Hydraulic system:                                                                                                                                   

- Adopt integrated hydraulic control system, more reliable and easy for maintenance.Hydraulic system is from Bosch – Rexroth,Germany.

- Extremely reliable and precise Bosch – Rexroth valves are used for the regulating circuit. Every complete working cycle can be achieved through the control of hydraulic valve.

- All seals in cylinder is PARKER from USA,the most famous brand,good quality and high performance

- Overload overflow protection is outfitted to hydraulic system,which can assure no leakage,and the oil level can be read or seen directly.

-Being able to work under rated load continuously,stable working and high precision.

2. Electrical system and the safety interlock:                                                                 

- Electrical panel with cooling system designed to meet CE Standards and composed of automation and electrical equipments with SIEMENS brand.

-Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.

- Front Side Covers with safety switches, Back light safety guards (Category-4),Foot pedal conforming to CE regulation.

- The machine by the European Union CE certification and ISO quality system certification

3. Synchro control system:                                                                                                               

- Slide synchro system:adopt steel torsion bar synchro system, simple in structure and high in accuracy,ensures the parallelism between beams is used for the synchronism.

- 2 ends of slide has 2 synchro fork which make,The system uses upper die compensation to improve the brake precision.

- The worktable adopts the particular design,reducing the crowning distortion amount of lower tool effectively.

4. Bending depth adjustment and RAM structures:                                       

- The bending accuracy and consistency of the repeatability are achieved by a simple mechanical system of adjustable depth Automatic (digit readout) and motorized (DA41 CNC Control) Adjustable.

- Can move the ram up slowly,which allows the operator to control work piece conveniently.

- Universal fixing-surface of the upper tool can be meeting with the clamping requirement of the tool farthest.

- Hardened and ground standard sectioned top and 4V-Die bottom tools (4x1000 mm sections).

5. Servo motorized Backgauge (standard)                                                                       

- CNC Back gauge system with X axis by AC servo motor driven ball screw shafts and on linear bearings with an accuracy of 0.01mm.

- Back gauge has well enough mechanical strength and rigidity with tank-type gauge structure.

- High-precision ball screw and linear guide-way.Particular finger-stop design,enlarge the range of back gauge.
