WADH Hybrid Servo CNC Press Brake

With our USUN press brake WAD series you can obtain an optimal bending process and excellent bending results from the first workpiece. Our bending machine with back gauge driven by servo motor and ball screw,guided by two linear bearings.Optimization design,ensuring machine tool’s design aesthetics,reliable structure, and stable work.


Mechanical Structure

The oil-electric hybrid drive press brake is the latest top technology. Compared with the Electro-hydro synchronous press brake, its hydraulic synchronization work depends on high-power dual servo pumps. Besides, the temperature of the hydraulic oil will not rise during work.

High Accuracy

The WADH series ADH press brake features high precision and high speed. With advanced closed loop and servo hydraulic technology, the slider repeatability and parallel accuracy can reach +/-0.01mm

Hydraulic System

The servo motor drives the oil pump to rotate forward and backward. The flow and pressure are automatically controlled by the oil pump and the servo motor. There is no overflow control. Zero power is consumed during the process waiting time. The motor power consumption is determined by the load.

Hydraulic Servo Pump

The German HOERBIGER hydraulic servo pump is a new hybrid electric drive system with a 70% reduction in fuel tank capacity, a 10% reduction in duty cycle, a 50% increase in energy efficiency and a positioning accuracy of up to 5um.

Hydraulic Oil Tank

The fuel tank volume is small, the hydraulic oil cost is greatly reduced; the oil rises at a low temperature, the risk of oil leakage is reduced, the stability is higher, and the service life of the hydraulic system and the oil cylinder is improved.

Electric System

Adopt Schneider Electric system which is safe, reliable, long-lasting and anti-interference.


Multi Axis

The backgauge of the press brake can equip with at most 6 axis for high accuracy and efficiency performance.

Rear Light Curtain

The rear light curtain will protect the worker behind the machine.

Front Light Curtain

The front light curtain will be very helpful for protecting the fingers of the operators.

Laser Protection

Does not affect the efficiency of the press brake, can completely solve the safety problem.

Manual Crowning

The crowning will compensate for the deflection of the worktable during bending process so as to obtain higher working precision.

Mechanical Crowning

The motorized crowning system will adjust the parallelism and straightness automatically.
