CNC 18-axis automatic machining line, built for milling, drilling, cutting and screwing PVC profiles. The line can be equipped with contouring module for preparation of PVC profile to the welding with Seamless® technology. SBZ SL is composed with an automatic magazine with a throughfeed system for profiles, complete with gripper movement to block the profile. Thanks to the movement of the gripper, the feeder returns to the start position allowing the loader to prepare the next profile at the same time. A dimensional control system of the profile section, check if the profile loaded by operator is the correct one according to working job list. The milling module, the cutting module and the contour milling module are located in the SBZ SM unit of the machine. There are 7 or 11 electrospindles installed on the standard CNC 4-axis 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 blade with CNC 3-axis horizontal movement. The contour milling optional module operates on 3 CNC axes by a electro-spindle to mill the profile heads faces cut at 45°. An automatic extractor transfers the workpiece from the cutting unit to the transport magazine. This belt magazine capable of 24 positions transfers the profiles from the SBZ SM unit to the SBZ SF2 unit for subsequent screwing and drilling operations, providing a pool of processed pieces that perfectly balances the productivity of the two units. The SBZ SF2 unit consists of a double pneumatic horizontal screwing unit, which can be automatically adjusted vertically and horizontally by software, fixes the metal support with self-tapping screws that automatically reach the machine from a loader; a triple drilling unit to make cremonese handle holes; 2 drilling units for montage holes for frames. The unit is composed of a transverse belts magazine to unload machined workpieces of up to 3500 mm in length. The machining units are equipped with sound-proof cabins in the operating part, which, besides protecting the operator, reduce the environmental noise impact. The cabin of SBZ SM presents a connection to swarf exhauster (optional). PVC waste and swarf are collected into 2 drawers at the base of the machining module that combined to a belt evacuation system make easier and quicker the cleaning operation.
