Portal Structure
Symmetrical twin pillar structure offers exceptional stiffness and thermal stability for machining large parts. Optimized casting frame effectively dampens vibration, ensuring extreme precision, excellent surface quality and long tool life in high-speed machining and heavy material removal.
Honeycomb Structure
The internal honeycomb structure of the columns and crossbars maximizes the rigidity and lightness of the frame. This optimized casting effectively dampens vibrations and prevents warping caused by thermal expansion, ensuring exceptional dimensional accuracy and surface quality in large-scale machining.
Enclosure Structure
A massive and rigid enclosure structure is designed to maximize torsional stiffness and effectively dampen vibrations. This optimized casting ensures exceptional stability during heavy blanking, improving dimensional accuracy, extending tool life, and guaranteeing high-quality surface finish in demanding conditions.
Support
A wide and robust saddle support is designed to evenly distribute the load across the entire machining area. This minimizes deflection and ensures exceptional geometric accuracy even when moving heavy parts at high speeds. The structure effectively dampens vibrations, ensuring a high-quality surface finish and extending tool life.
Three-Axis Roller Chains
All axes use robust roller type linear guides that provide a large contact surface and stiffness. They allow for rapid movements and high acceleration while maintaining precise positioning, ensuring efficient and vibration-free machining in demanding high-speed machining.
