NC hydraulic press brake machines have torsion bar synchronous NC two axis control capability. They are suitable for bend parts at low cost price.

NC torsion bar synchrony hydraulic press brake is good for bending sheet metal plate in the factories.

WC67K Hydraulic NC Press Brake

The entire machine is in fully steel welded structure with stress eliminated by vibration aging technology. The machine mainly consists of the left and right wall boards, working table, oil box, slot steel, synchronizing shaft, sliding block, etc.

It enjoys high accuracy and high strength and can be transported easily. Machine tool have the function of point move, single and continuous, fast and slow area distinguishing slider. Area can be adjusted independently.


The hydraulic press brake adopts integrated hydraulic control system which limits the quantity of pipe connections, thus being more reliable and easy for maintenance.


It also adopts steel torsion bar synchro system with very simple structure but very high accuracy. At both ends of the sliding block, there are 2 synchro folks which make the sliding block movement always parallel to working table. This structure highlights a balanced movement effect during operation. Upper die compensation is used to improve the brake precision.

Advantages and differences:

  • Traditional structure by using the torsion bar synchronize Y axis
  • Standard 3 axis X, Y, R.
  • Standard DELEM DA41 controller.
  • Ball screw and linear guide.
  • Backgauge controlled by servo motor.
  • Standard Lion light curtain protection.
  • Upper punch compensation.

Hydraulic Press Brake Standard Components

  • ESTUN 21 NC Control Unit
  • FIRST Valves (U.S.A)
  • Full length multi V die series of 835mm punches with a fractioned on

It is a cost effective choice in steel structure industry, rough machining factories, truck manufacturing industry etc…

Due to the structure limitation, Wuxi SHENCHONG does not recommend customer to choose torsion bar synchronous press brake when they buy model above 400tons.

Advanced Snychro Control System

Advanced Snychro Control System

Shenchong synchronize torsion bar is two times larger than normal torsion bar, which improve the torsion resistance.

Double hydraulic oil cylinders are applied for upper transmission, provided with mechanical limit stopper and synchronize torsion bar, typical of stable and reliable operation, as well as high precision.

Eccentric shaft can adjust Y axis and X axis of the snychro torsion bar to ensure the torsion bar can perform fine when out of sync.

Press Brake Backguage

Press Brake Backguage

Beam at the back of the slider to adjust the slider X axis straightness

Adjustable template at the bottom of the slider, forecast to adjust the Y axis straightness after deformation

Electric back gauge mechanism has two function of electric and manual adjustment, and the digital display shows back gauge stroke data

Back gauge beam can be adjusted up and down as a whole

Back gauge finger moves around any error within 0.2 mm, and can do positioning adjustment alone.

Electric Cabinet and Components

Electric Cabinet and Components
