CNC Edge Bending for High-Consistency Sheet Metal Forming

STON's flexible edge bending machines are designed specifically for manufacturers processing thin sheet metal panels. Built on an Industry 4.0 architecture with an all-electric servo closed-loop control system supporting up to 25 axes of concurrent linkage, these machines deliver high speed, consistent workpiece forming, low power consumption, and minimal daily maintenance — with no molds required. Both standard and automatic loading/unloading configurations are available to match your production scale.

Choose the Right Flexible Edge Bending Machine for Your Production

Engineering Details That Ensure Long-Term Precision

Annealed & Stress-Relieved Frame

The fuselage, feeding platform, and all structural components undergo annealing and shot blasting after welding. Finite element analysis guides the structural design to eliminate deformation under long-term heavy-load operation.
25-Axis Servo Control

An imported all-electric servo closed-loop control system supports up to 25 axes of concurrent linkage, enabling smooth execution of complex multi-step bending combinations at industry-leading cycle speeds.
Maintenance-Free Copper Pipe Lubrication

The lubrication pipeline is maintenance-free throughout the entire equipment lifecycle, eliminating the risk of plastic pipeline bursting and reducing unplanned downtime.
42CrMo Forged Blank Holders

Blank holders are machined from 42CrMo forged material for high strength and hardness. The entire tool set is precision-machined as a matched set to guarantee angle consistency across the full bending length.
High-Precision Flip-Up Structure

Both ends of the flip plate are hinged to the frame using double-row tapered roller bearings or cross roller bearings, with minimal radial and axial clearance to prevent loosening or shaking under long-term heavy loads.
Patented Suction Cup Feeding

The 360° rotating suction cup feeding system holds a utility model patent. Simple to operate and safe, it significantly reduces loading and unloading time while improving operator safety on the production floor.
