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.
Loading and unloading on the same side
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.
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.
The industrial label printer allows each cut profile to be identified with identifying features from the cutting list. In addition, barcode printing enables easy identification of the profile itself, which is particularly useful for subsequent machining steps on Machining Centres or assisted assembly lines.
