Machining centre with up to 20 CNC axes, designed to perform cutting, milling and drilling operations, including head and tail, on aluminum and light alloy profiles. +QUADRA is a configurable line with modular solutions and custom packages that allow to satisfy the most common applications in window and doors, architecture and industry sectors. The structure of the line includes an automatic feeding magazine from which the profile is picked up and transferred to the operating section. It contains the units for cutting and machining; then an extraction system deposits the finished pieces on an accumulation magazine. The three main modules include a number of variants that modify the vocation of the line in terms of flexibility, automation and productivity. The loading magazine, designed for profiles up to 7.500 or 9.500 mm, collaborates with a push-feeding system assisted by the movement of an automatic positioning gripper for clamping and transfer of the profile in the operating unit. The positioning of the next bar in the loading area is synchronized with the return of the transport gripper which occurs in masked time. The highly-flexible FLW version optimizes the loading of the profiles by occupying the entire surface of the bench and increasing the load capacity. It is combined with the PROFIX dynamic counterblock system which guarantees correct reference and orientation of the profiles for subsequent machining. The 4-axis NC milling module includes from 4 to 8 electrospindles on a rotary base that allow to machine all the faces of the profile, regardless of its orientation. Two units are available for cutting, one with a Ø 600 mm blade with down-stroking movement on three CN axes and one with a Ø 350 blade with horizontal movement on three CN axes, also designed for simultaneous installation. The configuration opportunities are completed by an end milling module operating on two NC axes by means of a milling unit or, alternatively, a 4-axis module for milling the head and tail of the workpiece. A cabin encloses all the work units, ensuring a high standard of soundproofing and total operator protection. The AES adaptive extraction system picks up and transfers the machined segment from the cutting unit to the unloading magazine. The unloading unit consists of a magazine with transversal belts and is available in various widths for profiles with maximum length up to 4.000 or 7.500 mm. The accumulation magazine can be configured in the high-capacity HCS version that allows to contain the entire volume of profiles present on the loading magazine without operator intervention. The equipment of the machining centre is completed by the ALM labelling module with automatic positioner, to identify the machined pieces, and a tool integrity control system. Both optional devices, combined with capacious storage magazines and the reliability of Emmegi systems, allow the machine to be exploited over extended machining cycles in fully automatic mode.

The core and value of the +QUADRA lies in its rotary base machining section, complete with 4 machining units for +Quadra L0 and 6, or 8 machining units for +Quadra L1 and +Quadra L2, that are controlled and can be interpolated on 4 axes: X, Y, Z, A (360° slewing around the axis of the bar). The work units are fitted with air-cooled high-frequency electrospindles, ER 32 tool connector with power up to 5.6 kW in S1. Each work unit can be equipped with an area disengagement system, by means of recirculating ball slides to increase the working capacity.
The vices are equipped with elements that are positioned through CNC to allow perfect bar clamping. Thanks to the possibility of programming specific settings for a range of profiles, the machine recognises the selection and, according to the geometry, sets the vices and their pressure in optimal way, by limiting the need for specific counterblocks. This solution allows to significantly reduce setting times and increases productivity. The new multichannel management logic of the machine allows the optimisation of machining cycles by increasing efficiency.
Drilling unit on 4-axis CNC designed for machining at head and end of profile at any angle. Interacts with the horizontal cutting unit, with which it shares the support beam. The cutting and drilling modules enable unloading swarf into a special opening, which can be fitted optionally with a steel evacuation belt.
Numerically controlled, high precision and high speed bar positioning system. The system is complete with a gripper to block and transport the profile with automatic horizontal and vertical position adjustment and, optionally, the rotation on two CNC axes. A profile lifting system during feeding allows loading in concurrent operation time, with significant reduction of the cycle time. The belt loading magazine is used for loading profiles with length of up to 7.5 m (9.5 m as optional) and weight up to 120 kg. If required by the cycle, during loading and unloading, a tilting system automatically rotates the workpiece 90°.
The high-performance industrial PC significantly improves the computing power of the operating system and the speed of the application software installed. This device allows to achieve a reduction in machine set-up time and manage the most complex cycles without slowdowns.
