Main structure of equipment
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.
3)The main circuit of the motor is provided with short circuit, overload and phase loss protection.
（Electrical wiring diagram-reference)
2.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. |
3.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±30ˊ.
 |
 |
2)The slider
The slide is made of whole steel plate and is fixed with two oil cylinders by connecting shaft.
3)Beam, linear guide,ball screw
High quality beam and famous brand linear guide & ball screw （TBI）.

3.Installation and debugging, technical support and after-sales service
1)The warranty period of the whole machine will be 12 months (except for wearing parts).The warranty period is calculated from the date of delivery.
2)In case of any components failure during the warranty period, we are ready to provide telephone and/or online support. If necessary, our technicians are ready to go to your side in case of the equipment malfunctions, the customer should bear the cost of the engineer(air tickets, transportation & accommodation)
3) During warranty period, we will deliver the parts for free(including the expenses of parts and transportation) if the parts cannot work due to Non-human reasons.
4.If any part need to be repaired in China, the transportation fees from the customer’s factory to china and the customs clearance fees in China sea port should be borne by the customer, the transportation fees from China to customer’s factory should be borne by the supplier.
5.Service after the warranty period: we provide continuous services and support for our customers when the warranty period is expired, the customer should bear the expenses of air tickets, parts cost, accommodation and engineer cost(100usd/day/person).
The buyer needs to prepare the following in advance
1)The foundation of machine shall be prepared according to drawings from the supplier.
2)When the machine arrives at the site, the buyer should cooperate with the seller to provide the corresponding lifting equipment, hydraulic oil, electricity and other necessary conditions and parts.
