SBZ  SM

13-axis through-feed bar CNC machining centre for milling, drilling and cutting, specialising in the production of PVC window frames. The unit can be equipped with an integrated contouring module for preparing the PVC profile for welding with Seamless® technology. SBZ SM 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 central area of the machine. There are 7, 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°. SBZ SM also includes an automatic extractor to transfer the workpiece from the cutting unit to the unloading magazine. This unit consists of a transversal belt magazine for the unloading of machined workpieces long up to 3500 mm. The machining unit is equipped with a soundproofed cabin in the central operating part which, in addition to protecting the operator, also reduces the environmental noise impact. The cabin 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 machine is supplied with an intuitive operator interface for machining list management connected to the production programming software. Industry 4.0 ready.

SBZ SM Ergonomics and easy programming Someco
Ergonomics and easy programming

Simple and ergonomic operator interface. 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 communicate with the SBZ SM machining centre.

Seamless technology (Optional)
The CONTOUR module can be integrated in the profile machining process. An intuitive and efficient software allows defining the machining paths by interpolation of the profile edge in order to obtain a zero-seam welding with Seamless counterblock technology. Contouring programmes can be differentiated based on the colour and film of the different types of profile.

SBZ SM Radio barcode reader Someco
Radio barcode reader (Optional)

The radio barcode reader automatically recognises the piece by means of the barcode label. Any workpiece can be loaded into the machine and the machining centre automatically prepares to perform all machining operations by reading the barcode on the label applied, greatly reducing cycle times and with no possibility of error. The radio barcode reader allows to move freely into working area by performing wireless data transmission with maximum practicality for the operator.
