Machine Structure
An all-steel welded structure is used to build the machine frame, which also includes the bed and moving beam. Its symmetrical design keeps the weight evenly balanced on both sides of the column. A stable support is provided by reinforced internal ribs and a well-proportioned connection between the main drive housing and columns. The overall structure is optimized through finite element analysis to ensure sufficient strength, rigidity, and long-term stability. To prevent deformation after machining, the frame undergoes full annealing to eliminate internal stress, followed by one-time precision machining using large five-face machining centers, ensuring high geometric accuracy and consistent long-term performance.
-
Main Drive System
The main drive system transmits bending force through heavy-duty ball screws and bearings, designed for long service life. The key components are sealed and protected from dust and external contamination, helping maintain stable performance over time.
-
Crowning System
The worktable is equipped with an integrated high-precision crowning structure, featuring a lower crowning unit and a segmented upper adjustment mechanism. A front-mounted fine adjustment system with scale indication allows intuitive and precise setup. The system is supported by an integrated motor drive, aluminum alloy protection plate, and scale ruler, ensuring consistent bending accuracy across the full length.
-
Backgauge System
The backgauge is designed with four controlled axes and is powered by AC servo motors paired with high-precision gear reducers. Controlled by the CNC system, it moves quickly and accurately to the required position. During operation, the backgauge can automatically retract to avoid interference with the workpiece, ensuring smooth and safe bending.
-
Press Brake Tooling
All press brake tooling is heat-treated and precision-ground, with tight tolerances maintained on all critical dimensions to ensure accurate bending results. High-precision tooling reduces the need for secondary corrections, lowering processing costs while extending tool life compared to standard tooling.
-
Electrical System
The electrical system includes self-diagnostic functions, allowing operators to monitor machine status in real time through indicators and display screens. The enclosed electrical cabinet uses vertical airflow cooling to maintain stable operation of electrical components. The press brake is also equipped with alarm systems and emergency stop functions to prevent damage in case of unexpected conditions, with fault information clearly displayed for quick response.

CNC Control System
The SL100-P CNC system is built with an industrial-grade motherboard and advanced bending algorithms, ensuring stable performance even in demanding industrial environments. It has passed EMC compatibility as well as high and low temperature testing to maintain reliability under varying conditions. Equipped with a 15-inch high-definition touchscreen, the system features a clear and intuitive interface with direct programming capability, allowing operators to start production by simply inputting key parameters such as backgauge position and bending angle, improving efficiency while reducing operational complexity.
