Makino A55-E HORIZONTAL MACHINING CENTER

Technical Description

The 2001 Makino A55-E is a precision horizontal machining center engineered for high-speed production work across aerospace, medical, and automotive industries. This robust machine features dual 15.75-inch square pallets, each capable of supporting workpieces up to 1,100 pounds, enabling efficient multi-part production cycles without interrupting machine operations. The machine delivers substantial work envelope capabilities with 22.05 inches of travel on both X and Y axes and 23.6 inches on the Z-axis, accommodating complex geometries and larger components. The spindle operates across a 50 to 14,000 RPM range with a CAT40 taper, providing versatility for both finishing and roughing operations while maintaining rigidity. Full 4th-axis continuous contouring capability enables simultaneous five-axis machining for intricate contoured surfaces. Rapid traverse rates reach 3,307 IPM across all axes, minimizing non-cutting cycle time and maximizing productivity. The machine achieves exceptional positioning accuracy with 0.001-degree pallet indexing resolution, critical for precision applications requiring tight tolerances. Spindle center-to-table clearance ranges from 3.1 to 25.2 inches, accommodating varied workpiece heights and clamping configurations. Equipped with a Professional 3 Fanuc CNC control system, the machine incorporates modern automation features including automatic tool length measurement, chip conveyor systems, and high-pressure coolant-through-spindle capability at 1,000 PSI for enhanced tool life and surface finish quality. The 60-tool automatic tool changer with 2-second tool change cycles ensures maximum uptime and production efficiency. This machine represents proven, mid-range horizontal machining capability suitable for demanding production environments.
