Twin head cutting-off machine with 5 NC axes for aluminium, PVC and lightweight alloys, with automatic mobile head movement and electronic management of all angles from 22°30’ (internal) to 45° (external) with a resolution of 280 positions per degree. The 600 mm cemented carbide blades have two different feed modes. Standard feed optimises the cutting chart in the vertical direction for cutting profiles of more than 450 mm in height. Radial mode, protected by one of the several patents covering this machine, makes use of an extremely generous cutting stroke that surpasses the vertical reference surface and produces ample working dimensions in the horizontal direction. This solution allows 45° mitre cuts of profiles of up to 240 mm in width. Blade feed is controlled by two NC axes to ensure optimal adjustment of the blades exit speed and stroke. All axis movements are supported on guideways and recirculating ball shoes. The automatic fully enclosed cutting area guarding, the design of the operator panels, and frontal access to the electric and pneumatic panel, confirm the advanced nature of this machine also from the perspective of safety and ergonomics. PRECISION RS has 5 ultra-high precision NC axes for mobile head positioning, inclination of the two cutting units and for the blades feed movement during cutting operations. Positioning is achieved using an absolute linear magnetic strip measuring system, capable of storing the required position in the memory and dispensing with the need for axes homing procedures. Numerical control of all movements makes it possible to manage all operating parameters – including the blades exit stroke length – from a state-of-the-art touchscreen control console. The HS (High Speed) version envisions an X axis with higher speed and all necessary protections for the automatic work, even unattended.
Inclination of each head of up to 22°30’ inwards is provided by two circular guides mounted on four pairs of steel rollers. This patented solution makes it possible to eliminate obstructions in the cutting area, all to the benefit of profile positioning and clamping, while also offering greater rigidity than traditional systems. The absolute magnetic strip positioning system dispenses with the need for axes homing procedures, with the associated idle times.
Making use of the ample space provided by the use of the virtual axis, clamping of the profile to be cut is performed by two horizontal hold-down devices with extreme precision and in absolute safely. For vertical clamping, particularly for special cuts, the machine can be equipped with a patented system of horizontal hold-down devices. The Precision cutting-off machine can be equipped with a roller conveyor on the mobile head, for standard feeding and unloading, or on the fixed head for feeding from the left-hand side.
The industrial label printer allows each cut profile to be identified with identifying features from the cutting list. In addition, barcode printing enables easy identification of the profile itself, which is particularly useful for subsequent machining steps on Machining Centres or assisted assembly lines.
