CNC Press Brake | Electro-Hydraulic & All-Electric Servo | STON

Servo Electric Press Brake vs Electro-Hydraulic Press Brake

Choose an all-electric servo press brake when repeatability, lower energy use and fast response matter most. Choose an electro-hydraulic CNC press brake for varied tonnage, thicker sheets and general production. For long-bed applications, the T160-4100 servo motor driven press brake fits 4100mm bending with stable positioning and high-load control.

Structural and Mechanical Details Built for Long-Term Reliability

  • STON CNC CNC Press Brake catalog - annealed high strength integral frame - view 02

    Annealed High-Strength Integral Frame

    The machine body is made from high-strength integrally welded material and undergoes annealing, shot blasting, and aging treatment to eliminate internal stress — providing sufficient rigidity, minimal deformation, and stable long-term working accuracy under eccentric loads.

  • STON CNC CNC Press Brake catalog - mechanical deflection compensation

    Mechanical Deflection Compensation

    The built-in mechanical deflection compensation system automatically compensates for slider and worktable deformation under bending load, ensuring uniform bending angles and higher straightness along the entire workpiece length.

  • STON CNC CNC Press Brake catalog - full closed loop grating ruler feedback - view 02

    Full Closed-Loop Grating Ruler Feedback

    High-precision grating rulers detect position signals in real time and feed them back to the CNC system, ensuring high positioning accuracy and repeatability — guaranteeing consistent bending angles across every part in a production run.

  • STON CNC CNC Press Brake catalog - multi axis cnc back gauge - view 02

    Multi-Axis CNC Back Gauge

    Multi-axis CNC linkage with automatic positioning and multi-segment programming enables fast, accurate back gauge positioning for complex workpieces requiring multiple sequential bending operations.

  • STON CNC CNC Press Brake catalog - laser safety protection system - view 02

    Laser Safety Protection System

    A real-time laser safety monitoring system detects interference in the hazard zone and immediately stops the machine — providing sensitive, reliable protection for operators during high-speed bending cycles.

  • STON CNC CNC Press Brake catalog - robotic arm integration ready - view 02

    Robotic Arm Integration Ready

    Both series are expandable with automatic loading and unloading systems compatible with most robotic arms on the market, enabling unmanned, continuous production and reducing manual labor in high-volume bending operations.
