Unlike traditional manual machines, this equipment allows the operator to directly program part geometry into the CNC control system. Once the program is set, the machine automatically adjusts key parameters such as back gauge position, bending angle, ram stroke, speed, and tonnage. As a result, every bend is executed with consistent precision, even in continuous batch production environments. This makes it an essential machine for modern sheet metal fabrication industries that require both flexibility and productivity.
The slitting system is designed for precise straight-line cutting of sheet metal. It uses a 1.1 kW driving motor combined with a Ø80 mm wheel slitting blade made of Cr12MoV material, ensuring durability and cutting accuracy. The system supports material thicknesses up to 1.2 mm and operates at a stable speed of approximately 0.8 m/min. A steel rope guiding system ensures smooth movement and consistent alignment during slitting operations.
The CNC Folding Machine, also known as a CNC Press Brake or CNC Slitter Folder, is a modern and highly automated sheet metal forming system designed for precision bending, folding, and slitting operations. It integrates an advanced Computer Numerical Control (CNC) system that automates the entire forming process, helping manufacturers achieve higher efficiency, improved accuracy, and stable repeatability in mass production.
Advanced CNC Control System for Intelligent Manufacturing
The CNC Folding Machine is equipped with a user-friendly CNC control system that significantly simplifies complex forming tasks. Operators can draw profiles directly on the touchscreen interface, adjust bend angles, set bending sequences, and simulate the entire production process before execution. In addition, the system supports offline programming and DXF file import, which further improves workflow efficiency and reduces preparation time.
There are typically two control options available, including a luxury graphical CNC system and a traditional digital control system. Both are designed to improve usability and reduce operator dependency. With real-time feedback and intelligent programming functions, the machine ensures accurate results while minimizing human error during production.
Strong Structural Design and Stable Hydraulic System
We construct the machine body using high-strength steel plates and a heavy-duty welded box structure, which delivers excellent rigidity and long-term stability. Even during continuous high-load operation, the structure maintains accuracy and effectively reduces deformation. Dual hydraulic cylinders drive the folding beam, which ensures smooth operation and balanced force distribution during sheet metal bending.
The hydraulic system combines a high-quality pump and motor with a large oil reservoir to generate stable pressure output and improve energy transmission efficiency. At the same time, we integrate overload protection systems into both the electrical and hydraulic components to enhance operational safety and reliability. High-load spherical bearings support key pivot points, which increases durability and reduces mechanical wear, while the clamping system firmly holds the material throughout the forming process.

Working Process of CNC Slitter Folder Machine
Before operation, the sheet metal is accurately measured and positioned on the working platform or conveyor system. Depending on the material type and thickness, the machine can process carbon steel, stainless steel, aluminum, and galvanized sheets with consistent precision. The CNC system then guides the operator through programming, where bending angles, lengths, and forming sequences are defined directly on the touchscreen interface.
During the sheet metal bending process, the back gauge first positions the sheet according to the programmed coordinates. After positioning, the clamping beam securely fixes the material in place to prevent movement. The folding beam then rotates upward under hydraulic power to achieve the required bending angle. This ensures high accuracy and repeatability, even for complex geometries.
In addition to bending, the machine also integrates a slitting system. The sheet is positioned and clamped according to the programmed cutting line, and a guillotine-style blade performs a clean horizontal cut across the material. This allows the machine to complete both forming and cutting operations in one continuous workflow, significantly improving production efficiency and reducing material handling time.
Slitting Device and PLC Control System
The machine is controlled through a PLC-based system that integrates a custom electric control board, SINEE inverter, and Weilun touchscreen interface. Operators can input commands directly through the touch panel, including angle programming and process control. The system also includes encoder testing for precise feedback, manual slitting control, and a full emergency stop system that ensures stable operation and enhanced safety in industrial environments.
Safety is a key consideration in the design of the CNC Folding Machine. It is equipped with a laser safety light curtain, two-hand operation system, emergency stop buttons, and hydraulic overload protection. These safety features work together to reduce operational risks and ensure safe interaction between the operator and the machine.
This equipment is widely used in industries such as steel structure manufacturing, construction, HVAC duct production, metal roofing systems, electrical enclosures, and general sheet metal fabrication. Its ability to combine bending, folding, and slitting into one automated system makes it highly valuable for companies aiming to improve production efficiency while maintaining strict quality standards.
The CNC Folding Machine / CNC Slitter Folder is a highly advanced and versatile solution for modern sheet metal processing. With its intelligent CNC control system, robust hydraulic structure, and integrated bending and slitting functions, it delivers exceptional precision, efficiency, and reliability. It is an ideal choice for manufacturers seeking to upgrade their production capability and achieve consistent high-quality output in competitive industrial markets.
