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.
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.
Common Materials
Aluminum alloy, Steel, Precision linear bearings

Engineering Reasoning
0.01-10 mm positioning accuracy at 0.001 mm resolution
Positioning error exceeding ±0.05 mm from commanded position
Design Rationale: Ball screw thermal expansion exceeding 11.7 μm/m·°C coefficient at ΔT>15°C, or servo encoder pulse loss >0.1% of commanded pulses
Risk Mitigation (FMEA)
Trigger Servo motor resolver contamination with metal particles >5 μm diameter
Mode: Position feedback signal phase shift causing 0.02-0.5 mm positional oscillation
Strategy: IP67-rated resolver housing with ferrofluidic shaft seals and HEPA-filtered positive pressure purge system
Trigger Linear guideway lubrication starvation with oil film thickness <1 μm
Mode: Stick-slip friction causing 0.03-0.8 mm positioning hysteresis
Strategy: Forced lubrication system with 0.1 MPa oil pressure monitoring and 40 μm filtration
