18-axis CNC machining centre for milling, drilling and cutting aluminium and light alloy profiles. QUADRA L2 is composed of an automatic magazine and a push feed system for profiles of up to 7500 mm in length, complete with gripper drive for profile clamping. Thanks to the gripper movement, the feeder returns to its starting position simultaneously allowing the loader to prepare the next profile. The milling module, the two cutting modules and the end milling module are located in the central area of the machine. The 4-axis CNC milling module is equipped with from 4 to 6 electrospindles that make it possible to machine any face of the workpiece irrespective of its orientation. The main cutting module is composed of a 600 mm diameter blade with downstroke movement in three CNC axes. The secondary cutting module is equipped with a 350 mm diameter blade with feed and rotation movements on a horizontal CNC axis. The end milling module operates on two CNC axes by means of a cutters unit. QUADRA L2 also includes an automatic ejector to transfer the workpiece from the cutting unit to the unloading magazine. The unit is composed of a transverse belts magazine to unload machined workpieces of up to 4000 mm in length (optional 7500 mm). The central machining area of the machine features a sound-proofed enclosure that protects the operator while also reducing the environmental noise impact.
Numerically controlled, high precision and high speed bar positioning system. The system is complete with a gripper to block the profile with automatic horizontal and vertical position adjustment on two CNC axes. To guarantee that each type of profile is grasped with no manual intervention, the numerical control of the gripper slewing axis is also available, which is otherwise handled manually. The loading and unloading belt magazines are used to load profiles with length of up to 7.5 m and offload lengths of up to 4.0 m, with an option for 7.5 m. If required, during loading and unloading, an optional tipping system can automatically rotate the workpiece by 90°.
QUADRA L3 is fitted with an exclusive turntable system on which 4 to 6 work units interpolated on 4 axes can operate at the same time: X, Y, Z, A (360° slewing around the axis of the bar). The high-frequency electrospindles are air- cooled, and include an ER 32 tool connector with power up to 5.6 kW in S1. Each unit is equipped with a working field disengagement system by means of a slide on recirculating ball shoes.
The CNC-operated cutting module includes a 600 mm diameter circular blade with downward movement on 3 axes, with a range from -45° to +245°, allowing a variety of extruded profile end milling types. The clamping and handling of the segments is done by means of two servocontrolled clamp units on CNC axes.
Single head cutting unit with numerically controlled horizontal feed, with 350 mm blade and a wide cutting range: -45° to +45°. The setting of any cutting angle is fully automatic and controlled by a 3-axis CNC movement. The horizontal feed allows the machine to cut large bars and execute special cuts
End milling unit with cutter unit with variable rotation speed up to 8,000 rpm. With quick cutter unit tool change with pneumatic con- trol. Interacts with the horizontal cutting unit, with which it shares the support beam. The three cutting and end milling modules are used to unload rejects into an opening, which can be fitted optionally with a steel evacuation belt.
