QUADRA L3

Technical data

20-axis CNC machining centre for milling, drilling and cutting operations at head and end of profiles in aluminium and light alloys. QUADRA L3 is composed of an automatic magazine and a push-feed system for extruded profiles of up to 7500 mm, complete with gripper handling for clamping and traversing the profile in the operating unit.

Automation enables loading the next bar by synchronising its feed with the simultaneous return of the gripper for the next pick-up. The milling module, cutting module and drilling module for head and end are located in the central part. The 4-axis CNC milling module is equipped with 4 to 6 electrospindles that make it possible to machine any side of the profile, regardless of its orientation.

The main cutting module is composed of a 600 mm diameter blade with downstroke movement in three CNC axes. The secondary module operating on 4 CNC axes is equipped with a dual drilling unit that can machine on profile heads. QUADRA L3 is equipped with an automatic ejector to transfer the machined segment from the cutting unit to the unloading magazine.

The unloading unit is composed of a transverse belts magazine and handles profiles with a maximum length of 4000 mm (optional 7500 mm). The central cab contains all work units, ensuring a high soundproofing standard and complete protection for the operator.

ESTIMATE REQUEST

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 CN 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 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 toolholder with power up to 5.6 kW in S1. Each unit is equipped with a work area 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 -48° to +245°, allowing a variety of extruded profile end milling types. The clamping and handling of the segments are done by means of two motorised vice 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 CN movement. The horizontal feed allows cutting large profiles and performing special cuts.

MILLING MODULE

 

Milling unit on 4-axis CNC designed for machining at profile head and tail ends at any angle. Interacts with the horizontal cutting unit, with which it shares the support beam. The cutting and milling modules enable unloading swarf into a special hatch, which can be fitted optionally with a steel evacuation belt.
