Engineering Details That Ensure Long-Term Precision

  • STON CNC Flexible Edge Bending Machine catalog - annealed stress relieved frame

    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.

  • STON CNC Flexible Edge Bending Machine catalog - axis servo control

    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.

  • STON CNC Flexible Edge Bending Machine catalog - maintenance free copper pipe lubrication

    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.

  • STON CNC Flexible Edge Bending Machine catalog - forged blank holders

    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.

  • STON CNC Flexible Edge Bending Machine catalog - high precision flip up structure

    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.

  • STON CNC Flexible Edge Bending Machine catalog - patented suction cup feeding

    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.
