SBZ  SF

The SBZ SF2 automatic machining centre for drilling and screwing of metal frames consists of a horizontal screwing centre with 2 screwing units, a triple drilling unit, a single-tool unit for drilling hinges and horizontal units for assembly drilling on all Z- and L-type frames. As an option, it can be equipped with a multi-tool unit for drilling hinges. The SBZ SF2 consists of an automatic magazine with a through-feed system for profiles up to 3500 mm, complete with gripper movement to clamp the profile containing already an aluminium or iron metal support. 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. A pneumatic double horizontal screwing unit is located in the central part and 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 and 2 drilling units for frame mounting holes. The 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 SBZ SF2 can be connected to the SBZ SM machining centre to achieve a continuous process and optimise system productivity. The machine is supplied with an intuitive operator interface for machining list management connected to the production programming software. Industry 4.0 ready.

SBZ SF Screwing unit Someco
Screwing unit
The machine is equipped with 2 pneumatic screwing units with automatic feeding, fitted on a rotary base with automatic movements on 2 NC axes. One unit is dedicated to screwing the reinforcement into profiles for sashes, the other machines profiles for frames.
Drilling unit for wall mounting
Two drilling units, which are parallel to the screwing units, are used to perform machining operations intended for wall mounting of frames.

The drilling for mounting the handle is carried out by a unit with three drill bits located in the lower part of the rotary base dedicated to machining operations.
Installation in line with the SBZ SM machining centre
The maximum potential of this screwing centre is expressed by its perfect compatibility when installed in line with the SBZ SM machining centre. The wide range of machining processes of the machining centre, including profile preparation to allow Seamless welding, are completed with the screwing centre, in a balanced and efficient line.
