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 trapdoor, which can be fitted optionally with a steel chip conveyor belt.
Drilling module


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°.
Milling unit
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.
Horizontal cutting module
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
