The meticulously designed and assembled structural components in Breton, together with the latest generation of Siemens motors and electronics, take Breton Winger to the top of reliability in its product category. This contouring machine has been designed taking into account the overall costs over the entire life cycle of the machine. The focus has been on minimising downtime and using long-life components to maximise productivity. The result is a significant cost saving for the user when taking into account the entire production life of the product. The powerful standard 15 kW spindle provides all the power and torque needed without overloading, so there is no stress on the components, thus extending their life and keeping them running like new. The tool store is enclosed to protect the tools from dust and liquid that could compromise tool life and accuracy. 

 

 

 

The monoblock structure, with a low centre of gravity and integrated collection tank, guarantees robustness and at the same time eliminates the risk of inaccuracies due to the coupling of parts. The beam, before being machined to the nearest centimetre on the machine tool, undergoes stress-relieving heat treatments to ensure its dimensional stability over time. The movement of the three linear axes through rack and pinion systems guarantees both precision and high positioning speeds. These benefits are amplified on the beam equipped with a gantry system with two motors, one on each side, a solution that eliminates the problems of torsional bending associated with the traditional mechanical axis. The hardened and ground linear guides do not require adjustment and guarantee high precision over a long period of time. 

 

 

 

Winger is available in three models that differ in increasing workbench size, up to 4000 × 3750 mm. The larger the available surface area, the more workpieces can be loaded into the machine, thus speeding up machining thanks to optimised tool paths and tool changes. The Metalquartz top stands out for its great stability compared to traditional metal benches and is also resistant to oxidation. Its special composition, a compound based mainly on quartz, guarantees complete dimensional stability as it is not subject to expansion caused by variations in temperature. If levelling is necessary, its residue can be treated together with the normal machine slurry and the operation can be carried out with the same tools used on the machine for normal machining. 

 

 

This system replaces the operator in positioning the vacuum cups on the table. The spindle automatically picks up the vacuum cups from the special store and positions them on the work table in correspondence with the valve and according to the workpiece and the machining operations to be carried out. The main advantage is that positioning is performed extremely precisely by the machine, eliminating the risk of damaging the vacuum cups and consequently the workpieces. The Robocup vacuum cups do not use electricity or pipes, but are clamped by means of valves on the table. In addition to vacuum cups of various sizes, a special folding vacuum cup is also available, which allows the cutting residues to be lowered automatically so the finishing process can continue without interrupting the cycle. The system stands out in terms of reliability and durability, having been specially designed and tested to work in wet environments with a large amount of solid cutting waste. 

 

 

 

Safety has always been a key point in Breton products. Winger is completely enclosed by fairings to protect the operator on all sides as well as any nearby items. The front doors are characterised by large windows to allow a complete view of the machining operations. The tank positioned underneath the bench is designed to collect all the water used for machining and convey it to the recycling system. In this way the floor remains completely dry, eliminating the risk of slipping or electric shocks, while also avoiding water waste and environmental pollution.
