Machining large monolithic aluminum structural parts for aerospace requires a machine that combines extreme rigidity, thermal stability and high-speed capability. COMI GROUP MONNALISA is a 5-axis horizontal gantry milling center developed specifically for large-dimension aluminum structural parts, particularly suited for aerospace applications. X-axis travel reaches 4,000mm with Y-axis 2,000mm and Z-axis 1,200mm. The 120-tool automatic tool changer and dual-pallet exchange table (3,200×2,000mm) enable continuous production with part loading during machining cycles. Cast iron construction with PT100 thermal sensors and Heidenhain optical encoders ensures minimal thermal drift.

What size aerospace parts can the MONNALISA handle?

Aerospace structural components like fuselage frames, wing ribs and bulkheads often exceed 3 meters in length. The MONNALISA handles parts up to 4,000mm in X-axis, 2,000mm in Y-axis and 1,200mm in Z-axis. The dual-pallet exchange table (3,200×2,000mm) allows loading of the next workpiece on one pallet while machining continues on the other – eliminating setup downtime. This replaces 3-axis machines that require multiple setups and repositioning for large structural parts.

What makes the MONNALISA suitable for aluminum structural machining?

Aluminum aerospace parts require high spindle speeds for productive material removal and extreme rigidity to maintain accuracy across large travels. The MONNALISA delivers 30,000 rpm spindle speed with 90-120 kW power for aggressive aluminum cutting. The cast iron structure with strategic reinforcements provides rigidity and dynamics with minimal thermal drift – PT100 temperature sensors monitor and compensate for thermal expansion. The X carriage uses four gearboxes with integrated pinion and four brushless motors, with twin drive systems that recover any backlash through electronic preload. This replaces lower-speed machines that cannot achieve productive material removal rates in aluminum.
