MAKINO A71NX HORIZONTAL MACHINING CENTER

Technical Description

The MAKINO A71NX Horizontal Machining Center is a high-performance production machine designed for precision and efficiency in metal cutting. It features a robust 50 HP spindle motor delivering up to 10,000 RPM with a CAT 50 spindle taper, supporting heavy-duty machining tasks. The machine offers substantial travel axes with 31.49" (X), 29.53" (Y), and 32.67" (Z), facilitating machining of large workpieces. It includes a dual-pallet system, each pallet measuring 19.7" x 19.7", allowing continuous operation with minimal downtime. The automatic tool changer (ATC) has a capacity of 60 tools, enabling versatile and complex machining setups. Rapid traverse rates reach up to approximately 1,968 inches per minute on all axes, promoting high-speed productivity. The machine supports full 4th-axis pallet indexing, enabling advanced machining operations with precise rotational positioning. Key features include a high-pressure through-spindle coolant system (up to 1,000 PSI) for efficient chip removal and cooling, a Renishaw probing system for in-process inspection, and a chip conveyor for automatic chip management. The sturdy construction minimizes structural deflection for consistent accuracy and high metal removal rates. The machine weighs around 2,200 lbs and has accumulated approximately 2,722 operational hours. This combination of power, precision, and automation makes the MAKINO A71NX suitable for high-volume, high-accuracy production applications in aerospace, automotive, and general manufacturing sectors.
