Hydraulic 4 rolls plate bending machines with NC controller Siemens and pre-bending
Common Characteristics
- Project based on over 60 years’ experience in the production of plate bending machine.
- Structure and components designed to withstand heavy use over the long term with reduced maintenance.
- Structure of thick welded steel.
- Frame work with CNC machines.
- Basement and rods to impart rigidity to the machines.
- Care in selection of material.
- High quality components.
- Electric components and easy electric scheme to reduce the maintenance.
- The machine is fully hydraulic.
- Size of hydraulic systems and components, including hydraulic pistons, higher than necessary to reduce the pressures of work and have a longer life.
- Linear movement of bending rolls with short inter-axes to minimize the flat part on pre-bending.
- Rolls supports linear guides in cast iron, with extra length to enhance lateral movement.
- Double hydraulic motors coupled to planetary gear for rotation of central rolls (upper roller motor with hydraulic unloading device to compensate for the speed).
- Large rolls shaft to assemble oversize capacity bearings and greater support for heavier loads.
- Rolls are assembled on double bearings to improve the tilting in case of cone bending.
- Wide range of series.

NC Controller Siemens
- Complete machine control for automatic production.
- Siemens Panel TP700.
- Rolls movements and rotation with deceleration ramps for accurate positioning of the axis and the repeatability.
- Movement of axis step by step.
- Easy use of NC Control in manual and automatic mode.
- Use in Manual mode with display positioning of rolls and rotation.
- Use in Semi-Automatic mode inserting every single axe movement and setting the NC move it till preselected position.
- Use in Self-learning: production of the work in manual mode than saving of steps and storing after work.
- Use in Automatic mode selecting the programs already stored or typing them directly on the panel, specifying the position of each axis.
- Internal memory up to 100 programs from 30 steps.
- Panel with a SD slot to expand memory and back-up programs.
