CNC Motorized Crowning System

The CNC Motorized Crowning System automatically compensates for table deflection during the bending process, ensuring consistent bending angles across the entire length of the workpiece. Controlled directly by the CNC system, the crowning value is automatically calculated and adjusted according to material thickness, bending length, tooling configuration and bending force.

Compared with manual compensation systems, the motorized crowning system delivers higher precision, faster setup and improved production efficiency. It is an essential feature for high-accuracy CNC press brakes, especially when processing long sheet metal parts and demanding precision bending applications.

DSP Laser Safety Protection System（Optional）

The DSP Laser Safety Protection System is an advanced safety device designed for CNC press brakes, providing real-time operator protection without reducing productivity. Using high-precision laser technology, the system continuously monitors the area beneath the punch and instantly stops machine movement when an obstruction is detected.

Unlike traditional light curtains, the DSP laser protection system allows safe high-speed ram movement during most of the bending cycle while maintaining full compliance with international safety standards. This significantly improves both operator safety and production efficiency.

Quick Clamping System

The Quick Clamping System enables fast and secure installation of press brake punches, significantly reducing tooling changeover time and improving production efficiency. Designed for precision CNC press brakes, it ensures accurate tool positioning, stable clamping force and safe operation during high-speed bending processes.

With its user-friendly design, operators can quickly replace tools for different bending applications, making it ideal for flexible manufacturing and multi-batch production environments.

Front Support Arms

The Front Support Arms are designed to provide stable support for large and heavy sheet metal workpieces during the bending process. Featuring an adjustable structure and smooth linear guide movement, they help operators position materials accurately while reducing handling effort and improving production efficiency.

Engineered for CNC press brake applications, the support arms effectively prevent sheet deformation, scratching and misalignment when processing long metal sheets. Their robust construction ensures reliable performance in demanding industrial environments.

CNC Follower Support（Optional）

The Motorized Sheet Follower Support is designed to automatically support large and heavy sheet metal workpieces during the bending process. Synchronized with the CNC press brake, it follows the movement of the bending angle in real time, preventing material sagging, deformation and surface scratches.

Powered by a servo-driven system, the sheet follower significantly improves bending accuracy, reduces operator workload and enhances production efficiency when processing long or thick metal sheets. It is especially suitable for automated and high-precision sheet metal fabrication.

Electro-Hydraulic Proportional Valve

The Electro-Hydraulic Proportional Valve is one of the core components of a CNC press brake, responsible for precisely controlling hydraulic pressure and ram movement. Working together with the CNC controller and linear scales, it ensures accurate synchronization of both cylinders, delivering exceptional bending precision and repeatability.

Featuring fast response speed and stable hydraulic performance, the proportional valve continuously adjusts oil flow and pressure in real time, enabling smooth machine operation and consistent bending results even during complex multi-step bending applications.

Hydraulic Filtration System

Linear Scale (Grating Ruler)

The Linear Scale (Grating Ruler) provides real-time position feedback to the CNC controller, ensuring precise ram synchronization and high bending accuracy. Working with the electro-hydraulic control system, it delivers excellent repeatability and stable performance for demanding sheet metal bending applications.

Hydraulic Motor

The Hydraulic Motor is the power source of the CNC press brake hydraulic system, providing stable and efficient energy for the machine's bending operations. Combined with a high-performance hydraulic pump, it ensures smooth oil flow, consistent pressure output and reliable machine performance under continuous production conditions.

Designed for heavy-duty industrial applications, the hydraulic motor delivers powerful driving force while maintaining low noise, high efficiency and long service life. Its stable operation is essential for achieving precise bending accuracy and reliable hydraulic control.

Servo Motor（Optional）

The Servo Motor is a key component of the CNC press brake automation system, providing precise and efficient control of the backgauge and axis movements. Featuring high positioning accuracy, fast response speed and stable operation, it ensures smooth machine performance and consistent bending results.

Compared with conventional motors, the servo motor offers greater energy efficiency, higher accuracy and improved production productivity. Combined with the CNC control system, it enables automatic positioning, reduced setup time and enhanced overall machine performance.

Backgauge Fingers

The Backgauge Fingers are designed to accurately position sheet metal before bending, ensuring consistent dimensions and improved bending accuracy. Mounted on the backgauge beam, they provide stable support and reliable positioning for various sheet metal fabrication applications.

Built with durable materials and precision machining, the backgauge fingers help operators achieve repeatable bending results while improving production efficiency and reducing manual measurement errors.

CNC Movable Backgauge Finger (Z1/Z2 Axis)（Optional）

The CNC Movable Backgauge Finger is an essential component of the multi-axis backgauge system, designed to automatically position the backgauge fingers along the X-axis according to programmed part dimensions. Controlled by the CNC system and driven by a high-precision servo motor, the Z1/Z2 axis backgauge fingers provide accurate sheet positioning for complex bending applications and multiple flange lengths.
