CNC Electric Servo Hydraulic Tube Bending Machine

The CNC electric hydraulic pipe bending machines are equipped with up to 12 electric drive axis and the motion controller.All pipe movements are precise controlled by servo electrical and powered by hydraulic.

Energy-Efficient Drives

The drives on all axes are optimized to reduce energy consumption, increase moving speed, improve precision, and ensure higher consistency. The machine also operates at lower noise levels.


User-Friendly Automation

High-level automation and intuitive operation make the machine easy to set up and use. It requires minimal operator skill or experience.


Programmable Tube Bending Control

The all-electric tube bending machine features programmable control to optimize bending operations. The carriage position and rotation can be programmed between bends to achieve the desired 3-D tube shapes.

Industry Applications

The CNC electric hydraulic pipe bending machine is ideal for manufacturers producing:

  • Hydraulic lines

  • Exhaust systems

  • Seat frames

  • Brake and fuel lines

  • Structural components

  • Water lines

  • And more in the automotive industry


Servo-Driven Bending Head

The servo motor directly drives the CNC electric hydraulic bending head, ensuring rigidity and precision. The compact bending head allows complex tube geometries to be produced in a single operation.


Multi-Directional Bending

The machine supports double bending directions and allows jog operation for testing or simulation. This is suitable for individual pieces or small series production.


Advanced Servo System & Axis Control

All models use 9 or more axes driven by absolute servo motors with full electric power. High-precision screw rods, recirculating rollers, and ball guides ensure accurate movements and long service life.


3D CNC Programming Interface

Equipped with 19’’ LCD touch screen (HMI) and 3D CNC software, operators can:

  • Program the machine

  • Simulate and optimize production

  • Monitor bending processes

  • Input 2D/3D files via USB or remote interface


Smart Factory Integration

The machine can connect to Industry 4.0 systems via Modbus, RS-232, RS-485, HART, MPI, or other protocols for smart factory automation.


Mandrel & High Precision Bending

The pipe bending mandrel is servo-driven for precise motion control. The system produces bends with CLR/DIA ratios less than 0.8, including 1xD radius bends and thin-wall tubes. A carriage booster eliminates clamping scars and supports tight bends.


Software & Automation Features

The CNC electric hydraulic pipe bending system includes:

  • Program memory and quick selection

  • 3D pipe bending simulation

  • Defect correction

  • Motion monitoring and assisted design

  • Low operator skill requirement

Valuable upgrades options

  • lAutomatic copper tube feeding system

The automatic pipe feeder to achieve pipe bending from loading to unloading is fully automated with less human operation.When the pipe length is less than 600mm,a push plate type automatic hopper pipe feeder is suggested which stands in the rear and front of the pipe bending machine.When the tube length is more than 600mm, a gantry type automatic tube feeder is suggested which stands on the pipe bending machine.

  • lMulti-radius pipe bends with multi-stack

Up to 5 different variable radii can be bent on the same pipe for great multidimensional bending freedom. Multilevel bending dies are stacked on the same bending shaft while the same pipe share the same clamp die, pressure die, mandrel and wiper die, pipe collet, etc.

  • lDouble tube bending directions for complex bends

Left hand and right hand in process tube bending with an up and down exchangeable bending head for great multidimensional bending freedom. It helps tube bending methods be flexible in all directions in the free space. The pipe bending head is driven by a couple of servo motors and linear rods with precision movements. It helps to reduce pipe post bending processes to reduce operator operations.

  • Pipebending direction of the bending head

Different with double bending directions are on the same machine,a single left-hand pipe bending or right-hand bending is optional.It’s bend the tube in clockwise pipe bending or counterclockwise tube bending.
