NC 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 synchro hydraulic press brake is good for bending sheet metal plate in the factories. It is a cost effective choice in steel structure industry, rough machining factories, truck manufacturing industry etc...
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.
Synchro control system
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.

Advanced Snychro Control System
Bambeocnc 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
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 Carbinet and Components
All press brakes from Bambeocnc includes both NC Torsion Bar Synchro press brake and CNC press brake adopt Schneider electrical components: high quality electric parts can performwell even the electricity is not stable and customers can easily get the replacement any where in the world.
Also, the electric carbinet with ABB Door Open Power Off Component to ensure the operating safety.
