Quadra L1

CNC 12-axis machining centre, designed to perform milling, drilling and cutting operations aluminium and light alloys in general. QUADRA L1 is made up of an automatic tool magazine and a thrust feed system for profi les sized up to 7500 mm complete with profi le clamping gripper drive. Due to the movement of the collet, the feeder returns to its initial position thus allowing the loader to prepare the next profi le at the same time. In the central part are situated the milling module and the cutting module. The CNC 4-axis milling module is equipped with 4 up to 6 electrospindles and enables the whole contour of the workpiece to be machined, however it is oriented. The CNC 3-axis cutting module is made up of a Ø 600 mm blade, with down stroking movement. QUADRA L1 also comprises an automatic outfeed unit leading from the cutting unit to the unloading magazine. The unit is made up of a magazine with transverse belts for unloading machined workpieces with a length of up to 4000 mm (7500 mm optional). The machining unit can be fi tted with a cabin (optional) soundproofi ng the central operational part, which not only protects the operator but also reduces the acoustic impact on the environment.

Automatic bar feed and workpiece unloading

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.

Vertical cutting module

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.
