Makino a81 HORIZONTAL MACHINING CENTER

Technical Description

The 2012 Makino A81 Horizontal Machining Center is a high-performance CNC machine designed for precision and efficiency in demanding production environments. Featuring a robust construction and advanced engineering, the A81 delivers reliable operation for complex machining tasks across industries such as aerospace, automotive, and heavy equipment manufacturing. The machine is equipped with a 24.8" x 24.8" pallet, capable of supporting workpieces up to 2,640 lbs, making it ideal for large and heavy components. Its axis travels measure 35.4" (X), 31.5" (Y), and 40.1" (Z), providing a generous work envelope for versatile part processing. The full B-axis enables 360-degree indexing, allowing for multi-sided machining and improved part accuracy. The spindle utilizes a CAT 50 tool holder, operates at speeds up to 10,000 rpm, and is powered by a 33.5 hp motor, ensuring high-speed cutting and excellent material removal rates. The 60-station automatic tool changer (ATC) streamlines production by minimizing tool change times and maximizing uptime. The A81 features a Fanuc 31i control system for precise and intuitive operation, along with high-pressure coolant through the spindle for enhanced chip evacuation and tool life. Additional standard features include a chip conveyor, coolant tank, and pumps, supporting continuous and efficient machining cycles. The machine’s rigid bed castings and three-point support system contribute to exceptional stability and accuracy, even during heavy cutting operations. With its combination of large work capacity, advanced spindle technology, and automation features, the Makino A81 is a versatile and reliable solution for high-volume, high-precision manufacturing applications.
