1. Electrical system
   1. The machine adopts 380V, three-phase four-wire power supply.
   2. Electrical components and materials are in line with national standards.

The main circuit of the motor is provided with short circuit, overload and phase loss protection. 

1. Hydraulic system,synchronization technology and crowning technology                          

1)  Hydraulic system
The German AGRO company proportional servo valve drive can guarantee extremely high synchronization control precision. The integrated hydraulic control system simplifies the pipeline, prevents leakage, improves the stability of the machine tool, and also makes the appearance more simple and beautiful. The internal gear pump ensures low noise and long service life of the whole system.     

2)  Synchronization technology                                  
The position of the slider is fed back to the NUMERICAL control system by the grating ruler on both sides. Then the controller controls the size of the opening and the amount of oil in the cylinder, so as to control the synchronous operation of the slider(Y1,Y2) and keep the parallel state of the working table. The controller automatically controls the deflection compensation of the worktable according to the state of the machine, so as to achieve the uniform and consistent effect of the full-length Angle of the work piece.     
3)  Crowning technology                                                                                                    
The automatic crowning system overcomes the influence of the sliding block deformation on the work piece quality in the working process and ensures the good straightness and bending Angle of the work piece.

1. Structure of the machine                                 

1. Rack                                       
   • Beautiful appearance design.
   • The world famous finite element software ANSYS is used for the finite element analysis and optimization design of the main components.
   • The machine is made of sheet plate welded structure with good rigidity.
   • Natural aging and vibration to eliminate internal stress.
   • The structural parts are spayed with anti-rust paint.

The vertical column of the machine tool and the lower table are processed by large milling machine in one time, which insure the parallelism and perpendicularity of each mounting surface.      

• • The bending Angle accuracy can reach±30.
  •  

1. The slider
   • The slide is made of whole steel plate and is fixed with two oil cylinders by connecting shaft.
2. Beam, linear guide,ball screw   
   • High quality beam and famous brand linear guide & ball screw (TBI).
