Egypt Tandem CNC Press Brake Machine For Sale ordered by the distributor has completed production and commissioning and is ready to be shipped to the Egyptian customer's factory. The Egyptian distributor ordered SC-2WDK 130Ton 3200MM tandem hybrid servo press brake machine.
SHENCHONG 2WDK-130T 3200MM Tandem CNC Press Brake consists of two 130ton 3200mm hybrid servo CNC bending machines, linked and controlled by a high-precision CNC synchronous system. It can operate in two modes: simultaneous processing of both machines or independent operation of one machine, depending on processing requirements.
This equipment is mainly designed for large sheet metal, extra-long workpieces, and high-precision mass production. It is an important piece of equipment in industries such as wind power, power equipment, rail transportation, construction machinery, building curtain walls, and communication cabinets. The dual-machine linkage technology allows the two machines to be used as one extra-long bending machine while retaining the flexibility of single-machine processing, significantly improving equipment utilization.

Dual-machine linkage is not simply placing two bending machines together, but rather achieving synchronous control using a unified CNC system.
The entire system mainly consists of:
- Dual machine frames
- Electro-hydraulic servo system
- Linear ruler detection system
- CNC controller
- Linkage communication system
- Hydraulic synchronization system
The control system collects in real time:
- Left machine position
- Right machine position
- Left and right cylinder pressure
- Slider speed
- Linear ruler feedback
Then it automatically corrects the errors between the two machines.
Therefore, it ensures:
- Synchronous movement of the left and right sliders
- Consistent bending angles on both sides
- Uniform bending angles across the entire 6400mm section
- No intermediate angle errors on long workpieces
After dual-machine linkage, the two machines are logically equivalent to a single 6400mm large bending machine, enabling one-time bending of ultra-long plates.
This equipment uses a hybrid electric-hydraulic servo drive, which offers higher efficiency and energy savings compared to traditional hydraulic bending machines.
Main components include:
- Dual servo motors
- Bidirectional servo pump
- High-response hydraulic system
- Electro-hydraulic proportional control
- Intelligent pressure control
During operation:
- The servo motors start when action is needed.
- The oil supply stops immediately when action stops.
- No need for continuous circulation in a traditional hydraulic system.
Therefore, it achieves:
- Energy consumption reduced by approximately 40%–60%
- Lower oil temperature
- Less noise
- Faster response
- More precise positioning
Simultaneously, hydraulic oil consumption is significantly reduced, helping to lower maintenance costs and extend the life of hydraulic components.

Multi-process continuous machining
To ensure long-term stable operation of the equipment, it is recommended to establish a comprehensive maintenance system:
- Daily Maintenance: Check hydraulic oil level, lubrication, grating ruler and mold condition; clean the worktable.
- Weekly Maintenance: Check synchronization accuracy, back gauge positioning, tighten bolts and cable connections.
- Monthly Maintenance: Check hydraulic system pressure, filters, oil circuits and electrical system.
- Semi-annual Maintenance: Change hydraulic oil (depending on operating conditions), calibrate the grating ruler, check the servo system and compensation mechanism.
- Annual Maintenance: Perform comprehensive calibration and maintenance on the overall machine's geometric accuracy, synchronization performance and CNC system.
Proper maintenance not only maintains equipment accuracy but also significantly extends the service life of the entire machine and key components.
The Egypt Tandem CNC Press Brake 2WDK-130T 3200MM features large tonnage, extra-long machining range, high precision and high energy efficiency. Its dual-machine linkage technology breaks through the bending length limitations of a single machine, enabling one-time forming of ultra-long plates up to approximately 6400mm in length, while retaining the independent processing capabilities of a single machine, significantly improving equipment utilization and production flexibility.
Combining hybrid electric servo drive, electro-hydraulic closed-loop synchronization, CNC deflection compensation, and intelligent programming systems, this equipment surpasses traditional hydraulic bending machines in processing accuracy, energy efficiency, operational stability, and automation level, making it an ideal bending solution for large-scale sheet metal manufacturing, smart factories, and automated production lines.
