18-axis through-feed bar automatic CNC machining line for milling, drilling, cutting, contouring and screwing reinforcements, specialising in the production of PVC window frames. The machining and cutting unit can be equipped with an integrated contouring module for preparing the PVC profile for welding with Seamless® technology. SBZ SL consists of an automatic magazine with a profile through-feed system, complete with gripper movement for profile clamping. Thanks to the synchronised movement of the gripper and bar magazine, the feeder returns to the start position allowing the loader to prepare the next profile at the same time. The dimensional control system for the profile section allows checking if the profile loaded by the operator is the one indicated in the machining list. The milling module, cutting module and contouring module are located in the SBZ SM unit of the machine. There are 9 or 11 electrospindles installed on the CNC milling module which allow working on the whole edge of the workpiece, whichever way it faces. The cutting module is equipped with a Ø 500 mm blade with CNC 3-axis horizontal movement. The optional contouring module operates on 3 CNC axes by means of an electrospindle that allows milling the ends of the profiles cut at 45°. An automatic extractor transfers the workpiece from the cutting unit to the intermediate unloading magazine. This 36-position belt magazine transfers profiles from the SBZ SM unit to the SBZ SF2 unit, a machining module for metal-reinforced segments, perfectly balancing the productivity of the two units. The SBZ SF2 unit is made up of a pneumatic double horizontal screwing unit that can be automatically adjusted both vertically and horizontally via software. The unit fixes the metal support with self-tapping screws that automatically reach the machine from a loader, a triple drilling unit for drilling holes for cremone bolts, 2 drilling units for frame assembly holes and a single-tool unit for drilling the frame hinges. The unit consists of a transversal belt magazine for the unloading of machined workpieces long up to 3500 mm. The machining units are equipped with soundproofed cabins in the operating part which, in addition to protecting the operator, also reduce the environmental noise impact. The cabin of the SBZ SM can be connected to the swarf exhauster (optional). PVC waste and swarf are collected in 2 drawers at the base of the machining module, which, combined with a belt evacuation system, facilitate and speed up cleaning operations. The line is supplied with an intuitive operator interface for machining list management connected to the production programming software. Industry 4.0 ready.

The line is equipped with a simple and ergonomic user interface, which allows machining the work flows in an efficient and balanced way. The totem has a Wi-Fi antenna for connecting the machine to the network that ensures both interconnection with the production programming, through specific drivers, and remote connection for the management of the technical service in case of need. The software manages worklists from the management system that can be directly connected with the line.
