Mössner supplies fully automatic slab saw to Gränges
August Mössner GmbH + Co. KG delivered a fully automatic slab saw to Gränges Konin, Poland, in spring 2021.
The slab saw from Mössner is characterised by solid steel construction, precise cutting and long band saw life.
In the fully automated process, an average of six slabs per hour are sawn.
Turnkey delivery
The set-up and commissioning took place as a turnkey project with Mössner’s experienced employees in the fields of mechanics, electrics and software.
After successful final acceptance, the Gränges sawing system was handed over for the start of series production.
Equipped with fully automatic test disc manipulator
The aluminium slabs are fed vertically to the system with a crane and aligned horizontally using the turning-down unit.
The slab is transported by a shuttle from the storage area to other buffer areas with integrated scales. After weighing, the slab is placed by the shuttle on the roller table of the sawing system.
To ensure the high cutting tolerances of the customer Gränges, the slab is centred and fine positioned by two clamps.
Fully automatic sawing process
After reaching the sawing position, the first step is to make the head cut by the Mössner high-performance band saw. Due to the stable design of the saw and the wheel bearing, the saw cut is low in vibration. This has a positive effect on the saw blade life.
The customer benefits from the savings in tool and maintenance costs.
Another advantage is the anti-pinch protection developed by Mössner, which is integrated in the saw table. This prevents the band saw blade from getting trapped between the cut section and slabs.
Seamless removal of sawed sections
The sawed section is transported by the slab to a transfer position. The scrap slider pushes the sawed section onto the belt conveyor in the scrap area. Integrated buffer spaces allow the head and foot pieces to be cut seamlessly without unnecessarily interrupting the sawing process.
Test discs are sawn out of the aluminium slab at regular intervals. The test disc is removed by the fully automatic test disc manipulator newly developed by Mössner.
This ensures seamless and automated quality control.
Weighing and marking
The net weight of the bar is determined by load cells integrated in the output area. Subsequently, both long sides of the slab are marked with heat-resistant paint. The front side is marked by a needle embosser at the end of the output roller conveyor. Different marking and fonts, characters and codes are possible.
The bar is transported by the output shuttle to the storage area and picked up there with a forklift.
Mössner sawing systems in use worldwide
Mössner develops and builds special solutions in the fields of mechanical engineering, automation technology and robotics.
The focus of the portfolio is, among other things, in the field of aluminium technology. Mössner offers precise sawing and milling systems for primary and secondary aluminium production.
These enable the machining of rolling ingots, T-bars, contours, blanks, samples, ingots and plates.
