The automatic tool changing panel bender helps factories reduce repeated manual tool arrangement and improve workpiece changeover efficiency. From drawing import and process simulation to tool arrangement and bending execution, the machine supports a more flexible and organized sheet metal bending workflow.
Automatically switches upper blank holders according to imported drawings, reducing manual tool setup for flexible production.
Identifies bending features, reverse-unfolds sheet metal, plans the process, and simulates bending before production.
Optional auxiliary bending tools support positive and negative folding for local bends and complex panel structures.
The upper blank holder uses 38CrMoAl material for wear resistance and stable long-term bending performance.
The 5mm thinnest tool blade supports 5mm tool assembly accuracy with ±0.5mm tool changing tolerance.
Wraparound tool mounting and pneumatic locking help improve tool stability during repeated bending.
Our automatic tool changing CNC panel bender is suitable for sheet metal parts that require frequent product switching, different bend lengths, and complex forming structures. It is ideal for cabinet panels, enclosure parts, ventilation panels, stainless steel equipment panels, and customized sheet metal components used in multi-variety and small-batch production.
The STON automatic tool changing panel bender is designed around flexible tooling, stable machine structure, and reliable motion control. Key components include the automatic tool changer, 3D bending simulation system, auxiliary bending tools, 38CrMoAl upper blank holder, wrapped tool mounting structure, heavy-duty fuselage, and metal lubrication system.
The fuselage’s mainboard is 80mm thick. The fuselage and all structural components undergo annealing, four-step machining, and lean assembly. It is independently designed and manufactured according to the tool changing system’s requirements, ensuring stability and high efficiency.
Automatic tool changer refers to the automatic switching of the upper blank holder. STON automatic tool changer panel bender automatically calculates the arrangement of the upper blank holder according to the drawings, which is convenient for flexibly switching the bending requirements of the workpiece.
The 3D simulation system automatically identifies bending features, unfolds the sheet material in reverse, and plans the bending process, displaying a complete animated simulation of the entire bending action on the screen. It confirms process feasibility and performs collision detection, eliminating the need for physical trial bending.
An optional auxiliary bending tool can be selected according to the workpiece requirements, supporting both positive and negative folding. This is to meet the needs of partial bending that is shorter than the length of the entire sheet of material.
The upper blank holder is made of 38Cromoal material, making it wear-resistant and durable. All circuits and air passages are protected by guide plates, preventing compression and friction during W-axis movement.
The tool changing accuracy is determined by the thickness of the thinnest tool in the tool assembly. The thinnest tool in the panel bender of the STON automatic tool changer is 5mm thick, the tool changing accuracy is 5mm, and the tool changing accuracy tolerance is ±0.5mm.
All tools are mounted in a wraparound design, and with the help of a pneumatic locking device, bending is more stable and precise.
All components, including metal lubrication lines, grinding lead screws, and roller guides for pressure block mounting, are of our company’s high specifications.

A CNC panel bender with automatic tool changer is a flexible sheet metal bending center that automatically switches upper blank holders according to different workpiece requirements. It helps reduce manual tool setup and supports faster product changeover.
After the drawing is imported, the system calculates the required upper blank holder arrangement. The automatic tool changing system then switches tools according to the bending process, helping operators handle different panel structures more efficiently.
Yes. The 3D bending simulation system can identify bending features, reverse-unfold the sheet metal, plan the bending process, and display the full bending action on screen. This helps check process feasibility and collision risk before real bending.
Auxiliary bending tools are used for local bends that are shorter than the full sheet length. They support both positive and negative folding, making the machine more suitable for complex sheet metal panel structures.
It is suitable for electrical cabinets, switchgear enclosures, metal office furniture, ventilation equipment, stainless steel kitchen equipment, medical and laboratory furniture, and custom sheet metal fabrication.
Please provide sheet material, thickness, maximum panel size, bending height, product drawings, tool changing requirements, production capacity, and automation needs. STON will recommend a suitable configuration based on your real production process.
Of u nu een bestaande lijn upgradet of een nieuw project start, STON past een CNC oplossing aan voor uw productie.
