides, servo motors, and control systems that work together to achieve repeatable positioning for multiple bends in a single setup. The system is designed for use in fabricated metal product manufacturing, where it contributes to the efficiency and accuracy of bending operations. Key components include aluminum alloy and steel structural parts, as well as precision linear bearings. The system offers positioning accuracy of ±0.05 mm and repeatability of ±0.02 mm, both verified according to ISO 230-2. It provides a maximum stroke of 500 mm and a maximum speed of 300 mm/s. The axis count ranges from 2 to 6, allowing for flexibility in handling complex parts. The control voltage is 24 V DC ±10%, compliant with IEC 61131-2. The operating temperature range is 0–50 °C, tested per IEC 60068-2-1. Protection class varies from IP54 to IP65, depending on the configuration, as per IEC 60529. The maximum load capacity is 100 kg, and the system weight ranges from 150 to 300 kg, depending on axis configuration. The guide rail type is linear, conforming to ISO 12090-1, and the drive type is servo for dynamic positioning. These specifications are reference values; actual model-specific values and standards must be verified with the legal manufacturer or supplier.

Working Principle

The CNC controller sends positioning commands to servo motors, which drive the backgauge fingers along linear guides to predetermined positions. Material is manually or automatically fed against these stops, ensuring consistent bend locations across multiple workpieces. Advanced systems may include multiple axes, programmable fingers, and automatic adjustment capabilities.
