Slider synchronization control
It adopts advanced electro-hydraulic synchronous closed-loop technology. Y1-Y2 axis is the independent motion axis of two sliders controlled by the numerial control system. Two magnetic scales are installed at both ends of the machine tool, which are used to determine the exact distance between the slide and the table, and the magnetic scale is connected to the table through the frame(c-frame), which minimizes the influence of column deformation on the position of the slide. The position data when the slider is running is immediately fed back to the numerical control system, which can measure and output the servo valve control signal S1-S2, control the output flow of the two electro-hydraulic servo valves, and synchronize the two cylinders, and this position measurement process is closed-loop control. The use of electro-hydraulic synchronization technology can make the machine have anti-bias load force and have eccentric load processing capablities.

Hydraulic system
1.The proportional servo valve drive using German technology can obtain extremely high synchronous control accuracy.
2. The sealing ring is selected from Japan NOK, which has good sealing performance, reliable work and long.

1. The pipe joint adopts the original American PARKER or EATON to ensure that the hydraulic system has no leakage.
2. There is a clear and intuitive oil level height and temperature display.
3. It adopts integrated design, compact structure, strong sealing performance and long life.
4. The hydraulic system adopts precision filtration, and filtration accuracy is high.
5. The hydraulic system has overload protection function.

The rear gear is driven by the servo motor through the synchronous belt synchronous wheel to the drive the ball screw to drive the rear gear material, and is carried by four linear guide rails, which has the characteristics of high repeated positioning accuracy, reliable structure, fast positioning speed, low noise and vibration, and high bearing capacity.
The standard R-axis lifting has a high advantage when bending complex workpieces, and transmission part is shielded by a safety cover, which can be used in one feel swoop.(the blocking system is an exclusive patented technology), and the large tonnage is matched with a series of heavy-duty materials.

This machine is suitable for aircraft, shipbuilding, automobiles, electrical appliances and other factories, construction, decoration and other industries and lamp pole production. High production efficiency. When bending sheets of different thicknesses, only need to select the "V" groove under die with different opening sizes, generally the selected opening is 6~10 times of the plate thickness. For example, when bending a 6mm plate, you can choose a 36-60mm groove


The machine tool is mainly composed of frame, slider, backstop system, hydraulic system, control system and mold.
