Electro-Hydraulic Servo CNC Press Brake






The cylinder mounting planes on the press brake frame are key datums for left/right cylinder synchronization and consistent bending angles. A high-precision portable CMM samples multiple points on the Y1 and Y2 cylinder contact surfaces, controlling flatness to 0.001mm. This eliminates planar deviations caused by machining stress and ensures gap-free cylinder assembly, maintaining stable bending angles over long service, reducing sway and angle drift, and extending precision service life.






Perpendicularity between the cylinder mounting surfaces and worktable is a key geometric datum. The Y1 and Y2 mounting datums are measured separately against the table to strictly control right-angle deviation. Errors can cause diagonal bending errors, sheet movement and unequal angles along different edges. Strict perpendicularity control keeps cylinder force normal to the table and balanced on both sides, eliminates inherent geometric errors, and maintains diagonal accuracy and angle stability over long use.



Efficient cooling keeps hydraulic oil stable in the optimal 40℃ range. It prevents viscosity loss, seal aging and pressure instability caused by rising oil temperature, maintaining stable output during continuous operation, consistent bending accuracy and longer life for hydraulic components and oil.



Backgauge System

The support structure combines rigidity and resistance to off-center loads, remaining stable during thick-plate bending with less drift and vibration. Precision drive screws ensure accurate, smooth backgauge positioning, maintaining dimensional accuracy and consistent forming during sustained heavy-duty work and supporting reliable long-term operation of high-tonnage equipment.



Two guide rails share the moving backgauge load, replacing conventional single-rail, single-point loading. High-rigidity steel rails strengthen the structure and resist beam sag and drift over long travel and under heavy loads. High-speed reciprocating positioning stays smooth with less vibration.
Premium CNC press brake options include laser safety protection and laser precision devices. They protect the bending area and correct bending accuracy in real time. Compatible with multiple CNC press brake series, they are ideal for upgrading sheet metal equipment.
Improves operating convenience and workpiece positioning accuracy. Scans hazardous areas in real time without physically obstructed blind spots.
Three laser beams work independently and are evaluated jointly by intelligent algorithms, providing seamless coverage of the detection area.
Real-time laser angle measurement with dynamic compensation eliminates repeated test bends and machine adjustment.


Automates sheet loading, bending support, flipping and finished-part unloading, avoiding manual handling risks for heavy plate. Continuous unattended operation integrates closely with the press brake control system, maintaining heavy-workpiece accuracy and unlocking high-tonnage production capacity.
