The M4 series consists in systems for the processing of structural profiles and tubes with an outer diameter up to max 815 mm and length up to 24000 mm.
The FL 400 machine is equipped with 3D or 2D cutting head and is conceived for the processing of round, square and rectangular section tubes automatically loaded by a bundle tube pick-up system, while the open section profiles are loaded by a chain system.
The system core consists in a three-dimensional called "Sphera" that allows any point in a spherical space to be worked: movement takes place along 5 interpolated axes with ball recirculation screws and linear motors. The piece movement along the processing axis are guaranteed by 4 self-centring chucks, able to process different diameters and sections without having to change equipment. The change in the straightness of the piece during processing are compensated by an integrated floating system that allows precision processing, even in case of significant irregularities of the tube, thus avoiding damaging mechanical stresses to the chucks.
4MMS -4 Mobile Mandrels (Chucks) System
The machine is equipped with 4 mobile mandrels (chucks), for tube fixing during loading, tube carrying into the cutting zone and tube unloading. Being equipped with 4 mobile mandrels (chucks), the machine is able to grant the maximum optimisation of logistics operations (loading, unloading) and cutting operations independently from the length of the raw tube. Bystronic Laser 4MMS improves the laser-on time of the machine and optimizes considerably the loading and unloading operation.
Chain loading system
The loading and unloading system consists of chains with V-shaped supports which allow the handling also of profiles and open sections.
The manipulators are placed into the loading and unloading area and enable the tube picking up from the chains and/or bundle and the tube positioning in the mandrels working area through controlled axis movements.
Unloading by chains
The automatic discharge system onto chains enables the unloading of tubes and profiles with minimum length 800mm and max length 14.000mm. The chains are equipped with V supports and the speed can be modified according to the tube diameter and weight.
The tri-dimensional Sphera system allows any point in a spherical space to be worked. The movement along 5 interpolated axes, with recirculating ball screws, ensures high dynamics.
3D cutting head
The head holding the focusing lenses is composed of three motorized bodies and is able to perform bevels and transversal cuts. The stiff and light structure, with high precision motors and transducers, combines maximum speed and precision.
