Automatic single-head cutting-off machine with upstroke movement for 90° cuts, fitted with N/C electric bar feeding system. Can be configured with four different diameter blades, N/C electric blade feed. The machine can be configured to use blades with two different diameters. The setup requires a very simple operation, after which the software automatically prepares for the correct setting appropriate to the installed blade. For cutting needs requiring a perfect finish, it features, as an optional, a pneumatic system for the automatic separation of the cut piece, which avoids the presence of traces -commonly left by the blade when it moves back - in machines that use this cutting mode. It can also be configured with an inverter to change the blade rotation speed, adapting it to the profile to be cut. It can be equipped with a large automatic bar loading magazine; an unloading magazine with conveyor belt for extraction of cut workpieces and accumulation bench; customisable drilling and milling units for specific needs. Thanks to its wide range of accessories, this machine can be configured as a real fully automatic cutting-off centre capable, in addition, of performing drilling and milling machining thanks to specific customised units.
Bar feed system obtained through the use of a controlled axis ensuring, through the use of a recirculating ball screw, high positioning accuracy. It can be set from the PC on board the machine. Equipped with a bridge vice system, which allows the extreme versatility of clamping toward a wide variety of profile geometries, while maintaining rapidity in setting up the workpiece clamping cylinders. The system provides 3 automatic positions, integrated in the machining cycle, so as to avoid profile scraping with the machine reference planes during the various phases of feeder movement.
To enable maximum utilization of the large cutting capacity, which ensures the machinability of large profiles, the cutting zone features a sturdy structure designed to ensure maximum precision. This is with regard to both the horizontal plane and the vertical square. The bridge vice system also present in the cutting zone, with its 4 positionable hold-down devices, contributes to stable and precise clamping of the workpiece.
Optionally, both bridge vices can be equipped with adjustable hold-down devices, with adjustable pressure angle. This is an accessory that enables the proper clamping and cutting of profiles with irregular geometry, ensuring maximum rigidity and the maintenance of precision, a distinctive feature of the machine itself. The use of this system is also characterised by simplicity and quick set-up.
Integral work area protection ensures maximum safety during cutting cycles. It consists of two separate protective covers, one for the workpiece clamping and transport area and one for the clamping, cutting and separation area. The two covers have a large scratch-resistant polycarbonate window to follow the machining in full brightness and visibility. They are independent of each other and slide to the outer sides of the machine giving wide and complete access to the workbench.
The control area features a control console equipped with a PLC with an integrated 7" colour TFT graphical display and fully customised, feature-rich software designed specifically for this machine. Single cuts or cuts from list can be programmed locally through the PLC. Using connection via USB port or LAN connection, programmed lists can be used remotely. Cutting management control is complemented by the ability to adjust the blade output speed.
The machine can be configured to use interchangeable blades with two different diameters. the tooling simply requires quick assembly of the second blade; the software detects blade changeover and automatically prepares for the correct setting of the different feeding stroke and possible different blade thickness. Only two blades can be configured, the blade with larger diameter is considered by the system as the main blade.
The unloading unit is equipped with a conveyor belt for extraction of the cut workpiece and a translation system to automatically move it from the conveyor belt to the accumulation surface. the unit allows unloading workpieces with length up to 2.5 m or 3.2 m (depending on the version) on a surface with a depth of 1.5 m. The unloading unit, combined with the automatic bar loading magazine, allows creating a fully automatic cutting-off centre.
