CNC control system
It adopts an imported all-electric servo closed-loop control system with bus control. It can perform multi-axis concurrent linkage intelligent control to ensure smooth bending action and high mechanical operation coordination.
Automatic CNC Panel Bender (Press Arm Type) | STON-C2 Series
Plieuse de panneaux CNC (type à bras presseur)
Fully automatic bending centers for multi-angle panels.
CNC panel bender (press arm type) designed specifically to solve that problem at the production level. It's not a general-purpose bending machine. It's a purpose-built automatic panel bender for manufacturers who produce panel-type sheet metal parts at volume — enclosures, cabinets, doors, frames, and similar formed parts — and metal furniture industries who need reliable, high-accuracy sheet metal bending in production environments.The machine brings together a rigid machine body, all-electric servo control, multi-axis linkage, and a disturbance compensation system to deliver consistent CNC sheet metal bending results without constant manual recalibration.

Product Advantages
1. Multi-Axis Concurrent Control
15/18-axis servo closed-loop system completes positive bends, negative bends, Z-profiles, and box-forms in a single cycle — no manual repositioning required between bends.
2. Rapid Compensation Adjustment
Built-in compensation device corrects bending accuracy along the full bending line significantly faster than shim-type systems, reducing changeover downtime between product types.
3. Full Annealing on All Structural Parts
Every machine bed and structural component undergoes documented full annealing to eliminate internal stress, preventing dimensional drift over years of high-cycle operation.
4. All-Metal Lubrication Lines
Metal lubrication pipelines eliminate burst and crack risk common in plastic-tubing systems. Rated maintenance-free for the machine’s full service life.
5. Ground Lead Screw and Roller Guides
Factory-ground lead screws and pressure-block-mounted roller guides sustain ±0.1 mm dimensional accuracy and ±0.5°/m angular accuracy across extended production runs.
6. Automation Docking Interface
Standard docking port compatible with robotic arm, gantry, and truss-type loading systems. Supports future line automation upgrades without replacing the panel bender.
