High accuracy press brake for precision bending

Core Precision: Engineering That Leaves No Room for Error

At the heart of this press brake lies a high-performance servo-hydraulic drive system—a leap beyond conventional hydraulic setups. Unlike standard machines that rely on fixed pressure, this system uses closed-loop feedback to adjust force and ram movement in real time, delivering bending force ranging from 30T to 300T with ±1% accuracy. This level of control is critical for bending thin-gauge alloys (as thin as 0.1mm) or high-strength metals (such as titanium or Inconel) without distortion, a common pitfall in less precise equipment.

The ram itself is guided by high-precision linear roller bearings (not sliding guides), ensuring vertical movement accuracy of ±0.005mm per 1000mm of stroke. Paired with a CNC-controlled backgauge featuring dual-ball screws and servo motors, the machine achieves backgauge positioning accuracy of ±0.01mm—meaning every bend aligns perfectly with the last, even across 10,000+ cycles. For angle precision, advanced angle measurement sensors (integrated into the ram) deliver ±0.05° accuracy, eliminating the need for post-bend calibration.

Intelligent Control: CNC Technology for Seamless Precision

Precision is only as reliable as the system controlling it—and this press brake’s 19-inch touchscreen CNC controller is designed for both accuracy and ease of use. Pre-loaded with a library of 10,000+ bending programs (including material-specific parameters for steel, aluminum, copper, and specialty alloys), it lets operators recall or modify setups in seconds. The controller’s 3D simulation feature is a game-changer: it renders the entire bending process in 3D, allowing users to visualize bends, check for collisions, and optimize tool paths before pressing—reducing material waste (a critical saving for high-cost precision metals) and setup time by up to 60%.

For complex parts requiring multiple bends (such as box enclosures or stepped components), the controller supports multi-axis synchronization (up to 8 axes, including X, Y1, Y2, Z, and R axes). This ensures each bend is executed in perfect sequence, with the backgauge and ram moving in harmony to maintain tolerances even for intricate geometries. Advanced users can also program custom bending formulas, while beginners benefit from guided setup wizards that simplify parameter input.

Precision-Optimized Tooling and Worktable

Even the most advanced drive system can’t deliver precision without the right tooling—and this press brake comes equipped with ultra-precision ground tooling as standard. The upper punches and lower dies are machined from hardened alloy steel (HRC 58-62) with a surface finish of Ra 0.4μm, minimizing friction and ensuring clean, burr-free bends. Each tool is laser-marked with its dimensions and bend radius, making selection quick and error-free.

The worktable is equally precision-focused: it features a segmented design with replaceable precision inserts that align perfectly with the tooling, eliminating gaps that could cause material shifting. The table’s surface is coated with a wear-resistant, non-marring finish to protect delicate materials (such as polished aluminum or brass) while maintaining flatness tolerance of ±0.02mm over the entire table length (available in 1.5m to 4m options). For thin materials prone to warping, an optional micro-bending kit allows for bends as small as 5° with consistent accuracy.

Durability: Sustaining Precision for Years

Precision must last—and this press brake is built to maintain its accuracy through years of heavy use. Its frame is constructed from high-strength cast iron, stress-relieved and normalized to eliminate internal stresses that cause deformation over time. The hydraulic system uses high-pressure seals (rated for 350bar) and a multi-stage oil filtration system that keeps fluid clean, preventing wear on valves and cylinders.

The electrical components are housed in an IP65-rated cabinet, shielding them from dust, coolant, and metal shavings common in fabrication shops. Even the backgauge’s ball screws are protected by telescopic covers, ensuring smooth operation and consistent positioning for decades. Regular maintenance is simplified by easy access to components and a built-in diagnostic system that alerts operators to potential issues before they affect precision.
